Utility-Matrix Analysis
Utility-Matrix Analysis is a decision framework that systematically evaluates options by assigning utility values and probabilities to outcomes, then calculating expected values to rank alternatives.
THE IDEA
The Eight Steps of Utility-Matrix Analysis
Step 1: Identify the options and outcomes to be analyzed.
Step 2: Identify the perspective of the analysis.
Step 3: Construct a utility matrix.
Step 4: Assign a utility value of 0 to 100 (unless dollars are used) to each option-outcome combination—each cell of the matrix—by asking the Utility Question: If we select this option, and this outcome occurs, what is the utility from the perspective of …? There must be at least one 100 unless dollars are used.
Step 5: Assign a probability to each outcome. Determine or estimate this probability by asking the Probability Question: If this option is selected, what is the probability this outcome will occur? The probabilities of all outcomes for a single option must add up to 1.0.
Step 6: Determine the expected values by multiplying each utility by its probability and then adding the expected values for each option.
Step 7: Determine the ranking of the alternative options.
Step 8: Perform a sanity check.

When to use it
Evaluating investment options under uncertain economic conditions
Comparing different marketing strategies with varying risks and rewards
Choosing between project proposals based on expected outcomes and probabilities
Making resource allocation decisions in operations management
FROM THEORY TO EVERYDAY LIFE
In practice
Marketing Strategy Decision
A company compares two marketing strategies: Option A (aggressive campaign) and Option B (conservative campaign). Outcomes are high demand (A: 0.6 probability, B: 0.5) or low demand (A: 0.4, B: 0.5). Utilities: A-high: 100, A-low: 20; B-high: 70, B-low: 40. Expected utilities: A = 0.6100 + 0.420 = 68; B = 0.570 + 0.540 = 55. Option A is preferred.
A MOMENT TO REFLECT
Put it to work.
Whose preferences should the utility values represent, and how can you assign them consistently enough to compare the options?
What methods can you use to estimate probabilities accurately when historical data is unavailable?
What kind of sanity checks would you perform after calculating expected values to ensure the analysis is robust?
