The efficient management of government finances and treasury departments is essential for a nation’s economic performance, and especially for developing nations as they seek to transform from a traditional economy to a more advanced and globally competitive one. This transformation must be successful and sustainable into the future. This case looks at how sustainability was driven by streamlining government operations and processes in an Indian State. Inputs have been drawn from the Directorate of Finance and Treasuries and its Treasury Management System project implementation team. Successfully implementing such a project is not enough in itself; it should also be sustainable in the long run, enabling decision-makers to anticipate and tackle future challenges. The case allows students to gain a better understanding of such projects and how policymakers can and should design implementation strategies proactively. The case brings triple bottom line analysis and environmental considerations into public-sector finance service provision.
