Glossary: Resource load / Resource allocation

A resource's load is the amount of effort it is assigned to do at various times throughout the project. If a resource is assigned at more than 100% of its availability all at once, it is said to be "overloaded" or "overutilized". Resource leveling tries to alleviate overload of resources. You can see each resource's load by turning on the resource allocation graphs

in the resource timeline.
