In-Depth Interviews

What do the people closest to the decision know that public data cannot show?

An in-depth interview is a one-to-one conversation, usually 30 to 60 minutes, with a buyer, user, distributor or industry expert. It gets past the official story to how decisions are actually made, what is changing and where the opportunities are. Credence Research finds the right people, runs the interviews with trained analysts and pulls the findings together around the client's question.

When in-depth interviews are the right tool

Interviews fit questions that are complex, sensitive or held by a small number of informed people.

Understanding B2B buying

Learn how procurement, technical and finance teams share a decision, and what each of them needs to see.

Checking market assumptions

Test a forecast, price level or adoption timeline with people who work in the market every day.

Exploring a niche or emerging field

Map a market where published data is thin by speaking with its practitioners and early adopters.

Learning from lost or won deals

Hear directly from customers why they chose a supplier, switched or walked away.

Questions in-depth interviews answer

Decision process

  • Who is involved in a purchase, and who has the final say?
  • Which criteria rule a supplier in or out?
  • How long do qualification and approval take?

Market reality

  • Where do current suppliers fall short?
  • What price and contract terms are typical?
  • Which changes in regulation or technology matter most?

Outlook

  • How will buyers' needs change over the next few years?
  • Which new entrants or substitutes are being watched?
  • What would make buyers switch?

Validation

  • Do informed people agree with the client's assumptions?
  • Where do their views differ, and why?
  • Which figures need more evidence?

Choosing the right method

Interviews give depth from a carefully chosen sample. They complement desk research and surveys rather than replacing them.

Illustrative example

This example is illustrative. It shows how a study could be designed and does not describe a client project.

Understanding hospital purchasing of infusion pumps

Illustrative example
Business question
A device company wants to know how hospitals in two European countries choose infusion pumps and what would make them consider a new supplier.
Approach
Interviews with biomedical engineers, nurse managers, procurement officers and tender consultants, recruited through specialist networks and screened for direct involvement in recent purchases.
Outputs
A map of the decision process by hospital type, ranked selection criteria, typical tender terms and the main barriers a new supplier faces.
Decision supported
Which hospital segments to target first and what evidence the sales team must prepare for tenders.

How research quality is protected

Primary research is only as good as the people who answer and the way questions are asked. Each study applies safeguards at every stage, and the report states the limits that remain.

Where a finding rests on a small number of responses or a single source, the report says so plainly.

What this study does not include

Interview programs gather views and experience, within clear boundaries.

  • Requests for confidential competitor information or trade secrets
  • Interviews with people who are not free to take part under their employer's rules
  • Introductions or sales meetings with interviewees

Respondents take part voluntarily, give informed consent and are told how their answers are used. Personal data is handled under applicable data protection law and recognized market research codes of conduct, and individual answers are reported only in aggregate unless a respondent agrees otherwise. Interviewees are not asked to share confidential information about their employer.

What you receive

Outputs are agreed at scoping; this is a typical set.

  • Interview plan

    Target roles, organizations, number of interviews and the discussion guide.

    Use it to confirm coverage before calls begin.

  • Interview notes

    Structured notes for each interview, anonymized where agreed.

    Use it to trace each finding to its source type.

  • Synthesis report

    Themes, points of agreement and disagreement, and implications for the decision.

    Use it to brief leadership with evidence.

  • Assumption check

    A table comparing the client's key assumptions with what interviewees said.

    Use it to adjust plans and models.

  • Debrief call

    A session with the interviewing analysts.

    Use it to ask follow-up questions on the findings.

How an interview program works

  1. 1

    ScopingThe question, roles to reach, geographies and number of interviews are agreed.

  2. 2

    Guide designA semi-structured guide is written so each interview covers the core topics while leaving room to follow new leads.

  3. 3

    RecruitmentInterviewees are identified through industry networks, specialist recruiters and screened outreach, and confirmed against the target profile.

  4. 4

    InterviewsTrained analysts conduct calls by phone or video, or in person where needed, with consent obtained before any recording.

  5. 5

    SynthesisNotes are coded, compared across roles and regions, and turned into findings tied to the decision.

Frequently asked questions

Discuss your interview program

Describe the decision and the people whose views matter most. An analyst will suggest the roles, regions and number of interviews.

What happens next

A Credence Research analyst reviews the brief and makes contact to discuss scope, method and sample. If existing research can answer the question, the analyst points to it.
