User story formats

 

Now, usually the user stories that we write are of the format :
As A Bank Teller, I Want a name search field, So That I can quickly look up customers.

But like someone pointed out, it makes much more sense to construct the story as follows:
So That I can quickly look up customers, As A Bank Teller, I Want a name search field.

Further more, now we can relate the So That to actual business values and we also got rid of explicit implementation details from I Want, as follows:
So That I can serve customers faster, As A Bank Teller, I Want an efficient way to look up customers.
