Which of the following statements best describes the purpose of a matrix diagram?

A matrix diagram is a quality tool used to show relationships between two or more sets of information. In software quality engineering, it can compare requirements to test cases, defects to root causes, risks to controls, stakeholders to requirements, or process steps to responsibilities. The purpose is to make relationships visible so teams can analyze coverage, dependencies, gaps, and strength of association. Ranking priorities and reaching consensus is more closely related to prioritization tools or nominal group techniques. Showing problems with the greatest improvement potential is often done with Pareto analysis. Showing gaps between current and desired performance may involve gap analysis. Therefore, the matrix diagram’s main purpose is systematic comparison between information sets.
