One of the core aspects of a MUTW-like course unit is the students' project. To begin with, it should be some realistic product with a real interest to some group or community so that students feel they are really contributing with their work to some major goal. Additional care is required to assure that the system can be organized in a set of packages that are consistent with the workloads required from each of the team members. It should be taken into account that MUTW-like courses demand for a high effort on team management and this should also be accounted for when measuring workload. Another core issue is not to provide a full specification to students. The specification provided to students should have some unspecified issues to force and promote discussion and communication, thus contributing to the development of soft skills in students. In this chapter we present the main aspects related to the students' project that we have used in both editions of MUTW that ran during the pilot period, including a detailed description of the project specification that has been provided to students.
