What best describes a decision matrix?

• A. A chart showing time series data
• B. A table with alternatives in the rows and various impact factors in columns
• C. A narrative comparison of options
• D. A list of pros and cons

Answer: (B)

A decision matrix is a structured tool for comparing options by evaluating them against a set of criteria, often with weights and scores. It organizes alternatives in rows and the evaluation factors in columns, then you rate how well each option meets each criterion and compute an overall score to guide the choice. This makes the comparison explicit and quantitative, rather than relying on intuition alone.

This is why the best description is a table with alternatives in the rows and various impact factors in columns. A time-series chart shows data over time, not a multi-criteria comparison. A narrative comparison or a simple list of pros and cons lacks the systematic scoring and weighting that a matrix provides.
