What is Evaluation of Alternatives?
In stage three, the consumer evaluates the consideration set on the attributes they consider important. Marketers care about the decision rule the consumer uses. Compensatory rules (weighted-additive) let a strong score on one attribute offset a weak score on another. Non-compensatory rules — conjunctive (must meet a minimum on every attribute), lexicographic (rank by most important attribute, then second), elimination-by-aspects — kill brands that fail on a critical dimension. High-involvement, high-risk decisions tend to use compensatory rules; quick low-involvement decisions tend to use non-compensatory shortcuts.
How Evaluation of Alternatives actually works
The framework breaks down into the following moving parts. Knowing what each piece is — and what it is not — is what separates a B-grade answer from an A-grade answer in a written assignment.
- List the attributes the consumer considers (the evoked set)
- Determine relative importance weights
- Determine each brand's perceived score on each attribute
- Apply the decision rule (compensatory or non-compensatory)
- Move from consideration set to choice set to purchase
- Marketers shape weights, scores, AND the rule itself
A worked example: Toyota Camry buyers
Toyota Camry buyers typically use a compensatory rule: reliability (high weight), fuel economy (medium), driving fun (low). Camry scores 9, 8, 4 on a 10-point scale, summing to a high weighted total. A Mazda 6 might score 7, 7, 9 — sum is similar but the buyer's weights favor Toyota. A purely lexicographic buyer who only cared about driving fun would pick the Mazda. Marketers can either raise their score on a heavy attribute, or argue for a different weighting — both are legitimate evaluation-stage moves.
Don't lose marks for these
- Assuming buyers always use compensatory rules
- Marketing on the wrong attribute (one with low weight)
- Ignoring elimination-by-aspects: a single critical failure kills the brand
How to use this on the exam
Score-maximizing moves
- Name the decision rule explicitly
- Distinguish compensatory from non-compensatory
- Show how marketing can shift attribute importance, brand scores, OR the decision rule
When to use Evaluation of Alternatives (and when not to)
Use Evaluation of Alternatives when your assignment asks you to analyze, structure, or recommend — and when you have at least two data points to populate every cell of the framework. Skip it when the question is asking for a numerical answer or a single recommendation, since Evaluation of Alternatives is a structuring tool, not a calculator.
