Treffer: and M.Soden “Significant Productivity Enhancement through Model Driven Techniques: A Success Story

This paper describes the automation and optimization of the software development process of NTT Data. The development process defines the business modeling, requirement capturing as well as, system planning and implementation activities to be carried out by the development project members. The target systems of this development process are large web based information systems implemented by leveraging Java/Java EE 5 technologies. The automation and optimization of that process was achieved by the application of model driven techniques, mainly the integration of development tools via a Meta Object Facility (MOF) repository backbone, the provision of automation by facilitating model transformations and code generation and by increasing the consistency and traceability of all development artifacts. An evaluation within NTT Data showed a development effort and time reduction of more than 50%. The main lessons learned form this case include the necessity of model-to-model transformations, the need to preserve advantage of existing development process and tools landscape, the requirements to care about configuration and change management from the beginning and requirements to support also non modeling tools. 1.
