This three-month product roadmap timeline is the sole source of information about a product's progress. Roadmaps can be as simple or as complex as needed, but they must always be understandable and accessible to everyone involved in the product's development. A roadmap is a "single source of truth" that collects all product information from all teams involved in the development project. Individual sections may have their department-wide systems, but all of that information should also be stored in the product roadmap. As a result, everyone on the project can refer to the same source for up-to-date information.
