This reader presents the DCED Standard for results measurement and current thinking and practice related to its increasing adoption by programmes and use in varying contexts. The DCED Standard is a practical framework for private sector development programmes to monitor progress towards their objectives. It comprises eight elements: articulating the results chain, defining indicators of change, measuring changes in indicators, estimating attributable changes, capturing wider changes in the system or market, tracking programme costs, reporting results and managing the system for results measurement. The DCED also offers an optional, confidential ‘audit’ service, which can lend additional credibility to the results measurement system. This reader also provides insights in new sectors and contexts the Standard is being used within: management, business environment reform, challenge funds, financial services and in conflict-affected environments. FAQs and practical steps for involvement are included.
