I agree with this. When we held our annual conference last year, we had a session on project management. It was super packed and we had a ton of questions.
What was most interesting was that probably 1/3 of project management questions were from folks not traditionally in my mind were project managers. These were folks managing a grant project, a communication project, or a very specific mission project. Not the traditional IT/systems type projects we think of.
But the same questions applied which were a lot about leadership, budget, scope, managing up, managing vendors and outside parties, etc
