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.

Project managers running the study
A working sequence for a mystery shopping project, from brief through field to debrief.
In-house teams doing it themselves
The quality controls an agency would apply, written so that you can apply them yourself.
Reviewers signing off a vendor plan
Read it as an audit list against the proposal currently on your desk.

The 12-step checklist

Write down the business decision
List the information gaps
Define the target audience precisely
Choose cities and the urban/rural split
Set the sample size and key segments
Pick the method (in-store audits, phone mystery calls, digital mystery shops, compliance checks)
Agree languages and translation
Draft and pilot the questionnaire or guide
Agree quality-control checks
Set the timeline and milestones
Define deliverables and format
Plan the debrief and next actions

Why the order matters

Each step constrains the next. Changing the audience late, for example, can reset sampling, cost and timeline.

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
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.
06
Field evidence that cannot be audited
Without photographs, timestamps and supervisor sign-off, a disputed score becomes one person's word against another's.

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
Build the scorecard from the published service standard, with a maximum of 25 observable items.
2
Profile-match shoppers to the outlet's real customer, including age, language and spending level.
3
Schedule at least three visits per outlet across different days and shifts.
4
Require photographic or audio evidence for every scored item that allows it.
5
Calibrate all scorers on the same two pilot visits before the wave opens.
6
Calibrate every auditor or interviewer against the same two pilot cases before wave one.
7
Agree in writing who acts on each finding, and by when, before the debrief ends.
