Quick Definition:
Resource Leveling is a technique used to adjust the project schedule when resources are over-allocated, often resulting in a delay to the project’s end date. Resource Smoothing is a technique that adjusts activities within their float to ensure resources do not exceed predefined limits, without delaying the project’s end date.
Leveling vs. Smoothing
| Feature | Resource Leveling | Resource Smoothing |
|---|---|---|
| Goal | Resolve over-allocation | Even out resource usage |
| Impact on End Date | Can delay end date | Does NOT delay end date |
| Constraint | Resource availability | Project end date |
