A structured method for describing functional requirements from the user perspective. Captures actors, goals and interaction steps in concrete scenarios to support analysis, prioritization and testable derivation.
Use Case Modeling is a structured method for identifying and modeling functional requirements from the user's perspective. It captures actors, goals and stepwise interactions in concrete scenarios and links business expectations to technical tests. The approach supports shared understanding, prioritization and derivation of implementation tasks.
Share of identified user needs covered by use cases.
Number of clearly formulated, verifiable acceptance criteria per use case.
Average time between drafting a use case and stakeholder validation.
Use cases describe the sequence from cart to payment including exceptions like payment failures.
Scenarios model ticket creation, prioritization and escalation paths.
Use cases define permissions, confirmation mechanisms and error handling for transfers.
Preparation: identify stakeholders and clarify goals.
Elicitation: run workshops, capture actors and primary scenarios.
Modeling: document primary and alternative paths.
Validation: review and adapt use cases with stakeholders.
Derivation: derive acceptance criteria, tests and implementation bundles.
