What element must be present in a decision matrix?

A decision matrix is a tool used to evaluate and prioritize different options based on predetermined criteria. The essential element of a decision matrix is the criteria for ranking, as these criteria provide the basis for assessing how well each option meets the necessary requirements and goals.

Criteria can include various aspects such as cost, functionality, feasibility, and any other relevant factors that influence the decision-making process. By establishing these criteria, users can objectively compare and rank the options under consideration, making sound decisions based on quantifiable data rather than subjective judgment.

The other elements listed, such as design specifications, detailed documentation, and visual representations, may be valuable in the overall design process, but they do not form the foundational structure of a decision matrix. The criteria for ranking are what enable the matrix to function effectively as a decision-making tool.
