: The Open University's M880 Software Engineering is a postgraduate distance education course aimed at software professionals. The case study element of the course (approximately 100 hours of study) is presented through an innovative interactive multimedia simulation of a software house Open Software Solutions (OSS). The student "joins" OSS as an employee and performs various tasks as a member of the company's project teams. The course is now in its sixth presentation and has been studied by over 1500 students. In this paper, we present the background to the development, and describe the multimedia and its use by students.
