MORALE
Mission ORiented Architectural Legacy Evolution

The goal of the MORALE project is to facilitate the evolution of legacy software systems. Facilitation takes the form of improved quality by requirements validation, reduced risk via architectural evaluation and assessment, and increased productivity from maintenance and access to design rationale and from high level reuse of architectural components.

MORALE exploits both high level (mission-oriented) requirements and existing software assets in order to predict the extent to which new system requirements perturb an existing system version. Requirements are derived from mission-oriented goals and are explored through scenarios, and the existing system is analysed in terms of its response to high-level events traces (scenario instantiations). These inputs are expressed in a scenario-based architectural description language. The common representation enables predictions of architectural distortions as well suggesting reuse candidates.
