Study first
Review the ideas behind the questions
Check the research decision before choosing a method. A useful plan says what the team needs to learn, which method can answer it, and what claim the evidence can safely support.
Start With The Decision
Research method choice should begin with the decision the team must make. Objectives, assumptions, and user groups give the method a clear job.
- A round of research should have clear, actionable objectives before methods are chosen.
- Research questions should turn assumptions and opinions into things the team can test.
- Each planned round should answer specific research questions with specific user groups.
In Practice
Name The Action
A good research objective says what decision the team needs to make next, not only what topic sounds interesting.
Do Not Research Every Question
If the team cannot act on the answer soon, keep it out of the next round or lower its priority.
Common mistakes
Picking a familiar method before agreeing what decision the research must support.
Agree the decision, assumptions, and research questions first, then choose the method that can answer them.
Q&A
What should be clear before choosing a research method?
The team should know the decision, the assumptions to test, the user group, and the question the evidence must answer.
When should a research question be deprioritized?
Deprioritize it when the team cannot use the answer in the near-term roadmap or decision cycle.
Choose Evidence That Fits
Different methods answer different kinds of questions. The safest choice keeps the research claim within the method's actual strength.
- Qualitative methods are stronger for why and how-to-fix questions; quantitative methods are stronger for how-many and how-much questions.
- Attitudinal research shows what people say or believe; behavioral research studies what people do.
- Generative, formative, and summative research fit different points in product or campaign development.
In Practice
Size And Cause Are Different Questions
A survey can help size a known issue, but interviews, field research, or usability sessions are often needed to understand why the issue happens.
Context Changes The Evidence
When natural behavior matters, a method that observes customers in their own environment may answer a different question than a scripted lab task.
Common mistakes
Using one method to make every kind of research claim.
Separate whether the team needs cause, scale, behavior, opinion, design improvement, or performance measurement.
Q&A
What should a marketer check before trusting a percentage from research?
Check whether the method, sample, and measurement were designed to answer a how-many or how-much question.
What should a marketer check before trusting a quote?
Check the context, participant fit, and whether the quote explains a behavior or only states an opinion.
Plan Rounds The Team Can Use
A research plan should respect timing, participant count, inclusion, and analysis time. More research is not better if the team cannot use it well.
- For interviews, contextual research, experience mapping, or usability testing, a round usually needs 4 to 8 participants.
- Surveys, A/B testing, and benchmarking need hundreds of participants when the goal is clear findings.
- Research findings should feed into the team's planning and prioritization practices.
In Practice
Use Rounds, Not One Huge Session Plan
When qualitative evidence needs to become clearer, another round can be more useful than one oversized round that cannot adapt.
Include The Users Who May Struggle
If a broad customer group includes people with access needs or low confidence, plan for them rather than treating them as an edge case.
Common mistakes
Planning research that is larger than the team can analyze or act on.
Plan the smallest credible rounds that answer priority questions and leave time for analysis and decision handoff.
Q&A
Why might another small round beat one large qualitative round?
Another round lets the team adjust the question, participant mix, or prototype after learning from earlier sessions.
What makes research easier for stakeholders to use?
The plan should say which decisions the findings will inform and how those findings enter planning or prioritization.
