A new project manager finds the work has been decomposed to the lowest level, but believes some useful information is missing. What should the project manager review?

The WBS dictionary provides detailed information for each WBS component, including work package descriptions, deliverables, acceptance criteria, assigned organization, schedule milestones, and cost estimates. If the project manager feels useful information is missing despite the WBS being decomposed, the WBS dictionary is the primary document to consult for these specifics. The requirements traceability matrix links requirements to deliverables but doesn't detail work package specifics. The project charter and scope statement define the overall project and its boundaries but not the detailed work package information. Business requirement documents (BRDs) define stakeholder needs but are not the source for detailed WBS component information.
