Public Sector Finance Management for a National Government
Interval strengthened financial governance, operational transparency and scalability for a rapidly expanding government programme portfolio. By establishing a dedicated finance management function and introducing improved controls and reporting standards, we helped the department transition from reactive processes to a stable, scalable and future-ready operating model.
Background
A national government department was experiencing significant growth across its international project delivery portfolio. As programmes expanded, existing finance tools and processes could no longer support the increasing volume of activity.The department required stronger governance, clearer reporting, improved cross-department coordination and a scalable financial framework capable of supporting automation and long-term expansion.
The Challenge
The department faced several operational and structural constraints:
Legacy finance processes unable to support rapid portfolio growth
Lack of dedicated financial governance for an expanding international delivery function
Inconsistent budgeting, procurement and payroll workflows
Limited transparency and reporting across departments, especially where spend was recharged
The need to introduce scalable systems and practices aligned to government standards
Our Solution
Interval established a dedicated Finance Management function tailored to the department’s needs. A highly qualified Finance Manager (ACCA, MSc Professional Accountancy) was deployed to work closely with PMO, procurement and senior departmental stakeholders.
