Abstract:

This article introduces three matrix methods - Design Structure Matrix (DSM), Domain-Mapping Matrix (DMM), and Multi-Domain Matrix (MDM) - that represent the relationships, interfaces, and dependencies among the elements comprising various systems, including those involved in the development and management of technical systems, thereby making the design of the structure or architecture of a system more transparent and analyzable, and improving system innovation and management. Matrix-based representations provide powerful, alternative viewpoints in system architecture frameworks.

Description:

This article is intended to introduce the basics of matrix-based methods for modeling, analyzing, and managing complexity across domains, with a focus on the design perspective. Under the name of Dependency and Structure Modeling, an annual, international conference (DSM conference), is organized by a grown community of DSM experts around the globe. This event has been endorsed by the Design Society for many years, under the leadership of the University of Stuttgart. As part of the discussions within the conference's community on how to improve the access to this field for newcomers, a foundational book chapter-style article was wished for. Therefore, three members of the DSM Organizing Committee and experts in the field themselves have written this publication which is made freely available for personal reading, downloading, and academic reference. We hope to raise interest in this important field within the Design Society with this article.
