High utilization can protect margins – until it starts damaging delivery and retention. Learn how to spot overutilization and build healthier capacity plans.
High utilization can look like a win. People are busy, billable hours are up, and productivity is high. That means you’re on the right track, right?
Not necessarily. When people are consistently planned to their full capacity (or beyond), the cost shows up somewhere else – usually in rushed work, burned-out people, and high turnover.
While the occasional challenging project provides an opportunity for mutual achievement, routinely overutilizing your people has hidden costs.
In this article, we explore how employee overutilization occurs, the dangers it presents to your team, and how to prevent it.
A person’s utilization rate is a crucial metric for project managers to monitor, to ensure effective resource management.
Overutilization is when someone’s assigned workload exceeds their real capacity, based on the hours they are contracted to work. That doesn’t always mean they’re scheduled at 100% capacity or more. A person can be overworked at 85% billable utilization if their remaining time is filled with other productive work – think meetings, admin, training.
A consistently high utilization rate is an indicator of a too-heavy workload where people may face difficulties in attaining a healthy work-life balance. Overutilized people are more susceptible to burnout, and the company can suffer when a feeling of fatigue creeps into work processes, reducing productivity and compromising work quality.
While companies want to get the most out of their teams, few set out intending to overload people. So how does overutilization creep in?
Overutilization often starts with a target that looks reasonable in a spreadsheet but ignores how work actually happens. If a utilization target does not account for PTO, holidays, training, admin, mentoring, internal work, and business development, people are effectively expected to make that time appear from nowhere.
As David Binnings, Senior Director of Go-to-Market Services Strategy & Operations at Docusign, put it In Runn’s webinar, The Utilization Dilemma:
When you're setting those targets, it's important that you think through all these factors... Having that visibility, showing what those are, is vital. So I think it's important that you call those things out explicitly – it shows the teams, 'hey, we've thought through this.' This is how much time we've allowed for these things."
➡️ Utilization Isn't the Enemy – But the Way You Frame It Might Be
In software delivery firms, overutilization often comes from visibility gaps. Sales sees upcoming demand. Delivery sees project pressure. Finance sees revenue targets.
If those views are not connected, the plan can look viable while the team doing the work is already over capacity. A new client engagement may be sold before anyone confirms whether the right people are available.
This is a common challenge. In Runn’s 2026 State of Resource Management report, 47% of respondents named “lack of visibility into capacity and demand” as a top resource management challenge, while 42% pointed to “misalignment between capacity and demand.”
This can lead to understaffing, whether in relation to a specific person whose skills are in high demand, or a team that is under-resourced on all sides. These issues tend to lead to long-term overutilization of overstretched employees.
Some overutilization is not spread evenly across the team. It clusters around people with scarce skills: the cloud architect, the senior QA lead, the integration specialist, the project manager who knows the client history. When planning happens by role rather than skill, these people become the default answer to every urgent request.
The same thing happens when project plans underestimate effort. If a project needs deep AWS experience, assigning “a developer” is not enough. The plan needs to reflect the actual capability required.
Scope changes, urgent client requests, and new sales commitments can quickly lead to overload. Change is inevitable in project-based work – what matters is how you adapt to it, re-forecasting the work, timelines, and people plans.
Overutilization can be problematic for the organization's profitability, project performance, and employee wellbeing.
Chronic overutilization creates the conditions for burnout, which the World Health Organization defines as “a syndrome conceptualized as resulting from chronic workplace stress that has not been successfully managed.”
If a person is in a constant state of overwork, they may suffer from mental and physical exhaustion. Burnout can lead to disengagement, sick leave, lower performance, and strained working relationships. That matters for the person experiencing it, and it matters for the business relying on their judgment, creativity, and client relationships.
When people are overloaded, they try to claw back time wherever possible. This often means cutting corners, even when they care deeply about the work.
Code reviews get rushed. Documentation slips. QA cycles compress. Small mistakes are more likely to reach the client.
The team may still be working hard, but more effort goes into correction than progress, which will only compound the issue.
A delivery team can be highly utilized and still deliver a poor client experience. If work is rushed, handovers are weak, or the right expertise is unavailable at the right time, clients feel the difference.
The impact can show up in many ways, from missed deadlines to lower trust. For project-based businesses, that goes beyond being a delivery issue – potentially risking reputation.
Attrition is where overutilization becomes visibly expensive. When overworked people leave in search of more sustainable work environments, the business loses delivery knowledge, client context, and future delivery capacity.
Overutilization can become a vicious cycle – it drives high employee turnover, which in turn leads to understaffing, causing a heavier workload for the people who remain.
When you make a decision to increase utilization, there will be a threshold at which that becomes unattainable, and folks get discouraged and burned out, and then they leave. Attrition is an expensive thing. You can pull this lever if you want – but the cost will come differently, not unexpectedly, and very painfully." – Beth Hunter, Resource Experience Management Leader, Rehmann
High turnover rates create additional challenges in replacing talent, especially in the current business environment with increased competition for highly skilled people.
A team booked to the limit has little room to improve. Training, experimentation, process improvement, and mentoring become “nice to have” activities, even though they are what keep future delivery strong.
Preventing overutilization is about building plans that people can actually deliver.
Managers must find the right balance for optimal resource utilization: enough work to keep people productive, profitable, and engaged, but not so much that the team loses quality, trust, or resilience. Underutilization creates its own problems, but overutilization is often harder to spot because it can look like success at first.
To achieve optimal, balanced resource utilization, we recommend paying attention to six key areas:
Utilization tells you how people’s time is being used. It does not tell you whether that time is creating the right outcomes.
"It's not just 'go be busy,'” David Binnings says. “It's be busy with intent. What are we trying to do? Be productive – try to hit the goals of what your organization is trying to achieve.”
Track utilization alongside measures such as project margin, delivery milestones, customer satisfaction, time to value, throughput, rework, and team sentiment.
For teams running fixed-price engagements, throughput deserves particular attention. How quickly work moves through the team directly affects when you can onboard the next project – and whether the margin you quoted at the start is the margin you land with at the end.

