Evaluative Research
Research to check whether what you built is any good.
Definition

Craft convention. True because the industry converged on it. Breaking it costs familiarity, not correctness.

Commonly confused with
Close neighbours that get substituted for each other. The difference is stated first, then the condition that picks one over the other.
Generative Research
TermExploratory work that surfaces needs, context and opportunities.
Key difference
Generative research runs before you know what to build and produces direction. Evaluative research runs against something that exists and produces judgement. The mistake is evaluating a decision you have not made yet.
Use Evaluative Research when
- There is a design, prototype or live product to judge.
- The output is a list of problems and their severity.
- The decision is whether to ship, change or revert.
Use Generative Research when
- The problem is not settled.
- You are deciding what is worth building.
- The output feeds framing, not a fix list.
