Which mistake did the BA make when creating this story?

A business analyst (BA) at Northern Trail Outfitters was asked to create a new user story for a Sales Cloud update requested by the inside sales team.

The BA created the following story: "As a user, I need visibility to customers’ purchase history details so I can increase efficiencies and improve closure rates by better tailoring sales offerings."

Which mistake did the BA make when creating this story?
A . The goal is undefined.
B . The persona is undefined.
C . The need is undefined.

Answer: B

Explanation:

The mistake that the business analyst made when creating this story is that the persona is undefined.

A persona is a fictional representation of an end user who has a specific role, goal, or need. A user story should specify the persona as part of its format: “As a [persona], I need [need], so I can [goal]”.

Specifying the persona can help the business analyst communicate who will use the feature and why it matters to them. The goal and the need are defined in this user story. The goal is to increase efficiencies and improve closure rates by better tailoring sales offerings. The need is visibility to customers’ purchase history details.
