The Vital Role of project baseline in project management

A clear project baseline is the foundation of successful project management. This article explains what a project baseline is, why it is so important, and how to create an effective baseline for your next project.

What is a project baseline and why does every project need one?

A project baseline is the approved version of the original project plan. It includes the scope baseline, schedule baseline, and cost baseline. The scope baseline is the approved version of the scope statement, documenting what work is included and excluded from the project. The schedule baseline includes project milestones and task durations, while the cost baseline sets the project budget. 

Together, these baselines form the project performance measurement baseline. This sets the expectations for the project and is used later to assess progress. Without a baseline, you have no way to determine if the project is on track, behind schedule, or over budget. project baseline provides that visibility so the project manager can identify issues early and make course corrections.

What are the key elements of an effective project baseline?

An effective baseline has four key elements:

Clear Scope Definition: The scope baseline documents what is included in the project. All stakeholders must agree on what is in scope before finalizing the baseline. Changes often occur later, but you need an approved scope baseline as your starting point.

Realistic Schedule: The schedule should include all project tasks, logical task sequences, assigned resources, and realistic durations based on team capacity. Padding the schedule with fluff time sets the project up for failure when things take longer than planned.

Accurate Cost Estimates: Cost estimates should include labor, materials, equipment, travel expenses, software licenses, training, and all project elements. Inaccurate estimates obscure whether the project is truly over or under budget later on.

Formal Approval: The project manager presents the proposed baseline to stakeholders and formally secures their sign-off and approval for scope, schedule, and cost expectations before finalizing it. Lacking approval, the baseline lacks authority when monitoring performance later.

How do you create an effective project baseline?

Follow these steps to create an effective project baseline:

1. Document project goal, requirements, scope, risks, assumptions. Get all key information needed to plan the project upfront.

2. Break down the project work. Decompose deliverables into smaller work packages.

3. Estimate task durations with the project team. Those doing the work provide task duration estimates.

4. Sequence project tasks. Determine predecessors and successors to define task logic.

5. Assign resources and finalize schedule. Match tasks with people and finalize the project schedule.

6. Develop cost estimates. Estimate all costs including labor, vendor contracts, materials, equipment, travel, etc.

7. Secure approvals. Present the scope, schedule and budget to sponsors and stakeholders. Secure their formal sign-off on the baseline.

8. Baseline the project schedule. Mark the project schedule as the Baseline in your project management software once approved.

9. Manage changes to baselined work. Use your change management process for any requests to alter the approved baseline.

How does a baseline help you manage projects?

A clear project baseline helps you in many ways:

• It sets clear goals, expectations, budget limits and completion dates right from the start.

• It provides the approved standard to measure against so you can assess performance.

• It enables early identification of issues. Comparing progress to the baseline quickly shows when projects are behind schedule or over budget.

• It improves accountability with an authorized plan.

• It facilitates analysis of project trends so you can course correct early when projects goes off-track.

• It reduces confusion from scope creep with an approved scope baseline for reference.

• It streamlines change management since you can quantify requested changes against the baseline

In summary, the key benefits of an effective baseline are better visibility, accountability, performance measurement and control for the project manager.

What types of project baselines exist?

There are a few types of baselines in project management:

Plan Baseline: This is the initial approved project plan, including the scope, schedule and cost baselines detailed earlier.

Execution Baseline: If the initial plan baseline becomes outdated, you set a new baseline once execution begins. This second baseline matches current scope, staffing, schedule and budget expectations.

Forecast Baseline: As project assumptions change over longer projects, periodic re-planning often establishes an updated forecast baseline with an improved schedule and cost estimate. 

Tracking Baselines: Some organizations snapshot schedule status at certain intervals as distinct tracking baselines. This shows variance against each prior status point rather than only against the original plan.

How often should you change or update a project baseline?

Ideally, a baseline should not change once established. It sets scope, schedule and costs expectations so you can objectively measure performance later. However, major changes can require a new baseline, including:

• Significant scope changes: A big scope change requires re-planning the project and updating the baseline.

• schedule delays: If the schedule slips more than 10-15%, a new baseline would portray a more realistic timeline.

• cost increases: Similarly, a 10-15% budget overrun warrants a revised baseline for the added costs.

• staffing changes: Losing core project staff would alter the schedule and require a new baseline calibrated to the team.

Aside from major changes, you should not alter the baseline simply because projects are behind schedule or over budget. The value of the baseline is objectively showing those deviations so you can correct them.

Can a baseline ever be changed or updated?

Sometimes a baseline change is warranted, but it should go through formal change control. Reasons to change an approved baseline include:

External changes: Market changes, new technologies or change in business priorities can require re-planning the project's approach and baseline.

Better accuracy: As the project progresses, we gain clearer insight on work complexities, task durations and costs. An updated baseline may portray a more precise picture.

Beyond planned contingency: If execution challenges and risks exhaust the contingency time and budget built into the baseline, additions may be needed in the plan. 

Approaching milestones: Periodic baseline updates as key milestones approach can ensure projects complete within targets.

Value improvement: Continuous improvement initiatives might identify ways to deliver increased scope or superior quality without increasing cost or schedule.

Any baseline changes should go through rigorous change control though. The project manager presents a change request with the justification, proposal and impact assessment. Once sponsors approve the changes, they reset and re-approve a new project baseline.

How do software tools help with managing project baselines?

project management software like MS Project, Primavera P6 and Planview make it easier to set, visualize, and manage project baselines. Common capabilities include:

Set multiple baselines: Snaphot the schedule at any point to save a baseline for comparison later

Visual indicators: See if tasks start/finish before or after the baseline date

Cost/schedule variance: Quantify behind or ahead of baseline targets

Earned Value metrics: Combine baseline with actuals to measure cost & schedule performance  

Version control: Store and retrieve prior baseline versions

Baseline change logs: Records details like justification and approval for each baseline update

What problems can occur without a clear project baseline?

Many project managers neglect creating a formal baseline. But without one, some common issues include:

No basis for performance measurement: You lose the benchmark to assess if projects are on track, behind or over-budget.

Scope creep: Uncontrolled changes get introduced without a clear approval process and scope baseline for reference.

Poor accountability: Team members can blame others for performance issues since no target documented their assignments.  

Limited planning: Insufficient planning and estimating up front can lead to padded schedules lacking urgency.

In summary, without a solid project baseline signed-off by sponsors, project managers lack the key mechanism to control project delivery. Thus performance problems inevitably start emerging.

Takeaways and Conclusion

Here are the key takeaways from our overview on project baselines:

• A project baseline sets scope, schedule and budget expectations, acting as your performance measurement benchmark.

• An effective baseline starts with detailed project planning, accurate estimates, and formal sponsor approval.

• Always baseline your project schedule in software once the initial plan is complete.

• Compare subsequent progress against the baselines to assess performance.

• Only change baselines through formal change control when warranted by major changes.

In closing, every project manager should invest time upfront creating a thoughtful project baseline and securing sponsor sign-off on it. This single deliverable enables control, accountability, visibility and performance measurement vital for project success. While it takes work to maintain baselines, that effort pays dividends over the project lifecycle.
