Independent programme assurance · AI governance

Everyone says the programme is ready. Someone has to be sure.

I independently challenge the evidence behind critical readiness decisions for government and other consequential organisations, so leaders know what is proven, what remains uncertain and what needs to change before they commit.

The executive risk

The cost is rarely the problem. It is finding it late.

Dashboards, stage gates and status reports can all be green while important assumptions remain untested.

Once commitments harden into dates and public expectations, choices narrow and the cost of correction rises.

Find it while you still have choices

I challenge readiness evidence before weaknesses become rework, delay or failed implementation.

Know what the evidence can support

Separate demonstrated readiness from assumption, expose material gaps and establish whether the decision has a defensible basis.

Protect the investment

Earlier challenge preserves options, reduces avoidable disruption and protects the value the programme was meant to create.

Independent challenge

Confidence is not the same as assurance.

At 31 March 2026, the Government Major Projects Portfolio contained 189 projects with a combined whole life cost of £924.2 billion.

29 were rated Green, 109 Amber and 34 Red, with a further 17 exempt from a published delivery confidence rating.

Senior Responsible Owners provide NISTA with an updated delivery confidence rating each quarter. Where a project received active NISTA support or independent NISTA assurance within the previous six months, NISTA supplied an independent rating instead. Otherwise, the published rating was the SRO's self-reported assessment. Government guidance makes the SRO accountable for the project's success.

What makes the work different

I came to AI governance from the testing floor.

Does it actually work?

For more than two decades, my work has started with that question. Long before AI governance became an executive concern, I was testing complex systems where assumptions could not substitute for evidence.

I bring the same discipline to programme readiness and AI governance today: testing not just whether technology works, but whether the confidence placed in it is justified.
