Implicit Priorities in Adaptation Requirements

The increasing need for adaptive systems has led to the creation of many frameworks aiming to support their development. Nonetheless, the implementation of requirements related to adaptation, just as of any other kind of requirement, comes at a cost. In being so, it is necessary to consider requirements' priorities when creating such systems. In this work we analyze the relationship between requirements prioritization and software adaptation. In particular, the following questions are tackled: is the use of requirements-based adaptation frameworks somehow affected by requirements' priorities? Does the use of said frameworks affect requirements' priorities? Through an analysis of selected frameworks, we have found evidences that suggest positive answers for both questions. In this paper we present our findings as well as an initial proposal for interlacing prioritization activities with adaptation activities.
