It has long been MoD policy not to trumpet or attempt to learn from procurement successes; of which there have been many.
The official line is that to do so would raise the bar and with it the expectations of both the Users (you) and our Masters (Government). Favourite phrases used to people who dare deliver to Time, Cost and Performance include;
1. "You are an embarrassment to the Department"
2. "You are tainted by your experience"
In both cases followed by "Find another job".
I'm sure everyone will have good fun with this thread, but the above is demonstrably true.
