Why each option
A WBS best justifies itself to skeptical managers by demonstrating that it prevents overlooked work and clarifies resource requirements for the project.
A WBS decomposes the total project scope into smaller, manageable work packages, ensuring every deliverable and task is explicitly documented, which directly prevents work items from being overlooked or falling through the cracks during execution.
Stating the WBS is required only on very large projects is an incorrect and artificially limiting claim that would not persuade managers to adopt it as a standard practice.
Conditioning WBS creation on the project manager's available time frames it as optional and low-priority, which undermines its value and provides no compelling business case for adoption.
By breaking the project down into detailed work packages, the WBS makes it possible to identify and assign the specific human, material, and financial resources required for each component, giving managers visibility into resource planning.
While the WBS can inform risk identification by clarifying scope boundaries, the risk register and risk assessment processes are the primary tools for determining and managing project risks.
