This Compendium has been developed to address the challenge that FSD Network members face in the identification/design and application of indicators that measure financial market system changes and resultant FSD outcomes and impacts . As part of a broader effort to address the need for tools that support the practical application of impact oriented measurement (IOM) principles, the Compendium is aimed at serving as a resource with a bespoke set of quality indicators appropriate for FSDs to measure outcome and impact level results in a more harmonised manner.
