A go-to-market (GTM) plan covers everything beyond building: how a product or feature reaches users and succeeds in the market. A great feature with a poor launch underperforms — GTM ensures the right people know about it, can adopt it, and that the org is ready to support it.
Cross-functional by nature
✓ MARKETING → messaging, positioning, announcement
✓ SALES → enablement, pricing, who to sell to
✓ SUPPORT → trained and ready for questions/issues
✓ ENGINEERING → rollout plan, monitoring, kill switch
✓ LEGAL/COMPLIANCE → cleared if needed
GTM is the PM orchestrating many functions toward a coordinated moment — a hand-off failure here (e.g. support not warned) creates chaos at launch.
