MMC slows down when teams assume approval can be worked out later.
By then, it is already too late.
If the building surveyor, engineer and consultants are not aligned on the inspection pathway before production, the project is carrying risk before it leaves the factory.
Not product risk.
System risk.
In MMC, approval is not paperwork after the fact.
It is part of the delivery design.
Approval must be designed and planned upfront.
If you discover it on the way, you are already late.
