Most enterprise engineering programmes have a PMO. A QA function. An architecture review board.

What most are missing is a function that asks the uncomfortable questions none of those roles are designed to ask:

Is the architecture coherent at programme scale, not just sprint scale? Are our delivery signals telling us the truth? Do we have risks that nobody has named yet? Is the value we promised actually traceable to the work we are doing?

That function is called Technical Value Assurance. And its absence is one of the most reliable predictors of expensive programme outcomes.

I wrote about what it means in practice, across four dimensions: architecture oversight, delivery predictability, quality signals, and systemic risk management.
