Baseline

An officially approved snapshot of a work product that may be altered only through formal change control and serves as the benchmark for comparing plan versus actual results.

Key Points

  • Represents the approved, frozen reference version of the plan or deliverable.
  • Any change to it requires a documented change request and formal approval.
  • Used to measure variances and track performance against what was planned.
  • Common types include scope, schedule, and cost baselines, which together support performance measurement.

Example

The project schedule is approved and set as the schedule baseline on May 1. Two weeks later, a task slips by 5 days. The team reports a 5-day schedule variance against the baseline. To reflect an approved scope change that shifts dates, the PM submits a change request; only after approval is the schedule baseline updated.

PMP Example Question

During execution, an approved scope change causes the critical path to slip by 10 days. What should the project manager do to keep performance measurement accurate?

  1. Update the schedule and baseline immediately to match actuals.
  2. Submit a change request to update the schedule baseline through integrated change control.
  3. Re-baseline the entire project only after project closure.
  4. Do nothing; baselines should never be changed.

Correct Answer: B — Submit a formal change request to update the baseline

Explanation: Baselines can be modified only through formal change control after approval; this keeps comparisons of planned versus actual results valid.

Advanced Project Management — Measuring Project Performance

Move beyond guesswork and status reporting. This course helps you measure real progress, spot problems early, and make confident decisions using proven project performance techniques. If you manage complex projects and want clearer visibility and control, this course is built for you.

This is not abstract theory. You’ll work step by step through Earned Value Management (EVM), learning how cost, schedule, and scope come together to show true performance. You’ll build a solid foundation in EVM concepts, understand why formulas work, and learn how performance data actually supports leadership decisions.

You’ll master Work Breakdown Structures (WBS), control accounts, and budget baselines, then apply core EVM metrics like EAC, TCPI, and variance analysis. Through a detailed real-world example, you’ll forecast outcomes, analyze trends, and understand contingencies and management reserves with confidence.

Learn how experienced project managers monitor performance, communicate results clearly, and take corrective action before projects slip. With practical exercises and hands-on analysis, you’ll be ready to apply EVM immediately. Enroll now and start managing performance with clarity and control.
