At least one design diagram is obtained from at least one previous software project. At least one service abstraction is extracted from the at least one design diagram. The at least one service abstraction is reused in a new software project. In another aspect, requirements are obtained for a current software project; at least one class diagram is obtained from at least one previous software project; a dependency graph is generated from the at least one design diagram, using link analysis; relationships between classes in the dependency graph are analyzed to obtain functional artifacts for the requirements; and the functional artifacts are reused in the new software project.
