Options Analysis for Reengineering (OAR): A Method for Mining Legacy Assets
John Bergey, Liam O’Brien, Dennis G. Smith · Defense Technical Information Center (DTIC) · 2001
Options Analysis for Reengineering (OAR) is a systematic, architecture-centric, decision making method for mining existing components for a product line or new software architecture. OAR's five activities identify potential components, estimate the mining cost, and evaluate the effort required to reuse legacy components. OAR reveals implicit stakeholder assumptions, constraints, and other major drivers that affect component mining, thereby giving managers insight into this complex task.
