Measuring Reuse in an Object Oriented Process

This paper presents a number of results about reuse in a real life project. . The project, called AEFTA, develops a factory automation application (a FMS cell controller) using commercially available tools: DEC BASEstar Open a shop-floor distributed system for application integration; and SYCO G++ an object-oriented environment with a large library of C++ classes (data structures, GUI building, concurrency and distribution) and a set of integrated CASE tools to support a smooth transition from analysis to design, implementation and distribution. The figures from reuse are very high but they have to be balanced with the effort for familiarizing with the class libraries and the required experience of the staff. The European Commission, DGIII/F funded, under contract ESSI 10070, the AEFTA project.
