What is the Schedule Baseline used for in project execution?

• A. To compare actual progress against planned dates and compute variances; changes require formal change control.
• B. To authorize the total project budget and approve resource allocation.
• C. To document risk responses and contingency reserves.
• D. To define quality metrics and acceptance criteria for deliverables.

Answer: (A)

The Schedule Baseline is the approved, time-based version of the project schedule that serves as the reference for measuring progress during execution. By locking in this baseline, you have a fixed plan to compare actual work against, which lets you calculate schedule variances and assess schedule performance. If actual progress diverges from the baseline, you can determine the impact, decide on corrective actions, and, if needed, bring any changes through formal change control to rebaseline with stakeholder approval. This baseline works with the cost baseline as part of the overall performance measurement approach, and it supports earned value analysis to forecast completion dates and manage schedule risk. The other aspects mentioned—budget authorization, documenting risk responses, and defining quality metrics—belong to separate baselines or plans, not the schedule baseline.
