Write the smallest useful brief.

Begin with someone.

A project title can describe a subject without explaining who the work helps. “A reading note” tells us the form. “A reading note for someone who has not opened the original” gives us a reader and a starting situation. That second sentence makes the next choice easier.

Choose one intended reader or participant for the first version. They do not need to represent everyone who might eventually use the work. Describe what they already know, what they are trying to do and the setting in which they will encounter the result. Keep unnecessary personal details out of the brief.

Name the useful difference.

A list of features can grow indefinitely. A useful difference gives the project a purpose: after reading the note, someone can explain one idea; after seeing the map, someone can find the first meeting point; after receiving the invitation, someone knows what the gathering involves.

Use a sentence that describes an action or understanding. “They like it” is hard to observe and often invites a polite answer. “They can describe the promise without a hint” is a narrower question with a visible result. A brief is easier to revise when the intended difference is explicit.

Choose a finishable container.

The first artifact should expose the important question without building the whole future project. A rough paragraph, an actual-size sketch or a paper screen can be sufficient. The container is a limit on this session, not a declaration that the finished project must always be small.

Pick a timebox and one constraint. A one-hour session can produce a rough version and a short review. A week-long session can include revision and a small check. If the plan needs several weeks before anyone can see its central idea, look for a smaller artifact that reveals that idea sooner.

• One reader or participant group.
• One useful difference.
• One visible first artifact.
• One boundary that helps you stop.

Leave the brief open to learning.

A brief is a working agreement with yourself, not a forecast. The workroom offers planning prompts based on your chosen kind of work, timebox and unclear part. It does not know the quality of the result or whether someone will respond as you hope.

At the end of a session, keep one observation and one next move. Change the audience, shape or scope when the evidence gives you a reason. Download the note before leaving; save a browser-local draft only if that is appropriate on the device you are using.
