Implementing ‘ Awakened Need of Change ’ for Applying Ergonomics to Work System with Macroergonomics Approach in an Industrially Developing Country and its Meta-Reflection

Introduction The significant role of macroergonomics and important subsystems In the 90s’ decade, the interest in ergonomics issues in a wide sense grew in enterprise level, as a result of an increasing awareness of the importance of those matters for corporate core values such as productivity, quality and an inevitable change process [1]. Hendrick is attributed macroergonomics with the formalization of Organizational Design and Management (ODAM) in ergonomics [2]. For many years now (since the early 1980s), ODAM factors become an accepted field of research for ergonomics. For this reason that (‘Historical Development of Macroergonomics’ by Hendrick): Macroergonomics is a top-down sociotechnical system approach to the design of work systems and the application of the overall work-system design of the human–job, human–machine, and human–software interfaces [2,3]. It is the formalization of attention to ODAM factors in ergonomics [4]. Macroergonomics is based on, the sociotechnical systems framework, which dates back to English coal mine studies performed, by Trist and Bamforth of the London Travistock Institute [5]. Hendrick claimed, “Good ergonomics is good economics” and defended this point with 25 case studies showing the business value of macroergonomic interventions work [6]. Experience from Industrialized Countries (ICs) and also Industrially Developing Countries (IDCs) shows that consideration of macroergonomics play a significant role in creating the appropriate working environment in which participants are motivated to participate and better utilize company resources for increasing system productivity, reliability and availability [7-14].


Introduction
The significant role of macroergonomics and important subsystems • Work organizations consist of two independent yet interdependent systems: the technical system (equipment, machinery, chemical processes, etc.) and the social system (individual workers and groups of workers).
• The work system is the basic unit, comprising a set of activities that make up a functioning whole, rather than single jobs and tasks.
• The work group, rather than the individual jobholder, is central.
• Regulation of the system is performed by the group itself, instead of by supervisors (completely counter to Taylor's scientific management notions).
• An individual worker is complementary to the machine, rather than an extension of it.
• In sociotechnical theory, the system is broken into three subsystems: technological, personnel, and job design [16]. The technological sub-system contains the tools, technology, work rules, and processes that convert system inputs into outputs [16].
As illustrated in the Work System Sub-Systems are several important sub-systems, including the personnel sub-system, technological sub-system, organizational job and task design, and the internal and external environments [7,20]. The three major principles behind sociotechnical system theory [21] are: 1) Joint causation (i.e., a characteristic of sociotechnical systems is that they are open systems); 2) Joint optimization (i.e., if the personnel or technological sub-system were to be optimized, the result would be a sub-optimized system); and 3) Joint design (i.e., joint optimization is achieved through joint design. According to Kleiner and Drury, these can be factors of a successful macroergonomic practice [22]. The requirements of each sub-system are considered along with the influence of the environment in designing the system) [16]. There are at least three major characteristics of the personnel sub-system these are sensitive to the design of an organization's work system structure [15]: 1) The degree of professionalism; 2) Demographic characteristics; and 3) Psychosocial aspects of the workforce.
For this reason that the three major sociotechnical system elements include the: (1) Technological subsystem; (2) Personnel subsystem; and (3) Relevant external environment that permeate the organization [23]. Empirical models have been developed that study each of the sociotechnical system elements in relation to the effects upon the three organizational design dimensions of complexity (degree of differentiation and integration that exist within a work system's structure, formalization (degree of differentiation and integration that exist within a work system's structure.), and centralization (degree to which jobs within the work system are standardized. Centralizationwhere formal decision-making occurs within the work system [3,24].
Macroergonomics is concerned with the optimization of work system design through the consideration of relevant social, technical, and environmental variables and their inter-actions [22]. An important outcome of macroergonomics intervention is a culture change, where organizational culture is primarily defined as organization's core values, but which also includes traditions and unwritten rules [2,25]. Kleiner in Europe, there has been a strong tradition to investigate ergonomics problems within a holistic, systems context. ''Macroergonomics'' builds upon this tradition by providing specific methods and tools that yield large-scale results [20].

IDCs, the Ergonomists' work and their common outcome of the past activities in IDCs
It is noted about IDCs and the ergonomists' work that "Talking about ergonomics in relation to IDCs means that we have to define what is an IDC, not by economic criteria (e.g., GNP (Gross National Product)) but by population, prevailing forms of work and work ethic [26]. The case in point is studies of ergonomists who had conducted interventions in IDCs such as H. Shahnavaz, K. Kogi, H.W. Hendrick, PA Scott, A. Wisner and others was reviewed by Yeow and Sen [27]. On the other hand, the development and the need for ergonomics in IDCs is emphasized by Scott when Ergonomics can play a key role on assisting developing areas to break out of their negative poverty-driven spiral. Indeed, ergonomics can be a major factor in narrowing the gap between the "rich" and the "poor" nations of the world [11]. For this reason that, the working conditions in IDCs have been described by Shahnavaz, Scott, and Scott and Shahnavaz as 'suboptimal', 'physically demanding' and a 'complex array of problems' [28][29][30]. The lack of awareness about the potential benefits of ergonomics is the primary cause for underutilization of ergonomics principals. There is, however, no doubt that application of micro and macroergonomics is essential for improving working conditions, system efficiency and promotion of the quality of working life in IDCs [31].
One special and common outcome of the past activities in IDCs, regarding various types of ergonomics interventions and ergonomics awareness building in IDCs was the low involvement of ergonomists, the low degree of industry involvement, the short term impact of training and the low effect of training on the organization as a whole, mostly due to the fact that individuals have received the training and not the groups or organizations [7,8].
This is emphasized that for an ergonomics 'know-how' transfer management to IDCs' industries, need to a more challenging 'comprehensive plan and planning' with different ergonomics intervention techniques and its strategies with an intentional learning [7,8]. For this reason, there was a problem in focusing on problems because, deficit-phrased questions lead to deficit based conversation [32,33]. For example, according to Helali observed that it is mentioned as a definition of a problem in industries of IDCs like Iran, there are technical focus managers at work, a lack of interfaces between individual, group, and organizational levels at work, unsuitable work systems and unsuitable informal relationships within the organizations, and poor livelihood [33].
The main attention of ergonomists work in IDCs was on 'ergonomics awareness' (i.e., understanding without knowing) and working conditions when IDCs' industries need to further of here for ergonomics awakening (understanding with knowing) to purpose applying the ergonomics and human factors to work system in the organizations [8,33,34].

