See work breakdown structure.

work breakdown structure

The work, needed to create a product, broken down into a hierarchy. Most often, the term is related to work as well as material, and thus the work breakdown structure (WBS) is the assembly hierarchy for physical assemblies and tasks developed to show how the work is split into different operations. Done correctly, each level is a particular type of task with related material and there may be a presumption that each level is performed in a defined location. (Levels may be skipped where for instance a simple bracket goes directly to a block.)
