CPM Schedule Vs Baseline Schedule : What Is The Difference?

You are provided with the crucial distinctions between a CPM schedule and a baseline schedule. Undoubtedly, the principal dissimilarities between these two project management scheduling approaches are noteworthy. The key variances between the two scheduling methods comprise of:

  • The rigidity or flexibility of the schedules
  • The textual or visual representation of the schedules
  • The degree of participation of diverse project contributors in schedule formulation and adherence
  • The effectiveness of each scheduling approach in intricate projects.

CPM Schedule and Baseline Schedule : Understanding The Difference

Project management employs two primary types of schedules: the baseline schedule and the CPM schedule. The baseline schedule is often viewed as the conventional approach in industries such as manufacturing or construction, while the CPM schedule is considered a newer concept. However, the CPM schedule was actually developed back in the 1950s, making it an established project management methodology.

It is crucial to comprehend the fundamental definitions of these two scheduling techniques to appreciate the significant differences between a baseline and a CPM schedule.

What Is Baseline Schedule In Project Management?

In project management, a baseline schedule represents a fixed project timeline that is often referred to as a “frozen” schedule. It is used to monitor project progress, track contract milestones, and ensure adherence to the budget. The baseline schedule provides stakeholders with a clear understanding of the project timeline.

As a fixed schedule, it is compared with the actual project progress. When any deviation from the original baseline occurs, relevant project stakeholders are notified and required to take appropriate action, such as making modifications to the project.

If significant changes to the project’s scope are required, the original baseline schedule becomes outdated and must be replaced with a new one.

What Is CPM Schedule In Project Management?

A CPM (Critical Path Method) schedule differs from a baseline schedule in that it is not a fixed timeline. Rather, it is designed to be adaptable, allowing for adjustments to ensure the project stays on track and on schedule.

In addition to informing stakeholders of project progress, milestones, and projected completion dates, a CPM schedule involves all stakeholders in its development. This means that all anticipated activities of project contributors, including contractors, subcontractors, project owners, vendors, and suppliers, are incorporated into the schedule. This collaborative approach ensures that all stakeholders have a shared understanding of the project schedule and can contribute to its successful completion.

What Is The Major Difference Between CPM Schedule And Baseline Schedule?

The primary difference between a baseline schedule and a CPM (Critical Path Method) schedule lies in stakeholder participation and accountability. In a baseline schedule, only a select group of individuals associated with the project are responsible for creating the schedule. While they may consult stakeholders for basic timing information, stakeholder interaction and input are limited.

In contrast, a CPM schedule involves active participation from all primary stakeholders, who collaborate to develop a graphic timeline. They prepare time projections for milestone accomplishments and plan how the schedule can be adapted to address any unexpected issues that may arise during the project.

Overall, the CPM schedule appears to be better suited for complex projects, particularly in the construction and manufacturing industries.
