Project management starts with a plan, one that is abstract until it’s executed. But project execution is blind without a way to measure progress and performance. You first need a project baseline in order to capture that plan and compare it to your actual progress. This allows you to see where you are.
Once you’ve set a baseline, there are many techniques that can help with performance management. Earned value management (EVM) is one such technique that, in a single integrated system, can accurately forecast problems so you can better manage project performance.
What Is Earned Value Management (EVM)?
As noted, EVM is a technique that project managers use to track the performance of their projects against project baselines. Often the progress of a project is thought of as ahead or behind schedule and over or under budget. However, what if you’re ahead of schedule, but costs are higher than your planned budget? Or, what if you’re behind schedule, but costs are lower than you first calculated?
Project management software can help you with variance analysis. ProjectManager has real-time dashboards that collect live data and automatically calculate variance analyses for you. The results are then displayed on colorful charts representing cost variance, schedule variance and more. Plus, there’s no setup required! Monitoring the six project metrics shown on the real-time dashboard is how you keep track of your project as it unfolds. Get started with ProjectManager for free today.
Knowing the earned value helps provide deeper information on your project. And when learning about earned value, it’s important to remember that there are three terms associated with it, each of which is slightly different.
- Earned Value Analysis (EVA): This project management technique is quantitative. It evaluates project performance by figuring out the likely results of the project. It does this by comparing the progress and budget of work planned to the actual costs.
- Earned Value Management (EVM): This methodology measures project performance with an integrated schedule and budget, which is based on the project work breakdown structure (WBS).
- Earned Value Management System (EVMS): This is the collection of tools, templates, processes and procedures that an organization uses to do EVM.
Earned Value Management Core Concepts
Earned value analysis based on a performance measurement baseline is how you can compare your project plan to your project execution. This allows project managers to answer three questions: Where were we, where are we now and where are we going? This requires accessing the following data points.
Planned Value (PV)
The planned value is where your project tasks should be at a specific point in the project schedule and cost estimation. These two values are the planned value of where you expect to be within the current reporting period. This value can either be cumulative or current. The former is the approved budget for planned activities that have to be done generally throughout the whole project. The latter is the approved budget for those planned activities being done over a specific period of the project, whether days, weeks or months.
Planned Value (PV) = % of project completed (planned) * Project Budget
Actual Cost (AC)
This is the actual cost of the work that’s been completed over a specific project period. The value refers to what has been spent, either cumulatively or currently. That is, either the actual cost for work done up to the point in which it is being calculated or over a given period of days, weeks or months.
Actual Cost (AC) = Actual costs to date
Earned Value (EV)
This is the quantification of the value of the work that’s been performed up to a certain date in the project. The cumulative earned value is the sum of the budget over the whole project up to the date of the calculation while the current earned value is only carried out for a given period.
Earned Value = % of completed work * BAC (Budget at Completion)
How Do You Calculate Earned Value Management?
Now that we’ve learned about the foundational concepts of EVM, let’s learn how to calculate earned value management. To do so, we’ll use simple earned value management formulas, which are explained below.
Earned Value Management Formulas
There are calculations that can be done quickly and easily to execute EVM. EVM formulas can be divided into two groups: performance indexes and variance analysis formulas. Here they are:
Schedule Variance (SV)
The schedule variance is a way for project managers to figure out how much ahead or behind schedule, they are in the project. The formula to figure this out is as follows.
Schedule Variance (SV) = Earned value (EV) – Planned Value (PV)
Cost Variance (CV)
Cost variance is the difference between the actual cost of the project at that point it’s calculated compared against the planned budget cost for that period of time in the project plan. The formula is below.
Cost Variance (CV) = Earned value (EV) – Actual Cost (AC)
Schedule Performance Index (SPI)
The schedule performance index is a subset of EVM, which shows whether a project is ahead or behind schedule. It calculates the ratio of the performed work to the scheduled work. The formula for this is as follows.
Schedule Performance Index (SPI) = Earned value (EV) / Planned Value (PV)
Calculating the schedule performance index involves dividing the EV by the PV to measure progress achieved against where you expected to progress at a certain point. If you’ve come up with a value less than 1.0, it means that you’ve done less work than you projected for this point. While a value greater than 1.0 means you’ve completed more than was planned.
Cost Performance Index (CPI)
The cost performance index measures how efficient costs are in the project. It’s shown in a ratio of earned value to actual costs.
Cost Performance Index (CPI) = Earned Value (EV) / Actual Cost (AC)
For this calculation, you divide EV by the AC to measure the value of work completed against its actual cost. Again, if you reach a figure less than 1.0, your costs are higher than budgeted. A number higher than 1.0 means the costs are less than budgeted.
Estimated At Completion (EAC)
Estimated at completion is the current expectation of what the total costs will be for the project when it is done.
Estimated at Completion (EAC) = Budget at completion (BAC) / Cost performance index (CPI)
With this calculation, you divide the total project budget by the CPI value you figured out above.
EVM Is Great, With a Few Caveats
EVM is a technique that you can use to manage and control your project, but EVM won’t solve everything. It doesn’t always work on your project and it’s not a magic bullet that can pierce all project problems. In fact, it has some pitfalls.
You can’t rely solely on earned value management. Remember, it’s merely calculating a single objective data point. The earned value of your project can change and can change fast. Naturally, cost and progress are seldom reflected in the actual project as they are when you’re executing the project. So, EVM acts as a safeguard and provides useful data. It’s best to make these calculations monthly or more frequently if your project is shorter in duration.
EVM Doesn’t Ensure Quality
There are some things that EVM doesn’t offer a window to view, such as customer satisfaction and the quality of the project. The project performance as it relates to important factors such as schedule and budget are tracked with EVM. But a successful project is not one merely brought in on time and within budget. If your customer is unhappy or the project or service quality is poor, there’s a big problem regardless of meeting schedule and budget demands.
Without Accurate Data, EVM is Useless
If you don’t include all actual costs in your calculations, your results won’t accurately reflect the progress or performance of the project. If you’re using software that automatically makes these calculations you need to be doubly cautious, as it might overlook critical data and give you a misleading result.
EVM Needs Context
Finally, don’t just deliver the numbers to customers, stakeholders or whomever you’re reporting to—they need to know what those numbers mean and how you’re using them. Be clear in your language and avoid jargon. You know what you’re talking about, but it’s important that who you’re talking to understands as well. Don’t dumb it down, of course; just speak clearly and simply. Being able to effectively communicate EVM is as important as being able to calculate it.
Measure Performance With ProjectManager
Calculating performance is crucial to keeping projects on schedule and within budget, but what if you don’t have a calculator?
