A roadmap is a visual representation of a plan or strategy that outlines the key steps, goals, and milestones to be achieved over a specific period. It provides a clear overview of the path to reach a desired destination or complete a project. Roadmaps help in setting priorities, communicating objectives, and aligning team members towards a common vision. They can be used in various contexts, such as product development, project management, or business strategy, to guide decision-making and track progress towards goals.
