Interviewing Users

People are unreliable about the future and reliable about the past. Every technique here is a way of trading a prediction for a memory.

Ask about the last time, not about the general case

The pattern: swap the hypothetical for a specific past episode, then follow the detail. A problem someone has never worked around is a problem they do not have.

Structure of an interview

Sixty minutes, roughly:

  1. Two minutes of context. What this is for, that there are no wrong

answers, and permission to record.

  1. Five minutes on their role. What they actually do in a week, not their

title.

  1. Thirty-five minutes on the episode. One recent instance of the problem,

in sequence: what triggered it, what they tried, what it cost, what happened in the end.

  1. Ten minutes on the workaround. What they use now, what they pay, what

they have already tried and dropped.

  1. Five minutes to close. Anything expected but not asked, and who else

should be spoken to.

Notice the shape: no part of that is about the product. If it comes up, it comes up at the end, after the evidence is collected.

data.

Recruiting

Talk to people who have the problem now, not people who resemble the target segment. Five interviews with people who did the thing last month beat twenty with people who might one day. Screen with a behaviour question — "when did you last do X" — not a demographic one.

Turning transcripts into evidence

After each interview, before the next one, write:

Then, across interviews, count. "Four of six had already built a spreadsheet to do this" is a finding. "Users want better reporting" is a summary of nothing.

Keep the disconfirming cases. The interview that contradicts the emerging story is the most valuable one, and it is the one most likely to be quietly dropped.

What a good finding looks like

Claim      Ops leads reconcile invoices by hand at month end.
Evidence   5 of 7 described doing this; 3 showed the spreadsheet.
Cost       2-6 hours per month end, self-reported, twice observed live.
Workaround Two had built macros; one pays an assistant for the day.
Confidence Medium-high — one segment, all under 200 staff.

State the confidence and the boundary. Research that does not say what it does not cover gets applied to everything.
