I can find my grades online 
so that I don’t have to wait until 
the next day to know whether I 
passed 
As a <role>, 
I want <goal>,

It is a reminder to have a 
conversation with your customer - 
not a complete specification
User Story conversation 
Start with a short title 
Add concise description 
As a [role] 
I want to [do something 
So that I can [reach a goal] 
… 
Create an acceptance criteria 
Add anything else relevant from conversation 
(notes, specifications, constraints, sketches)

“incrementing” builds a bit at a time 
Incrementing calls for 
a fully formed idea. 
And, doing it on time 
requires dead accurate 
estimation.

“iterating” builds a rough version, 
validates it, then slowly builds up quality 
Iterating allows you
