Not wishing to sound awkward, but the "oversight" procedures you speak of are laid down for existing similar "GOCO" contracts, although as alluded to before, MoD have chosen a new name this time to avoid having to admit they already have such procedures. In turn, this will ensure plenty of jobs are retained for expensive consultants who are employed to work out what to do, but of course aren't told it is already being carried out successfully. As happened with the so-called MoD Integration Authority some years ago.
The current procedures were the subject of a series of test cases in 2001/2, overseen in accordance with the procedures you ask about. I cannot publish what are probably Commercial-in-Confidence details here, mainly because MoD do not publicise them (for the reason stated above - it is too embarrassing to admit the solution is actually long standing policy). You should ask the aforesaid MIA, or his successor, about this. He refused to sanction the initiative until the name was changed to remove the word "Authority" from the body with "oversight" responsibility. That little paddy cost us 9 months, but it ate into the remaining time in his lucrative contract.
