In short
Fragrance consumer research gathers reactions from people who resemble the intended buyer, to inform a specific decision. At small scale it can reveal problems, confusions and strong dislikes, and it can help you choose between a few versions. It cannot predict sales or tell you what a market prefers. Used with that limit in mind, even a dozen properly run responses can be useful. In Level 8 you met the methods. Here you apply them to a brief.
What you will learn
- Write a research question that informs one decision
- Design a small test without leading participants
- Report what the sample can support
Before this lesson: Mods and Sample Tracking: Study Guide
Start with the decision
A good research question is tied to something you will do differently:
- Weak: "Do people like it?"
- Better: "Between mods B and C, which is more often described using the words the brief wanted, and does either provoke strong dislike?"
Write what you will do under each outcome. If no result would change your plan, do not run the test.
Choosing a test
| Question | Approach | Practical scale |
|---|---|---|
| Is anything wrong? | Open reactions, on strips | 5 to 8 people |
| Which of two? | Paired preference with reasons, order balanced | 15 to 30 people |
| Does it fit the brief's words? | Rate agreement with words, after open reaction | 15 to 30 people |
| Can they tell the difference? | Triangle test | See the sample-size lesson |
| Will it succeed in the market? | Beyond small-scale research | Commission a professional study |
Reducing bias
- Recruit away from friends. If you cannot, say so in your report.
- Use neutral codes. Avoid names, packaging and your story.
- Vary the order. Half see A first, half see B first.
- Ask open questions first. Then ask about any specific words.
- Stay out of it. Your face can lead them, so try to use written forms.
- Allow time. Take responses at a set time, and a later one if the drydown matters.
The Lab's consumer testing guide and your bias lesson give the wider list.
Consent and safety
Test on strips unless the product has been properly assessed for skin use. Tell people what they are smelling in general terms, that it is optional, and how their answers will be used. Do not gather personal data that you don't need. Keep the materials well away from anyone who tells you they have a fragrance allergy or asthma. The ethics lesson in the research track goes further.
A worked report, with invented numbers
Twenty adults from a local workplace, not selected to represent any market, compared mods B and C on strips at 15 minutes, order balanced, on November 2. 13 preferred C and 7 preferred B. Two said C was "too sweet". No one rated either as unpleasant. A 13-to-7 split in 20 people could plausibly occur by chance. We treat it as a weak indication toward C, and we will address the sweetness before we run a second test.
Notice what it says about the sample and about chance. If 10 were expected under no preference, 13 is not much of a departure with so few people. The calculation is in the research track.
Practical exercise: A small test for one decision
- Choose a decision you need to make about two versions of a fragrance.
- Write the question, plus what you would do under each outcome.
- Write a one-page plan: participants, codes, order, questions, consent and safety.
- Run it on strips with at least eight people if you can, and collect the responses in writing.
- Write a short report in the style above, and include a sentence that begins, "This does not show".
You have done this well if your decision was written first, your report describes the sample honestly, and you acted on it in the way you said you would, or explain why not.
Common mistakes
- Asking friends and calling them consumers. Describe them for what they are.
- Telling your story first. Reactions will follow the story.
- Reading a small split as a verdict. Check whether chance could explain it.
