Explanation
A use case is a type of documentation that describes how a user interacts with a system to achieve a specific goal. It is written from the user's point of view and follows a standard format of "A [user role] wants to [goal] by [steps]". A use case helps to capture the user's needs and expectations from the system and provides a basis for developing test cases and acceptance criteria. A BA should use use cases to document how users will interact with the system and what outcomes they expect from it.

Requirements are statements that describe what a solution must do or have to meet the needs and expectations of the stakeholders or users. Requirements may change over time due to various factors, such as business goals, market trends, customer feedback, or stakeholder preferences. Using the previous VP's requirements without validating them with the new executive may result in a solution that does not align with their vision, strategy, or value proposition.

This answer provides an example of effective acceptance criteria for the scenario of creating an approval process on contract submissions. Acceptance criteria are statements that define the conditions that a solution must meet to be accepted by the stakeholders or users. Acceptance criteria should be clear, concise, testable, and measurable. This answer meets these criteria by stating what a sales manager wants to do (be notified, approve or decline), when they want to do it (when a contract has been submitted with a discount greater than
20%), and how they can verify it (a discounted price). References:

The correct order of phases in the implementation lifecycle on a Salesforce project is analyze, build, deliver, operate. In the analyze phase, the business analyst elicits requirements, maps business processes, and creates user stories. In the build phase, the development team configures and customizes Salesforce based on the user stories. In the deliver phase, the solution is tested, validated, and deployed to production. In the operate phase, the solution is monitored, maintained, and improved based on feedback and metrics. References:
