I wish him luck
A while ago, I saw the HO for one of the forces (IT being managed by Capita; hmmm!) and I've seen first hand some of the problems that he will face.
The big problem is going to be to get the relevant buy in from the top down; and I'm not sure that will happen, as they all seem to be more concerned about maintaining their own little fiefdoms.
There's certainly major scope to generate efficiency and reduce bureaucracy; and with it, big savings and improved services. I really hope that he does well; but I won't be holding my breath.