Necessity of the applying macroergonomics in IDCs' industries
Shahnavaz asserts that the advent of new technology, especially through technology transfer, imposes numerous health and safety problems on IDCs workplaces, which hampers the company's competitiveness [13]. However, the emphases for improvement limited to few progressive companies focuses on microergonomics which caused by traditional thinking, cultural issues and lack of knowledge and skill needed to deal with macroergonomics approach. Helali observed that it is insufficient for firms rely on only training, awareness creation, and ergonomics intervention when addressing safety, health, and ergonomics issues [7]. For this reason, Helali noted that both practical learning and reflection learning should be provided at all levels of the organization. Such provision could lead to the emergence of better organizational interventions, underlined by macroergonomics attitude in firms, when implementing systemic ergonomics intervention work at the workplaces [7,34].
The ergonomics intervention work in IDCs will be best achieved through macroergonomics input, which triggers with even no-cost/lowcost microergonomics improvements [7,34]. Productivity improvement is also a key issue in IDCs [7,12,13]. The success of no-cost/low-cost improvements actually depends on the careful selection of feasible solutions. Consequently, it is suggested that one should select, with the help of appropriate support tools, low-cost improvements that can be built into work methods and equipment and are realizable by means of local skills and materials [35][36][37]. Scott and Charteris emphasized that it is necessary to include both microergonomics (i.e., as a concept of an Ergonomics Stress Index (ESI) [38]), and macroergonomics approaches (i.e., the goal of it is to optimize the work system's design in sociotechnical system characteristics, and then carry the characteristics of the overall work system design down through to the design of individual jobs, human-machine and human-software interfaces to ensure a fully harmonized work system) [39]. Instead of evaluating the performance of two approaches, one needs to acknowledge their complementary interdependence, where the ratio between their inputs will vary according to the situation being addressed [39].
Hendrick and Kleiner noted, when the goal of macroergonomics is achieved, the result should be dramatic improvements in various aspects of organizational performance and effectiveness [3]. This has been shown in the results of ergonomics intervention work at Glucosan factories from 1995 to 1997 [40][41][42] and also three subsidiary companies in Iranian industries [43,44].
According to Hendrick and Kleiner, macroergonomics is top-down (i.e., strategic approach to analysis), bottom-up (i.e., participatory ergonomics) and middle-out approaches (i.e., focus on processes) [2,3]. Central to macroergonomics is the expectation that analysis and design of work systems will be participatory in nature [45][46][47]. To achieve human-centered work system designs, human-centered analytical processes must be used. This constitutes the sociotechnical principle of compatibility. Consistent with the emphasis on participation in a number of domains, participatory ergonomics is rapidly emerging as an area of international inquiry in its own right [48] and is seen as a core method in Macroergonomics. Macroergonomics is humancentered [16] and participatory ergonomics is a primary methodology of macroergonomics involving employee's at all organizational levels in the design process [49]. Therefore, it is emphasized that the concept of macroergonomics is human-centered and participatory [7,8].
Robertson noted, when a macroergonomics approach is taken, training is part of a comprehensive, systematic approach to enable knowledge within an organization [50]. But Deming describes a system as a network of interdependent components that work together to try to accomplish the aim of the system [51]. The system begins with an awakening ('an awakening to the crisis' as Deming described it) [52]. The aim of the awakening could be to stress the importance of the need to change. Without an awakening, the person can, at best, learn many important lessons. For example, Helali observed that different participants participated in the ergonomics training workshops between 1996 and 2002 from Iranian industries, or the ergonomics training workshops were conducted at group level for the Iran Khodro (Car) Company, between 2001 and 2002, or according to implementing "Job Enrichment" with using Ergonomic Checkpoints (ILO, new version 2010, [53]) at a Pharmaceutical Manufacturing Company in 2012 [54]. This resulted in participants learning many lessons. But, deeply motivated intention occurs after the awakening about using the 'Future Workshop' at the organizational level (Helali and Shahnavaz; Helali) [7,41] and also materialized though employing ILO's "Ergonomic Checkpoints" and appreciating the need for approaching understanding in the deep health, safety, and ergonomics, and the working condition as a whole research in the study of Dastranj and Helali; Helali and Dastranj [54,55].

