shall stick my neck out here and say that I doubt if there is a single technical grade at AbbeyWood today who satisfies the "Grade Description" for his/her grade. Do the Services have a similar "Rank Description"? For example, the direct entrant grade in DE&S (C2, aka HPTO/HSO) is required to have demonstrated the ability to manage 200 staff. For a C1 that is 600. Similarly, a C2 avionic engineer is also required to have managed projects across all disciplines (software, radar, ELINT, nav etc), in every stage of the procurement cycle, before promotion to C1. Step forward anyone in DE&S who satisfies that criteria.
Citation needed for those statements please, because I can't find them. And more to the point, do such descriptions remain valid.....?
