I'd be less concerned about tinkering with IOT where we train our junior officers for dealing with the foundational stages of their first couple of tours, and more concerned with our major failure to educate more senior personnel at senior flt lt upwards.
What you pick up in IOT should be a building block for the first few years, nothing more. But I think we're really patchy at the higher level concepts and thinking. I came through the ISS / JOCC route, so don't know what JOD is like these days, but ICSC was more about jumping through hoops and 'hitting the pink' than it was about real thinking and intellectual rigour. And given the relative difficulty of getting an ACSC slot, that's a lot of individuals going about their business, often representing the RAF and UK in a wider environment, who are relying on their own knowledge and experience to get the job done unsupported by academic or conceptual education.
We put the onus too much individuals to use ELCs, become autodidacts, without necessarily harnessing it or giving them the support, time and space to do it. And you can't just flick a switch to turn on that sort of thinking, it has to be developed over time, with individuals able to observe and understand the world they are operating in, and their place and role with in it. That's what will bite us in the arse in the longer term, a lack of strategic appreciation and higher level thinking not a couple of extra months at Cranwell.
