Work Breakdown Structure (WBS)
When planning a project, a simple way of discovering the tasks to be performed by starting at the higher level and then breaking things down one level at a time.
For example a software project will start with requirements, design, etc. The Design is of the architecture, verification, etc. The architecture is of user-interface, database manager, etc. And so on.
