Nonprofits do not always have the resources to hire a professional evaluator. This article discusses how the data you do have—whether anecdotal, subjective, interpretive, or quantitative—can be used effectively to measure and reach your goals. With the use of case study scenarios, the authors demonstrate that even “imperfect” metrics can still provide the context that is needed to help audiences understand the scope and progress of your project. Emphasis is placed on the importance of working relationships with partners and other relevant players in order to to build a common understanding and trust in the data collection and measurement methods employed.
