Say you work on the research team at a rail company. Several teams want something from a study of the new mobile ticket. Marketing wants to know who to target, and finance wants to know if paper tickets can go. So what does the brief need to say before anyone is interviewed?

That document is the market research brief, the plan everyone agrees before a study starts.

A good brief names the decision first. Then it lists the questions in order, each with one owner, says who to talk to and states what result would change the plan.

So how do you get several teams to agree on one page? Start with the decision, then make each question earn its place.

## The short version

- Start the brief with the decision the study will inform, then the topic.
- Write down what the company already knows before asking anything new.
- Give every question one owner, and move the rest to a "later" list.
- Agree what result would change the plan before the study starts.
- Send the brief to everyone at once, with one date to sign by.

## A brief starts from the decision, not the topic

If the brief says "learn about the mobile ticket", that's a topic, and every team reads its own question into it. Marketing hears targeting, and finance hears paper tickets. So the first line of the brief should name the decision the study will inform, because that one line tells you who to talk to and which questions matter.

Compare two first lines. "Understand attitudes to mobile tickets" could lead anywhere. "Decide whether to stop selling paper tickets on commuter routes next year" tells you to talk to commuters who still buy paper, and to ask what they'd do without it.

If you can't name the decision, you're not ready to write the brief.

Then write down, before the study starts, what result would change the plan. Say regular commuters tell you they'd stop taking the train without a paper option. If they do, paper stays on those routes. Agreeing this early stops anyone from reading the results to fit what they already wanted.

## What a market research brief must say

Once the decision is clear, the rest of the brief answers the questions the researcher will ask anyway. Each part has one job, and each has one person who should answer it. The researcher can't guess finance's budget or the legal team's rules, so the brief names who fills in what.

The rail study shows what each part says and who fills it in:

| Part                  | What it says                                           | Rail company example                                              | Who answers it                               |
| --------------------- | ------------------------------------------------------ | ----------------------------------------------------------------- | -------------------------------------------- |
| The decision          | What the company will decide with the results          | Whether to stop selling paper tickets on commuter routes          | The person who owns the decision             |
| Background            | Why the study is happening now                         | The mobile ticket is live; the machine contract is up for renewal | The person who asked first                   |
| What we already know  | Earlier studies and data, with links                   | Last year's interviews about the ticket screen                    | The research team                            |
| The questions         | What the study must answer, most important first       | Who would stop traveling without paper? Where does buying fail?   | Each question's owner                        |
| Who to talk to        | The people to include and how to screen them           | Regular commuters, including some who still buy paper             | The research lead                            |
| Method                | Interviews, a survey or both, or "researcher proposes" | Researcher proposes                                               | The research lead                            |
| Markets and languages | Where the study runs, in which languages               | Both regions the company serves                                   | The team in each region                      |
| Timeline and budget   | When results are needed and what the study can cost    | Results before the machine contract is renewed                    | Finance and the person who owns the decision |
| What done looks like  | The report, and the result that would change the plan  | A short report; paper stays if commuters would stop traveling     | The person who owns the decision             |

Two terms in the table may be new. A screener is the short set of questions that decides who takes part. A [research method](https://pulsecorp.co/glossary/research-method/) is the way you gather answers, such as interviews or a survey.

The brief can suggest a method, or say "researcher proposes" and let the person running the study choose. Either way, say which.

## Cut the questions before the study starts

Between them, the teams send twenty questions. A study that tries to answer all of them answers none of them well, because each interview has only so much time. Two habits shrink the list: check what the company already knows, then give every remaining question one owner.

### Write down what you already know

Marketing thinks nobody has studied mobile tickets. But the app team ran interviews about the ticket screen last year. So before you write new questions, search past studies and add a "what we already know" section to the brief, with links.

Past studies usually live in a [research repository](https://pulsecorp.co/glossary/research-repository/), the shared place a company keeps what it learned from customers. Any question the repository already answers comes out of the brief, so the study spends its time on what's new.

### Give every question one owner

List every question and name one owner for each. Then ask each owner which decision their question informs. Questions tied to the brief's decision stay. The rest go on a "later" list inside the brief, so nobody feels ignored.

The "later" list is what stops the study from growing.

Put the must-answer questions first, because they'll get the most interview time. When the list is settled, you can [turn the questions into an interview guide](https://pulsecorp.co/blog/how-to-write-a-user-research-interview-guide-step-by-step-examples/).

## Who signs off, and on what

The study is ready to start, and the legal team asks how interviews will be recorded and what personal data is kept. If that question arrives now, the start date slips. So agree up front who signs which part, and collect every signature in one round.

In the rail study, the signatures split like this:

- The person who owns the decision signs the decision and what done looks like.
- The research lead signs the method, the people to talk to and the screener.
- The legal or privacy team signs consent, recording and how personal data is kept.
- Finance signs the budget.

Send the whole brief to everyone at once, with one date to reply by. Then a late change from one team doesn't restart the study for everyone else.

If an outside agency will run the study, ask whether it works to ISO 20252\. The [Market Research Society describes ISO 20252](https://www.mrs.org.uk/standards/quality-standards#:~:text=ISO%2020252%20establishes%20the,insights%20and%20data%20analytics.) as the standard that sets terms, definitions and service requirements for companies that run market, opinion and social research.

Start the study only when every part has a signature. If the decision line is missing, stop there, because every other part depends on it. Once the brief is signed, you can [turn the brief into a research plan](https://pulsecorp.co/blog/user-research-plan-how-to-create-one-template-example/).

## Where Pulse fits

In the rail study, the brief everyone signed should be what every participant is asked about. In Pulse, you set the research question, the areas to cover, the audience and the screener, and [Pulse builds the interview from that brief](https://pulsecorp.co/product/ai-interviews/#:~:text=Set%20the%20question%2C%20the%20areas%20to%20cover%2C%20the%20audience%20and%20the%20screener.). You can review and edit the questions before the study starts.

If the study covers both regions, [one study can run across several markets at once](https://pulsecorp.co/product/multi-market/#:~:text=In%20Pulse%2C%20one%20study,belong%20to%20one%20market.), from one brief and discussion guide. And the [insight repository](https://pulsecorp.co/product/insight-repository/#:~:text=In%20Pulse%2C%20every%20study%27s,before%20running%20something%20new.) keeps every study's themes, quotes and transcripts together beside earlier studies, so your "what we already know" section can start there.

Pulse runs the interviews and the first synthesis, so your team's time goes to framing the decision and getting it signed. To see a brief turn into a running study, [book a demo](https://pulsecorp.co/demo/).

## Questions readers ask

### 1\. Is a research brief a plan or a summary of findings?

Both meanings are in use. In market research, a brief is the plan written before a study, telling the researcher what decision it serves and who to talk to. In universities and policy work, a research brief is often a short summary of findings written for busy readers after a study.

### 2\. Who should write the research brief?

The research lead usually writes it, because they know what a study can and can't answer. But the person who owns the decision should write the first line, the decision itself, and the last, the result that would change the plan. Each question's owner writes their own question.

### 3\. What is the difference between a research brief and a research proposal?

The brief comes from the company and says what it needs to know and why. The proposal is the researcher's reply. It says how they'll run the study, covering the method, the people, the timing and the cost. A clear brief makes proposals from different agencies easy to compare.

### 4\. How long should a market research brief be?

Long enough to cover every part in the table, and short enough that each team reads all of it. If it runs past a few pages, the study is probably trying to answer too many questions. Some of them belong on the "later" list.
