This tailored impact evaluation methodology was developed in collaboration with the Government Transparency Institute.

The methodology provides references that show that roughly half of all fixed-capital investment by governments goes into public infrastructure – an essential driver of economic growth and social development, especially in developing countries. Yet, infrastructure projects frequently fall short of expectations, with mismanagement driving up prices and costs causing delays and yielding poor-quality assets that distort public spending.

These resources apply an adaptable and flexible approach that considers different countries’ context, including the institutional and legal environment. The methodology and guidance note can be used independently to support any national or sub-national region looking to make the business case and demonstrate clear benefits to institutions and funders for improving quality of data and implementing processes that encourage transparency.

The methodology covers vital components such as transparency, monitoring, impact in prices and quality, as well as a step-by-step guide that involves data mapping, data preparation, analysis, interpretation and reporting.
