Government & PPP
For government and PPP programme offices reviewing sponsor-submitted models
The problem
- PPP and concession models are typically submitted by the sponsor, not built in-house — the reviewing authority did not construct the model it is being asked to rely on.
- A structural error in a submitted model can misstate exactly the figures (availability payments, whole-life cost comparisons) a public decision is being made on.
- Programme offices are accountable to public scrutiny in a way that makes an undocumented or unverifiable review process a governance risk in itself.
In practice
A deterministic, evidenced structural check gives a programme office a defensible, repeatable basis for its own review file.
