What is Resource Levelling?

Resource levelling is a project management strategy used to address overallocation and timing conflicts, ensuring that project tasks can be completed using the resources at hand. These resources may include personnel time, equipment, materials, or any tools required to carry out the work. The goal is to adjust the schedule or redistribute workloads so that no resource is stretched too thin, keeping the project both realistic and efficient.

Why Use Resource Levelling?

The main aim of resource levelling is to make the best use of the resources already available, all while staying within the project’s constraints for time, budget, and scope. This technique can be especially tough for project managers, as it often involves juggling resource needs across several tasks—or even multiple projects—without causing bottlenecks.

Depending on your team’s priorities, resource levelling can lead to different outcomes:

If sticking to the original timeline is essential, additional resources might need to be brought in.

If you’re limited to existing resources, the project timeline may need to be pushed back.

By fine-tuning how resources are allocated or tweaking the schedule, resource leveling helps prevent burnout, reduce delays, and keep the overall quality of the deliverables intact.

When Should You Use Resource Levelling?

Resource levelling is a valuable method for ensuring that your team isn’t stretched too thin while still giving each project the attention and support it needs to succeed. It plays a key role not only in project execution but also in promoting a healthier work-life balance for your team. Below are several reasons why implementing resource levelling can benefit your projects:

To Make the Most of Existing Resources
This technique helps you evaluate how to use your current assets—such as time, people, and tools—more effectively. It allows you to prioritize which tasks may need more support and which can be adjusted based on timeline flexibility.

To Reduce Resource Shortages
By levelling resources, you can avoid major delays and keep labor and budget overruns under control. It helps align project demand with your organization’s actual capacity without pushing financial or operational limits.

To Avoid Overburdening the Team
When resources are assigned to too many tasks at once, it often leads to burnout. Resource levelling addresses these issues early by distributing workloads more evenly and shifting schedules when necessary to prevent overload.

To Maintain Deliverable Quality
Balancing timelines and resource use ensures that output quality doesn’t suffer. Resource levelling helps you meet client and stakeholder expectations by maintaining consistency in project standards while avoiding rushed or incomplete work.
In summary, resource levelling is an effective tool for managing tight budgets, avoiding overuse of resources, and minimizing delays—all while supporting the well-being and productivity of your team.

Resource Levelling in Action: Practical Examples

Understanding how resource levelling works can help you better manage your team’s workload and avoid burnout or missed deadlines. Here are a few real-world examples that illustrate how different teams might use resource levelling to stay on track:

Example 1: Shifting the Start Date to Free Up Key Talent

A product development project is about to begin, but the lead designer who needs to create the first round of wireframes is already committed to another task. Since no one else on the team has the necessary skills, the manager postpones the start by two days. This minor shift allows the designer to complete their current task and immediately begin work on the new project—without affecting the final deadline.

Example 2: Scaling Up with New Tools or Support

The tech support department is flooded with help desk tickets due to a widespread malware issue affecting employee devices. The current antivirus software isn’t sufficient to manage the problem efficiently. To reduce downtime, the team upgrades to more advanced software and brings in additional temporary IT staff. These new resources allow the team to handle the crisis without pushing back other planned work.

Example 3: Extending the Timeline to Accommodate Availability

A digital marketing team is preparing to roll out a new ad campaign, but the team lead responsible for approvals is on unexpected medical leave. Rather than rush the launch or shift responsibilities, the team opts to delay the release by a few days. Since the campaign isn’t tied to a specific date, the delay ensures the project maintains its quality and alignment with company goals.

Using Resource Levelling to Your Advantage

No matter what type of team you lead—marketing, IT, sales, or product—resource levelling can help you avoid overload, maintain momentum, and deliver better results. Once you choose a strategy to resolve your resource clash, make sure to loop in your team and clearly outline next steps. A meeting agenda template can help you stay organized and communicate changes effectively.

Levelling Up Your Project Management Skills

Incorporating resource levelling into your project planning toolbox will help you stay flexible and resilient under pressure. Some smart approaches include:

Adjusting start or end dates to fit team member schedules

Investing in new tools or extra hands to ease workload pressure

Reassigning tasks based on skills, availability, and bandwidth

When applied thoughtfully, these strategies can help you keep projects on schedule—even when your team is stretched thin.

Understanding the Critical Path Method (CPM)

The Critical Path Method is a widely used project scheduling technique that helps managers identify the most essential tasks for completing a project on time. Unlike some other resource levelling methods, CPM does not initially consider resource availability—it focuses purely on time and task dependency.

