Explanation
The user story "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" is not aligned with the existing scope of the project, which is to support external customers and broaden the organization's brand and increase customer engagement. This user story is focused on the internal staff and their convenience, rather than the external customers and their needs. Therefore, the BA must suggest that the story be included with a change to solution scope or be removed, as it may not add value to the project or the stakeholders. The BA should evaluate the alignment of the user stories with the existing scope by using the scope statement, the business case, and the business objectives as the reference points1. The other options are not the best techniques that the BA should use to evaluate the alignment of the user stories with the existing scope, as they may not address the issue of scope creep or misalignment. Adding the functionality to the list of requirements may increase the complexity, cost, and risk of the project, without delivering the expected benefits. Asking the product owner to rank the user story against the existing product backlog may not resolve the conflict or inconsistency between the user story and the scope statement. Reviewing the business objectives and determining the potential value may not be sufficient to justify the inclusion of the user story, as it may still contradict the scope statement or the business case.
