This work is an exhaustive approximation to the conceptualization phase of the production of massive courses. It takes the knowledge from the experiences in MOOCs at the Universitat Oberta de Catalunya (UOC) as base, but also other MOOCs¿ experiences around the world. The result of this work is conceived as a accompanying tool that serves to give answer to questions about the management implications of the massive courses production and the needed resources. It is addressed specifically to the UOC professionals who participate in the production of this kind of courses.
