“If you approach a new piece of web
content with ‘how shall I write this?’, that’s
writing or editorial.  
If you approach it from ‘how am I going to
get this across to the audience in the best
way possible?’, that’s content design.”

Sarah Richards  
Author of Content Design

What’s a User Story?
“A user story is a way of pinning down what
the team needs to do… without telling them
how to do it.”
Sarah Richards | Content Design
25

User Story:
“As a _________________, 
I want to _________________,
So that I can _________________.”
26

User Story:
“As a product user, 
I want to know whether I can replace the handle,
So that I can avoid having to buy a new product
when the handle breaks.”
