In the scale of brokenness, how broken will the proposed regime be after say five years following implementation? The existing system is broken but not irredeemably so. Perhaps like a broken car all it needs is the replacement of a few parts to achieve the objective of getting it to drive safely and efficiently.
I note that the good Dame lauds CDM in her Report as a model to structure accountability. CDM is something I deal with daily and it is broken, not as broken as the version that preceded it but broken nonetheless. However, it remains a good, broken, vehicle and a few tweaks here and there should keep it bumping along.
I am always wary of folk who want to wipe the slate clean. That is the easy option. In terms of objective, there is not a great deal of difference between an old Ford Escort and a new Rolls Royce if they are both broken, other than it might be cheaper to fix and maintain the former!
