Effective investment in digital technologies and data is critical for improving public services and institutional efficiency. As public sector spending on digital technologies grows, governments must ensure these investments are managed well to maximise value and avoid inefficiencies. Applying agile investment strategies, balancing internal capabilities with strategic partnerships, and aligning budgeting with modern digital needs are essential for success. This paper presents the OECD Digital Government Investments Framework, offering guidance for strengthening governance, managing risks, and promoting result-oriented investments. By adopting a strategic, whole-of-government approach, policymakers can drive sustainable digital transformation and ensure efficient public expenditure on government technology.
