Customers & Research

Should I do customer interviews live over a call, or is survey data good enough at the start?

A starting point

At the start, surveys are a trap because they let you skip the messy, contradictory human detail where the real insight lives. You cannot ask a follow-up to a checkbox, and you will read your own hopes into the numbers. As a starting point, do live conversations until you can predict what people will say, then use surveys later to size something you already understand.

Why we picked it This is Steve Blank, the person who coined the phrase, making his core argument in a few minutes: everything you believe about your customer inside the building is a guess until you go talk to a real person. It is the cleanest starting point for why a live conversation beats sitting with survey numbers when you are still figuring out the problem. Treat it as the framing, not the full method.

Steve Blank: Want Your Startup to Succeed? Get Out of the Building

On Inc. Magazine (YouTube) by Steve Blank (Inc. Magazine) About 3 minutes

Any assumption you have about who your customer is and what they need is a guess until you test it with a real person face to face.
A conversation lets you follow up, watch reactions, and hear the problem in the customer's own words, which a fixed survey form cannot do.
Early stage is about discovering the problem, so you want depth and surprises, not clean averages yet.

Why we picked it This piece sorts research methods along attitudinal versus behavioral and qualitative versus quantitative, so you can see exactly where interviews and surveys each sit. The line that matters for you: qualitative methods (interviews) answer why and how to fix, while quantitative methods (surveys) answer how many and how much. That framing tells you a survey is not good enough at the start because the start is a why question.

When to Use Which User-Experience Research Methods

From Nielsen Norman Group by Christian Rohrer About 12 minute read

Interviews are qualitative and attitudinal, best for understanding why people behave a certain way and uncovering problems you did not know to ask about.
Surveys are quantitative and attitudinal, best once you already know the questions and want to measure how common an answer is across many people.
Early on you usually do interviews first to find the real questions, then use surveys later to size and confirm what you learned.
