This answer states that following these steps is the process that the BA should follow to draft and finalize the requirements for implementing a new Service Cloud feature for Cloud Kicks. Reviewing information from the discovery means that the BA revisits the information or data that was collected during the discovery phase, such as business goals, stakeholder needs, pain points, opportunities, etc. Asking clarifying questions means that the BA seeks to understand and verify the information or data that was collected, and to resolve any ambiguities or conflicts among them. Drafting requirements means that the BA writes down the statements that describe what the solution must do or have to meet the business goals and stakeholder needs. Refining and confirming requirements means that the BA revises and validates the requirements with the stakeholders, and ensures that they are clear, concise, consistent, and complete. Prioritizing which requirements will be included in the minimum viable product means that the BA determines which requirements are essential or desirable for delivering a solution that provides value to the stakeholders, and which requirements can be deferred or excluded from the scope.