The use macroergonomic intervention work in Iran
The ergonomics intervention thechnique models based on the long research journeys since 1996 by Helali's study could be focused on Ergonomics 'Know-How' (i.e., learning by doing could be characterized as practical knowledge), 'Know-What' (i.e., learning by using could be characterized as strategic understanding), 'Know-Why' (i.e., learning by studying could be characterized as theoretical understanding), 'Know-Who' (i.e., learning by engaging participants to purpose participation and collaboration) [33,34]. For this reason, the participants could be engaged in the recognition of processes and applying different ergonomics interventions-based on levels 'Training' (i.e., training as a learning-performance workshop), 'Learning' (i.e., learning by doing individually and collectively as the Ergonomics Intervention Programme Technique (EIPT) Process) and its 'Metareflection' (i.e., 'this is thinking again about our reflection-on-practice. It is stepping back and checking out what we thought and said earlier. It is further removed from the action than "reflection-on-practice" [7,56]. Accordingly, building 'taxonomy knowledge' on the ergonomics intervention work as a product joining up practice with theory could be outlined in Table 1 by Helali as follows [34]: The activities training and learning were based on using different technologies on the knowledge within organization. For this reason that, knowledge can be purposeful coordination of action. Achieving intended purpose is the sole proof or demonstration of knowledge [57]. Zeleny noted that its quality could be judged from the quality of the outcome (product) or even from the quality of the coordination (process) [57]. Helali has indicated that, ergonomics 'know-what' refers to the knowledge of objects, facts, components and goals from different strategic understanding as 'learning by using' because, Zeleny has noted "what is knowledge?" and also Sanchez has stated "what are three different kinds of knowledge within an organization [33,57,58]. Zeleny emphasized that pragmatic philosophical roots firmly established the knowledge when it was Albert Einstein who cautioned our world "Information is not knowledge" [57]. Thus Einstein also asserted "Knowledge is experience. Everything else is information" [57].
The first result of applying macroergonomics was at the Glucosan Factories between 1995 to 1997 in the manufacturing industries of Iran that it had a positive effect on their production capacity by applying macroergonomics intervention, i.e., a) in which the capacity rose from 70% to 105% of the nominal capacity; b) 'Utilization' of starch from corn was improved by 11%; c) Glucosan factories has achieved to the world best practices production level; d) The quality of the products was improved, reaching international standard, making it possible to be exported; e) An increase of up to 600% in all employee wages through profit sharing; f) Development of a new organizational system for making full use of worker participation; g) This practice was the first sample of applying ergonomics to work system in Iranian industries and was successful at the organizational level so that, after 12 months of macroergonomics intervention at Glucosan factories, the company's profit rose by 390% when there were also Organizational Development (OD) and a learning strategy at Glucosan Factories [7,42].
More than 19 years studies conducted by Helali on the ergonomics intervention work show the necessity of an awakening process and the applying ergonomics to work system in industries of IDCs such as Iran [34]. Consequently, developing vision, ideas and awakening at the organizations to apply ergonomics for improving the work system helps to achieve productivity in the workplaces [7,8,33].
The purpose of this study therefore was to create macroergonomics awareness and wakefulness at a Manufacturing Company, in order to emphasize the importance of improving "Working Conditions Systems" (Health, Safety, and Ergonomics) and understanding the necessity of the applying ergonomics to work system. It sought to develop vision, ideas and draw up checkpoints for the organization of work where research considers involving both of the company and the participation of participants, not only on people or techniques and tools.
This study was therefore underlined by the following question: "How cans a systemic pre-macroergonomics intervention work process, be introduced at the Manufacturing Company, in order to ensure the successful "Awakened need of change" to apply the ergonomics?" The company focuses on building up the capabilities of the hot section of gas turbine blades in various capacities, as the largest manufacturer of turbine blades used in thermal power plant in Iran is active. It had 738 employees (46 women and 692 men). Inclusion criteria for this study were: (i) Diploma or higher, and (ii) At least one year experience in the relevant units.

Procedure and Material
First research working organized through arranging four meetings (Separately for each member lasting one or two hours each) between the authors and the Heads of the Company's HSE (Health, Safety and environment) Department, Research and Development (R&D) Department, Human Resources and Logistics Department. Then a final meeting was held with all of them to present finding after conducting the study plan, which lasted up to 2011. Then, the manufacturing company approved the study and aimed to carry it during one year.
The survey approach was used from several steps with different sample participants: including; 1) Studying the three questionnaires which evaluated manager's viewpoint (29 people), health, safety and environment (HSE) employee's viewpoint (5 people), and operating worker's viewpoint (85 people), 2) Using Future Workshop (FW) for middle managers (15 participants), 3) Doing an ergonomics checklist in one of units of the company (29 participants), 4) Evaluating Workshop, with middle managers (15 participants), 5) Interviews with some participants in Future FW (10 participants), 6) Interviews with some participants in using of the checklist (4 participants) and, 7) Review of the organizational documents were used that this survey research describes detail it as follows:

Questionnaire Survey
First of all, three questionnaires on improving working conditions (three questionnaires for the managers, personnel of HSE department, and operational staff) designed by Chavalitsakulchai (1992; Appendices III to V) to evaluate improving working conditions programme in the industry were used to gather basic information about improvements in working conditions system in the company [62]. Each questionnaire followed a different approach.
In the Questionnaire Survey, the main and independent variable was Improving 'Working Conditions Systems' and the views expressed in the three groups and background variables such as demographic characteristics.
The sampling method used for managers and HSE staff was the census sample method, and the method used for operational employees (Population of 270) was the Cochrane (Correlation coefficient 0.3) approach.
To analyze the questionnaires, the primary relation between Chisquare, Pearson, Kruskal Wallis and Mann-Whitney tests were used.

