One thing that seriously hampers any progress is the MOD PTs inability to coordinate their own efforts. Each are in their own little stovepiped areas, unable to coordinate overall improvements. The exact same is true in the defence industry, and individual SMEs, working their own little area.
Very few managers out there, are able to manage complex systems like the MRA4, both from the MOD PT, or Defence industry. IMO of course, and I have some good evidence to back it up.
