Fit As a Diagnostic Tool: An Analytic Review of Approaches to Measure Correspondence Between Technical and Organizational Architectures

Standardized design approaches such as those embodied by concurrent design facilities have many benefits, such as increased efficiency of the design process, but may also have hidden costs. Specifically, when their standardized organizational decomposition is a poor fit for the particular design problem, important design trades might be missed or poor decisions made. Before we can understand how this lack of fit impacts the design process, we must be able to empirically observe and measure it. To that end, this paper identifies measures of “fit” from the literature along with attributes likely to impact design process performance, then evaluates the measures to determine how well the measures can detect and diagnose potential issues. The results provide comparative insights into the capabilities of existing fit measures, and also build guidance for how the systems engineering and design community can use insights from the “fit” literature to inform process improvement.