This method involves mapping out all activities in a project and linking them based on task dependencies. The goal is to determine the longest chain of dependent tasks, which becomes the critical path—the sequence of work that directly determines the project’s overall duration.

How CPM Works

Once all tasks are laid out and connected, you calculate two key values for each task:

Earliest Start/Finish: The soonest a task can begin and end.

Latest Start/Finish: The latest a task can begin and still not delay the overall project.

This helps reveal float, or how much flexibility each task has.

Types of Floats:

Total Float:
The maximum time a task can be delayed without affecting the project’s end date.
Formula:
Total Float = Late Finish – Early Finish
or
Late Start – Early Start

Free Float:
How long a task can be delayed without affecting the start time of the next dependent task.
Formula:
Free Float = Early Start of Next Task – Early Finish of Current Task

Tasks that fall on the critical path have zero float. Any delay in these tasks will directly push back the project deadline.

Example: Applying CPM in IT

Let’s imagine an IT department is upgrading the company’s security infrastructure. The team outlines four key activities:

Task A (Critical): Install the new firewall

Task B (Critical): Configure system settings

Task C (Non-critical): Create backup documentation

Task D (Non-critical): Train internal staff

Tasks A and B are essential and form the critical path. Any delay in either will delay the entire project. However, Tasks C and D have some buffer time—they can be moved slightly without impacting the go-live date of the new system.

Why CPM Matters

Knowing the critical path allows project managers to focus their attention where it matters most. By identifying tasks with no wiggle room, teams can better prioritize resources, reduce risks, and prevent last-minute surprises.

In short, CPM gives you a clearer view of what must happen on time and what can afford a delay—making it a powerful planning and decision-making tool in any project.

Critical Path Method (CPM)

The Critical Path Method is a widely adopted scheduling strategy that helps you figure out the minimum duration needed to finish a project—without factoring in resource limitations. It involves laying out all dependent tasks in a logical sequence to identify the longest string of activities that must be completed to reach the finish line.

This sequence is called the critical path, and any delay in these tasks directly affects the overall project timeline.

Once you identify which tasks lie on this critical path, you can assess their scheduling flexibility, commonly referred to as float:

Total Float: The maximum delay allowed for a task without affecting the final project deadline
Formula: Late Finish – Early Finish (or Late Start – Early Start)

Free Float: The amount of time a task can be delayed without delaying the next dependent activity
Formula: Early Start of Next Task – Early Finish of Current Task

If a task has zero float, it means it’s on the critical path. A delay in this task will push back the project.

CPM Example:

Let’s consider a company-wide IT upgrade. Here’s how tasks could be broken down:

Critical Tasks:

Remove existing security software across all systems within 2 days

Deploy and validate the new software across all devices in 4 days

Non-Critical Tasks:

Confirm procurement details with the vendor (1 day)

Draft an internal usage guide for the new software (2 days)

The total time required to complete the critical tasks is 6 days—this becomes the shortest possible project duration. The non-critical tasks have some buffer and don’t affect the main deadline unless delayed extensively.

Fast Tracking

In projects where deadlines are tight and time is of the essence; fast tracking can be used to complete the work more quickly. This approach involves overlapping tasks that are typically done in sequence—provided they don’t depend heavily on each other.

For instance, your team may begin backend development on a website while the frontend design is still being finalized. Though it helps meet tight deadlines, fast tracking also increases the risk of rework if upstream tasks change or aren’t completed as expected.

Crashing

When timesaving is critical and fast tracking isn’t feasible, crashing comes into play. This technique shortens project timelines by adding extra resources to high-impact tasks—like hiring more people or purchasing faster tools.

Let’s say the content marketing team suddenly faces a tighter deadline. They need two more writers but have no internal availability. Rather than reassign internal staff, the manager brings in trusted freelance writers who can jump in immediately, minimizing the risk and keeping the project moving.

Always make sure you have client or executive sign-off before allocating additional budget or resources.

Critical Chain Method (CCM)

The Critical Chain Method is a more modern spin on the Critical Path Method. Unlike CPM, CCM considers resource availability and limitations from the beginning.

In this method, you plan around both task dependencies and who’s available to work on them—ensuring that no individual is scheduled for two tasks at the same time. Once the chain of resource-bound activities is outlined, a project buffer is added at the end of the schedule to absorb any unexpected delays.

For example, if a team is preparing to launch a digital asset, they determine who’s needed: a writer, an editor, a designer, and a developer. A buffer of 5 days is placed after the final task to act as a cushion against any handoff delays between departments.

By including this buffer, teams can better manage interruptions without affecting the final delivery.

