Fewer boards is not necessarily a good thing unless more decision-making and therefore control of resources is cascaded down. Considering that the decision on overseas travel now rests at 2* for the next 4 years, I'm not hopeful that this proposal would work.
Project management vested in one person effectively exists now with SROs and any proposal would have to be compliant with the NAO; the problem is that previous reviews of procurement have tried to compare us with, say, the NHS or with the private sector - neither of which is a just comparison.
