- Decomposition: The process of breaking down the work from deliverables to detailed work packages and assigning unique work identifiers in order to allocate to team or different resources. The decomposition is done across deliverables part of different phases in a project.

- Scope Baseline: The components include –
> Scope Statement
> WBS Dictionary

Once the scope is base lined, any changes will go through a change control process. While WBS has the hierarchical breakdown of deliverables, WBS Dictionary has additional details like description, code of account identifier among others.
