A project schedule defines the process and establishes a timeline to be followed in delivering the project. Avoiding schedule slippage is a key objective of schedule management. Comprehensive project schedules will identify all of the project's stages, phases, and activities assigned to each team member mapping them to a timeline that measures key milestones (dates) that are used to keep track of work progress.

Schedule management interfaces directly with scope, cost, and quality management when team member roles and activities are defined, coordinated, and continually monitored.
