Use caseQualitative research
A qualitative research platform that runs your design through one guide in every interview, at the sample your question calls for, and hands your team a first synthesis framed as a draft to challenge.
Qualitative rigor starts before the first interview, in the question, the sampling logic and the guide, and fieldwork either honors those choices or quietly erodes them.
Your brief becomes the interview. Every participant hears the same well-formed questions, follow-ups build on what each person said earlier, and a vague answer gets a second question, so differences in the data come from people.
Participants join the interview when it suits them, from whatever device is to hand, which opens the study to shift workers, parents and people in other time zones who rarely fit a moderator's session grid.
Decide the sample from the research question and the variation you need to capture, such as enough participants in each subgroup to compare them, and plan the analysis around that logic before fieldwork begins.
The world's most ambitious teams research with Pulse.
GrowwJudgment about meaning, method and sufficiency stays with the research team, and each output arrives in a form that invites their scrutiny.
Pulse's first grouping of themes, each with the quotes behind it, goes to the team as a draft, so the team argues with it, notes its open questions, reworks it and signs only the version it stands behind.
The researcher decides from the question which method fits. For the interviews, Pulse builds an AI-moderated interview from the brief, which the team reviews and edits before anyone is recruited, and a survey can run alongside when the question is how many.
Fieldwork closes when new interviews stop adding themes in each subgroup, a stopping point the team reads from the data as it comes in and records in the method section of the report.
In-depth interviews, focus groups, ethnography and diary studies are the main tools of qualitative work, which explores experiences, motivations and meaning. Its strength is explanation, showing why people act as they do and surfacing issues no survey question anticipated. Rigor comes from design choices made up front, including purposive sampling, a consistent and neutral guide and systematic analysis, and from being open about how findings were reached. Thematic analysis, the most common approach, codes transcripts and groups the codes into themes that are checked back against the data. Sample size follows the question and the comparisons it requires, and many teams stop adding interviews once each one brings no further themes, a point called saturation, which is one stopping rule among several. The in-depth interview is the method most studies rest on, a one-to-one conversation that follows a guide while leaving room to probe, and it runs long enough for a participant to move from general opinion to specific experience.
Qualitative findings are the easiest to dismiss as anecdote. A skeptical reviewer can follow any theme to the transcripts and recordings behind it, the audit trail qualitative rigor asks for, and judge the interpretation against the data.
Purposive sampling means choosing people for the characteristic the question turns on: a condition, a role, a way of working. The screener selects on it and recruitment follows, with fraud checks, so the sample stays purposive at thirty participants as at eight.
A qualitative design is easiest to replicate when it is written down. The brief holds the question, the topics, the participants and the screening rules, so a colleague in another unit can adapt the design to their own population.
