A baseline schedule is derived from a schedule model to meet the project execution plan and achieve management approval for use as a baseline. A schedule model is a representation of the project activities, durations, dependencies, and resources that shows how the project will be executed over time. A baseline schedule is a specific version of the schedule model that is approved and frozen as a reference point for measuring and controlling the project progress and performance. A baseline schedule reflects the agreed-upon scope, cost, and schedule of the project and serves as a basis for comparison and change management. References: CBAP / CCBA Certified Business Analysis Study Guide, chapter 6, page 234; CBAP Sample Questions, question 252.
