Comparing Uses for Work Breakdown Structure Components

Before you decide which work breakdown structure components to use, make sure that you understand the differences between these components.

Naming Conventions

The information on this page uses the Deltek default names for work breakdown structure and other elements, including "project," "phase," "task," "organization," "labor code," and "employee."

However, you can change these names to meet your business requirements. For example, you might make changes such as these:
Level Default Label Alternate Ex. 1 Alternate Ex. 2
One Project Client Matter
Two Phase Engagement Task
Three Task Event Deliverable

Once you make naming changes, these changes flow through the Deltek user interface and the online help.
