Market Research Template for Product Analytics

Eight to twelve for most product research questions. Academic research suggests that thematic saturation (hearing no new insights) typically occurs between the 8th and 12th interview for a well-defined participant profile. If you are still hearing new themes after 12 interviews, your participant profile is too broad. Narrow the criteria and continue. The [Product Discovery Handbook](/discovery-guide) covers interview technique in depth.

PMs should do their own research for most product decisions. The learning from conducting interviews personally is more valuable than a polished report from a research firm. Hire a firm for large-scale quantitative studies (n>500), pricing research requiring specialized methodology (conjoint analysis), or market sizing that requires industry expertise. For everything else, a PM with this template and 2 weeks can produce actionable findings.

Three channels work well. LinkedIn outreach (2-5% response rate, target specific titles with a personalized message explaining the research purpose and offering a $50-100 incentive). Respondent.io or UserTesting panels (pre-screened participants, $50-150 each, fast turnaround). Industry Slack communities and Reddit (post a screening survey, lower response rate but free). For enterprise research, ask your investors and advisors for warm introductions.

The qualitative data is usually right about the "what" and "why." The quantitative data is right about the "how many." If 9/10 interviews say SSO is critical but only 40% of survey respondents rank it as their top priority, it means SSO is critical for the enterprise segment you interviewed but not for the broader market. Segment your survey data to match your interview profile and the conflict usually resolves. The [glossary definition of product-market fit](/glossary/product-market-fit) covers how to evaluate signal strength across different research methods.

Five interviews and a competitor audit. This can be done in 3-5 days. Interview 5 people from your target segment (30 minutes each), synthesize themes, and audit 3 competitor solutions. This gives you directional insight for a product decision without the overhead of a full research project. It is not statistically rigorous, but for most early-stage product decisions, directional confidence is sufficient. ---
