Difference between Use Case and User Stories? -

-

this confuses me difference between user stories , use case. user stories description of how system shall behave in different conditions?

the term use case has formal definition in uml:

use cases means specifying required usages of system. typically, used capture requirements of system, is, system supposed do.[...]

i.e., have formal structure , other concepts associated use case (actors, example).

user stories i've seen used informal way describe specific scenario (typically ui scenario) it's not formally described in uml spec.

see uml superstructure spec (check proper link) in chapter 16 more details.

hope helps, best regards.
