Being a product manager in an enterprise context is different. You finally align stakeholders on roadmap priorities, then marketing shifts campaign focus, finance changes budget priorities, and operations gets new leadership. You didn't lose alignment - alignment naturally drifts in complex organizations.

The best enterprise PMs I know maintain clear written strategy that articulates the why, what, and how. When priorities shift, they update it and reshare: "Here's what changed and why." A single source of truth lets stakeholders recalibrate fast without re-litigating everything in meetings.

Accept drift as the default state. Your competitive advantage isn't preventing it - it's making re-alignment fast.