First Workshop (Future Workshop with introducing Macroergonomics)
Future workshop (FW) based on the Müllert and Jungk (1987) model, has 5 phases, with phases 2, 3, and 4 forming the main parts of the FW [63]. According to , the five phases are defined as follows: 1) Preparation phase (i.e. the aim of this phase is to define a clear, short and challenging 'theme' for the workshop, acceptable to all participants) [41].
2) Experience phase: Also called 'critic phase' (i.e. this phase aimed to highlight all problems experienced by participants with regards to the workshop's theme. A complete 'problem catalogue' is developed).
3) Fantasy phase (i.e. the aim of this phase is to come out of the daily limitations that usually lead to restraint, traditional thinking and acting. Participants have many ideas that have never been expressed or formulated because they are framed in what they believe is right and possible. In the fantasy phase, everything is possible. There are no barriers, no economic, personal, technical or organizational limitations. The idea is to develop future visions). This method has also been used in IDCs as an ergonomics tool in studies carried out by, ; Sanda (2006);  and Helali (2008;) and also see Sanda et al, (2011) the using it further of here as a tool in problem-indentification workshop [7,8,41,44,64,65].
The FW was announced through an invitation sent by the training department to all Top and Midlevel Managers of the company, and was held for two days at the conference hall of the company. It was attended by the mid-managers and individuals from different departments of the organization. At the beginning of the FW, some discussions were presented about the necessity of knowing about macroergonomics and participatory ergonomics as its tools in order to provide a correct understanding of the working conditions improvement system and the removal of obstacles as well as developing a working conditions improvement system.
In the first phase of the FW, developing organizational behavior was the first factor contributing to a working conditions improvement system using the macroergonomics approach. Therefore, the FW focused on developing Organizational Behavior (OB). Once the participants agreed with this topic, and the FW would be entered phases 2, 3 and 4.

Applying an Ergonomics Checklist on some 'Department'
A checklist of ergonomics issues presented by the International Labor Office (ILO) and the International Ergonomics Association (IEA) (ILO, 1996 [60]) was used to continue the analysis using the macroergonomics approach after a manager with one of units of the company taking part in the FW showed interest in this regard. This first version of the book's translated was published to Farsi by Gclocosan Factories in 1996.
It is comprised of a checklist, checkpoints on 9 different topics and important principles related to safety, health and ergonomics, including materials storage and handling (21 checkpoints), hand tools (15 checkpoints), machine safety (20 checkpoints), improving workstation design (14 checkpoints), lighting (9 checkpoints), premises (6 checkpoints), environmental hazardous (7 checkpoints), welfare facilities (13 checkpoints), and work organization (23 checkpoints). The ILO book (version 1996) was used and this was done in a production unit of the company, which had 29 employees, including the chairman, supervisors and operational staff (used census sample method). Seven action groups were formed to implement the checklist: In each action group, the organization of work was assigned to supervisors and heads of departments while other tasks were given to ordinary employees. Learning from each other and sharing their experiences in the workplace, the taskforces examined the ergonomics checklists 2 months after they were implemented, and represented their solutions for problems existing in their workplace. Finally, the feasibility and application of all the solutions were evaluated in the presence of all the participants. As well as to assess the ergonomics condition based on the participants' answer to checklist, the ELMERI index was used [67].

Second Workshop (Evaluation Workshop)
Almost five months after using the FW technique, the premacroergonomics intervention situation was evaluated at a workshop attended by the participants. The evaluation covered the following question: "after this period of time, what do you think about the existing or future working condition improvement systems as well as the optimization of such systems?" Meanwhile, the company's training department evaluated the effectiveness of the FW independently, determining the level of macroergonomics based on the viewpoint of 15 participants (who had participated voluntarily).

Interview with the participants of the First Workshop
This interview aimed to explore and understand ideas of people as a reflection about Improving 'Working Conditions System' problems after participating in the FW. After explaining the purpose of the interview participants, they voluntarily participated in the interviews (10 participants).
In this stage, the participants were interviewed based on a semistructural basis (they were asked questions such as "since you have taken part in the FW, how do you evaluate the problems existing in your own company?), in order to better understand the depth of problems with the company's working conditions improvement system. To analyze the results of the interviews, analytical interpretation methods were used.
were classified under three topics related to the organizational and corporate culture of the company, these topics included: -Systems, methods and organization (17 items); -Human resources (Cultural, educational) (13 items); -Business development, strategy and planning (3 items).
After selecting items for the three above individuals based on their interest and expertise in organizational units, three groups were formed with the above titles for the implementation phase of the fantasy. 33 prioritized problems classified in the experimental phase and moved to the fantasy and strategy phases so as to adopt proper solutions for the problems.
The 33 problems were scored and classified into three groups, including the systems, methods and organization group, human resources group and business development, strategy and planning group. After initial examinations, the groups represented the 4 main problems in the fantasy phase. Finally, solutions offered for the problems, were examined by the three working groups in the strategy phase. Lack of accountability system and lack of collaborative leadership styles were the two fundamental problems related to organizational behaviour and working condition improvement system discussed by the first group. Regarding the lack of accountability in the company, some mid-level managers stated that unaccountability on the part of different departments contribute to the lower quality of the overall performance of the work system. The second problem (lack of collaborative leadership styles) leads to the failure to use the full capabilities of individuals to improve working conditions.
The second group studied the problem of profit-orientation, which could not be blamed on individuals. This problem is due to the lack of workable systems for improving working conditions, according to the questionnaires and the viewpoints of those taking part in the FW.
The third group examined the problems of the sudden growth of the organization and waste of resources. These problems were represented as important problems ahead of the work system of the company related to improving working conditions, according to interviews with the participants after the workshop.
Results related to the effectiveness of the FW were also studied by the Training Department of the Company, with the effectiveness standing at 78%. After the second day of the workshop, the participants were asked to offer their opinion about being in the process and their understanding of it. The main viewpoints offered by the participants included: 1) To sort out the problems and the related departments; 2) To get better viewpoints on macroergonomics; 3) To learn more about the interaction between individuals and departments; 4) To determine the synergy effects of macroergonomics; 5) To become prospective and identify methods for creating cooperation between managers and employees to solve problems and make better decisions; 6) To secure

Interview with those participating in applying the checklist
After of 2 months from applying the checklist, 4 participants were interviewed on a semi-structural basis (they were asked questions such as "how the application of the checklist to all levels of your organization affected efforts to identify problems with its working condition improvement system?"; "Having applied the checklist to all organizational levels, what do you think is wrong with your company's working conditions improvement system?"; "How did the utilized approach affect you and your organization? After of interview, for analyze the results, analytical interpretation methods were used.

