Architecturally significant requirements (ASRs) drive and constrain many aspects of architecture. Eliciting and analyzing these requirements in the early phases of a project means that quality concerns can be discovered and addressed during the architectural design. This reduces the risk of costly and unnecessary refactoring. The challenge of emerging requirements is particularly evident in agile projects, which are inherently incremental; however, existing techniques for eliciting ASRs, such as win-win and i*, are typically rejected by agile development teams as being somewhat heavyweight. In this chapter, we present the notion of an architecturally savvy persona (ASP), which is used to emerge and analyze stakeholders’ quality concerns and to drive and validate the architectural design. ASPs are useful for discovering, analyzing, and managing ASRs, and designing and validating high-level architectural solutions that balance tradeoffs and satisfy stakeholders’ concerns. We show how ASPs can be used to discover quality concerns, drive architectural design, and preserve architectural qualities during long-term maintenance activities.
