A fully-dressed use case includes actors, preconditions, triggers, a Main Success Scenario with numbered steps, and alternate or exception flows. This format captures how actors interact with a system to achieve specific goals, providing precise and testable expectations.

The Cockburn style format structures use cases by focusing on primary and supporting actors, goal-oriented verb-led titles, and fully-dressed templates. It enforces rules for main scenario steps, alternates, exceptions, and relationships to capture precise system interactions.

Use fully-dressed use cases for critical flows requiring precise specifications and testable expectations, including preconditions, postconditions, and triggers. Use casual formats for early exploration when you need to quickly draft how actors interact with a system without full structural detail.

Structure preconditions and postconditions within a fully-dressed template alongside the Main Success Scenario. Preconditions define the required state before triggers activate the flow, while postconditions specify the guaranteed system state after the goal is achieved or exceptions occur.

Yes, the approach supports use case elicitation and level classification through a phase-guided process. It covers setup, format selection, level classification, and diagram relationships to ensure the use case accurately describes how actors interact with a system.

Cockburn-style use cases enforce a strict structured template for main scenario steps, alternates, and exceptions, which may introduce overhead for early exploration. Casual formats are recommended initially, reserving fully-dressed templates for critical flows requiring precise specifications.