Review of the organizational documents
In this stage, monthly and annual reports on HSE department, along with the personnel records of the employees belonging to 2009 and 2010 were surveyed.

Results of the Questionnaire Survey
The Demographic and organizational characteristics of questionnaire study population has shown in Table 2.
Based on Table 2, almost of participants were men in the middle managers and the HSE department personnel (respectively 96.6% and 80%). Also the operational staffs of the study population, 100% of the sample were men.
A statistical analysis of the data revealed that the three questionnaires had covered 119 people of the three groups presented in Table 3.
The results of the questionnaire indicate that the three groups taking part in this study had similar ideas on some issues with regard to the working conditions improvement system, and there were no significant differences between them, and there were significant differences between them on some other issues. It is important that the three groups have pledged to participate in efforts to promote the existing working condition improvement system presented in Table 3.

The Results of the Future Workshop
FW conducted for middle managers 15 participants that Table 4 has shown demographic and organizational characteristics of participants in the FW.
Based on Table 4, the middle managers of the subjects, 86.7% of males and 13.3% were women. The mean age and Job Tenure of participants in FW was, respectively 34 and 3.4 years. Also, many participants (80%) were bachelor level education.
In the FW, in the first phase, which was the preparation phase, the participants mentioned the problem related to organizational behaviour as the most important problem ahead of the working condition improvement system. A total of 83 problems were mentioned by the participants in the experimental phase. Having prioritized the stated problems, the results  brainstorming in identifying and solving work problems; 7) To cause fundamental shifts in thinking about the concept of ergonomics; 8) To find ways to create interaction between employees and work systems; 9) To determine the impacts of any failure in part of the system on the whole work system; 10) To study macroergonomics in relation to human interactions with the systems; 11) To determine different tasks in solving work problems; and 12) To understand of micro-and macroergonomics comprehensively.

Results related to applying the checklist to some departments
The demographic and organizational characteristic of participants in using the checklist has shown in Table 5.
Results related to the application of ILO ergonomics principles checklist to one department of the company by the 7 action groups have showed that out of the 128 questions on the checklist (ILO [60]), 68 questions pointed to problematic issues and 60 questions referred to desirable issues. The ergonomics conditions for problematic working environments were mentioned in category 3 of the checklist selection guide (Laitinen et al.,) based on the ELMERI index, the issue needs to be explored and solutions for improving the situation should be developed in the future in addition to focusing on the priorities. It should be noted that, with regard to the ergonomics problems observed in the department, 47 ergonomics solutions to improve working conditions were presented by the action groups (Figures 1 and 2).   Based on the Figure 2, diameter and pinch point of Hand tools redesigned for operators' health and performance. The main ergonomics solutions that offered by the action groups are presented in Table 6.

The results of the evaluation workshop
In this evaluation workshop, the participants expressed the company's main problem in operating systems and the lack of appropriate interaction between different departments of the company as well as the lack of proper work systems, which have led to a lot of problems (such as delays in implementing solutions to improve working conditions, poor cooperation between different departments in implementing the solutions, and the lack of such interaction), and noted that these problems result in the lack of proper solutions to improve working conditions.
In addition, the head of the related department who voluntarily allowed the implementation of the ergonomics checklist in his department, has presented results concerning the implementation of the ergonomics checklist in a report on the evaluation of the FW's effectiveness and offered relevant evidences presented by the action groups within two working months, emphasizing 47 ergonomics solutions due to their usefulness both in micro and macroergonomics levels, as well as their differentiation and positive organizational interaction ( Table 6).
The survey of this workshop showed that participants emphasize and confirm the effectiveness the cases of the result of the learning by using of the FW again after five months.

Results related to interviews with the participants of the future workshop
Results related to interviews with mid-level managers participating in the FW are presented in Table 7. The interviews were conducted five months after the FW.

The results of interviews with those participating in applying the checklist
The results of interviews with participants involved in applying the checklist of Ergonomics Checkpoints (ILO [60]) are presented and interpretation on requirements them in Table 8.

Results related to the review of the organizational documents
Records of absence from work, taken from organizational documents, and the prevalence rate of musculoskeletal disorders among the workers are seen in Figure 3. Based on Figure 3, most of the employees were suffering from low back and knee problems. The poor postures of workers in the production line are indicative of the poor performance of the company's working condition improvement system (Health, safety, and Ergonomics). The percentage of each musculoskeletal problem that made employees quit their job last year is as follows: neck (13%), shoulder (7.4%), elbow (0%), upper back (3.7%), low back (38.9%), wrist/hand (5.6%), hip/tight (5.6%), knee (11%), ankle (7.4%), feet (7.4%).
Furthermore, the workers were absent from work for 1819 days due to occupational diseases in 2010, up 36.5% compared to the 1333 days in 2009.

