What is the function of a decision matrix?

A decision matrix is a valuable tool used in the decision-making process to systematically evaluate and prioritize options based on specific criteria. It helps individuals or teams compare various alternatives in a structured manner, allowing for a clear visual representation of how each option measures up against the established criteria.

In a decision matrix, options are typically listed along one axis while criteria are listed along the other. Each option is scored based on how well it fulfills each criterion, and this scoring can be weighted according to the importance of each criterion. This approach enables decision-makers to identify the most favorable option by analyzing quantitative data rather than relying solely on subjective opinions, which enhances objectivity and clarity in decision-making.

The other choices do not accurately reflect the core function of a decision matrix. For instance, documenting team members' opinions focuses on gathering subjective feedback rather than systematic evaluation. Creating a timeline for implementation pertains more to project management than to the actual decision-making process. Summarizing past decision outcomes is about reviewing past actions rather than evaluating current choices. The decision matrix's primary role is in organizing and prioritizing options for current decisions, making it an essential tool for effective problem-solving.