Setting fair targets starts with understanding real capacity.
Build from the working year, then account for PTO, holidays, training, admin, mentoring, internal work, and the kind of client delivery each role performs.
Remember, a senior engineer and a delivery lead may need different targets because they contribute value in different ways.
One widely recommended approach is to anchor your targets to a consistent denominator – one that every department, from finance to HR to delivery, can work from. David Binnings recommends using 2080: the total available working hours in a year for a full-time person working 40 hours per week across 52 weeks.
PTO, holidays, training, and admin are then carved out explicitly and visibly from that baseline, rather than quietly removed from the denominator.
This matters because when different teams are calculating utilization differently, conversations about capacity, hiring, and margin quickly become misaligned. A shared denominator keeps everyone honest – and keeps the plan grounded in reality.
For global teams, adjust the baseline by region. A 37.5-hour work week, local holidays, and country-specific leave policies should be reflected clearly rather than buried in the target.
Runn co-founder Tim Copeland shared this example from a conversation with a CFO at a large professional services firm:
For about 20 years, utilization was their North Star. But they realized the skills their workforce had weren't the most sought-after in the market – so they stepped back, redirected toward training and development, and deliberately lowered their targets. Utilization went down. Profitability went up. And the workforce experienced less stress. By targeting 80% instead of 100%, they left room for creativity and development. It made the environment more productive, not less."
Adequate staffing is not only a headcount question – you also need to consider skills.
You may have ten backend developers available, but that doesn’t matter if the project needs an integration specialist, cloud architect, QA lead, and a technical project manager.
For custom software and IT solutions firms, this is where skills-based planning comes in. You need to know who is available, what they can do, and whether assigning them protects both delivery quality and future capacity.
Rather than overallocating people because they are technically available, you can ensure the right person is assigned to the right tasks at the right time.

Uneven workload is one of the easiest overutilization risks to overlook.
Sometimes, unequal workloads may mean one person is overloaded across several projects while the team’s average still looks healthy. This is especially common when one person becomes the safest choice for urgent work, which makes them harder to protect.
As well as placing that individual on the path to burnout, uneven workload distribution sparks resentment within your people, which disrupts effective teamwork.
To ensure fairly distributed workloads, review workload at the individual, role, skill, team, and portfolio level so hidden pressure does not disappear inside an average.
Through forecasting, a company can make educated predictions about the resources that will be needed to handle upcoming projects. This allows management to make preparations for adequate staffing.
Capacity planning – which involves assessing the current and upcoming workload of each team member, and assigning them tasks that fit their capacity – should connect current assignments, tentative work, sales pipeline, hiring plans, and known time off.
When a new project moves from likely to committed, the plan should show what changes: who becomes overbooked, which skills become constrained, whether margin changes, and whether hiring or contractors are needed.

As delivery teams grow, the risks of planning via spreadsheets multiply: outdated data, conflicting versions, hidden overbookings, and decisions based on assumptions rather than live capacity.
A resource management platform like Runn helps you see utilization, availability, capacity, skills, and project demand in one place. You can spot overbooked people, model tentative projects, search for people by skill, and test what happens if timelines shift before those changes turn into delivery problems.
For a practical walkthrough, watch how utilization reports can help you spot both overload and idle capacity:
Overutilization is easy to rationalize when deadlines are tight and demand is high. But the longer your people are working over capacity, the higher the risk becomes. People burn out. Quality drops. Clients feel the strain. Senior specialists become bottlenecks. Good people leave. Hiring plans turn reactive.
The answer is not to stop measuring utilization. It is to measure it properly, interpret it carefully, and balance it with the metrics that show whether work is actually healthy: client satisfaction, delivery quality, margin, team capacity, skill development, and retention.
With the right visibility, leaders can spot overutilization before it becomes a crisis. They can rebalance work, protect critical skills, plan hiring earlier, and build delivery teams that are productive without being permanently stretched.
