Knowledge Base Repository

In addition to research papers, the Design Society is developing several valuable resources for those interested in the study of design. These include a repository of PhD theses, a library of case studies and transcripts of design activities, and an archive of our newsletters. Please note that these resources are accessible exclusively to Design Society members.

Abstract:
Engineering change requests are important and plentiful in the product development process to enhance a product. In this paper we use Markov chains on ECRs in a large product development project and display the results in a Markov chain DSM. The DSM shows statistical probability of a transition pathway for an industrial design process and together with engineering domain knowledge we identify patterns and improvement opportunities. It turns out that 8% of ECRs are closed directly after creation, most common pathway is not followed in early statues and status iterations are seen in the DSM.
