Description
Ipek Ozkaya from the Software Engineering Institute (Pittsburgh) is visiting us and vill give a seminar on Architecture EvolutionArchitecture evolution, a key aspect of software evolution, is typically done in an ad hoc manner, guided only by the competence of the architect performing it. This process lacks the rigor of an engineering discipline. In this presentation, I argue that architecture evolution must be engineered— based on rational decisions that are supported by formal models and objective analyses. Evolutions of a restricted form — close-ended evolution, where the starting and ending design points are known a priori — are amenable to being engineered. I discuss some of the key challenges in engineering close-ended evolution. I present a conceptual framework in which an architecture evolutionary trajectory is modeled as a sequence of steps, each captured by an operator. The goal of this framework is to support exploration and objective evaluation of different evolutionary trajectories. I present an example evaluation of such a trajectory and conclude with open research questions in developing such a framework.
