Squale in a nutshell

To help you deal with the quality of your software developments, the open source Software QUALity Enhancement project (aka Squale) focuses on two main aspects:

  • Works on enhanced quality models
    • inspired by existing standards (ISO-9126) and approaches (GQM, McCall),
    • validated and improved by famous researchers who are part of the Squale team,
    • dealing of both technical and economical aspects of quality,

  • Development of an open-source application that helps assessing software quality and improving it over time
    • based on third party technologies (commercial or open-source) that produce raw quality information (like metrics for instance),
    • using the quality models to aggregate this raw information into high level quality factors,
    • all this targeting different languages, including Java, C/C++, .NET, PHP, Cobol, ...

Squale is an open-source project!
