Quality-Attribute Based Economic Valuation of Architectural Patterns

Architectural patterns generate value depending on the utility of the quality attributes that can be achieved from the application of those patterns. However, methods to rigorously evaluate the value-added of patterns do not exist. In this position paper, we make the case that architectural patterns carry economic value in the form of real options, providing designers with the right, but not the obligation, to take subsequent design actions in the future in the face of uncertainty. We summarize our observations in evaluating the relative value of patterns using real option valuation models on a model problem. We draw attention to how such economics-informed approaches can provide belter insights for the selection of situated design strategies.
