The BDD process looks like this:
A SubjectMatterExpert (typically a business user) works with a BusinessAnalyst to identify a business requirement. This is expressed as a story using the following template:
As a Role
I request a Feature
To gain a Benefit
The speaker, who holds the Role, is the person who will gain the Benefit from the requested Feature.
This can also be paraphrased variously as ...
I want to achieve a specific Goal, and as a Role I should be able to accomplish this by performing Functionality.
A Role invokes Feature to cause a Benefit
