    The impact of ERP partnership formation regulations on the failure of ERP implementations2013In: Procedia Technology - Elsevier, ISSN 2212-0173, E-ISSN 2212-0173, Vol. 9, p. 527-535Article in journal (Refereed)
    Abstract [en]

    According to statistics, majority of ERP implementations fail. Failure means either total cancellation of the project, or failure to go-live on time and/or within budget constraints. Mainstream literature focuses on different reasons for failure including poor project management, resistance to change, lack of top management support, insufficient user training, etc. In this research we focus on the impact of vendor-partner relationship on the failure of ERP implementations. Some vendors provide easy terms and conditions in order to attract new partners and develop a wider network of partners in the targeted regions. In this study, the terms and conditions of SAP for certifying partners are studies and analyzed. In addition, case studies of two SAP partners are conducted. The primary research results suggest that the easy partnership conditions set by ERP vendors are among the main contributing factors for ERP projects failure in our cases. This finding is considered novel since most of the related work attributes failures to other factors, ignoring the vendor-partner terms and conditions.

    Abstract [en]

    This literature review paper summarizes the state-of-the-art research on big data analytics. Due to massive amount of data exchanged everyday and the increased need for better data-based decision, businesses nowadays are looking for ways to efficiently manage, and optimize these huge datasets. Moreover, because of globalization, partnerships, value networks, emergence of social networks, and the huge information flow across and within enterprises, more and more businesses are interested in utilizing big data analytics. The main focus of this paper is to elucidate knowledge on the characteristics of big data analytics literature as well as explore the areas that lack sufficient research within the big data analytics domain, suggest future research avenues, as well as, present the current research findings that could aid practitioners, researchers, and vendors when embarking on big data analytics projects. Towards that end, we have reviewed 24 publications between 2010 and 2014. Results of text mining the papers revealed that they belong to three clusters with both common as well as distinct characteristics. The reviewed papers were clustered into three main themes, 1) technical algorithsms; 2) processing, cloud computing, opportunities & challenges; and 3) performance, prediction, and distributed systems.

    The Future of ERP Systems: look backward before moving forward2012In: Procedia Technology - Elsevier, ISSN 2212-0173, E-ISSN 2212-0173, Vol. 5, p. 21-30Article in journal (Refereed)
    Abstract [en]

    This paper explores the enterprise resource planning (ERP) systems literature in an attempt to elucidate knowledge to help us see the future of ERP systems' research. The main purpose of this research is to study the development of ERP systems and other related areas in order to reach the constructs of mainstream literature. The analysis of literature has helped us to reach the key constructs of an as-is scenario, those are: history and development of ERP systems, the implementation life cycle, critical success factors and project management, and benefits and costs. However, the to-be scenario calls for more up-to-date research constructs of ERP systems integrating the following constructs: social networks, cloud computing, enterprise 2.0, and decision 2.0. In the end, the conclusion section will establish the link between the as-is and to-be scenarios opening the door for more novel ERP research areas

    Abstract [en]

    This paper is an effort towards illustrating the use of expert panel (EP) as a mean of eliciting knowledge from a group of enterprise resource planning (ERP) experts as an exploratory research. The development of a cost estimation model (CEM) for ERP adoptions is very crucial for research and practice, and that was the main reason behind the willingness of experts to participate in this research. The use of EP was very beneficial as it involved various data collection and visualisation techniques, as well as data validation and confirmation. Beside its advantages, one of the main motives for using a group technique is that it is difficult to find a representative sample for a casual survey method, as ERP experts and consultants are rare to find, especially in the scope of SMEs' ERP implementations. It is worth noting that the panel reached consensus regarding the results of the EP. The experts modified and enhanced the initial cost drivers (CD) list largely, as they added, modified, merged and split different costs drivers. In addition, the experts added CF (sub-factors) that could influence or affect each cost driver. Moreover, they ranked the CD according to their weight on total costs. All of this helped the authors to better understand relationships among various CF

