In  2016, the Social Sector Accelerator, the innovation-focused subsidiary of Counterpart International, partnered with IO Sustainability to conduct a landscape analysis of existing research regarding the organizational and social impacts of capacity building. In the process, we reviewed research from nearly 60 academic, think-tank, and thought leader sources published after 1990. The research was not limited to those sources that explicitly reference “capacity building,” but instead included any materials related to strategies for strengthening non-profit organizations.
