The University of Valencia, in accordance with Spanish and European regulations, has implemented an Internal Quality Assurance System that establishes procedures and evidences that allow one to conduct and document the analysis, evaluation and continuous improvement in Higher Education processes. The correct monitoring of the processes and the proper storage of documentary evidences must be secured, and the most efficient way for that purpose is a computer platform using Business Process Management (BPM) tools. This work presents the design of such a Quality Assurance System, the technological details of the computer platform underneath and the experience collected during several years of usage.
