Tóm tắt	Means-end chain analysis explains consumer choice by linking the concrete attributes of a product to the consequences of using it and ultimately to the personal values those consequences serve. Jonathan Gutman's 1982 model proposed that consumers categorize products by the desirable consequences they deliver, and that these consequences are valued because they help attain higher-order life values, so a chain runs attribute to consequence to value. Laddering, formalized by Thomas Reynolds and Jonathan Gutman, is the interviewing technique that uncovers these chains by repeatedly asking why a feature matters until the respondent reaches the underlying values. The resulting ladders are content-coded into attributes, consequences, and values, then summarized in an implication matrix counting how often each element leads to another. Applying a cutoff to that matrix yields a hierarchical value map (HVM), a network showing the dominant attribute-consequence-value pathways for the category. The approach reveals not just what consumers want but why, providing a values-grounded foundation for positioning and advertising strategy.	The Zaltman Metaphor Elicitation Technique (ZMET) is a qualitative consumer-research method that uses images and metaphor to surface the deep, often non-conscious thoughts and feelings that drive how people relate to a brand, product, or experience. Developed by Gerald Zaltman and applied with Robin Higie Coulter, it rests on the premises that most communication is non-verbal, that thought is image-based and metaphorical, and that much of what shapes behavior lies below conscious awareness. Participants gather their own pictures representing their feelings about a topic before a lengthy depth interview, in which a trained interviewer probes the stories behind the images to move from surface metaphors to a small set of universal deep metaphors such as balance, transformation, connection, and journey. Across participants, the elicited constructs and their connections are combined into a consensus map of the shared mental model. Zaltman's 2003 book How Customers Think and the 1995 Journal of Advertising Research article with Coulter set out the technique and its rationale. ZMET aims to hear the voice of the customer in the visual, metaphorical terms in which people actually think.
