This case describes a classroom activity that explores a fictional software product company to help students learn about ways that businesses make money from software, including Free & Open Source Software (FOSS). The activity shows how a company might evolve through different business models, but does not imply that some models are always better than others. Each section of the activity develops specific concepts, so an instructor could choose desired sections. The activity is designed for Process Oriented Guided Inquiry Learning (POGIL), an evidence-based approach to teaching and learning in which student work together in teams to understand key concepts and develop skills such as teamwork, communication, and critical thinking. This case includes relevant background on software business models, FOSS, and POGIL; teaching notes for the case; and the student version in an appendix.
