What is a baseline schedule?

A baseline schedule serves as a key project management tool that encompasses the original approved project timeline. It is utilized as a reference point to measure and manage project performance throughout its execution. By establishing a baseline schedule, project managers can track progress against the initial plan, assess any deviations, and analyze how changes affect the overall timeline.

This concept is central to project management because it allows for assessing variances and ensuring that the project adheres to its planned schedule. When there are discussions about project delays or accelerations, having a baseline schedule enables teams to have informed conversations based on established commitments rather than vague assumptions. This maintainability and accountability are crucial for successful project delivery.

While the other options contain elements related to project scheduling, they do not encapsulate the specific definition and purpose of a baseline schedule as thoroughly. For example, the initial project timeline approved before work begins refers to the initial planning stage, rather than the ongoing reference point. A breakdown of tasks and milestones focuses on the detailed scheduling rather than the overall timeline, and a contingency plan, though useful, serves a different role in project management by addressing potential adjustments rather than establishing a benchmark for tracking progress.
