CAPM Practice: Demonstrate an understanding of common problem-solving tools and techniques

During project monitoring, problem-solving tools help analyze performance data. A Pareto chart applied to quality review data identifies priority defects — directly supporting corrective action decisions. The other options are planning tools, not problem-solving tools used during monitoring.

**Why not A:** A project charter is an initiation document used to formally authorize the project. It is not a problem-solving tool and is not used during project monitoring. The charter establishes the project's existence, not diagnose performance issues.

**Why not B:** A work breakdown structure (WBS) is a planning tool used to decompose project scope into manageable deliverables. It is created during planning, not used as a problem-solving tool during monitoring. The WBS defines what work needs to be done, not where problems exist.

**Why not D:** A RACI chart is a responsibility assignment matrix used to clarify roles and responsibilities during planning. It assigns who is Responsible, Accountable, Consulted, and Informed for each task, but it is not a problem-solving or data analysis tool used during monitoring.
