One to three concrete research questions are formulated and aligned with stakeholders.
User Interviews
Prerequisite
What needs to be finished first
At least 5 suitable participants from the target group are recruited, with appointment, incentive, and consent.
Preparation
What needs to be ready before start
Interview guide (semi-structured, 6-10 open main questions plus probes); recording tool with consent; notes template or live note-taker; calibration pilot completed.
One interviewer as lead; one note-taker (can be same person if recorded); optional second observer for synthesis; recruiter for scheduling.
Research questions; hypotheses or assumptions to test; participant demographics and background; known sensitive topics.
30-60 min per session, plus 2-4 h synthesis after all sessions
Guide in funnel structure: warm-up, context, main themes, deepening, closing. 5 participants for first saturation threshold, max 12-15 for affordable insight. Written recording consent upfront. Pilot with 1 person to refine guide.
Core question
The one question this method answers
How do users behave in real situations, which motives drive them, and which pain points should shape discovery or design decisions?
Flow
Marker: Phase
| Step | Duration | Action | Hint |
|---|---|---|---|
1Phase 1: Guide pilot | 1-2 h preparation + 1 pilot interview | Check guide against hypotheses. Run pilot interview with 1 target-group person or proxy. Rephrase or remove questions that do not work. | Skipping pilot costs data quality later. At least one practice iteration, otherwise the first real interviews teach the interviewer at the expense of insights. |
2Phase 2: Conduct interviews | 30-60 min per session | Warm-up, context, 4-6 main questions with follow-ups, closing. Open questions, no leading questions. Probe interesting anecdotes. | Leading questions distort. Yes/no questions waste depth. If you already expect an answer, rephrase the question. |
3Phase 3: Condense notes immediately | 15-30 min after each interview | Directly after interview, add impressions, quotes, surprising moments. Create 3-5 key findings per session. | After 24 h much is forgotten. Immediate condensation is mandatory. Recording alone is not enough. |
4Phase 4: Synthesize all sessions | 2-4 h | Affinity mapping: put highlights on stickies, cluster into themes. Write one insight sentence per cluster with quote evidence. Check hypotheses: confirmed, refuted, open. | Without synthesis, interviews remain loose anecdotes. Synthesis is the actual insight work. |
5Phase 5: Share insights and act | 1-2 h | Create insight document or presentation with top-5 themes, each with quote evidence. Inform stakeholders. Define action idea per insight. | Insights without action fade. Named owner and next step per insight, otherwise interviews become research activity. |
Artifact
What comes out at the end
Interview notes set, one file per session with date, participant code, key points, and quotes, plus synthesis document with top themes, insights, quote evidence, hypotheses, and follow-up actions.
Own project folder per research round with date, research question, and sample description. Version insights with validated/refuted status. Explicitly reference previous insights in follow-up research.
- Notion or Confluence with template page per interview
- Dovetail or Condens for structured tagging synthesis
- Miro with affinity mapping board
- Google Docs with table and heatmap
- Aurelius or EnjoyHQ for research repository

Concrete filled scenario, fictional example
Research synthesis - Onboarding for solo tax advisors (CW 18/2026, n=7)
Research question: What drives solo tax advisors to test new accounting software, and which barriers stop the switch?
Top themes
Theme 1: Trigger is always concrete pain, never innovation
- 6/7 switched after data loss, price increase, or critical bug
- Quote (P3): "I only tested DATEV Online after the old software ate my receipts for the whole quarter."
- Implication: focus marketing on trigger moments, not abstract benefits
Theme 2: The 30-minute test decides
- 7/7 test software first, then read docs. If no aha moment after 30 min, they uninstall
- Quote (P1): "If I have not booked my first receipt in half an hour, the app is gone."
- Implication: onboarding must enable first productive receipt within 30 min
Theme 3: DATEV export is sine qua non
- 7/7 named DATEV compatibility as mandatory
- Quote (P5): "Without DATEV export, I do not even need to look at your software."
- Implication: DATEV export as above-the-fold headline, not hidden in feature list
Pitfalls
Recognize symptoms and steer against them
Leading instead of open questions
Questions contain expected answer.
Rephrase into open how/what/when questions. Follow yes/no answers with "Tell me more."
Confirmation bias in synthesis
Insights suspiciously confirm what the team already believed.
Assign a devil's advocate during synthesis who actively searches for refutations. Capture quotes even when uncomfortable.
Wrong target group recruited
Participants come from convenience sample and do not represent target group.
Apply recruiting filters strictly: demographics, behavior, tool stack. Use external recruiters for hard-to-reach groups.
Too many interviews without synthesis
15 interviews conducted, synthesis postponed, notes are forgotten.
Synthesize iteratively every 3-5 interviews. Check saturation and stop when no new themes appear.
Recording instead of notes
Team relies on recording, notes are poor, synthesis becomes hard.
Live notes plus recording. Add highlights directly after interview while impressions are fresh.
