Abstract [en]

During product development, most of the customer value, as well as the cost and the quality of a product are defined. This key role of development in industry has led to an intense search for better ways to develop products, software, services and systems. One development methodology that has received positive attention is Set-Based Concurrent Engineering (SBCE). Some authors claim that SBCE and related practices from Lean Development are four times more productive than traditional development models. Unfortunately, SBCE is also described as hard to implement. This thesis presents the results of a three year research project aimed at implementing and describing the effects of Set-Based Concurrent Engineering in industry. The scope of the research is to use the principles of SBCE as a means to improve the productivity of industrial product development processes and its resulting products. The contribution of this work is a better understanding of Set-Based Concurrent Engineering and a support to implement its principles. The results show that SBCE gives positive effects on many aspects of product development performance and on the resulting products. The improvements are especially dominant on product performance, product cost and the level of innovation Moreover, a comparison between a Set-based decision process and a traditional matrix for design evaluation is presented, showing that these two approaches generate different results. The matrix evaluation promoted the development of new technology and the Set-based process promoted a thorough understanding of the important design parameters of the current designs. Finally, this work presents a structured design process and computer tool for implementing the principles of SBCE. The process was demonstrated by using information from an industrial development project, showing how the proposed process could implement the three principles of SBCE in a traditional Point-based development environment.

Abstract [en]

Decision-making and selection of different design alternatives is a central activity in product development. This paper compares the decision process of Set-Based Concurrent Engineering to Pugh’s method of controlled convergence in an industrial case study. The purpose is to investigate if the set-based decision process renders different results compared to the traditional Pugh matrix selection. In the case study, Pugh’s matrix promoted the development of new concepts. The set-based process offered the opposite approach, aiming at improving the currently used technologies.

Abstract [en]

Set-Based Concurrent Engineering is sometimes seen as a means to dramatic improvements in product design processes. In spite of its popularity in literature, the number of reported applications has so far been limited. This paper adds new information by describing implementations of Set-Based Concurrent Engineering in four product developing companies. The research took a case study approach, with the objective to investigate if the principles of Set-Based Concurrent Engineering can improve the efficiency and the effectiveness of the development process. The study shows that set-based projects can be driven within an existing organization, if given proper support. The participants claim that a set-based approach has a positive effects on development performance, especially on the level of innovation, product cost and performance. The improvements were achieved at the expense of slightly higher development costs and longer lead time. However, the positive effects are dominating and the companies involved intend to use Set-Based Concurrent Engineering in future projects when appropriate.

Abstract [en]

Set-Based Concurrent Engineering is described as an effective methodology for product development, but is also hard to implement in companies using traditional development processes. This paper suggests a new way to introduce Set-Based Concurrent Engineering by combining its three principles with a modified morphological chart. A structured process with design templates is proposed and incorporated in a computer tool. The approach is evaluated by using information from an industrial case study. The result indicates that the principles of Set-based Concurrent Engineering can be implemented in a traditional development process by the proposed process and computer tool.
