The engagement included organisational restructuring, the introduction of risk-based management systems, improvements to audit selection processes, and the development of enhanced data and analytics capabilities within the national tax administration. The reform strengthened compliance management and improved the accuracy of revenue forecasting while reinforcing governance and operational efficiency within the tax authority. Capacity-building and systems integration measures supported long-term institutional sustainability and contributed to increased domestic revenue mobilisation and greater transparency in fiscal administration.

Technical assistance was provided for the formulation of a comprehensive Public Financial Management reform programme designed to strengthen fiscal governance and institutional capacity. The engagement involved developing a detailed intervention framework, programme budget, and results architecture aligned with national reform priorities and international public financial management standards. Analytical work included assessment of fiscal management systems, review of governance structures, and analysis of intergovernmental fiscal arrangements. Alternative implementation approaches were evaluated and financial analysis was conducted to ensure the programme design was feasible, results-oriented, and aligned with institutional capacity. The resulting framework provided a structured roadmap for improving fiscal transparency, strengthening public expenditure management, and enhancing accountability across government institutions.

An integrated programme of technical assistance and institutional capacity-building enabled the introduction of programme budgeting across central government agencies. The work included clarifying strategic objectives, aligning resources and activities with programme structures, training government officials, and expanding the national chart of accounts to incorporate programme classifications.

Countrywide analysis was carried out for government-owned and semi-government-owned healthcare facilities, alongside rigorous assessment of informal payments using large-scale beneficiary surveys. These analyses informed actionable recommendations to improve service delivery, reduce corruption, and strengthen accountability within the healthcare system.

Organizational restructuring and change management were combined with the introduction of system-wide risk-based management, strengthened audit selection and case-management processes, advanced analytics and data-mining tools, revised reporting standards, and standardized operating procedures.
