Most of today's software development projects depend on the usage of existing solutions to save time and development costs. We target in this research work the design of a software capability profile that provides a broader view of an organization’s software, along with an exploitation model in line with requirements engineering and enterprise architecture to fill the gap between the goals of the stakeholders and what can be delivered as a practical solution. Our contribution aims to improve the reuse of existing software, by upgrading these technical components to the level of end-user's requirements for accelerating future business application development
