D 1.3. (October 2007)

This document describes the work done and results obtained in task 1.3 (“Definition of Metrics Systems and Prototype Quality Models”) and in task 1.2 (“Goal of measurements”) of the QualOSS project. We review relevant definitions of robustness and evolvability in F/OSS assessment approaches and in the state of the art and practice of quality models. Additionally, we take into account stakeholders' perceptions and requirements through a series of interviews. Goals and requirements for the QualOSS model are defined in terms of (a) business and measurement goals, and (b) a consolidated definition of quality characteristics for evolvability and robustness from related work and from stakehoders' views, and (c) an initial plan for validation of the QualOSS model.
