Choose one meaningful task: a buyer compares services, a customer requests an appointment or a staff member updates a record. Describe who starts it, what they already know, what they need to decide and what should happen at the end. Walk through the current arrangement using representative information. Note the point where a person needs help or cannot proceed.
Do not turn every observation immediately into a new feature. If the offer is unclear, revised content may be the first useful work. If a person cannot find an existing action, structure and interaction design deserve attention. If the desired result cannot be produced by the present system, development or an appropriate connection may be needed. A short investigation can therefore change the commission without pretending that all problems have a design-only solution.
