They only need to learn a few things:

How to count

and, the meaning of ........morality, ethics, resposibility and accountability.

I thought Cranfield University already did this?.

Its not enough to handle project management with civil servants just put on courses.
A specialized experience of production methods and related sciences is essential.

The trouble has long been in the Civil Service that too many qualified industrial specialist people have been made redundant, especially in the MoD, in favour of 'Admin' people', which is what it is too top heavy with now.

So, its going to be the same old people applying for these posts, leading to the same old mistakes in detailing with industry, because they have no practical experience from the shop floor upwards which takes years, not a course of a few weeks. Politicians keep making these decision mistakes for the same reasons.

nothing like a man in the middle who does not have to make decisions, never looks bad in any decision, and get a very good public sector pension and wage for basically doing nothing in there working life.

Sir Bob Kerslake might like to look at the NHS where administrators pay huge fees to "consultants" who know nothing of medicine, and who for their large fees produce unworkable schemes. I as a consultant anaesthetist had to sit through a presentation in which the management coondultant produced his plan to 'computorise' the hospital. He linked the outpatient department to the operatinge theatre 'module' so that patients could be be given in outpatient clinics an immediate appointment for their slot in the operating theatre module. He was very upset when I explained that it would not work because the limiting factor in getting patients in for opearations was not operating theatre time but shortage of beds. He was unaware that surgical patients need beds.
Properly qualified medical administers should not need to call in outside consultants for every proposed innovation. They should be able to do the job they are paid for. When I worked in a Cabadian Hospital the chief administrator was a highly qualified doctor with a Harvard MBA. He had the courage to go on television and tell the public how much a proposed and needed innovation would cost and the effect it might have on Provincial taxation. he did not pretend that that the new service would be funded from 'economies'.

The NHS needs administrators and managers like him.
