Question 01
What’s the difference between a satisfaction survey and NPS?
NPS is a single metric: on a 0–10 scale, it measures how likely a customer is to recommend you. A satisfaction study gives you the full picture. It includes NPS and other metrics, and covers service, price, turnaround times, quality and every touchpoint. That’s what explains why your score is where it is, and where to act. In practice, NPS is usually one of the metrics tracked in the program.

Question 02
How often should we measure satisfaction?
It depends on how many interactions you have and how quickly the experience changes. Service and touchpoint surveys work well on an always-on basis, right after each interaction. Relationship satisfaction is usually measured in quarterly, twice-yearly or annual waves. What matters most is keeping the same interval and the same core questionnaire, so waves can be compared.

Question 03
How many people do we need to survey?
It depends on the precision you need and how many groups you want to analyze separately. For a large population, about 400 interviews give a margin of error of 5 percentage points, and about 1,070 give 3 points, at 95% confidence. If you want to compare locations, regions or channels, each group needs a large enough sample. The sample size calculator on our site gives you a first estimate.

Question 04
Do you use our customer list or recruit respondents?
Either works. Most satisfaction studies use the company’s own customer list, since those are the people who actually had the experience. To hear from competitors’ customers, prospects or people you have no contact details for, Checon recruits respondents through its research panel, social media and, when needed, paid ads.

Question 05
How is our customer data protected?
The data you share is used only for the research, with access limited to the project team, and handled in line with Brazil’s data protection law (LGPD). Results are reported in aggregate, and a customer is only identified to you with their consent, as with low-score alerts. Our processes follow the ISO 20252 standard.

Question 06
How long until we see the first results?
It depends on the data collection method, the sample size and the questionnaire design. The proposal includes a full timeline, from discovery to the first presentation. After the first wave, the next ones are faster, because the questionnaire, dashboard and reports are already in place.

Question 07
Can we start with one wave and turn it into a tracking program later?
Yes, and it’s a smart way to start. The first wave is your baseline: it shows where you stand and tests the questionnaire. Later waves use the same methodology and start showing the trend and the impact of your actions.

Question 08
How much does customer satisfaction research cost?
It depends on the audience, the data collection method, the number of interviews and how often you run waves. That’s why every proposal is tailored. Tell us what you need to track and we’ll send a proposal with scope, timeline and pricing.
