PRODUCT DESIGN SCHEMATICS: STRUCTURED DIAGRAMMING FOR REQUIREMENTS ENGINEERING
The authors have developed a systematic diagrammatic approach to represent design problem requirements as part of a larger project on visualising design information. Product design schematics (PDS) are based on concept maps but also draw from other research efforts in design problem analysis. PDSs distinguish between product characteristics, functional requirements, constraints, and performance metrics. The approach is explained with examples. The authors are currently developing a computer-based tool to support PDS creation and use. Anecdotal evidence suggests that the PDS approach can help designers reach a deeper understanding of design problems more quickly and easily than other approaches.
