Using Goal Models to Visualize and Prioritize Requirements for Learning Management Systems

Learning Management Systems (LMSes) handle all aspects of the learning process, a crucial part of educational technology. This study elicits and models the functional and non-functional requirements of two academic and one industrial LMS. The overall purpose is to provide a general requirements model, grounded on existing systems and collected evidence, to aid future LMS development. Goal models, partially validated with interviews, are used to provide a visual presentation of LMS functional and non-functional requirements. A survey was used to prioritize these requirements, obtaining 63 responses from students and academics in Software Engineering. The prioritized requirements are used to create a general LMS requirements model.
