The squale model - A practice-based industrial quality model
نویسندگان
چکیده
ISO 9126 promotes a three-level model of quality (factors, criteria, and metrics) which allows one to assess quality at the top level of factors and criteria. However, it is difficult to use this model as a tool to increase software quality. In the Squale model, we add practices as an intermediate level between metrics and criteria. Practices abstract away from raw information (metrics, tool reports, audits) and provide technical guidelines to respect. Moreover, practice marks are adjusted using formulae to suit company development habits or exigences: for example bad marks are stressed to point to places which need most of the attention. The Squale model has been developed and validated over the last couple of years in an industrial setting with Air France-KML and PSA Peugeot-Citroën.

SQUALE - Software QUALity Enhancement
The Squale project was born from industrial effort to control software quality. Its goals are to refine and enhance Qualixo Model, a software-metric based quality model already used by large companies in France (Air France-KLM, PSA Peugeot-Citroën) and to support the estimation of return on investment produced by software quality. Qualixo Model is a software quality model based on the aggregati...
متن کاملSoftware quality metrics aggregation in industry
With the growing need for quality assessment of entire software systems in the industry, new issues are emerging. First, because most software quality metrics are defined at the level of individual software components, there is a need for aggregation methods to summarize the results at the system level. Second, because a software evaluation requires the use of different metrics, with possibly w...
