Geoff - I do feel that if everyone stayed inside their remit then there's a risk that nothing would get done! Sometimes its the bigger picture that matters, using better tools or improving the process. Of course change is always a bit risky though!
Simon - do let me know if that support system ever gets replaced. I know they're still talking about it. Under the radar is probaly a better plan for things I know are important, and will contribute to team performance. Management sometimes come under so much pressure that they can't invest a little time to save a lot so forcing their hand can work well .... I won't be making a habit of it though, management are there for a reason and need to co-ordinate resources as best they can, I really don't subvert that on a regular basis.
