An equivalent Use Case
that describes the same
“Send a picture to other
users” requirement
Observation
is a key
component
in getting
good use cases
written.
A use case’s sequence
normally contains more
steps and detail than a
user story. This makes
it easier to work to
for developers, but
means extra work with
the customer to nail
these details down.
1. Click on the “Send a Picture button”
2. Display users the picture can be sent to in
the address book list box.
2a. Enter the destination user’s name in the
search box
2b. Click on search to find the user
3. Select the user to send the picture to
4. Click on send
Send a picture to other users
5. The receiver is asked if they want to accept
the photo
5a.1. The receiver accepts the photo
5a.2. The receiver views the photo
5b.1. The recevier rejects the photo
5b.2. The photo is trashed.
So what’s the big difference?
Well, actually not a lot, really. User stories are usually around three lines long, and are
accompanied by an estimate and a priority, so the information is all in one bite-sized place.
Use cases are usually reasonably more detailed descriptions of a user’s interaction with the
software. Use cases also aren’t usually written along with a priority or an estimate—those
details are often captured elsewhere, in more detailed design documentation.
User stories are ideally written by the customer, whereas traditionally use cases are not.
Ultimately either approach does the same job, capturing what your customer needs your
software to do. And one use case, with alternate paths (different ways to use the software in
a specific situation) may capture more than one user story.

You can add more
detail to your user
story, or modify your
use case to have a
little less detail... it’s
really up to you and
your customer.
There are a number of
different ways that you can
write down a use case. This
one describes the interactions
that a user has with the
software, step by step.