    ERP adoption cost factors in SMEs2011In: Proceedings of the European, Mediterranean and Middle Eastern Conference on Information Systems: Informing Responsible Management: Sustainability in Emerging Economies, EMCIS 2011 / [ed] Ahmad Ghuneim; Marinos Themistocleous; Dimitrios N. Koufopoulos; Muhammad Kamal, Information Systems Evaluation and Integration Group, 2011, p. 130-141Conference paper (Refereed)
    Abstract [en]

    Small and medium enterprises (SMEs) have limited budgets, resources, and great sensitivity to costs. When SMEs take the first step into implementing an enterprise resource planning (ERP) system, they need to think about many things, foremost the cost of adoption. Most ERP implementations fail due to inaccurate and optimistic budget and schedule estimations, as well as, anticipating indirect costs beforehand is problematic. With the deficiency of a clear model of cost factors for ERP adoptions, ERP adoptions face a high risk of failure Failures could be caused by several factors, but the scope of this research is focused on studying the factors that escalate costs. This could aid SMEs in visualizing the different expected costs, and would consequently assist in better future cost management and estimations. There has been plenty of research in ERP; however, a clear gap in ERP cost management and estimation exists. This paper focuses on identifying direct and indirect cost factors that influence total costs in the ERP adoption process. The paper presents a cost list that has been developed through literature and an ERP expert panel. Furthermore, this study validated the costs list through interviews with different stakeholders within ERP adoption projects in Egypt.

    ERP Selection: A Case of a Multinational Enterprise2016In: Information Resources Management Journal, ISSN 1040-1628, E-ISSN 1533-7979Article in journal (Refereed)
    Abstract [en]

    "The system and vendor selection are early phases in the Enterprise resource planning (ERP)""implementation process. When organizations embark on selecting an ERP system, they develop their own selection criteria that usually involve various factors like number of modules, required budget, licensing model, etc. One of the paramount factors is the system’s fit with the organizational requirements and needs. Thus, the selection phase is a crucial endeavour, because if an organization chooses an inadequate ERP that doesn’t accommodate their needs, the whole adoption project will most likely predestine to fail. This research provides an overview of an ERP selection process at a subsidiary of a multinational company. The paper provides details about the selection process, criteria, and the evaluation process made by an ERP selection consultant that has been hired by the company to assist them during this phase. The selection process employed a simple multi-attribute rating technique (SMART) ERP selection method. In addition, this research presents other issues that influenced the selection process, which are related to cross-border data protection laws between the holding company and its subsidiary. As the ERP has been implemented successfully, the method and the selection factors have been proven adequate for the selection process.

    ERP Selection: The SMART Way2014In: Procedia Technology - Elsevier, ISSN 2212-0173, E-ISSN 2212-0173, Vol. 16, p. 394-403Article in journal (Refereed)
    Abstract [en]

    Enterprise resource planning (ERP) systems implementation projects are challenging and resource consuming. There are several phases in the ERP implementation process. One of the earliest and most critical phases is the ERP selection phase. If an organization selects an inadequate ERP to fit their needs, the project will most likely destine to fail. Research and practice have provided several cases of ERP project failures because of a faulty selection process. No matter what amendments the adopting company undertakes in the later phases, if there is no fit, there is no success. This research, presents an explanatory case study, which employed a simple multi-attribute rating technique (SMART)-based ERP selection method. The selection method was mainly based on developing process maps for all the critical business processes inside the organization, and then checking the degree of compliance of the potential ERP packages with those developed process maps. In addition, other factors were also included in the ERP evaluation and selection process. As the ERP was assured to be matching the business requirements, the method and the selection factors have been proven adequate for the selection process. In addition, this minimizes the risk of a non-fitting ERP system and consequent project failures.

