How to Measure Resource Utilization for a Project

ProjectManager

Every project team needs resources to complete tasks. They need tools, equipment, materials and more to get the job done. Managing resources throughout the project life cycle is critical for success, and measuring resource utilization is the first step in doing so.

Those who are tasked with managing a project and delivering it successfully must know how to keep their teams productive and make the most out of resource utilization. One of the most important aspects of this is proper planning and ensuring there’s enough time and capacity for project teams to do what’s asked of them.

In other words, project managers must hone the crucial skill of resource management. Your resources are more than just the team, and every resource plays a role in moving the project forward without obstruction. When you’re specifically talking about your team’s time, though, then you’re dealing with resource utilization.

What Is Resource Utilization?

In project management, resource utilization is a measurement of how many billable hours are assigned to a worker. Therefore, knowing your resource utilization is very important to understand your costs, and make decisions such as adjusting your project plan, budget or schedule.

Resource utilization is how project managers find out how much capacity their team has over a period of time, and ascertain which of their resources are under or over-utilized. It gives managers a window into how many hours their team is spending on the project. Resource utilization differs from resource allocation, and that difference is important to understand.

Resource utilization can be overwhelming without the right resource management tools. To measure resource utilization, project managers use software equipped with time tracking, task management and resource planning features such as timesheets and Gantt charts. ProjectManager has the ideal tools to measure, track and manage resource utilization. Get started for free.

Resource Utilization vs. Resource Allocation

Resource allocation is how a project manager picks his or her team and assigns resources for tasks throughout the project life cycle. This includes any reassignments and changes to their team’s workload as needs arise.

However, resource utilization is more strategic in that it measures how effective your resources are. Ideally, you’ll organize your project with resource allocation and drive its success by measuring resource utilization and optimizing how you’re using your team’s time. Both processes work hand in hand, so it’s critical that you have a robust resource planning tool that can help you measure effectiveness.

Types of Resource Utilization

Even though there’s only one definition of resource utilization, there are different approaches to measure it that are used for different purposes in resource planning. Here are the most commonly used types of resource utilization.

Overall Utilization

When measuring overall resource utilization, project managers add the time a team member spends on all billable, non-billable and strategic activities that he or she is assigned and compares it against his/her total time available. This helps determine whether the team member’s time is being used entirely and how it could be better utilized.

Billable Utilization

Billable hours are labor hours that are charged to a client once the work is completed. Therefore, billable resource utilization is calculated when a client or project manager needs to determine the number of billable hours of a worker, excluding non-billable hours and strategic activities. This resource utilization method is very useful when gauging and comparing employee performance.

Non-Billable Utilization

All of the activities that aren’t considered billable are categorized as non-billable. This method is used when project managers need to assess how efficient their resource utilization is. A high non-billable utilization might be a sign that the team is spending too much time on non-critical tasks.

Strategic Utilization

Organizations have long-term goals which are part of their strategic plans. To achieve those plans, they need to execute strategic projects and programs. Strategic resource utilization measures the number of hours team members are spending on those strategic activities.

Now that we’ve learned about the different types of resource utilization, we can use resource utilization formulas to measure it.

Resource Utilization Formula

There are many formulas that calculate resource utilization. They’re used to get different insights and you can even create one to meet your resource management needs. The most commonly used resource utilization formula is the full-time equivalent formula (FTE):

Resource utilization = Worker’s Allocated Hours / Worker’s Total Available Hours * 100

This formula calculates the resource utilization percentage of each team member or the team as a whole based on the relation between their total available time and the hours they’ve worked. To measure the different types of resource utilization, simply change the worker’s allocated hours value to billable, non-billable and strategic hours.

How to Measure Resource Utilization

Today, most companies use project management software equipped with time tracking and resource management features to measure, track and manage their resource utilization at any point in time. Here are some general steps you can follow to measure resource utilization with the help of software such as ProjectManager.

1. Define Billable and Non-Billable Hours

The first step to measuring resource utilization accurately is to define the billable and non-billable activities that your team will execute. Once you define that you can calculate overall utilization, billable utilization and non-billable utilization.

2. Determine the Available Hours of Each Team Member

Now you’ll need to determine the available hours for each team member based on their contracts, which can be either full-time, part-time or unit pricing, among others. Now you have the information you need to assign work and use timesheets to keep track of resource utilization.

3. Use Timesheets to Measure Resource Utilization

Timesheets are an essential tool to measure resource utilization because they let you document your team’s time, use resource utilization formulas and measure your overall resource utilization.

4. Use the Resource Utilization Formula

Based on your needs, you can choose to measure billable, non-billable or strategic resource utilization. Simply use the resource utilization formulas above to measure your resource utilization.

5. Determine Employee’s Productivity

Based on your resource utilization analysis, you can determine which workers are overallocated, under-allocated and which of them have a low performance based on a peer comparative analysis and the work they’ve done in terms of deliverables.

Why Is Resource Utilization Important?

It should be clear why resource utilization is critical to running a project, but it doesn’t hurt to dive deeper into the benefits of such a process. For one, utilizing your resources is key to staying productive in your project. If your team is overburdened, they’re not going to perform at their optimum level.

Resource utilization also provides visibility into your project. The more transparency and the better you monitor your project, the less likely it is that you’ll miss important steps. This allows you to catch risks before they develop into problems that could sidetrack you.

All of this means that you’re going to get more bang for your buck—or in business terms, ROI. If you’re making sure your resources are not overtaxed or overused, then you’re going to work more efficiently and add money to your bottom line.

Finally, the process of resource utilization gives project managers the tools to work more agilely. They have the flexibility to reschedule their resources fast, which means they can avoid problems or untangle themselves from issues quickly. It keeps the project on track.
