As resources become further constrained, options become more numerous, and goals become increasingly complex, it is more critical and more challenging for design teams to find these integrated solutions. Theory proposes the integration of transformation, flow, and value views as necessary to support such integrated design. This paper develops requirements for these views that encourage flexible yet systematic integrated conceptual design processes. It then illustrates how these requirements are only partially satisfied by current design management systems, provides motivating case studies, and introduces a new framework, multiattribute interaction design (MAID), to fill this void by systematically guiding design teams to explicitly consider the potential interactions of options and the resulting value of design solutions.

Current practice fails to reliably generate high-performing alternatives in part because it lacks systematic means to compare existing or emerging design processes. Researchers lack empirical methods and data to evaluate design challenges and the strategies available to address them. In this paper, we document and then apply the DEAM to the professional implementation of six design strategies across two design challenges using the charrette test method. The results are used to compare the strategies according to the performance of the solution(s) generated. For the strategies and challenges investigated, more information during design does not always assist the designer to produce better performing alternatives. We discuss possible explanations and conclude with a discussion of the strengths and weaknesses of the DEAM as an evaluation method. Initial findings demonstrate that the DEAM is a method capable of providing a meaningful comparison of strategies in the domain of energy-efficient design challenges.