    ERP adoption cost factors identification and classification: a study in SMEs2013In: International journal of information systems and project management, ISSN 2182-7796, E-ISSN 2182-7788, Vol. 1, no 2, p. 5-21Article in journal (Refereed)
    Abstract [en]

    Enterprise resource planning (ERP) systems adoptions require substantial resources and investments. The majority of businesses around the globe can be considered to be small and medium sized enterprises (SMEs). Thus, SMEs are seen to be typical companies that are the cornerstone of most economies. Compared with large enterprises, an SME-context contains several characteristics, and scarcity of resources is among the top of them. For SMEs, unplanned costs escalation could pose a serious threat to their stability and survival in the market. Frequently, ERP projects have crossed their estimated budgets and schedules. Researchers and practitioners state that a prevailing number of ERP adoption projects fail due to inaccurate or to too optimistic budgets/schedules. In addition, many organizations face difficulties in identifying the potential cost factors that could occur during their ERP adoption lifecycle. While focusing on the SME-context, this research attempts to identify potential costs that could occur in ERP adoptions. The research method employed in this study targeted diverse stakeholders and experts involved in ERP projects in Egypt. This research provides a list of cost factors and their classifications that could aid adopting organizations to better estimate their needed ERP project budgets. In particular, this research explores the direct and indirect cost factors that occur in ERP adoptions in Egyptian SMEs. Also, this study investigates the influence of some SME-specific contextual factors on costs. Moreover, the paper provides a ranking of cost factors according to their impact on total adoption costs.

    ERP lifecycle: A retirement case study2013In: Information Resources Management Journal, ISSN 1040-1628, E-ISSN 1533-7979, Vol. 26, no 1, p. 1-11Article in journal (Refereed)
    Abstract [en]

    A lot of research has been undertaken focusing on ERP systems lifecycles, but very little paid attention to retirement. ERP retirement means the replacement of an ERP with another. The aim of this research paper is to investigate why and when should organizations retire their ERP systems. A convenience case study of a SME has been selected from Egypt. The case study under investigation has retired their local ERP system and replaced it with SAP ERP. Results of the analysis indicate that reasons of retirement were: wrong selection, users were not involved in the selection process, and lack of an official implementation methodology. This is considered a new finding since main stream literature was mainly focused on retirement after maturity. Copyright © 2013, IGI Global.

    The Readiness of ERP Systems for the Factory of the Future2015In: Procedia Computer Science, ISSN 1877-0509, E-ISSN 1877-0509, Vol. 64, p. 721-728Article in journal (Refereed)
    Abstract [en]

    In 2011, at the Hanover Fair, the term Industry 4.0 was first coined. In October 2012, the Working Group on Industry 4.0, presented a set of implementation recommendations to the German government. The term Industry 4.0 initiates from a project in the high-tech strategy of the German government. Such project advocates the computerization of the manufacturing industry. It is also known as the 4th industrial revolution. Precisely speaking, industry 4.0 is based on the technological concepts of cyber-physical systems, Internet of Things (IoT), which enables the Factory of the Future (FoF). Within the modular structured smart factories of Industry 4.0, cyber-physical systems monitor physical processes, create a virtual copy of the physical world and make decentralized decisions. Over the IoT, Cyber-physical systems communicate and cooperate with each other and with humans in real time. Enterprise resource planning (ERP) systems are considered the backbone for the Industry 4.0. Thus, this paper attempts to answer the research question: “Are today’s ERP systems ready for the FoF?”. We have conducted interviews with manufacturers, ERP vendors, and partners in order to check on the readiness of ERP systems for the FoF. Our results show that ERP systems are ready for the FoF.

    Cloud ERP Systems: Anatomy of Adoption Factors & Attitudes2015In: Journal of Enterprise Resource Planning Studies, ISSN 2155-4781, E-ISSN 2155-4781, Vol. 2015, article id 521212Article in journal (Refereed)
    Abstract [en]

    Enterprise resource planning (ERP) systems have always been of interest to researchers across various research disciplines. Recently, the cloud computing paradigm has emerged to become one of most prominent technologies in business and academia alike. These new cloud accessibility and software delivery models have radically revolutionized the software market, especially ERP systems. However, while many vendors and software providers have adopted software-as-a-service (SaaS) models, few studies have explored the domain of cloud-based ERP systems – particularly information technology (IT) officers’ attitudes toward these technologies. Based on our review of literature and the relevant theories, we created a questionnaire and sent it to IT executives in Norwegian companies. The questionnaire captured the respondents’ perceptions of the benefits and disadvantages of cloud ERP. In general, the results confirm what has been reported in the literature. There were, however, some notable exceptions. One of the significant exceptions was the evident lack of data security concerns among the respondents, who ranked it as the least of their concerns. In addition, the promise of lowered total cost of ownership was not perceived as an appealing benefit, unlike what has been widely discussed in literature. Our findings show that respondents deemed vendor dependency and lock-in to be the paramount concerns of such cloud technologies, and system accessibility to be the significantly most advantageous. Finally, descriptive and inferential statistical analyses were conducted in this paper, and a regression analysis of the results was performed to identify the level at which the various benefits and advantages most affected our respondents’ attitudes.

