There are two types of resources: material and work.
A material resource is a consumable resource, such as gasoline, cement, or a truck. Material resources are commonly defined as resources that are not people; however, while often true, this is not always the case. Material resources can be machines, raw materials, places, vehicles, and so on.
A work resource is a person who is assigned or allocated to a task in a task plan and makes progress against that task at a defined rate.
Material resources are defined by setting the Type column in the Gantt view to Material. Once defined, you can use the Material Label column to describe the material resource.
