The authors assess the special opportunity of several stakeholders—including the nonprofit board, foundations, and the national office of multisite nonprofits—to create a new culture that values organizational performance. For the nonprofit manager trying to build an organization that is truly responsive to its clients and community, High Performance Nonprofit Organizations is an essential review of best practices. For the board member, foundation program officer, or nonprofit leader trying to create sustained impact, it is a provocative challenge to deal with the sector’s unfinished business with a new approach.
