Timeline diagram - Project schedule
"In project management, a schedule is a listing of a project's milestones, activities, and deliverables, usually with intended start and finish dates. Those items are often estimated in terms of resource allocation, budget and duration, linked by dependencies and scheduled events. A schedule is commonly used in project planning and project portfolio management parts of project management. Elements on a schedule may be closely related to the Work Breakdown Structure (WBS) terminal elements, the Statement of work, or a Contract Data Requirements List." [Schedule (project management).
