Roadmaps are commitment devices, not prediction tools.

Roadmaps are commitment devices, not prediction tools. The value isn't in being right about Q3 — it's in forcing the trade-off conversation before the pressure of the deadline does it for you.

Every roadmap review I've run that actually changed a decision did it in the room, not on the slide. The document is just the excuse to get everyone looking at the same trade-off at the same time.

If your roadmap never gets argued with, it's not doing its job.
