Scope Decomposition

Correct Answer: Decompose the work breakdown structure into manageable pieces.

The best action when a work breakdown structure becomes unmanageable due to its size and detail is to decompose it into manageable pieces. Decomposition is the act of breaking down complex tasks into simpler, more manageable parts, thus ensuring clarity and easier management. Ignoring the issue and continuing with the project execution isn't recommended because the project's management might become too overwhelming due to the complexity of the work breakdown structure. Removing unnecessary tasks might not be the best solution if all tasks are essential to the project's completion. Assigning a team member to manage the work breakdown structure may not resolve the issue if the structure remains overly complex and detailed. The best course of action is to simplify the structure through decomposition.

Correct Answer: Begin the process of Scope Decomposition.

The best course of action when the scope of a project is too broad and undetailed is to begin the process of Scope Decomposition. Scope Decomposition allows for a typically large project scope to be broken down into smaller, more manageable parts. It improves the understanding, estimating, and managing of the project. The other answers are wrong because, Keeping going as it is and hoping that enough detail would appear during execution may lead to mismanagement of the project, confusion, and ultimately, failure. Scraping the project and starting again can lead to unnecessary cost and time wastage. Finally, delegating the task of understanding the scope to a team member may not solve the problem if the scope is not adequately defined and detailed and might lead to confusion and misinterpretation of the project requirements.

Correct Answer: Work Breakdown Structure (WBS)

The Work Breakdown Structure (WBS) is a technique used during scope decomposition to break down the project scope into smaller, more manageable components. This hierarchical decomposition of the project scope facilitates better planning, control, and management of the project. The WBS provides a structured approach to defining and organizing the total scope of a project, making it easier to assign responsibilities, allocate resources, and monitor progress. The other options mentioned, such as Work Breakdown Component (WBC), Project Breakdown Structure (PBS), and Scope Breakdown Design (SBD), are not standard terms or techniques used in project management for scope decomposition.
