This method adjusts the project schedule to address situations where resources are over-allocated or when there are constraints on resource availability.
The primary goal of resource leveling is to balance the demand for resources with the available supply. When multiple tasks require the same resource simultaneously, conflicts arise that can lead to delays, burnout, or quality issues. Resource leveling addresses these problems by redistributing work or adjusting task schedules.
Project managers implement resource leveling by analyzing the project schedule and identifying periods where resources are overcommitted. They then make adjustments such as delaying non-critical tasks, extending task durations, or splitting tasks to spread work more evenly. This process often results in a longer project duration but ensures realistic workload distribution.
Key characteristics of resource leveling include maintaining task dependencies while shifting activities within available float or slack time. When insufficient float exists, the critical path may extend, pushing out the project completion date. This trade-off between schedule and resource optimization is a fundamental consideration.
Resource leveling differs from resource smoothing, which attempts to optimize resource usage while keeping the project end date fixed. Resource leveling prioritizes resolving over-allocation even if it means extending the timeline.
Common scenarios requiring resource leveling include shared team members across multiple projects, limited specialized equipment, seasonal availability constraints, and budget limitations affecting staffing levels.
Modern project management software automates much of the resource leveling process, allowing managers to quickly identify conflicts and evaluate different leveling scenarios. However, human judgment remains essential for making final decisions about which tasks to adjust and how to communicate changes to stakeholders.
Effective resource leveling contributes to sustainable team performance, realistic schedules, and improved project outcomes.

What is Resource Leveling?
Resource leveling is a project management technique used to resolve resource conflicts by adjusting the project schedule. When resources (such as team members, equipment, or materials) are over-allocated or assigned to multiple tasks simultaneously, resource leveling redistributes work to ensure resources are used efficiently and not overburdened.
Why is Resource Leveling Important?
Resource leveling is critical for several reasons:
• Prevents burnout: Ensures team members are not assigned more work than they can handle • Maintains quality: Overworked resources often produce lower-quality outputs • Realistic scheduling: Creates achievable timelines based on actual resource availability • Cost control: Helps avoid overtime costs and the need for additional resources • Stakeholder satisfaction: Produces more reliable delivery dates
How Resource Leveling Works
The resource leveling process typically involves:
1. Identify over-allocation: Review the resource histogram or workload chart to find resources assigned beyond their capacity
2. Analyze task dependencies: Determine which tasks have flexibility (float/slack) and which are on the critical path
3. Apply leveling techniques: • Delay non-critical tasks to periods when resources are available • Split tasks into smaller segments • Extend task durations • Reassign tasks to other available resources
4. Review the adjusted schedule: Ensure the changes resolve conflicts and the project remains viable
Key Characteristics of Resource Leveling
• Often extends the project timeline - This is the primary trade-off • Focuses on resource constraints - Priority is given to resolving over-allocation • Uses float/slack time - Non-critical activities are typically adjusted first • May change the critical path - Schedule adjustments can shift which path is longest
Resource Leveling vs. Resource Smoothing
Understanding the difference is essential for the exam:
• Resource Leveling: Resolves over-allocation; can extend the project end date • Resource Smoothing: Optimizes resource usage; cannot extend the project end date; works within existing float
Exam Tips: Answering Questions on Resource Leveling
1. Remember the key outcome: Resource leveling typically results in a longer project duration. If a question asks about the consequence of resource leveling, schedule extension is usually the answer.
2. Know the trigger: Resource leveling is applied when resources are over-allocated or when there are resource conflicts.
3. Distinguish from smoothing: If the question states the end date cannot change, the answer is likely resource smoothing, not leveling.
4. Float is your friend: Questions may reference using slack or float time - this is a primary mechanism in resource leveling.
5. Watch for scenario questions: Look for keywords like "team member assigned to multiple tasks," "resource conflict," or "over-allocation" as indicators that resource leveling is the solution.
6. Critical path awareness: Resource leveling may affect the critical path. Be prepared for questions about how leveling impacts project constraints.
7. Tools and inputs: Resource leveling uses the project schedule, resource calendars, and resource requirements as inputs. Project management software often performs this calculation automatically.
Sample Exam Question Pattern
"A project manager notices that a developer is assigned to three concurrent tasks during week four. What technique should be used to address this situation?"
The answer would be Resource Leveling because there is a resource over-allocation that needs resolution.
