User Story - User Stories and Use Cases

User Stories and Use Cases

While both user stories and use cases serve the purpose to capture specific user requirements in terms of interactions between the user and the system, there are major differences between them.

User Stories	Use Cases
Provide a small-scale and easy-to-use presentation of information. Are generally formulated in the everyday language of the user and contain little detail, thus remaining open to interpretation. They should help the reader understand what the software should accomplish. Must be accompanied by Acceptance Testing procedures (acceptance criteria) for clarification of behavior where stories appear ambiguous.	Describe a process and its steps in detail, and may be worded in terms of a formal model. A use case is intended to provide sufficient detail for it to be understood on its own. A use case has been described as “a generalized description of a set of interactions between the system and one or more actors, where an actor is either a user or another system”. May be delivered in a stand-alone document.

Famous quotes containing the words user, stories and/or cases:

“A worker may be the hammer’s master, but the hammer still prevails. A tool knows exactly how it is meant to be handled, while the user of the tool can only have an approximate idea.”
—Milan Kundera (b. 1929)

“Every one of my friends had a bad day somewhere in her history she wished she could forget but couldn’t. A very bad mother day changes you forever. Those were the hardest stories to tell. . . . “I could still see the red imprint of his little bum when I changed his diaper that night. I stared at my hand, as if they were alien parts of myself . . . as if they had betrayed me. From that day on, I never hit him again.””
—Mary Kay Blakely (20th century)

“Colonel, never go out to meet trouble. If you will just sit still, nine cases out of ten someone will intercept it before it reaches you.”
—Calvin Coolidge (1872–1933)
