Evaluation is a distinct process, different from reporting to all stakeholders. While reporting is largely an administrative task focused on accountability, evaluation is a strategic process focused on improvement. The evaluation process allows nonprofits and philanthropies to increase the effectiveness and efficiency of their mission achievement. Each organization should use evaluation to measure the impact of actions, assess how those actions align with missions, and act upon this information. As entities that serve the public, nonprofits and philanthropies have an obligation to demonstrate their value to the public good. The public has a stake in charitable performance and is entitled to information regarding an organization’s results. Nonprofits and philanthropies should regularly measure their performance against a clear set of desired outcomes and should share such information with their diverse constituents.
