Semi-Structured Interview¶
Interview method — instantiates Lived Experience Capture
Runs a one-on-one conversation from a prepared guide of open questions, covering the decision-relevant ground while leaving room to follow the unexpected — with a deliberate choice of whom to talk to.
Semi-Structured Interview is the disciplined middle between a rigid questionnaire and an open conversation. The researcher comes with a guide — a prepared set of open questions that mark the ground the decision needs covered — but is free to reorder, skip, probe, and follow a thread the participant opens that the guide never anticipated. The single idea that makes it this mechanism is that structure and openness are held in deliberate tension: enough structure that every interview reaches the decision-relevant questions and the accounts can be compared, enough openness that unexpected meanings and examples can surface instead of being crowded out by a script. It is the archetype's workhorse for eliciting experience directly and comparably — and it is also where the choice of whom to interview is made, because a comparable set of accounts is only as good as the range of people it was drawn from.
Example¶
A meal-kit subscription is bleeding customers, and the cancellation survey — a drop-down of tidy reasons — says everyone left over "price." To find out what "price" actually stands for, the team runs semi-structured interviews. They first decide the sampling frame: not only churned subscribers but also long-tenured ones and a few who cancelled in the first week, so the range of experience is covered rather than just the loudest complainers. Each interview works from the same short guide — walk me through a typical week with the boxes, tell me about the last one before you cancelled — but follows wherever the person goes. The pattern that emerges is not price at all: subscribers describe the guilt of unopened boxes piling up when a week got busy, and the friction of pausing being buried three menus deep, so "too expensive" was really "I felt wasteful and couldn't easily stop." The guide guaranteed every interview reached the cancellation moment; the openness let the guilt surface; and the sampling frame is why the finding reflects the customer base rather than one vocal segment.
How it works¶
The distinguishing machinery is a guided-but-flexible one-on-one conversation over a purposively chosen set of people. The interview guide fixes the topics and the open, non-leading phrasing so that coverage is consistent and accounts are comparable, while the interviewer's latitude to probe ("say more about that," "what happened next") turns a stated answer into a lived example. Around the conversation sits the designed elicitation setting — building enough rapport that people speak candidly, managing the power difference between institution and participant, and honoring consent — and behind it sits a deliberate sampling frame: which experience holders to recruit, including the abandoned and the excluded, and how many before the accounts stop yielding anything new.
Tuning parameters¶
- Guide rigidity — a tight question list versus a loose topic checklist. More rigidity improves comparability across interviews; more looseness catches the unanticipated but makes accounts harder to align.
- Probing depth — how far the interviewer chases each thread. Deeper probing surfaces reasons and examples; over-probing tires the participant and can lead the witness.
- Rapport investment — how much time goes to putting the participant at ease before substance. More rapport unlocks candor on sensitive ground; less keeps the session short but shallow.
- Sampling range — how wide a spread of experience holders is recruited, including hard-to-reach and excluded ones. A wider frame guards against a convenience sample; it costs recruiting effort and access.
- Sample size / stopping rule — how many interviews before stopping. More interviews approach saturation and coverage; each adds cost and analysis load.
When it helps, and when it misleads¶
Its strength is flexible, comparable elicitation: the guide guarantees the decision-relevant ground is covered in every conversation, while the freedom to follow a thread lets meanings the researchers never thought to ask about emerge — and the whole thing is fast and adaptable enough to be the default first instrument. Its characteristic failure is that a poorly drawn sampling frame quietly decides the result: interview only the reachable and the willing and you get a convenient, unrepresentative picture that looks authoritative. Related failures are leading questions that plant the answer, and stopping too early — before the accounts have saturated[n1] — so a real pattern is missed. The disciplines that guard against these are drawing the frame to cover the range (especially the people who abandoned or were excluded), keeping questions open and non-leading, and interviewing until new accounts stop adding anything rather than to a fixed convenient number.
How it implements the components¶
elicitation_context— its signature: the interview guide, the rapport, the management of power and consent together form the designed setting in which people are drawn out to speak candidly about their experience.experience_scope— the guide scopes each conversation to the decision-relevant situation (the cancellation, the touchpoint, the role), keeping the elicitation actionable rather than a boundless chat.experience_holder_sampling_frame— it is the mechanism where whom-to-talk-to is decided: the purposive recruitment of a range of holders, including the abandoned and excluded, and the stopping rule for how many.
It does not preserve the participant's account as a whole, self-sequenced story — that narrative fidelity is Narrative Account Collection's first_person_account, whereas an interview deliberately breaks experience into answers to the guide's questions — and it does not read meaning from immersion in the setting the way Ethnographic Observation does with contextual_meaning_trace.

Editorial Notes¶
Form Classification¶
Form family: Communication, Facilitation & Learning
Rationale: Semi-Structured Interview operates as a designed message, facilitated interaction, ritual, or learning activity that changes shared understanding because it runs a one-on-one conversation from a prepared guide of open questions, covering the decision-relevant ground while leaving room to follow the unexpected — with a deliberate choice of whom to talk to.
Independent corroboration: The frozen evidence defines Semi-Structured Interview as 'Runs a one-on-one conversation from a prepared guide of open questions, covering the decision-relevant ground while leaving room to follow the unexpected — with a deliberate choice of whom to talk to', so its operative form is Communication, Facilitation & Learning.
Review outcome: Independent reviewer agreement; high confidence.
Origin Attribution¶
Primary origin: Ethnography & Qualitative Methods
Origin pattern: Convergent development
Present-day reach: Universal
Rationale: A prepared guide of open questions combined with responsive probing is a standard qualitative-research interviewing method.
Related originating lineages:
- Communication & Media Studies — Reported interviews also balance prepared topics with follow-up, though evidence and sampling norms differ.
- Medicine & Healthcare — Clinical history-taking and qualitative health research widely use semi-structured protocols.
- Psychology — Clinical and research interviewing uses guided flexibility to elicit comparable yet individual accounts.
- Sociology & Anthropology — Interview studies developed sampling, rapport, probing, and thematic-analysis conventions.
Review resolution: The blind reviewers agree that ethnography_qualitative_methods is the primary origin and differ only on alternate origin disagreement, origin mode disagreement, domain reach disagreement. I preserve every independently explained alternate from both records rather than imposing a numeric cap. I retain convergent because the combined record shows independent disciplinary development. The broader reach of universal records portability separately from historical provenance, and encyclopedia_synthesis=false preserves the affirmative synthesis judgment where either reviewer identified one.
Review outcome: Reconciled after independent review; high confidence.
Notes¶
Semi-Structured Interview and Narrative Account Collection are the archetype's two talk-based instruments, and the distinction between them is which party holds the structure. The interview runs on the researcher's guide — the questions define what gets covered, and comparability across people is the prize — so it is the better choice when specific decision-relevant ground must be reached in every conversation and the accounts need to line up. Narrative collection cedes the structure to the teller. When you need coverage and comparison, interview; when you need the person's own framing preserved intact, collect the narrative.
[n1] Saturation (from grounded theory, Glaser & Strauss) is the point at which additional interviews stop yielding new themes or categories; it is the principled stopping rule that replaces "however many we could get," and reaching it is what lets a small qualitative sample claim it has covered the range rather than merely sampled the convenient. ↩
