Laddering

Origin. Reynolds and Gutman (1988); means-end chain theory; qualitative market research.

Mechanism. Elicits the chain from concrete attributes through functional consequences to abstract values. Repeated "why" questions climb the ladder of abstraction, revealing what product attributes ultimately mean to the user.

Procedure. Start with a concrete attribute or behavior. Ask "why is that important to you?" Record the answer. Ask "why is that important?" of the answer. Continue until reaching a terminal value (the interviewee says "it just is" or gives a fundamental human value). The chain from attribute to value is the ladder.

Applies to. Product positioning, understanding user motivation, identifying which features matter and why.

Limitations. Interviewees rationalize post-hoc; the stated chain may not reflect actual motivation. The interviewer's "why" can feel interrogative and produce defensive responses. Use "what does that give you?" as a softer alternative.
