Yes; I agree. Surely it's all about the
mindset* of the "Noble Technician"** - the enquiring mind, the "hands-on imperative" and all such good stuff.

Although I must admit to having had the dubious pleasure in the past (and not just overseas) of being burdened with "technicians" who seemed to be prepared, shall we say, to simply rest on their laurels (not to mention their questionable, and generally over-inflated, "documentation").

No doubt most of us could suss out a wrong 'un within twenty minutes, without having to recourse to a search through their CPD (or any other) Portfolio.
