What are the three formats for use cases?
Use Case Formats Use-case model overview: A format for understanding the “big-picture” Use-case brief descriptions: A format for writing summary use cases.

Here’s what I think are some of the key differences: User stories are about needs. Use cases are about the behavior you’ll build into the software to meet those needs. User stories are easy for users to read. Use cases describe a complete interaction between the software and users (and possibly other systems).
