CASE STUDY · INVESTMENT ASSURANCE
South Yorkshire
Mayoral Combined Authority
Senior assurance leadership within a live investment environment covering transport, regeneration, economic development and skills.

The challenge.
The Authority needed senior assurance capacity to support robust investment decisions while maintaining a practical understanding of programme deliverability and the requirements placed on sponsoring teams.
The work required independent challenge alongside constructive support for the teams developing investment proposals, with a clear connection between appraisal requirements and the realities of implementation.
Our contribution.
- Leadership of the Assurance Team within the Authority’s investment environment
- Independent review and challenge of business cases
- Investment Board support and portfolio oversight
- A comprehensive review and rewrite of the Assurance Framework
- Connecting appraisal with governance, risk, readiness and deliverability
The value delivered.
The assignment provided senior assurance capacity and a revised framework to support consistent appraisal and informed investment decisions.
It demonstrates how Three Oaks combines sound professional judgement, independent challenge and a collaborative approach, helping sponsors and teams address material concerns without losing sight of delivery.
