Effective resource management is crucial for the successful delivery of large-scale engineering, procurement, and construction projects. Two of the most widely used techniques in project scheduling are Resource Leveling and Resource Smoothing. Understanding these techniques and applying them correctly can significantly improve project objectives while maintaining efficiency.
What is Resource Leveling?
Resource Leveling is a scheduling technique used when resource constraints, such as limited supply or availability, impact a project's timeline. In this method, activities' start and finish dates are adjusted to ensure that resource usage is balanced with available supply.
Key Characteristics:
Adjustments are made to align resource usage with availability, which may result in delays or the extension of project timelines.
This technique is often necessary when shared or critical resources are only accessible at certain times, are over-allocated, or must be maintained at a steady usage rate.
A significant drawback is that Resource Leveling can change the original critical path, usually increasing the project's duration.
When to Use Resource Leveling
Resource Leveling is an essential strategy when dealing with scarce or overbooked resources. In situations where specific skilled labour or specialized machinery is needed but available in limited supply, scheduling adjustments become necessary to align with these constraints. However, project managers must remain vigilant about the potential impact on the critical path, as such adjustments could extend the overall project timeline.
What is Resource Smoothing?
Unlike Resource Leveling, Resource Smoothing is a technique used when the focus is on meeting predefined resource limits without changing the project's critical path. Here, activities are adjusted within their available float, ensuring that the project completion date remains unchanged.
Key Characteristics:
Activities are delayed only within their free and total float, meaning there is no impact on the overall timeline.
The critical path remains the same, and project deadlines are not affected.
A downside is that Resource Smoothing may not fully optimize all resource usage.
When to Use Resource Smoothing
Resource Smoothing is ideal for projects where staying on schedule is imperative, and there is some flexibility in the allocation of resources. It is used to improve resource efficiency without sacrificing the project completion date. This method is especially beneficial for keeping tight control over critical deadlines while still managing resource allocation intelligently.
Choosing the Right Technique
The choice between Resource Leveling and Resource Smoothing depends on the project’s specific requirements and constraints:
Use Resource Leveling when resources are a hard constraint and delays are unavoidable.
Use Resource Smoothing when project timelines are non-negotiable, and there is some leeway in managing resources.
Conclusion
Both Resource Leveling and Resource Smoothing have their advantages and limitations. Project managers should evaluate the project's goals, resource constraints, and timeline flexibility to choose the appropriate technique.
