The schedule baseline is the approved version of the project schedule, which reflects the expected progress and serves as a benchmark for tracking actual performance.
Creating a schedule baseline starts with developing a detailed project schedule that includes all tasks, durations, dependencies, and allocated resources. Once this schedule is approved, it becomes the baseline that project managers use to compare actual progress against planned progress. This comparison helps identify deviations, delays, or variances that may require corrective actions.
Managing the schedule baseline involves controlling changes through a formal change control process. Any proposed modifications to the schedule must be thoroughly evaluated for their impact on the project's objectives. Approved changes result in updates to the baseline, ensuring it remains an accurate reference point. This practice maintains the integrity of the project plan and allows for effective monitoring and control.
Baseline Management is crucial for effective project control and decision-making. It provides a clear picture of the project's status relative to its original plan, facilitating performance measurement techniques like Earned Value Management (EVM). EVM relies on accurate baselines to calculate variances and performance indices, which inform stakeholders about the project's health.
By maintaining an up-to-date schedule baseline, project managers can communicate progress effectively, make informed decisions, and ensure the project stays aligned with its goals. It also helps in proactively identifying issues and implementing solutions before they escalate, thereby enhancing the likelihood of project success.
Baseline Management and Schedule Baselines Guide
Understanding Schedule Baselines and Baseline Management
Schedule baselines are foundational to effective project management, serving as the approved version of the project schedule that includes start dates, finish dates, and resource assignments. They represent the original plan plus any approved changes, becoming the standard against which project execution is measured.
Why Schedule Baselines Are Important:
1. Performance Measurement - Schedule baselines provide the reference point for measuring schedule performance.
2. Change Control - They create a formal process for evaluating and approving schedule modifications.
3. Stakeholder Expectations - Baselines help manage stakeholder expectations by clearly documenting agreed-upon delivery dates.
4. Historical Reference - They serve as historical data for future project planning.
2. Performance Measurement Baseline (PMB) - The integrated scope-schedule-cost baseline for measuring project performance.
3. Re-baselining Criteria - Understanding when re-baselining is appropriate versus when it may indicate poor planning.
4. Multiple Baselines - Maintaining original and current baselines to track evolution of the project plan.
5. Schedule Reserve - Contingency time built into the schedule to address known risks.
Exam Tips: Answering Questions on Baseline Management and Schedule Baselines
1. Remember the Purpose - When in doubt, recall that baselines exist to measure performance and control changes.
2. Identify Stakeholders - Questions may ask about who approves baseline changes (typically the Change Control Board or Project Sponsor).
3. Focus on Process - Understand the formal process for modifying baselines rather than making unauthorized adjustments.
4. Distinguish Variance Types - Know the difference between schedule variance, cost variance, and technical variance.
5. Recognize Inappropriate Practices - Be able to identify scenarios where baseline management is being misused (e.g., frequently changing baselines to hide poor performance).
6. Connect to Other Knowledge Areas - Understand how schedule baselines relate to scope, cost, risk, and quality management.
7. Apply EVM Concepts - Be familiar with Earned Value Management metrics that rely on schedule baselines (SV, SPI).
8. Look for Integration Points - Questions may test your understanding of how schedule baseline changes impact other project documents.
9. Time-phased Budgets - Understand that the schedule baseline includes time-phased budget information.
10. Change Impact Analysis - Be prepared to analyze how a proposed change might affect the baseline and project objectives.
By mastering these concepts, you'll be well-prepared to answer PMI-SP exam questions about schedule baselines and baseline management, demonstrating your understanding of these crucial project scheduling components.
