Where you test: home use test or central location test
These are the two classic formats of the consumer test, and they are not interchangeable: they answer different questions, so picking the wrong one is the most expensive way to end up with a number you cannot use.
The product is the same. What changes is the place, and the place decides what you get to see.
Both formats, criterion by criterion
A home use test (HUT) happens at home; a central location test (CLT) happens at a test venue. The acronyms are the ones the industry uses, and behind each one there is a different split between what is controlled and what is allowed to happen.
The row that usually decides is the last one: each format pays its price somewhere.
| Criterion | HUT · at home | CLT · at a venue |
|---|---|---|
| In one sentence | Consumers take the product home and use it as they would use any other: when they feel like it, with whatever they normally have alongside it, and more than once. | Samples are tasted at a central location, coded, at the same temperature, in the same format and in balanced order. |
| How long | Days or weeks: long enough for palate fatigue to show and for repeat consumption to be seen. | A single session. Each consumer tries several samples on the same day. |
| What it measures well | Acceptance in real use, fit with the consumption occasion, repeat purchase intent. It is the only format that sees what happens once the novelty wears off. | Fine comparison between products: everything that is not the product is held equal, so the difference that shows comes from the product. |
| Weak point | You do not control how it was prepared or what it was eaten with: the crockery, the oven and the fridge are theirs. | It is an artificial setting: nobody eats five yoghurts in a row at a test venue. |
First the venue, then the home
Chaining the two is more common than it looks, and the order matters: each format does one part of the job well, and one of the two is cheaper to run first.
The CLT ranks them
Several prototypes, the same venue and the same conditions for every one of them. Comparing is what this format does best: it is where the finalist comes from, and where the rest are dropped before more money goes into them.
The HUT validates
The finalist goes home, where the problems of consumption occasion and palate fatigue show up — the ones no test venue can reveal. In that order it costs less than the other way round.
Reformulation: repeat consumption →
The format says where you test. What you ask is the other half of the decision.
Acceptance, preference or comparison against a competitor are chosen in the test design, and that is where what you will be able to claim gets settled. Getting the room right does not fix the wrong question.
