How deep are the requirements? Do you describe the business logic in detail with steps or only use diagrams?

Requirements are usually described with varying levels of detail depending on the project and audience. Ideally, business logic should be described in detail, with a step-by-step breakdown of key processes, so that all participants understand the sequence of actions and transition conditions. This helps avoid ambiguities and errors during implementation.

However, diagrams (such as BPMN, state diagrams, or flowcharts) are often used to visually reflect the logic and simplify understanding. A good practice is to combine both approaches: diagrams for general understanding and textual descriptions for details, exceptions, and business rules.
