According to the PMBOK® Guide, the process of monitoring the status of the project to update project progress and manage changes to the schedule baseline is the formal definition of Control Schedule.

Core Objective: This process is concerned with determining the current status of the project schedule, influencing the factors that create schedule changes, determining if the project schedule has changed, and managing the actual changes as they occur.

Schedule Baseline: The schedule baseline is the approved version of a schedule model that can be changed only through formal change control procedures and is used as a basis for comparison to actual results. Control Schedule is the mechanism used to protect this baseline from unauthorized deviations.

Key Activities:

Comparing actual work performance (start and finish dates) against the baseline.

Using Earned Value Management (EVM) metrics like Schedule Variance (SV) and Schedule Performance Index (SPI) to quantify delays.

Performing Trend Analysis to see if performance is improving or deteriorating over time.

Determining if corrective or preventive actions are needed to bring the project back in line with the plan.

Comparison with Other Options:

Quality Control (B): This process (now Control Quality) focuses on monitoring and recording results of executing the quality activities to assess performance and recommend necessary changes to the product or deliverables, not the timeline.

Perform Integrated Change Control (C): This is the overarching process where change requests are reviewed, approved, or rejected. While it manages changes, it does so for the entire project (Scope, Cost, Schedule, etc.), whereas the specific monitoring of the schedule progress happens within Control Schedule.

Develop Schedule (D): This is a planning process. It involves analyzing activity sequences, durations, and resource requirements to create the schedule model; it does not monitor progress once work has begun.
