Measuring Results in Challenge Funds: Practical Guidelines for Implementing the DCED Standard
A implementation manual outlining an eight-part framework for measuring and managing the results of challenge funds. The manual advocates using IRIS metrics for aggregation and comparison across a portfolio (pages 18-19). Synthesizing the private sector development experiences of donors, foundations, and UN agencies, the guide's recommendations about impact measurement are applicable to many forms of private sector partnerships.
"Challenge fund managers can use IRIS to ensure that they are consistent with other impact investors, and as a source of inspiration when selecting indicators. They are particularly useful for setting common indicators, as each indicator has a clear definition designed to allow for aggregation. The use of the IRIS indicators may also help the business attract other impact investment capital."
