Reader intent

Who this guide is for

Three readers arrive here with different problems. Each should be able to act on this page without reading all of it.

Buyers running a vendor call
Questions that reveal whether an agency has actually run product & concept testing at your scale.
Procurement scoring proposals
A way to score the answers rather than the presentation.
First-time commissioners
What good answers sound like, so you can tell them from merely fluent ones.

The 10 questions

Do you run fieldwork in-house in my cities?
How do you verify interviews?
How will you design the sample?
Which languages do you work in?
How do you handle translation?
How is data secured, and are you DPDP compliant?
Who leads the project day to day?
Who writes the report?
What exactly will I receive? (e.g. go/no-go scores, optimisation guidance, volume forecasts)
Can I see a sample report?

What goes wrong

Common mistakes in product & concept testing

Most disappointing product & concept testing studies fail for reasons that were visible in the design, not in the fieldwork. These are the ones we see most often, and what to do instead.

01
Order effects left uncontrolled
Sequential testing without rotation makes the first product look better. Rotate, or run monadic cells and accept the larger sample.
02
Testing only with current users
Your own users rate the product kindly and tell you nothing about the switchers who would grow the brand.
03
No benchmark in the test
A score of 7.2 means nothing without the market leader scored under the same conditions by the same respondents.
04
Conditions that do not match the occasion
Tasting a beverage warm in a hall, or trying a product without its packaging, tests something other than the thing you plan to sell.
05
Significance claimed on thin bases
A gap between two sub-groups of forty respondents is rarely real. Agree the minimum reportable base before field and grey out everything below it in the tables.
06
A questionnaire nobody piloted
Routing errors, ambiguous scales and a 35-minute runtime are cheap to find in a 30-interview pilot and expensive to find in the full dataset.

Run through this before sign-off

Your checklist before you brief anyone

A working sequence for a product & concept testing project. Most of it costs nothing, and it saves the two weeks a re-field would take.

1
Choose monadic or rotated designs and write the rotation into the field instructions.
2
Include the current market benchmark in the test, scored the same way.
3
Recruit both users and non-users, with a quota on each.
4
Standardise serving, storage and usage conditions across every location.
5
Set the action standard — the score at which you proceed — before fieldwork begins.
6
Agree the minimum reportable base before fieldwork, and hold the line in the tables.
7
Agree in writing who acts on each finding, and by when, before the debrief ends.
