CS PhD Advanced SE Pr S. Ghoul, 2018 Software Engineering Conventional Process overview 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?  Dynamic Process Model CS PhD Advanced SE Pr S.
