Project's Roadmap is a document that organizes the whole project. Its purpose is to plan all the elements and stages of the project. Thanks to this, it is possible to estimate the time needed to design and program individual fragments.
The information contained in Project's Roadmap is a perfect starting point when creating project schedules. They allow to pre-estimate potential threats, milestones, and relationships between particular stages of the project.
During project works, Project Roadmap is a reference point that allows you to control your progress transparently. It also allows you to control whether work does not go beyond the planned scope of the entire project.