Discussion
The results and relevant interpretation are discussed from the perspectives of the following 'the definition of a phase method systemic pre-macroergonomic intervention work for 'awakened need of change'", "A model on getting the different levels of learning", and "its meta-reflection on" as follows: As it is shown in Figure 4, a frame has been designed to define the systemic pre-macroergonomics intervention work process prior to using different macroergonomics methods on the learning levels. This is a concept of empowerment as process [62][63][64][65][66][67][68]. Based on the empirical evidences from this study, integrating the aforementioned factors coupled with the creation of a team of facilitators (the authors were the internal and external facilitators), resulted in the purpose of this study for the awakened need to change to apply ergonomics to work system. The key findings were made through intentional learning on how the middle managers with the macroergonomics attitudes as 'Top-down' (i.e., strategic approaches to analysis from the three questionnaires survey), 'Middle-out' (i.e., focus on the process of using FW) and 'Bottom-up' (i.e., participatory ergonomics of using the ergonomic checkpoints), the participants could be empowered in the different cycles of learning, based on the interactive approach used the systemic pre-macroergonomics intervention work.      The findings in this study are signified by PDSA Cycles of learning introduced by Deming [51]. Accordingly, the notion of open system theory has played a crucial role in the study of organizations; for example, the sociotechnical theory is heavily influenced by the systems theory. It is usually also referred as macroergonomics [3]. Action however, must be managed by different learning levels ( Figure 5), this could be accomplished through a Plan-Do-Study-Act (PDSA) cycle [51]; i.e., the PDSA cycle describes a method of continuous improvement. First, the problem is identified and a subsequent solution is found (Plan). Then the solution is applied with the hope that it eliminates the problem (Do). After this, the result of the activities is investigated (Study). The last phase is to establish the result in the organization to see if the result is satisfactory, and gives feedback to other interested parties (Act). This cycle is a flow diagram for learning, as well as for improvement of a product or of a process. Additionally, learning must be continual. The only way to continue the transformation is to obtain feedback and to reflect [69], and then to repeat the loop to different purpose learning levels ( Figure 5) with a "Meta-Reflection" when we will go further of here as an "empowerment as a way of thinking" [33,59,68].
Therefore, based on the design of this kind of work by the second author, a study has been implemented in one of Iranian industries in 2010 by the authors as a successful interactive research work [59,70].
The model could be characterized based on understanding the organizational knowledge on the systemic pre-macroergonomics intervention work at the company with the different getting learning understanding when there are the different concepts of "learning" and its meta-reflection in Figure 5 as follows: The first cycle of the research survey on the organizational knowledge was 'know-why' as theoretical understanding or learning by studying for the awakened need of change. For this reason, we were used the three different questionnaires survey to managers, HSE (Health, Safety, and Environment) department personnel and operational staff that it could be used to gather basic information about the improving working condition system status of each company from three views of organizational levels. This could show us one kind of empowerment as a way of thinking on the company when we use example Chavalitsakulchai's questionnaires that it was designed in 1992 and we could apply and analyze statistically it to propose where company is standing for improving working condition system as follows: All the three groups (managers, HSE department personnel, and operational staff) have realized the importance of improving working conditions (health, safety and ergonomics).
Improving working conditions and offering solutions for health, safety, and ergonomics problems were the main goal behind developing the working conditions improvement program. According to the results of the Chi-square and Kruskal Wallis correlation test, there was no significant difference between the viewpoints of the three groups.

Inappropriate interaction among the departments It means that there is poor interaction among the departments and that customers are not respected su ciently Task & people level: Sociotechnical approach which both technical and human-centered approaches are Acknowledged and merged together in the social & technical approach.

Abnormal and unplanned development is the main reason behind all the problems existing in the company This means that, the staff always has high levels of stress at work, because they are not ready and are not aligned with the requirements; and do not have the potential to make changes and move toward development. As a result, they are e posed to insta ility and loss o o . rgani ational documents indicate hiring young staff is the best solution to the problem, but loss of nancial and human resources ere still one o the main concerns o the director in the initial meeting. He stated: "we are losing our skilled workforce and that is problematic. So we need the ergonomics.
Management & Leadership contributes to making changes (applying Macroergonomics)

There is no workable system in the company. Variable methods such as EFQM, ISO 14000, and OHSAS18001 and 5s are used of course, but the system is not comprehensive and the methods have not been implemented correctly and fully. So there are some problems in the company such as insu cient cooperation on the part o department staff This means that the lack of staff involvement and cooperation in implementing these systems is one o the main reasons ehind using fla ed methods.
Usually, training is provided to individuals regardless of their duties. Due to such negligence, problems such as the lack of interactions between the enterprise and the staff, lack of practical learning and failure to localize the methods are observed Participatory Ergonomics and Practitioners' commitment toward working with people ethically 6 oor planning due to poor o descriptions hich do not de ne the duties and responsi ilities clearly This means that work expectations are not clear, especially with regard to mid-level managers, employees are confused and suffer from stress, something that interfere with the progress of work, organizational commitment and motivation.
or systems should e modi ed 7 Lack of proper planning at the macro level and lack of relevant details, as well as lack of proper information on the annual programs of the departments. As a result, programs are not implemented properly and expectations are not met This means that the process of work in the company has not been organized and does not respond in a dynamic way Ideas or actions, including middleout (i.e., focus on processes), top-down (i.e., strategic approach to analysis), and bottom-up (i.e. participatory ergonomics.

The organization is facing many problems due to the independence of work systems, doing o s in cross-sectional ays and lac o proper communication between the departments Means parallel work, waste of resources, and so on Commitment to learning and change 9 Poor cooperation causes low participation in both higher and lower levels. In case of participation, it will be due to pressure (sectional) exerted by the management or due to non-formal relations among some individuals in some departments It means that the manager should direct informal relationships toward workrelated relations, so that a formal organization acceptable by the staff will be designed and implemented This also requires proper macroergonomics intervention programs

