lays out key elements that need to be considered in evaluating the net results achieved by these private actors. It uses case studies and analysis to show how to answer such questions as: Is it working? How do they and the public know they are doing good? And how to improve? Such questions are particularly important since little is known about the net results of private avenues for delivering public value. The contributors conclude that "doing good" organizations need to be more transparent and accountable regarding their operations and achievements. The book suggests perspectives on how better monitoring and evaluation systems can improve their accountability.
