Abstract [en]

The purpose of the study is to model the micro-scale process patterns which can be identified during team conceptual design activities. A state-transition model has been developed and used to empirically investigate the patterns of design operations during two types of team conceptual design activities: ideation and concept review. The presented work builds on the perception of design problems as ill-defined and implies that conceptual design activities involve the simultaneous development of problems and solutions using three distinctive design operations—analysis, synthesis, and evaluation. The three design operations have been defined as fine-grain design steps performed by design teams when exploring the content of both the problem and the solution dimensions of the design space. Moreover, design operations have been conceptualised as transitions between states of the explored design space, thus providing a basis for the state-transition model. The model’s ability to map and visualise proportions of design operation sequences emerging during ideation and concept review has facilitated the identification of both the activity-specific patterns and patterns that were likely to appear during both types of empirically investigated activities. The two activities exhibited similar patterns, such as alternation of solution synthesis and analysis, sequences of synthesis, analysis and evaluation within solution space, and the potential co-evolution episodes. Nevertheless, divergent traits have been identified for ideation, and convergent traits for concept review, based on the significant differences in proportions of design operations and their sequences.

Abstract [en]

Developing new technologies is one of the most important goals of today’s scientific and industrial research. Understanding how technology evolves, as well as its current state, is invaluable in an ecosystem where technology is evolving at an increasingly rapid pace. In this paper, patent data is used to determine a technology’s life cycle. Two patent maps are created, one based on patent citations and one based on keywords. The citation patent map visualizes how patents cite each other, while the keyword patent maps visualize keywords used to describe patents and their relations. Both of these patent maps are dynamic, meaning they change over time thus giving insight into an examined technology’s evolution. A growth analysis of both networks is conducted as well as a degree distribution analysis. Both of these analyses are used to help determine the technology’s lifecycle phase as well as its patterns of growth. This insight is invaluable to stakeholders tasked to make strategic decisions related to technology development.

Abstract [en]

The success of product development highly depends on the quality of cooperation among members of a team involved in the process. Thus, a tool capable of simulating product development team may be beneficial for researchers interested in teamwork, as well as useful for managers struggling with team formation during process planning phase. This work aims at providing a detailed overview of agent-based simulators of product development teams. Specifically, the scientific databases Web of Science, Scopus, ACM DL, and IEEE were searched to extract relevant agent-based models of teamwork in mechanical engineering and aerospace context and obtained models were reviewed to identify their key advantages and limitations.

Abstract [en]

Recent developments in engineering design management point to the need for more dynamic, fine-grain measurement approaches able to deal with multi-dimensional, cross-level process performance in product design. Thus, this paper proposes a new approach to the measurement and management of individual and teamwork performance in engineering design projects. This integrates multiple, previously disparate, aspects of design management and performance measurement theory in a single framework. Further, a fully realised performance measurement approach is developed, which complements existing management strategies. This framework is synthesised from an extensive review and illustrated via an in-depth case study. As such, this work contributes to performance measurement theory in engineering design and has significant implications for both engineering design research and industry.

Abstract [en]

The process of innovation takes significant resources, and therefore it is of great importance for companies to recognize the ideas with high innovation capacity as early as possible, and in a transparent manner, with the least necessary amount of expert knowledge. Current research indicates that companies often carry out the selection of ideas ad hoc or intuitively, and that only a small number of companies have defined the methods for ideas assessment and evaluation. In doing so, such problems as imprecise definition of the variables used in the evaluation process of the innovation capacities of ideas, undefined metrics and interaction variables will arise. In order to determine the practical points of view in this area, a study was conducted in the form of a survey on a representative sample of Croatian companies which have product innovation in their production program. The survey is aimed at determining what motivates companies to innovate, and the ways in which companies carry out the assessment and selection of ideas. Through a thorough study of the literature, a set of variables that are commonly used in the idea capacities assessment for product development have been defined, and the survey tried to establish the practical significance of individual variables for the participants of the process. This paper presents the results of the study.

Abstract [en]

The competitiveness of the economy to a large extent depends on its ability to innovate. There is a consensus between researchers and business practices on the high importance of innovation management process, particularly in the earliest stage when it is necessary to identify business opportunities and find the best possibilities for their realizations. In the process of innovation management, many authors emphasize the critical role of idea management and efficient ways of creating, gathering, evaluation, promotion, selection, and implementation of ideas. As part of the research project "Models and methods of knowledge management in product development", by the Croatian Ministry of science, education and sport, a survey was conducted on a sample of Croatian companies which have product development in their production process. The conducted survey attempted to determine the situation in the area of product innovation, as well as in the field of innovation and idea management in the economy and to compare data with best practices. The collected data show when and how the ideas are collected, which motives and purposes are drivers for the collection of ideas and how companies are organized and trained for this demanding job. This paper presents the results of the survey, which suggest ways to improve product development, and sources and methods of collecting ideas. Publication of the outcome of this and other research on product innovation aims to spread the knowledge about this very important but under-explored area

Abstract [en]

For effective management of development projects, it is necessary to take into consideration its socio-technical perspective – working processes, teamwork and features of the working environment. Data gathering about socio-technical aspects of the product development activities is often hampered by constraints of the actual working environment in R&D organizations. For that reason, to support practical data collection, the work sampling application for mobile phones has been introduced. The work sampling application consists of sequence of input screens with predefined input menus enabling data gathering about different aspects of the product development activity (such as work type, activity type, context, participants, execution manner, information transaction and motivation). For validation of the proposed application, the empirical study was carried out in the company whose research and development activities are focused on the systems for the generation, distribution and transformation of electrical energy.

Abstract [en]

The objective of the research presented in this paper is to develop an algorithm for predicting behaviour of complex technical systems in an uncertain working environment. System's dynamic behaviour modelling and simulation should help to develop new and improve existing architectures of complex technical systems by mapping in both directions, from the structural to the behavioural domain and vice versa. The algorithm for predicting behaviour during system's architecture development consists of several operations shortly described in this paper. The proposed algorithm was verified on an example of a complex technical system - an air-handling unit.

Abstract [en]

By embracing insights from project management and intellectual capital measurement research fields, basis can be established for development of new performance indicators for monitoring intangible project aspects of individual and team work within the product development context. Focusing on individual and team level of product development projects, data gathering is hampered by constraints of the real organizational environment. Therefore, in this research paper, development of work sampling self-report application is presented which allows data capturing for real-time measurement of intellectual capital elements in a practical and straight-forward way. Preliminary work sampling study was executed in R&D company whose main preocupation is development of the electro-mechanical devices for distribution and transformation of the electrical energy within the energy infrastructure or mass transportation systems. Information about potential trends of particular underperforming values related to the communication and information sharing, innovativeness/ideation and motivation/satisfaction on individual or team level, could provide added value for the project managers and decision makers.
