Product Roadmap: The product roadmap provides a high-level view of the product’s development over time. It outlines major milestones, goals, and the overall vision for the product, which can be seen as a long-term schedule.
Sprint Backlog: The sprint backlog contains the specific tasks and user stories that the team commits to completing in a particular sprint. It provides a detailed plan for what the team will achieve in the short term, effectively serving as a schedule for that sprint.
Together, these artifacts give both a strategic and tactical view of the project’s progress, analogous to the traditional project schedule but adapted to the iterative and incremental nature of Scrum. Meanwhile, the product backlog is a prioritized list of all desired work on the project but does not directly equate to a schedule. The scrum board is a visual tool to track progress during a sprint but lacks the scheduling element of the roadmap.
