An agile product roadmap is a strategic document used in agile development that outlines the vision, direction, and goals for software development over time. Unlike traditional, fixed roadmaps, agile roadmaps are flexible and adaptable, allowing for changes based on feedback and evolving priorities. They focus on delivering value to users in small, incremental releases, with a strong emphasis on collaboration, feedback, and continuous improvement. Agile product roadmaps can be especially helpful for startups and product teams building something from scratch as they allow for flexibility and changes that customer feedback may help inform, and they don't restrict the development based solely on assumptions or deadlines.
