Cost-benefit analysis of courseware development using IntView
Abstract
In software industry, there is a lack of high-quality courseware for the training of the workforce. Therefore, the number of projects producing courseware is increasing. In order to avoid that these projects suffer from the same problems as traditional software projects, i.e. schedule and budget overruns, Fraunhofer IESE developed the IntView process model for efficient high-quality courseware development. IntView defines an engineering-style process that combines existing courseware development approaches with established and evaluated software engineering methods and techniques. Particular focus is put on the integration of life-cycle encompassing quality assurance activities. This paper presents the phases and main products of the IntView process model, and its pilot application for the development of courseware on UML supporting the training of software designers. In the focus of the presentation is the description of a case study that first analyses the effort spent for developing the UML courseware with IntView and then compares the effort distribution with data from previous courseware development where IntView was not yet available. The empirical study indicates that the development effort to delivery time ratio is considerably smaller for the courseware developed with IntView. The savings can mainly be attributed to the introduction of quality assurance activities in early development phases and the reduction of rework effort caused by defects detected during product evaluation. The overall rework effort reduction by far outweighs the effort generated by the life-cycle encompassing quality assurance activities of IntView.
