The lead BA should tell the junior BAs to include who, what, and why in a user story. Who, what, and why are the essential elements of a user story that define who is requesting a feature or functionality (the user or persona), what they want to achieve or accomplish (the goal or value), and why they want it (the reason or benefit). A user story should include who, what, and why because it helps to:

Clarify the scope, functionality, and quality of the user story

Provide a basis for testing and validating the work done

Ensure that it meets the user’s needs and expectations The other options are either incorrect or irrelevant. Option A is incorrect because V2MOM is a structure that defines an organization’s vision, values, methods, obstacles, and measures, not a user story. Option C is incorrect because technical details are not part of a user story, but rather part of acceptance criteria or design specifications.
