Rick Moyers, writing in the Chronicle of Philanthropy, says in the wake of NPR President Vivian Schiller’s resignation, the NPR Board needs to ask itself two questions: Are we clear about our mission? And, given our mission, do we have the right board? “All nonprofit organizations need different boards at different stages of their growth and development and need clarity about their missions,” Moyers writes. “Failure to answer these questions head-on leads to organizations that are hard to govern and difficult to lead. Just ask Vivian Schiller.” Moyers is vice president of programs and communications at the Eugene and Agnes E. Meyer Foundation in Washington, and co-author of A Snapshot of America’s Nonprofit Boards.
