WBS Dictionary

Correct Answer: Request updated information from the team member responsible for the entry

The best course of action when a WBS Dictionary entry lacks critical cost estimation data is to 'Request updated information from the team member responsible for the entry'. This is because, in project management, decisions should be based on accurate and complete information. It is the responsibility of the team member who created the entry to provide this data. Proceeding without it('Proceed with the project without updating the cost estimation data') or making assumptions('Add the cost estimation data based on personal assumptions') can lead to inaccurate project scope, costs, and outcomes. Also, revising the WBS Dictionary and starting the project from scratch is time-consuming and impractical unless there are severe errors in the WBS Dictionary that may affect the success of the project.

Correct Answer: Evaluate the impact of the change, and if approved, include it in the WBS Dictionary

In a project, any modification demanded must be assessed for its impact on the project's scope, schedule, cost and resources. Hence the best approach when a last minute requirement change arrives, according to best practice in project management, is to 'Evaluate the impact of the change, and if approved, include it in the WBS Dictionary'. The answer 'Include the change without evaluating its impact' is wrong because it could disrupt the project by not considering the potential influences this change could bring. 'Reject the change request as the project is about to start' is also not a good choice, as it’s assuming preemption and does not advocate for conducting a thorough evaluation of the changes, which can sometimes lead to the improvement of the project As for 'Request assistance from another project team for evaluation', while getting opinions from other teams could be useful occasionally, the ultimate responsibility for examining the change and deciding its addition to the WBS Dictionary rests within the project team and primarily with the project manager.

Correct Answer: Include information about work packages, control accounts, and deliverables

The creation of the Work Breakdown Structure (WBS) Dictionary, an important part of Project Management, involves clearly detailing all components of the project. Appropriate information, like work packages, control accounts, and deliverables, should be included to provide a comprehensive view of the project. Answer 'Create the WBS Dictionary after completing the project' is incorrect because the WBS Dictionary is considered an essential project planning tool and should be developed at the beginning of the project, not after finishing it. Similarly, 'Only include work packages in the WBS Dictionary' is a limited perspective, because, aside from work packages, control accounts and deliverables are also key components. Lastly, 'Add every detail about tasks and milestones, regardless of relevance' is also incorrect. While it's important to be thorough, not every detail is necessarily relevant or useful. Overloading the WBS Dictionary with excessive information could make it less effective and harder to use.
