A product roadmap outlines the vision, strategy, and planned features of a product throughout its development lifecycle. It serves as a communication tool that aligns stakeholders, guiding the development team on priorities and timelines. The roadmap typically includes timelines for releases, major milestones, and key objectives, which helps ensure that everyone involved is on the same page. Effectively using a product roadmap allows organizations to manage expectations, optimize resources, and respond to market dynamics with agility.
