Engineering software reuse for on-board embedded real-time systems

The dimensions of concern to ambitious reuse initiatives largely exceed the provision of desired functionalities. A domain-specific blend of functional, technical and quality considerations determines the reuse potential of software reuse assets. In a recent project we realised considerable reuse dividends from coupling the definition of a reference software architecture and of an associated set of standard interfaces with the selection of a powerful computational model equipped with reuse-geared enabling technology. In this paper we present our engineering approach to the project and show how it earned us a good balance between the preservation of predictability and scalability and the maximisation of the reuse objective.
