Exam CCBA topic 1 question 509 discussion

An organization's board of directors has funded a new mobile application to support external customers. The business case was developed with emphasis on objectives to broaden the organization's brand and increase customer engagement. The business analyst (BA) is reviewing a group of user stories with the product owner. One of these user stories is: "As a customer service representative, I need to enter my time on the mobile application so that I can leave work to pick up my sick daughter from school". The product owner wants to take advantage of this opportunity to provide the staff a way to enter their time away from the office and create an interface to the Payroll application. How must the BA evaluate alignment with the existing scope?
