Periodically, the Rockefeller Foundation engages in an examination of concepts that cut across all grantees, such as efficiency, effectiveness, and organizational capacity. AID was developed after a periodic review identified innovation as a central theme. The Foundation then conducted a survey of the innovation literature and concluded that the private sector had used open and user-generated innovation with positive results. These innovation models were also consistent with general trends Rockefeller had observed in their grant-making: increasing globalization and interconnectedness, technology that enables inexpensive communication, and partnerships involving the public, private and nonprofit sectors. While some nonprofit organizations have adopted these models, usage was relatively uncommon, and Rockefeller decided to test and scale up these models in the development sector. The Foundation looks for opportunities to apply innovation models that were developed to address business or technology needs to social and development problems, where the models have not yet been proven.
