Prescriptive process models advocate for orderly and structured approaches to software engineering. However, if these models strive for too much order, they may be inappropriate for an evolving software world that thrives on change. Yet rejecting traditional structured models could make it impossible to achieve coordination on software projects. The document then describes several prescriptive process models including the waterfall model, incremental model, RAD model, and evolutionary models like prototyping, spiral development, and concurrent development. It also mentions other approaches like component-based development, formal methods, aspect-oriented software development, and the unified process.

2. Prescriptive Models Prescriptive process models advocate an orderly approach to software engineering That leads to a few questions … If prescriptive process models strive for structure and order, are they inappropriate for a software world that thrives on change? Yet, if we reject traditional process models (and the order they imply) and replace them with something less structured, do we make it impossible to achieve coordination and coherence in software work?

Still Other Process Models Component based development —the process to apply when reuse is a development objective Formal methods —emphasizes the mathematical specification of requirements AOSD —provides a process and methodological approach for defining, specifying, designing, and constructing aspects Unified Process —a “use-case driven, architecture-centric, iterative and incremental” software process closely aligned with the Unified Modeling Language (UML)
