Acquiring COTS software selection requirements

The authors describe their design of Procurement Oriented Requirements Engineering, using knowledge gained from past studies of real-world requirements acquisition for complex product selection. PORE is built from existing requirements engineering and knowledge engineering techniques, feature analysis, multicriteria decision making, argumentation, and template-based approaches. The authors recount their experiences applying PORE to help a UK Ministry of Defense team devise requirements for a new naval platform. They report on 11 problems encountered during the project and how their solutions to them will be incorporated in future versions of PORE.
