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.

Teams deciding to build or buy
An honest comparison of running customer satisfaction & nps in-house against commissioning it.
Insight leads with a small team
Which parts of the work are worth keeping internally, and which are not.
Finance weighing fixed against project cost
The real cost of an internal capability, including the parts that never appear in a salary line.

Side-by-side

Speed: in-house is quick for simple surveys, while agencies are faster at scale
Reach: agencies cover cities and audiences that DIY panels miss
Objectivity: an independent partner reduces bias
Expertise: agencies bring specialist method and analysis skills
Credibility: boards and investors trust independent research

What goes wrong

Common mistakes in customer satisfaction & nps

Most disappointing customer satisfaction & nps 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
Surveying only the customers you can reach
Contactable, recent and happy customers answer first. If the sample is not drawn from the full base, the score flatters the business.
02
A score with no drivers
An NPS number on its own gives you the temperature, not the cause. Five to seven driver questions turn it into an action list.
03
Making the score a frontline incentive
The moment pay depends on it, staff coach customers at the point of asking and the measure stops describing reality.
04
No closed loop
Customers who raise an issue and hear nothing stop responding. Route detractors to a named owner within 48 hours.
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 customer satisfaction & nps project. Most of it costs nothing, and it saves the two weeks a re-field would take.

1
Draw the sample from the full customer base, not from the list that is easiest to reach.
2
Ask at a consistent point in the journey so the numbers stay comparable over time.
3
Add five to seven driver questions and one open verbatim to every survey.
4
Route detractors to a named owner within 48 hours and record the resolution.
5
Report drivers and response rate beside the score, every time.
6
Keep the raw data, the syntax and the tables together, so the analysis can be re-run.
7
Agree in writing who acts on each finding, and by when, before the debrief ends.
