No disrespect intended to Tcumsesh, but I think he is utterly wrong on this front. There may well, in the past, have been a requirement to demonstrate you could manage numbers of people, but if it was, it is dead, buried and no longer remotely relevant.
If it helps, I have never, ever, seen any hint of a personnel description of this sort in the last 15 years when it comes to discussing requirements for direct entry. I say this as someone who has a reasonable amount of experience sniffing round HR manuals on promotion and staffing issues.
