This study explores the management challenges in realising value for money from government digital transformation projects. The mission of such projects is to provide improved public services at greater levels of efficiency through digital transformation. Yet, the predominant perspective in the project management discipline is that project success is judged by the temporary project organisation’s efforts on the successful delivery of project outputs, with a relative lack of attention to how those outputs are transformed into outcomes for public service provision. In order to address this issue, we provide a content analysis and statistical validation of the UK National Audit Office's Value-for-Money reports addressing the 20-year experience of government digital transformation projects. The findings highlight the significance of integrating complex interface between systems, data and projects in the technological perspective and the management of benefits realisation in the organisational perspective that have been relatively marginalised themes in the extant literature.
