The increasing growth in popularity of Web services has made it difficult for business users to fully benefit from these services if they remain specified at the software level. The introduction of intentional services is an alternative for bridging the gap between low level, technical software-service descriptions and high level, strategic expressions of(More)
The approach presented in this work aims to guide the companies in their design of requirements traceability models adapted to the context of their projects. This is achieved by allowing the construction of a model based on trace fragments adapted to each phase of the development process or to a specific situation. Furthermore, the approach guides the users(More)
