A discovery brief is a decision tool, not a long document created for its own sake. It should help everyone explain the same problem and identify what remains uncertain.
Start with the workflow
Describe who is trying to do what, what makes the task difficult today, and why changing it matters. A concrete example is more useful than a broad statement such as “we need digital transformation.” Note the existing tools, manual handoffs and exceptions that people work around.
Define the first useful outcome
Separate the long-term vision from the first release. A useful release completes a real journey for a defined user. It is not simply a collection of screens. Agree acceptance criteria that can be checked through observation, tests or a clearly defined business process.
Make constraints visible
Record budget boundaries, timing dependencies, data sensitivity, required integrations and the people who can approve decisions. Unknowns should remain visible. Do not turn a missing answer into an assumption without naming it.
Close with decisions and questions
Keep a list of agreed choices, unresolved questions and the next person responsible for each answer. Review the brief when evidence changes. Its value comes from reducing ambiguity—not from freezing every requirement before learning begins.
