Insufficient use is currently made of policy impact indicators to enable governments to effectively assess the impacts of their policy programmes on objectives of sustainable development. Attempts to develop systematic policy impact indicators have so far taken place mainly in North America and Europe, where more sophisticated management applications are found, and where the technological advances in software applications in the public sector have made such specialised foci possible and feasible. This paper contains a summary and assessment of the progress that has been made so far in the UN and selected other cases, as well as in South Africa to fill this gap and develop contextualised policy sustainability indicators for the measurement of good governance performance. These initiatives could also be customised for application in other (especially developing) countries.
