The process of developing courseware (i.e. web-based, hypermedia courses) has similarities with the traditional software development, since the result of both processes is a software product. In order to avoid adhoc-developments software engineering approaches are also necessary for the courseware development. Our process model describes the courseware development process and consists of the phases analysis, design, implementation and application/maintenance. Parallel to these phases project management activities run. In the analysis phase educational goals, content and target groups are defined. The content, the educational scenario, the data and the user interface are modelled in the design phase. The implementation phase is consisting of the activities authoring in-the-small and authoring in-the-large. At last the courses will be used and evaluated. The re-use of courseware plays an important role in the process model. The content will be modularised and different courses are built re-using the same education modules; separating content from its presentation makes it possible to define different views on the same content, and extending the education modules with standardised metadata facilitates a further search and re-use of courseware.
