40 Best Use Case Templates

1. Reuse Consistent Structure
Use a standardized template structure across all use cases to ensure consistency and easier comparison. Include sections for title, actors, description, preconditions, main flow, alternate flows, and postconditions.

2. Clear Actors and Pre/Post Conditions
Define primary and secondary actors explicitly and specify preconditions that must be met before the use case begins, as well as postconditions that reflect the outcome. This clarity helps avoid ambiguity during development and testing.

3. Maintain Traceability and Versioning
Version each template and link use cases to higher-level requirements or user stories. This enables impact analysis when requirements change and keeps the template aligned with project goals.
