Product Manager
Last year I led a project to add Single Sign-On for our enterprise customers. It needed engineering, security, sales engineering, and customer success. None of those teams had worked together on a launch before. I started by getting one person from each function to draft a one-page definition of done together — what would be true on launch day. That document took two meetings to write and saved us from three different definitions of ready. I ran a Tuesday standup that lasted exactly fifteen minutes and required only blockers. Engineering shipped on time. Sales engineering had the demo environment ready a week early. Customer success migrated four pilot accounts in the first month. We closed two enterprise deals in the next quarter that had stalled on this exact missing feature. The thing that mattered was the shared definition of done. Without that, every function would have built its own version of the launch.
