International experience shows that performance-informed budgetary reforms are most effective when they are a part of a set of mutually supportive reforms, and not an isolated initiative. Efforts such as restructuring the budget around policy objectives and programmes, using performance information for decision-making, implementing spending reviews to examine baseline expenditure, and introducing IT systems mutually support the development of performance-oriented culture within the administration.
There is no one-size-fits-all design to performance-informed budgeting, as budgeting practices differ across countries. However, OECD experience shows that there are several key factors that can make the implementation of such reforms more effective. These include having clear and transparent objectives, encouraging both accountability and autonomy, and designing a practical and functional framework. These elements are essential for shaping a successful performance-informed budgeting framework tailored to each country's unique circumstances and needs.
While many OECD countries have been implementing performance-informed budgeting reforms, certain common challenges persist. As reported by OECD countries, this includes lack of political commitment, limited access to relevant performance data, insufficient capacities within line departments, and the absence of effective monitoring mechanisms. These challenges hinder the successful implementation of performance-informed budgeting, prompting countries to seek ongoing improvements to their frameworks to address these obstacles.
