3-About Initials and Grouping
MS Project defines three basic types of resources.
Work Resources – include people and equipment. For these, work is calculated in terms of time based units like, hrs, days, weeks, etc.
Material Resources – include materials. These get consumed in the progress of the project.
Cost Resources – These neither have an associated work nor get consumed. E.g., travelling costs, training costs, etc.
For a task like Painting –
Painter is the Work (People) Resource
Paintbrushes and tools are the Work (Equipment) Resource
Paint is the Material Resource
Travel costs for the Painter is the Cost Resource
