PMI Professional in Business Analysis (PMI-PBA) — Question 79

A business analyst needs to estimate the effort associated with project requirements. However, the lack of detail is concerning.
What technique could the business analyst use to help alleviate this concern?

Answer options

• A. Decomposition model
• B. Swimlane diagram
• C. Business analysis work plan
• D. Context diagram

Correct answer: A

Explanation

The Decomposition model is effective for breaking down complex requirements into smaller, more manageable parts, thereby providing clarity and detail. The other options, while useful in different contexts, do not specifically focus on estimating effort or clarifying vague requirements as effectively as the Decomposition model does.
