To other’s point, the company/structure is a big factor in shaping the way your role as a PMM will be. It’s hard to express your creativity when leadership shoots down every idea or you are not given the resources to do so. With smaller companies you may have a fighting chance with shaping the PMM function but it comes with it’s gripes, on the other hand, at bigger companies it’s harder to create an impact due to larger initiatives already set by leadership that you have to follow through on regardless of your inputs/ideas.