10
Employee commitment and motivation decline day by day due to paying little attention to the lower staff, particularly operators and technicians, and paying too much attention to mid-level managers and directors who are rewarded with bonuses.
It means that there is little commitment toward learning, organizing and making positive changes Using participatory ergonomics in the company is necessary Table 7: Results related to interviews with mid-level managers and relevant interpretations.
It is noteworthy that, according to the viewpoints of the three groups, group solidarity does not play an important role in improving working conditions, something that is regarded as a weakness. Hendrick stated that interactions among different departments would be improved if the macroergonomics approach used beside the human-machine and human-software interactions at the micro level [15]. This conclusion is clearly evident in the results of studies on Glucosan Factories by Helali and Shahnavaz, and the results of studies on the Iranian industries by Helali et al.; Helali and also Shahnavaz et al. [42][43][44]71].
Based on the viewpoints of the personnel of the HSE department, their working goals contribute to improving working conditions in the company.
Preservation and maintenance of labour at each working environment is the most important objective of the HSE department (Table 3).
According to viewpoints the managers and HSE staff, the top management is responsible for setting goals for the working conditions improvement program. The employees believe that the supervisor of the HSE department should be assigned to do this job. The results show that the three groups taking part in the study had no idea who was responsible for the aforementioned task ( Table 3). As for the macroergonomics concept [2,3], the interaction must be a two-way or multi-way one, so that it could lead to synergistic cooperation and better results.  Better interaction was observed among the staff, supervisors and mid-level managers with regard to offering innovative and creative ways to identify problems and provide appropriate solutions after the taskforces became cooperative.
It means that better interactions were observed among different levels of the organization with regard to identifying problems after they all were involved in the process. Previously, there was no such interaction in the company with regard to using appropriate ergonomics tools.
Macroergonomics approach should be used in the company in order to involve all levels in ergonomics interventions

Involving all levels of the organization in the process of identifying problems and providing convenient and inexpensive solutions to improve the working conditions of the departments led to a better interaction between different departments of the company.
It means that it will lead to better interaction among different departments in identifying and solving problems The Macroergonomics approach, especially the participatory ergonomics, should be employed in the company in order to improve work systems