    Perception of SaaS Adaption in Norwegian Enterprises: focus on ERP2014In: NOKOBIT - Norsk konferanse for organisasjoners bruk av informasjonsteknologi, ISSN 1892-0748, E-ISSN 1894-7719, Vol. 22, no 1Article in journal (Refereed)
    Abstract [en]

    Despite the vast amount of research that has been conducted on enterprise resource planning (ERP) systems and Cloud/ software-as-a-service (SaaS) in isolation, few studies have explored the topic of Cloud/SaaS ERP – particularly attitudes held towards these systems. Based on an assessment of literature and the Theory of Planned Behavior, a questionnaire focusing on benefits and disadvantages of SaaS-based ERP systems was sent to IT officers in 839 Norwegian companies. Responses from 180 companies helped to shed light on attitudes towards SaaS ERP adoptions. To a certain extent, the results come inline with existing research. There were, however, a couple of noteworthy exceptions. One such was the rather surprising lack of data security concerns amongst the respondents, who ranked it to be the least of their concerns. Another surprise was that despite strong indications found in literature, the promise of lowered Total Cost of Ownership was not perceived to be ensnaring benefit. Instead, respondents viewed vendor dependency to be the least favorable trait of such systems, and accessibility to be the significantly most advantageous. A regression analysis of the results was performed to identify the level of which the various benefits and advantages affected respondents’ attitudes.

    Why benefits realization from ERP in SMEs doesn't seem to matter?2011In: 2011 44th Hawaii International Conference on System Sciences: (HICSS 2011); Kauai, Hawaii, USA, 4 - 7 January 2011 / [ed] Ralph H. Sprague, Piscataway, NJ: IEEE Communications Society, 2011, article id 5718960Conference paper (Refereed)
    Abstract [en]

    It is often argued that IT investments require active management practices for benefits realization. This applies also to enterprise resource planning (ERP) systems. As well, benefits realization efforts are assumed to create more value than they cost. Hence, the maturity of organizations should be increased and their cultures cultivated towards more rational benefits realization practices. Our study on ERP implementations in Egyptian medium-sized organizations, however, provides aberrant results that challenge the fundamental arguments for formal benefits realization practices. While investments in ERP are regarded as significant, and the projects challenging, formal benefits realization and investment evaluation practices are considered largely irrelevant. The reasons include the "self-evident" nature of ERP benefits, perceived difficulty and costliness of method use and suspicions on rationality of methods. A government policy to support ERP investments may also decrease incentives for further benefits optimization. Cost coordination of the implementation efforts, however, continues to be an issue

    Abstract [en]

    This review summarizes research on enterprise resource planning (ERP) systems within the domain of small and medium-size enterprises (SMEs). Due to the close-to-saturation of ERP adoptions in large enterprises (LEs), ERP vendors now focus more on SMEs. Moreover, because of globalization, partnerships, value networks, and the huge information flow across and within SMEs nowadays, more and more SMEs are adopting ERP systems. Risks of adoption rely on the fact that SMEs have limited resources and specific characteristics that make their case different from LEs. The main purpose of this article is to shed the light on the areas that lack sufficient research within the ERP in SMEs domain, suggest future research avenues, as well as, present the current research findings that could aid practitioners, suppliers, and SMEs when embarking on ERP projects. Moreover, this research highlights the theories, frameworks, and research approaches and methods currently adopted in ERP for SMEs literature

