1 Towards Strategic Reuse in Project-Oriented Environments by Using Software Product Line Practices

Abstract. Software product line engineering has become a widely used and popular approach for developing products that are targeted at a specific market. Strategic reuse is a key factor in its success. Large organizations, such as in the financial industry, cover large domains and thus have huge existing infrastruc-tures running in separate business units. Systems running on these infrastruc-tures have been separately built in each business unit using a project-oriented approach. This implies that a system is built to satisfy a single user’s require-ments, thus there is a high possibility of duplicate systems occurring across business units of an organization, costing them enormous amounts of money. In order to reduce development and maintenance costs for these organizations, we propose a product line-oriented approach to incorporate strategic reuse into ex-isting infrastructures of large organizations. These concepts have not been ap-plied at a level of granularity that is most beneficial for large organizations. Our approach facilitates the entry of product line practice into large organizations by means of requirements analysis, separation of concerns and feature model-ling.
