Releasing the Power of Variability: Towards Constraint Driven Quality Assurance

Abstract

We identify that Over Design(OD) and Under Design(UD) as two basic forms of negative variability construction which can lead to both functional incompleteness and unexpected quality of both design time and run time. To make our approach practical to a whole software production processes, we propose to evaluate and measure OD and UD in terms of values under economical goals which are concretized with the functionality implementation and the quality management of a quality lifecycle. We work towards relieving OD and UD in terms of variability construction within a variability space.