    Back-Propagation Artificial Neural Network for ERP Adoption Cost Estimation2011In: ENTERprise Information Systems: International Conference, CENTERIS 2011, Vilamoura, Portugal, October 5-7, 2011, Proceedings, Berlin: Encyclopedia of Global Archaeology/Springer Verlag, 2011, Vol. II, p. 180-187Conference paper (Refereed)
    Abstract [en]

    Small and medium size enterprises (SMEs) are greatly affected by cost escalations and overruns Reliable cost factors estimation and management is a key for the success of Enterprise Resource Planning (ERP) systems adoptions in enterprises generally and SMEs specifically. This research area is still immature and needs a considerable amount of research to seek solid and realistic cost factors estimation. Majority of research in this area targets the enhancement of estimates calculated by COCOMO family models. This research is the beginning of a series of models that would try to replace COCOMO with other models that could be more adequate and focused on ERP adoptions. This paper introduces a feed-forward back propagation artificial neural network model for cost factors estimation. We comment on results, merits and limitations of the model proposed. Although the model addresses SMEs, however, it could be extended and applied in various environments and contexts.

    A roadmap for big-data research and education2015Report (Other academic)
    Abstract [en]

    The research area known as big data is characterized by the 3 V’s, which are vol- ume; variety; and velocity. Recently, also veracity and value have been associated with big data and that adds up to the 5 V’s. Big data related information systems (IS) are typically highly distributed and scalable in order to handle the huge datasets in organizations. Data processing in such systems includes creation, retrieval, storage, analysis, presentation, visualization, and any other activity that is typical for IS sys- tems. Big data is often associated with business analytics, cloud services, or industrial systems.This document presents a brief overview of the state of the art in selected topics of big data research, with the purpose of providing input to a roadmap for research and education at Lule ̊a University of Technology (LTU). The selection of topics is based on assessments of where LTU can make an impact based on current and anticipated research strengths and position with industry (e.g., process industry, data centers and cloud application providers). Topics include distributed systems, mobility, Internet of Things, and advanced analytics.

    As a part of the on-going DURAARK project, this review summarizes research on long term digital preservation (LDP) of 3D architectural data related to architecture, engineering, and construction, within the domain of libraries, museums, archives, and small and medium sized enterprises (SMEs). The paradigm shift from 2D to 3D modelling raised new challenges for long-term preservation of the architectural data. For example, the original 3D models and the actual state of built architectures might lose fidelity in the long run because of environmental influences and systematic changes. Likewise, the access mechanisms of current preservation systems in the architectural domain are based on simple metadata schemas inherited from the analogue world, for example searching with a card index. In the absence of standard process and LDP strategies for 3D architectural data, it would be difficult to store and retrieve the detailed semantic information from the archival systems in the long run. Considering the various challenges in capturing, preserving, retrieving, and securing the 3D architectural data, this literature review is an endeavour to synthesize the current research findings and highlights the areas that lack sufficient research with regard to long term preservation of 3D architectural data. The paper employs open archival information systems (OAIS) models, a de facto standard for the LDP, to analyse the shortlisted publications. Finally, the paper presents on-going efforts and goals of DURAARK, an EU funded project.

    ERP systems in SMEs: A literature review2011In: 2011 44th Hawaii International Conference on System Sciences: (HICSS 2011); Kauai, Hawaii, USA, 4 - 7 January 2011 / [ed] Ralph H. Sprague, Piscataway, NJ: IEEE Communications Society, 2011, article id 5718924Conference paper (Refereed)
    Abstract [en]

    This review summarizes research on enterprise resource planning (ERP) systems in small and medium-size enterprises (SMEs). Due to the close-to-saturation of ERP adoptions in large enterprises (LEs), ERP vendors now focus more on SMEs. Moreover, because of globalization, partnerships, value networks, and the huge information flow across and within SMEs nowadays, more and more SMEs are adopting ERP systems. Risks of adoption rely on the fact that SMEs have limited resources and specific characteristics that make their case different from LEs. The main focus of this article is to shed the light on the areas that lack sufficient research within the ERP in SMEs domain, suggest future research avenues, as well as, present the current research findings that could aid practitioners, suppliers, and SMEs when embarking on ERP projects
