As a temporary conclusion to our Earned Value Management blog series, we’d like to provide you with an EVM formula cheat sheet. This file contains all essential formulas for calculating the Earned Value metrics, indicators and measures. Download the .pdf for free.Read more
When using the Critical Path Method (CPM) in traditional project management software, Total Float (TF) and Free Float (FF) are calculated, which most project managers know and use. But there is more to it. We can gain deeper insight in which timeframe an activity can shift, and the effects on the related activities by calling in two more types of float. The Interfering Float (INTF) and the Independent Float (INDF). Let me tell you how to interpret them, help decision making, and support claim prevention/preparation by using these four characteristics.Read more
You are halfway through your project and you want to know if you are still going to achieve your project objectives. By using an Earned Value Management System, you know how to estimate your total expected costs (Estimate at Completion), but what about your deadline? Based on your current information, can you say something about the expected finish date of your project? This blog gives you an overview of how to use Earned Schedule to predict your project finish date.
Do you feel your budgeting process has failed from the start of your project? Have you learned that you overbudgeted or underbudgeted the activities in your performance measurement baseline (PMB)? Are you willing to take your Earned Value Analysis (EVA) to the next level? Then this is a blog post for you.Read more
I’m a true advocate for using (a basic implementation) of EVM on all your projects, or at least the philosophy. The use of Earned Value Management metrics gives a good insight in your current project status at a simple glance. By planning your project carefully and assigning budgets, in hours, euros, documents, resources, to your activities, a world of possibilities opens. Every project stakeholder can have their own personalized reports on their points of interest, with their own style of preference.
The level of project controls maturity has a great impact on the insight you can gain using the same, simple metrics provided by EVM. Let me take you through the different levels of reporting maturities, followed by some ideas on how to improve further than the classic methods.Read more
How can we get the most out of our EVM metrics? We’ve evaluated our current cost and schedule performance, and have seen how to forecast the Estimate At Completion (EAC). Now is the time to evaluate the realism of our project’s Budget At Completion (BAC). Following the current conditions, is the aimed for budget still sufficient?
One of the most powerful (and underutilized) measures EVM grants us is the To Complete Performance Index. This is the Cost Performance Index (CPI) at which you must execute the remainder of the work to deliver the project within a certain budget. The budget aimed for has sometimes become idealistic. Comparing the TCPI with the current CPI gives a good insight on whether the foreseen budget or the EAC remain realistic. The difference between the cumulative CPI and the TCPI value should trigger the re-evaluation of the Estimate At Completion.Read more
Now we’ve learned the basics of Earned Value Management calculations (see this blog), it’s time to introduce a new metric to define our project’s health. As you’ve noticed all previous metrics and parameters were either percental (CPI, SPI, TCPI) or monetary/unitary (CV, SV). But what does a schedule variance of € 10.000 tell us? First, a delay expressed in monetary units is somewhat strange. Second, we will show later in this blog post that this metric is subject to a major fallacy. It is to be replaced with a more comprehensive one. Time for a change.Read more