4
The employees were motivated to Identify problems and offer solutions so as to make managers realize the important role of the employees in improving working conditions.
It means that the employees should interact with each other using all potentials of the different levels of the organization in order to show their creativity and innovation.
Using participatory ergonomics is necessar Based on the viewpoint of the management, the personnel of the HSE department, the manager and supervisor of each department should be in charge of setting goals for the working conditions development program. The personnel of the HSE department believed that this responsibility should go to the safety committee. The results show a significant difference between the three groups in this regard. As for the results of the Chi-square correlation test, the three groups attach little importance to the role of inter-group interaction in identifying problems related to the working conditions improvement program ( Table 3). Interviews with the operational workers showed that they were more motivated to cooperate in identifying problems because they believe they face with the problems and can better help identify them. According to the policies of the company's working conditions improvement program, the employees are of little importance. Imada has noted that employee participation plays a major role in improving working conditions [72].
According to the management, the personnel of the HSE department and the safety committee are in charge of the working conditions improvement program. The personnel of the HSE department believed that this responsibility should go to the manager of each department and the personnel of the HSE department. The workers believed that such a responsibility should go to the workers. Regarding the results of the Chi-square correlation test, there was a significant difference between the managers and workers in this regard. Based on the Kruskal-Wallis and Man-Whitney tests, there was a significant difference between the average answers provided by the two groups of managers and employees. The managers and the HSE department personnel believed that the workers plays little role in presenting solutions to improve working conditions, because they themselves are to blame for the related problems. It is noteworthy that the three groups attached little importance to the role of interaction among themselves in improving working conditions, something that could be blamed on the lack of proper working systems (Table  3). On the other hand, the literature of macroergonomics shows that all available resources in the organization should be used in order to increase the accuracy of the measurements and contribute to employee motivation and commitment [3].
The three groups emphasized the role of the manager of each department and the personnel of the HSE department in improving working conditions. According to the Kruskal-Wallis and Man Whitney tests, the average answers provided by the managers, workers, and the personnel of the HSE department showed a significant difference between the three groups. It indicates that there has been little interaction among these groups (Table 3).
In addition, enhancing knowledge to identify problems is an important factor that contributes to improving working conditions, according to the three groups. It indicates the need for extraorganizational scientific support to improve working conditions. Also, the three groups believed that support from the top manager also contributes to the success of the working conditions improvement program.
Regarding the results of the Chi-square correlation test, there was no significant difference between the three groups in terms of ideas, but there was as significant difference between them with regard to the use of better interactive methods.
According to this study, lack of a proper work system in the company under study has led to problems such as insufficient cooperation among different levels of the organization, independent performance of different departments, poor interactions among the departments, lack of a constant working conditions improvement program, and slow improvements and reforms.
Tables 7 and 8 imply that the organization of work in the company is not appropriate and should be revised. They also show the importance of organizational planning and correct management coupled with cooperation among all levels of the organization. The need for using macroergonomics and making suitable interventions in the company are the other things that could be construed from the above-mentioned tables.
The second cycles of the research survey on the organizational knowledge was 'know-what' as strategic understanding or learning by using for the awakened need of change. For this reason, there are three kinds of the strategic understanding for building ergonomics intervention techniques that were noted by the Helali's study in 2012 [33]. However, there are two different research questions here: 1) How can vision and ideas be developed for applying ergonomics to work system in the company with a middle-out macroergonomics intervention; and 2) What are new checkpoints of work organizations. This could show us one kind of empowerment as a process. Consequently, we could use Future Workshop (FW) based on the Müllert and Jungk model [63]. Before that, it has been used and tested as an ergonomics tool in the IDC since 1996 as mentioned [41]. Here the focus is on the second learning cycles (Figure 4) that all middlemangers of the company must be participated in FW. Because of turnover the change of top managers is high in the IDC's industries. However, the middle-managers have more support role implementing each positive plan and planning.
For this reason, Hendrick and Kleiner noted that Middle-out, an analysis of subsystems and work process can be assessed both up and down the hierarchy from intermediate levels, and changes are made to ensure a harmonized work system design [3].
Awakened need of change has shown that the awakening will be motivated by dissatisfaction with the current state and/or the vision of the future state should the current approach to management and leadership remain [69]. The aim of the awakening is planning for change was the most important issue indicating dissatisfaction with the present state and articulating a desired future. The planning process involved participants from all levels of the organization rather than relying on a single entity or group [51].
According to the findings, the participants showed a kind of awakened need of change after attending the FW and presenting feedback for the learning of each other after five months. It also should be noted that two of the midlevel managers who took part in the FW have changed their approach to the participatory ergonomics approach, which means the involvement of the staff and interactions in the department. Also, the results of the questionnaires, the FW, and applying of the checklist show that all personnel of the company from all levels are not involved in the working condition improvement system, something that led to more absence from work due to occupational and musculoskeletal disorders during the two-year period covered by the study. It also led to doing tasks slowly and little cooperation among different levels of the organization with regard to improving working conditions. To solve these problems, it is necessary to apply changes to the working condition improvement system and review ergonomics. These points could be taken into consideration by Top Managers understanding and also, using the participatory ergonomics intervention method. The participants in the FW (middle managers) emphasized the fact that the desire for change process should also be observed among the top management, so that the organization could implement the proper intervention process for improving the working conditions through the top management's full support. It should be noted that the continuation of the process requires full implementation of macroergonomics intervention such as the ergonomics intervention program technique process model employed by Helali's [7], which emphasizes the importance of practical learning and full realization of macroergonomics attitudes toward applying ergonomics to the work system [2,3].
The third cycles of the research survey on the organizational knowledge was 'know-how' as practical understanding or learning by doing, for the awakened need of change. Accordingly, there are different doing of ergonomics intervention techniques that Helali has shown that how step by step an ergonomics intervention technique and its developing could be formed and studied in an IDC [7,8,34]. In this process, one of the main contributions of the participatory ergonomics process was, using the ergonomic checkpoints [7,53,60,73]. For this reason, the using ILO's book which is based on an action learning or participant engagement by doing helps participants to see integrating "Health, Safety, and Ergonomics" at the workplace as well as one kind of job enrichment based on ergonomics principles and finding new checkpoints. In this study, the ergonomics problems observed in the department, 47 ergonomics solutions to improve working conditions were presented by the action groups. For this reason that, the actionchecklist of the ergonomic checkpoints helped to organization that the participants discuss and use it in some divisions till they see and take a whole picture of health, safety, and ergonomics problems in the workplace as one kind of collective empowerment [43,54].
Following this study, the participants took part in the systemic pre-macroergonomics intervention based on the Figures 4 and 5, so as to better understand the work system and macroergonomics reach the awakened need of change stage. In this way, full support of the top manager is necessary in implementing ergonomics 'know-how' transfer management to enhance human working for sustainable improvements in the industry sector of IDCs such as Iran [33].
A Meta-reflection; this research could be in an 'appreciative way', i.e., research with company and the participation of the participants, not only on people or techniques and tools. For this reason, this could be 'empowerment through reflection', i.e., "empowerment as a process", "Empowerment as a discourse", "empowerment as a way of thinking", and also "collective empowerment" for the awakened need of change to apply ergonomics to work system [68].
The practical applications and implications of the systemic premacroergonomics intervention are drawn from the finding of the framing positive question. The appreciative reflection is a new form of reflection and it has shown four basic types of appreciative intent toward, knowing, relating, action, and organizing [33,74]. This is one kind of appreciative work system or an appreciative systemic macroergonomics work completely when the purpose could be empowerment through reflection on the awakened need of change to apply ergonomics to work system further of here and, its metareflection as "maximizing strategy" (recognizing when an amplification of the 'success' is necessary; including, appreciative inquiries and root cause of success). This can be concluded as follows: • Knowing: What could be the successful of this kind of systemic pre-macroergonomics intervention right now? (Appreciative): Some inquiries and concepts in an action pathway ergonomics intervention journey in the IDC and this paper for knowing are significant now: "What will the awakened need of change be we want more of here?" (i.e., Appreciative innovating) and "How can we amplify this? As well as how does the future unfold an appreciation of the positive present?" (i.e., reflection learning and action), or "How will we go further here?" (i.e., leading through appreciative). Therefore, this noted that appreciative inquiry and appreciative intelligence are considering something that is looking towards a better future, not necessarily what is wrong [7,33].
• Relating: What did we need to change to make a better future? (Imagine): Based on the Work System Sub-Systems study, Figure 6 can be a conceptual model of "Awakened Need of Change" for an Appreciative Work System. This is also indicated as the key characteristic of the sociotechnical system components identified by Kleiner [75].
• Action: How did we do this? (Design): This is toward a kind of ergonomics intervention-type action research or reflection learning and action [7,33,76], for this reason, totally, it is mentioned that Participatory and Appreciative Action Research (PAAR) are the third kind of action research about: 1) Using the power of the positive question; 2) Amplifying the core positive question not 'problem solving'; 3) Leading by valuing, not evaluating; 4) 'Appreciative Intelligence' (multiple intelligence); i.e., the ability to see the mighty oak in the acorn, and look at all successful things; 5) 're-framing' (i.e., how one can amplify those things that will help a better future emerging from positive present) by choice not one and best way for doing, or seeing how the future unfolds the present [76,77]. This can be with focus on the following sub-research questions that it can be formulated as "What are your workplace stories", "journeys", "cultures" and "ballets (i.e., dances)" about applying ergonomics to work system and how you want to amplify it?
• Organizing: Who took action and with what consequences? (Act): In the appreciative way, the role of people/participants are to engage in the appreciate path to ask and reply to the
