Explanation
User acceptance testing is end-user testing performed in a sandbox or test environment to verify that a project or enhancement works as intended, and what was originally requested is actually being delivered. To ensure that the solution fulfills the needs of the sales team, the business analyst should choose subject matter experts as testers and prepare a sandbox with quality test data, test cases, and scripts that match real-world scenarios.
Subject matter experts are users who have extensive knowledge and experience with the business domain and processes. They can provide valuable feedback and insights on whether the solution meets their expectations and requirements. A sandbox is a copy of a production environment where users can test changes without affecting live data or users. Quality test data is data that is realistic, relevant, and representative of what users will encounter in production. Test cases are descriptions of specific scenarios or situations that users will perform with the solution. Test scripts are step-by-step instructions on how to execute each test case.

The group that the business analyst should include early in the scoping process is stakeholders. Stakeholders are individuals or groups who have an interest or influence in the project outcome, such as customers, users, sponsors, managers, team members, etc. Stakeholders should be involved early in the scoping process because they can help to define the project vision, goals, objectives, requirements, expectations, and success criteria.
Stakeholders can also help to identify any risks, issues, assumptions, or constraints that may affect the project scope. Involving stakeholders early in the scoping process can help to ensure alignment, engagement, and satisfaction with the project outcome. References:
