Explanation
The analysis that a BA should perform is strategy analysis. Strategy analysis is a technique that helps to understand the business context and environment of an organization, its vision and goals, its strengths and weaknesses, its opportunities and threats, its capabilities and resources, and its stakeholders and competitors.
Strategy analysis helps to identify the business problems or needs that need to be addressed, evaluate potential solutions or options that can address them, and align them with the business strategy and objectives. In this case, CK faces challenges with accurate reporting and metrics to use when scheduling service agent shifts. A BA should perform strategy analysis to understand CK's business context and environment, identify the root causes of the challenges, evaluate potential solutions or options that can solve them in Salesforce, and align them with CK's business strategy and objectives.

Explanation
The benefit of using a Center of Excellence (CoE) to define the long-term vision for its Salesforce org is that CK will be better able to prioritize across teams and streamline processes. A CoE is a group of people who provide leadership, guidance, and best practices for a specific area of focus or expertise. A CoE can help CK establish a long-term vision and strategy for its Salesforce org by aligning its goals and objectives with its business needs and capabilities, prioritizing its initiatives and projects across different teams or departments, streamlining its processes and workflows to optimize efficiency and effectiveness, and ensuring quality and consistency in its Salesforce implementation.Getting insights to current business processes may be an outcome of using a CoE, but not a benefit of defining the long-term vision for its Salesforce org. Developing a process to gather feedback from end users regularly may be an outcome of using a CoE, but not a benefit of defining the long-term vision for its Salesforce org. References:

Explanation
A functional requirement specification is a statement that describes what a product or service must do or provide to meet user needs or business objectives. It should be clear, concise, testable, and measurable. The option B is an example of a functional requirement specification because it describes what the portal should do (allow for partners to upload monthly sales reports) without specifying how it should do it or why it should do it.

Explanation
The business analyst should review and revise the acceptance criteria of the user story to provide more clarity to the QA team. Acceptance criteria are specific conditions or requirements that must be met for a user story to be considered done or acceptable. Acceptance criteria should be clear, concise, testable, and measurable.
Reviewing and revising the acceptance criteria of the user story can provide more clarity to the QA team by specifying what functionality or feature must be delivered, how it must be delivered, and who must be able to use it. Reviewing and revising the acceptance criteria of the user story can also help avoid ambiguity, confusion, or misunderstanding between the business analyst and the QA team. The who, what, and why of the user story are not components that the business analyst should review and revise to provide more clarity to the QA team. The who, what, and why of the user story are parts of the user story statement that describe who the user is, what they want or need, and why they want or need it. The who, what, and why of the user story are not meant to provide detailed information about how the user story will be implemented or tested. The definition of done of the user story is not a component that the business analyst should review and revise to provide more clarity to the QA team. The definition of done of the user story is a set of criteria or standards that indicate when a user story is completed and ready for deployment. The definition of done of the user story is not meant to provide specific information about how the user story will be tested or validated. References:
