If you ask any one of your team what it is you do they will almost invariably tell you “project management.”
And then, in so many words, describe what you do on a daily basis in terms of the tasks you undertake, the processes you go through, and maybe some snide comments about “buggered if I know. Answer emails? Right?”
If you want to really get your team to understand what it is you do, tell them you’re in “risk management.”
Because after all, what is project management but the clever managing of risks, some known, many unknown.
Good project management is like insurance against catastrophe.
