I came up with the below around 20 years ago when I was first exposed to tech-teachers (outside Uni) and auditors (work) (I blame it on reading too much Dilbert)(I am aware that the 1,2 are common, I thought of 3,4 at the time)(I wouldn't be surprised if 3 is common)(but 4 is definitely mine)(I honestly believe I came up with 3,4 - it was 20 years ago so apologies if I remember that wrong). 1) Those who can, do. 2) Those you can't do, manage. (partially "Peter Principle" imho) 3) Those who can't (even) manage, teach. 4) Those who can' (even) teach, audit.