Resource Levelling Tools and Techniques

As you get more hands-on with resource levelling, several tools can make your work easier and more efficient:

Gantt Charts

Visual project timelines that show task durations, dependencies, and start/end dates. Gantt charts are great for spotting schedule clashes early and adjusting plans on the go.

Project Management Platforms

Many modern tools (like Microsoft Project or Asana) offer built-in resource levelling features. These can automatically adjust schedules to avoid double-booking team members and help allocate resources more efficiently.

Network Diagrams

These flow-style charts show the order and connection between tasks. Each task is represented as a node, with arrows indicating dependencies. They help you visually identify the critical path and see which tasks can shift without delaying the project.

Learn from Past Projects

Reviewing previous project schedules—both successful and problematic—can help you avoid repeated mistakes. You’ll gain insights into realistic timelines, typical bottlenecks, and which resources were overused.

Estimate Resource Needs Realistically

A well-estimated plan makes resource levelling smoother. Here are a few practical tips:

Include your team in estimation to eliminate blind spots

Build in risks or uncertainties

Estimate using ranges rather than fixed numbers

Stick with one estimation method for consistency

Resource Levelling vs. Resource Smoothing

Resource Levelling vs. Resource Smoothing: Key Differences Explained

Managing resources effectively is a crucial part of any successful project. Two commonly used techniques to manage resources are resource levelling and resource smoothing. While they might sound similar, they serve different purposes and are used in different scenarios.

Let’s break down what each technique means, how they differ, and when to use them.

What Is Resource Levelling?

Resource levelling is a strategy used when a team member or resource is overbooked or scheduled to work on multiple tasks at once. The main goal is to resolve these scheduling conflicts by adjusting when tasks start or end. As a result, project deadlines may shift, but the workload becomes more manageable.

This method is typically used when resource availability is limited and more important than sticking strictly to the original timeline.

For example:
Imagine your lead developer is scheduled to work on two critical tasks at the same time. With resource levelling, you reschedule one of those tasks to begin after the other is complete. This avoids overloading the developer, even if it extends the project by a few days.

What Is Resource Smoothing?

Resource smoothing, on the other hand, is used when your project deadline is fixed. Instead of changing task dates, you spread the work more evenly across the available time. The goal is to reduce peaks and valleys in workload without changing the project end date.

This technique helps improve productivity and avoid burnout, as team members won’t be overloaded on certain days and underutilized on others.

For example:
Say a content writer is assigned 30 hours of work over a five-day period. Rather than working eight hours on one day and only two on another, resource smoothing adjusts their daily schedule to around six hours per day—keeping the deadline intact while balancing their workload.

What’s the Difference Between the Two?

The biggest difference lies in what each method prioritizes.

Resource levelling focuses on who is available and adjusts the schedule accordingly. If that means pushing back the deadline to accommodate limited resources, that’s acceptable.

Resource smoothing, however, focuses on keeping the project on schedule. It redistributes effort across the available time without extending the timeline.

So, if your team is overallocated and running into conflicts, resource levelling is the way to go. If your schedule is set but the workload distribution feels uneven, resource smoothing will help you balance it out.

When Should You Use Each Technique?

Use resource levelling when:

A team member is scheduled on overlapping tasks

You’re facing resource shortages

Flexibility in deadlines is acceptable

Use resource smoothing when:

The project timeline is fixed

You want to improve efficiency and reduce overwork

Your team needs a balanced workload without changing delivery dates

Sometimes, the best approach is to use both techniques together. Start by leveling to resolve any major conflicts, then smooth out the remaining workload for a more even flow.

Example:
Suppose you’re allocated 40 hours to complete a task over 5 days. You realize you only need 30 hours. Using resource smoothing, you adjust your daily workload to 6 hours/day, freeing up time to work on other items—without changing the final deadline.

In contrast, if your schedule is tight and a resource is double-booked, resource levelling would shift deadlines to accommodate the actual availability of that person.

For the best outcome, apply resource levelling first to deal with overuse, then use smoothing to balance the remaining schedule.

Sharpening Your Resource Levelling Skills

Effectively allocating your team’s time and energy can make or break a project. Use resource levelling to prioritize, sequence, and balance work based on who’s available—and pair it with templates tailored to your industry, like IT deployment templates or marketing calendars.

Great resource planning also depends on the right tools. Project management platforms can automate much of the scheduling and visibility needed to keep work on track.

With smart planning, accurate estimates, and a solid grasp of these techniques, you’ll be better equipped to lead projects to the finish line—on time and with less stress.

Conclusion

Resource levelling is essential for resolving scheduling conflicts and avoiding team burnout. By understanding when to adjust timelines or balance workloads, you can keep your projects running smoothly and your team working efficiently—even with limited resources.
