So if a user story is a something nebulous like:
As a sales rep, I would like to capture the contact information so that I can follow up later on.
I'm not even sure if that's a valid user story but I'm sure it's close enough.
Then there are details/tasks for implementing that user story. And I'm sure "The sales rep should be able to tab from one textbox to another." is one of the requirements. How do we capture/track this? Is this part of the user story or is it something that's to be considered separately?
