Project Baseline and EVMS Performance – Variances Effective Communication

As a project manager, you are always looking for ways to improve your project’s performance. One way to do this is by establishing a project baseline and using Earned Value Management System (EVMS) to track your project’s progress. In this article, we will discuss what project baseline and EVMS are, their benefits, and how to use them to improve your project’s performance.

What is a Project Baseline?

A project baseline is a snapshot of your project’s scope, schedule, and budget at a particular point in time. It serves as a reference point for comparing the actual performance of your project against what was planned. A project baseline typically includes the following:

  • Scope statement: A description of the project’s objectives, deliverables, and requirements.
  • Schedule baseline: A detailed schedule that shows the planned start and end dates of each task or activity, dependencies, and critical path.
  • Cost baseline: A budget that shows the planned cost of each task or activity, including direct and indirect costs.

By establishing a project baseline, you can measure your project’s progress and determine whether it is on track, behind schedule, or ahead of schedule. It also helps you to identify potential issues and risks early, so you can take corrective measures to keep your project on track.

What is Earned Value Management System (EVMS)?

Earned Value Management System (EVMS) is a project management technique that integrates project scope, schedule, and cost objectives. It measures the project’s progress in terms of earned value, which represents the value of the work completed to date. EVMS provides a comprehensive and objective analysis of your project’s performance by comparing the planned value (PV), actual cost (AC), and earned value (EV) of your project.

Using EVMS, you can monitor your project’s performance against the project baseline and make informed decisions about corrective actions. EVMS provides you with the following benefits:

  • Improved project control: EVMS allows you to track your project’s progress in real-time and identify potential issues early, so you can take corrective action.
  • Better decision-making: EVMS provides you with accurate and objective data that you can use to make informed decisions about your project.
  • Increased accountability: EVMS assigns responsibility for each task or activity to specific individuals or teams, which helps to increase accountability and improve performance.

How to Use Project Baseline and EVMS to Improve Your Project’s Performance

To use project baseline and EVMS to improve your project’s performance, follow these steps:

  1. Establish a project baseline: Create a project baseline that includes a scope statement, schedule baseline, and cost baseline. Make sure to get buy-in from all stakeholders before finalizing the baseline.
  2. Define the EVMS metrics: Identify the EVMS metrics that you will use to measure your project’s performance. These include planned value (PV), actual cost (AC), earned value (EV), schedule variance (SV), cost variance (CV), and estimate at completion (EAC).
  3. Collect data: Collect data on the actual performance of your project, including the actual cost, the percentage of work completed, and the schedule performance.
  4. Calculate the EVMS metrics: Calculate the EVMS metrics using the data collected in step 3. This will provide you with a comprehensive and objective analysis of your project’s performance.
  5. Analyze the results: Analyze the EVMS metrics to determine whether your project is on track, behind schedule, or ahead of schedule. Identify potential issues and risks early, so you can take corrective measures to keep your project on track.
  6. Take corrective action: Take corrective action to address any issues or risks identified in step 5. This may involve adjusting the schedule, revising the scope, or reallocating resources.
  7. Monitor progress: Monitor your project’s progress using the EVMS metrics and adjust your project plan as needed to keep your project on track.

Effective Communication of Cost and Schedule Variances

When communicating variances to stakeholders, a project manager should employ the following best practices:

  1. Transparency: Always clearly communicate the project’s status and be honest about any deviations or variances from the baseline.
  2. Data and Evidence: Support your explanations with data from your project management tools. Visual presentations such as EVMS calculations, graphs, or charts simplify variances for stakeholders.
  3. Explaining Causes: Variances are not spontaneous. Identify and elucidate the root causes that led to these variances, which could be unforeseen circumstances, internal errors, or changes in scope.
  4. Discussing Impact: Discuss how variances influence project objectives, timeline, and budget. If risks associate with variances, highlight them.
  5. Propose Corrective Actions: After explaining the variance and its impact, propose corrective actions to mitigate the issues and discuss plans to steer the project back on track.
  6. Encourage Dialogue: Allow stakeholders to ask questions and engage in discussions. This encourages collaboration and provides valuable insights.
  7. Keep Stakeholders Informed: Regularly update stakeholders on how variances are being addressed. Don’t wait until the next scheduled meeting.
  8. Document Lessons Learned: Variances offer learning opportunities. Document these experiences to improve future projects.


Project baselines and EVMS are instrumental tools in enhancing your project’s performance. By developing a project baseline and employing EVMS to assess progress, you can anticipate potential issues and risks early, make informed decisions on corrective actions, and ensure your project stays on course. Implement the steps outlined above to incorporate project baseline and EVMS into your project management process and elevate your project’s performance to a new height.

Effective communication of cost and schedule variances is just as vital to a project’s success. Transparency, data-driven explanations, encouraging dialogue, and regularly updating stakeholders are essential practices. The ultimate goal is not only to explain variances but also to offer context, identify potential impacts, and suggest corrective actions. Following these principles won’t just showcase your competence as a project manager, it will also cultivate trust among stakeholders.

In the world of project management, continuous improvement is paramount. Embracing tools like project baselines and EVMS, along with effective communication practices, can undoubtedly enhance your capabilities and lead your projects to success.
