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 mystery shopping 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.

01

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. scorecards, outlet rankings, photo and audio evidence)
  • Can I see a sample report?

What goes wrong

Common mistakes in mystery shopping

Most disappointing mystery shopping 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

    A scorecard that measures everything

    Eighty observation points produce a number nobody can act on. Score the 20–25 behaviours the service standard actually asks staff to perform.

  • 02

    Shoppers who do not look like the customer

    A shopper outside the outlet's customer profile is treated differently, and the score then measures that difference rather than the standard.

  • 03

    Using the results punitively

    Once scores drive penalties, staff start identifying shoppers and managing the visit. Pair every report with a coaching plan.

  • 04

    Calling a single visit a verdict

    One visit captures one staff member on one shift. Spread visits across days, shifts and weekends before ranking anybody.

  • 05

    Measurement used to punish rather than improve

    Once results drive penalties, the people being measured start managing the measurement. Pair every report with a coaching plan.

  • 06

    Comparability broken between waves

    A changed scorecard, outlet list or definition makes wave two uncomparable with wave one. Freeze the instrument and revise it only at a planned annual review.

Run through this before sign-off

Your checklist before you brief anyone

A working sequence for a mystery shopping project. Most of it costs nothing, and it saves the two weeks a re-field would take.

  1. 1

    Build the scorecard from the published service standard, with a maximum of 25 observable items.

  2. 2

    Profile-match shoppers to the outlet's real customer, including age, language and spending level.

  3. 3

    Schedule at least three visits per outlet across different days and shifts.

  4. 4

    Require photographic or audio evidence for every scored item that allows it.

  5. 5

    Calibrate all scorers on the same two pilot visits before the wave opens.

  6. 6

    Freeze the instrument so the next wave stays comparable with this one.

  7. 7

    Agree in writing who acts on each finding, and by when, before the debrief ends.
