Resource utilization: How to maximize efficiency and productivity

A foundational aspect of a project manager’s job is finding the right people for a task. Without tightly managed human resources, team members will struggle to deliver their work on time. They may even become so exhausted that they burn out.

That’s why every project manager should carefully track resource utilization. By monitoring resource utilization in project management, teams can control the billable hours dedicated to each task, optimize staff deployment, and boost overall productivity. This ultimately improves the company’s bottom line while safeguarding employees’ well-being.

Let’s explore resource utilization and uncover its importance for your team and project outcomes.

What is resource utilization?

Resource utilization is a project management metric tracking the percentage of total resources currently dedicated to a specific project. Resources may include people or capital assets (e.g., equipment).

Tracking resource utilization helps project managers visualize their team’s performance and productivity levels over time. It also allows them to evenly distribute workloads and get the most out of available assets. Should the data indicate team members are over or underutilized, project managers can step in to adjust workloads accordingly. This strategy eliminates burnout, boosts group morale, and mitigates production bottlenecks. 

Resource allocation vs. resource utilization

Allocation and utilization are vital but distinct facets of resource planning. Resource utilization measures the efficiency and availability of deployed resources. Resource allocation is a project management process that involves determining required resources and strategically deploying them to tasks throughout a project’s lifecycle.

As part of the larger resource management process, resource allocation also covers reassignment and workload adjustment in response to changing circumstances.

Using the resource utilization formula

Project managers calculate resource utilization rates using project data – typically billable hours. Here is the most common formula:

Resource utilization = (Total billable hours / Total available working hours) X 100

The formula determines individual or overall team efficiency by comparing the total number of hours worked on a project against the number of available hours and multiplying it by 100 to give a utilization percentage.

For example, resource utilization for a team member working seven hours a day, five days a week on a single project looks like this:

Resource utilization = (Total billable hours / Total available working hours) X 100

Resource utilization = (35 hours / 40 hours) X 100

Resource utilization = 87.5%

According to the formula, that team member’s resource utilization is 87.5% of the available capacity for that project.

Project managers typically aim for an 80% resource utilization rate. This level delivers effective team deployment while reserving additional schedule buffering to address emergencies or administrative tasks without overloading team members. Additional factors (e.g., vacation days, overtime, and reporting time vs. actual time) impact the rate, so project managers must adjust accordingly.

Benefits of tracking resource utilization

Project managers who measure resource utilization rates can get the most from their teams. Here are some advantages of incorporating this metric into resource allocation decisions:

Increases morale

A corporate culture that safeguards employees’ work-life balance through effective resource management creates a positive working environment. By capping billable hours, companies produce higher retention rates and improved performance. Absenteeism and recruiting costs decrease, improving the bottom line.

Boosts profits

A company that implements a system to track billable hours and encourages team members to use it generates data to inform resource allocation forecasts for future project plans. Resource utilization statistics also improve cost estimates used in client quotes, ensuring fair payment for completed projects.

In addition, project managers can quickly determine resource availability and avoid a last-minute scramble to find capacity for vital tasks. Without vital resource utilization metrics, they may overcommit and be forced to pay for overtime or additional hiring, cutting into profits.

Manages scope creep

Goals and outcomes that expand beyond the original project plan can derail an entire initiative. By documenting resource utilization, project managers are better equipped to determine whether employees can accommodate new requests. If they need to limit or turn down additional work, they can provide concrete, data-backed reasons to stakeholders. 

Tips to improve resource utilization

Tracking and managing resource utilization benefits both the company and its employees. Here are a few ways project management can maximize productivity:

Leverage resource management software

Calculating resource utilization with a spreadsheet is labor-intensive and error-prone. Project managers waste valuable time manually inputting hours and programming formulas to determine individual utilization rates.

Instead, use resource management software like Tempo’s Capacity Planner and Timesheets to streamline task tracking and management. These tools automatically record and process vital data so project managers can calculate resource utilization and forecast productivity.

Establish a resource planning schedule

A resource planning schedule provides a comprehensive view of a team’s time usage and resource levels, allowing the project manager to determine how to deploy each team member effectively. The process improves resource utilization, giving team members clear timelines and due dates to organize their workloads and deliver outcomes on schedule. 

Track time

Billable hours tracking is crucial to effective resource utilization. It helps project management determine whether anyone is over or underutilized and identifies opportunities to boost productivity.

Managers can more easily spot issues when employees log billable hours separately for each project task. They’ll know when to rebalance workloads or offer additional training. 

Draft resource estimates

When drafting a proposal for a client, leaders need to know whether the company has adequate resources to complete the work. Access to resource utilization rates helps project managers forecast and plan staffing requirements, minimizing the need to rework schedules and reassign work. They can produce more accurate timelines for each phase of the project lifecycle, managing client expectations and avoiding scope creep. 

Decrease nonbillable activities

Meetings, research, and correspondence are essential activities, but they don’t contribute to billable hours. Resource utilization metrics illustrate how time is spent so project management can maximize billable hours and direct team members toward work that drives revenue. 

Analyze actual vs. planned hours

Projects rarely follow plans to the letter. Compare how the team actually spends its time against planned or booked hours to locate areas for improvement.

If a project manager allocates 100 hours to complete work, but the team only takes 60, they know to adjust the next project plan to better utilize resources. Postmortem reviews can uncover the source of any discrepancies, helping project managers improve team workloads and generate more precise quotes for clients.

Optimizing resource utilization with Tempo

Instead of using spreadsheets to calculate resource allocation, take your project management tools to the next level with Tempo’s Capacity Planner. Capacity Planner integrates with Jira to optimize resource utilization by automatically scheduling tasks and rebalancing workloads according to employees’ availability and skill set.

Capacity Planner combines with Timesheets, our time-tracking tool, to visualize plans and shared resources. Together, these solutions enable informed decisions that optimize resource utilization across multiple projects.
