We have studied the importance of quality at every stage of development by examining the quality life cycle stages, commencing with discovery and refinement, which occur parallel to business features discovery and refinement. The QAW is one of the most critical activities for architects to discover and prioritizes quality attributes by engaging all stakeholders identified using a stakeholder matrix.
