Marketing your accomplishments is critical! It is epecially important to align leadership expectations with reality since product marketing roles and responsiblities can vary greatly from business to business or even across products/BUs.
My team and I address this in a few ways. First, we share quarterly email updates with a broad distribution list. These emails include our topline priorities, related initiatives, shoutouts to our key stakeholders (since most of what we do is collaborative), learnings and pivots, as well as a link to an archive doc with all of our previous updates for easy reference. I also ensure my direct leadership is aware of our goals and accomplishments so they can know what we're focused on and can speak up when given the opportunity in higher level meetings. Finally, not leadership specific, but we are active on team slack channels sharing key activities across sales, marketing, and product teams in real time.
