A useful research brief does not need to have every answer. It needs to make the decision clear. Before you choose a method, recruit an audience or agree a timeline, give your research partner enough context to understand what your team is trying to change.
Start with the decision, not the survey
Are you deciding whether to enter a market, refining a proposition or investigating why customers leave? Those are different decisions, even when they concern the same audience. Describe the choice your team faces, who will make it and what happens next. A clear decision helps distinguish essential questions from interesting but less useful ones.
Share what you already know
Existing studies, sales patterns, customer feedback and stakeholder hypotheses are useful starting points. Explain which findings you trust and which assumptions need testing. Sharing the gaps is just as important as sharing the evidence: it helps avoid repeating work and reveals where a new study can add value.
Describe the people behind the question
A broad label such as ‘business leaders’ rarely tells a recruiter enough. Think about role, recent experience, purchase involvement, category usage and geography. For consumer research, distinguish buyers from users. For expert interviews, identify the responsibilities that make someone relevant, rather than relying only on a senior job title.
Make practical constraints explicit
Share the markets, languages, budget range and decision date that matter. Explain any audiences you cannot contact or topics that require particular care. These details let your research partner discuss feasibility early and propose an approach that fits the assignment, rather than discovering limitations after recruitment begins.
Agree what a useful answer looks like
A strategy workshop, a clean dataset and a customer journey map serve different purposes. Discuss who will use the findings and how they prefer to work. Agree the deliverables, review points and limitations together. The best final brief connects the business question, the evidence needed and the action the team wants to take.
