La Fageda is a manufacturer of high-quality, naturally-made yogurts in northern Catalonia, Spain. La Fageda is substantially different from its main competitors such as multinational Danone in that it is a 270-person workers' cooperative with 60 percent of its membership made up of mentally disabled individuals. Since its establishment in 1982, the organization has aimed to integrate the mentally disabled by providing meaningful jobs and dignified salaries. As of March 2010, La Fageda has opened up a new production facility to make ice cream in an urban area outside of its well-known agricultural farm. Students are faced with understanding La Fageda's business model and how it competes against multinationals.

This note defines the concepts of business model and the value loop. It also introduces business model representations and proposes four tests for evaluating business models in isolation. This is the first note in a series of three written for the HBS elective course "Competing through Business Models."
