Reader intent

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.

  • Launch owners working back from a date

    Where in-depth interviews realistically fits between sign-off and the decision it has to inform.

  • Project managers sequencing workstreams

    Which stages can run in parallel, and which genuinely cannot.

  • Agencies setting expectations

    Realistic timings to quote, and the three things that most often cause slippage.

01

Stage by stage

  • Briefing and proposal: 1–3 days
  • Design and translation: 3–7 days
  • Pilot: 1–2 days
  • Fieldwork: 1–3 weeks
  • Analysis: 4–7 days
  • Reporting and debrief: 3–5 days

02

How to move faster

Approve materials quickly, keep the questionnaire short, and accept topline results ahead of the full report.

What goes wrong

Common mistakes in in-depth interviews

Most disappointing in-depth interviews 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

    Questions that carry their own answer

    “What do you dislike about the service?” presumes dislike. Ask what happened last time, then follow the story rather than the hypothesis.

  • 02

    Accepting the first answer

    The first response is a rationalisation. Laddering — asking why that matters, three or four times — is what separates a depth interview from a long survey.

  • 03

    Recruiting everyone from one source

    Twenty-five interviews all sourced from a single customer list describe that list, not the market. Use at least two independent recruitment routes.

  • 04

    Counting mentions as if they were data

    “14 of 25 said” lends a qualitative sample the authority of a survey it has not earned. Report themes and their reasoning, and quantify separately if you need numbers.

  • 05

    Regional language nuance lost in translation

    Category language in Hindi, Tamil or Marathi rarely survives live translation. Work in the respondent's language and translate the transcript, not the conversation.

  • 06

    Verbatims presented as findings

    A deck of quotes is evidence, not a conclusion. Code to themes, note how widely each appears, and write the implication for the decision beside it.

Run through this before sign-off

Your checklist before you brief anyone

A working sequence for a in-depth interviews project. Most of it costs nothing, and it saves the two weeks a re-field would take.

  1. 1

    Write the screener before the discussion guide; who you talk to decides more than what you ask.

  2. 2

    Pilot two interviews and rewrite the guide before the rest are scheduled.

  3. 3

    Record and transcribe with explicit consent, and keep the recording in the interview language.

  4. 4

    Ladder every important answer with “and why does that matter to you?” at least twice.

  5. 5

    Code to a shared framework, so two analysts reading one transcript reach the same themes.

  6. 6

    Record and transcribe in the respondent's own language, with consent captured in writing.

  7. 7

    Agree in writing who acts on each finding, and by when, before the debrief ends.
