A product launch plan is a crucial document that outlines the tasks and timelines involved in introducing a new product or feature to users. It helps identify goals, strategize, and assign responsibilities across teams. To create an effective product launch plan, start with customer research, set actionable goals for each phase, visualize your launch on a timeline, define roles and responsibilities, use checklists, and maintain flexibility in the plan. A well-structured roadmap can ensure that everyone is aligned around a single source of truth during the launch process.
