When your project manager tosses a bunch of vague suggestions your way, “ok this deck is easy, we start with the vision, then show the strategic buckets and mirror these against our core competencies”, and you don’t get it, it is not your problem.
Asking for explanations of everything might annoy her. Instead, ask for a quick example. “Which bucket for example?”, and “and can you mirror it against 1 core competence for me”?
This is like a small “Rosetta Stone” for you, you have decoded this particular case example, now you can take on the rest (and in the process write a presentation with fewer buzz words).
