By examining Ekal Vidyalaya (Ekal), a non-profit network of schools in India, this case focuses on the classic challenge faced by organizations that grow through replication (e.g., McDonald's, Whole Foods, Wal-Mart): how can they continue to drive growth when their well of attractive locations begins to dry? In 1986, a group of social entrepreneurs reimagined education in India, developing a low-cost, "one-teacher school" model to provide educational access in regions that had proven cost prohibitive for government schools. They founded Ekal to fulfill the vision of a network of 100,000 one-teacher schools throughout rural India. More than a quarter century later, the Ekal network now includes more than 54,000 schools. However, with the emergence of India as an economic power, government schools have received the mandate and funds to extend their reach to many of the regions that Ekal serves. It was time to for Ekal to reevaluate their vision. Was the target of 100,000 schools, which had driven their growth thus far, still the best path forward? Or was it time to declare their mission of universal access to education a success in the regions that government schools now served and begin to scale back from those areas?

The global consumer goods company Unilever was on pace to hit a number of aggressive targets by 2020 as part of the Unilever Sustainable Living Project, including a goal to halve the waste associated with the disposal of its products. Unilever's Chief Supply Chain Officer Pier Luigi Sigismondi and his team were working towards this goal and had chosen to first focus on three key areas-sugar, tomatoes, and tea-and had analyzed where in the 'farm to fork' value chain product was wasted. This analysis showed that very little was wasted within areas of the value chain directly controlled by Unilever, and most occurred either upstream with its suppliers or downstream with consumers. How could Unilever encourage these actors to change established practices and entrenched behaviors within a short timeframe to help Unilever meet its sustainability targets and also to improve the operations of its partners in the value chain? By encouraging consumers to better manage their food purchases, did Unilever risk harming its own sales or those of its retail customers? Could Unilever encourage industry-wide changes to have a real impact on global environmental sustainability?

The case examines the operations strategy of Whole Foods, one of the largest natural grocery chains in the United States. In late 2013, Whole Foods was expanding rapidly, with a publicly-stated goal of growing from 351 to 1,000 domestic stores by 2022. It was also engaged in a strategic initiative to combat "food deserts" - areas with limited access to affordable and nutritious food. In pursuit of these initiatives, the company's rapid entry into a heterogeneous set of new markets necessitated a reexamination of its store format, target customer base, and approach to human capital.

In essence, this the story of how two INSEAD MBA students had a great idea for an integrated service to take over companies' product return streams and how they turned this idea into a successful business. Cycleon was founded in 2005 to offer original equipment manufacturers an option to manage returns at a lower cost than was offered by express services, and with greater speed than possible by leveraging forward supply chain partners. It describes the reverse logistics market, Cycleon's strategic positioning, and the entrepreneurial challenges it faced.
