Explanation
A joint application design (JAD) is a technique that helps to validate the requirements with key stakeholders by conducting a structured and collaborative workshop that involves the business analyst, the project team, the end users, and the subject matter experts. A JAD can help to review the requirements for a new application that impacts various business processes, to confirm that the requirements are complete, consistent, and accurate, to resolve any conflicts or issues, and to obtain feedback and approval from the stakeholders. A team review is a technique that helps to evaluate the quality and accuracy of the business analysis deliverables by involving the business analyst and other project team members. A team review can help to identify and correct any errors, gaps, or inconsistencies in the deliverables, but it does not involve the key stakeholders who are affected by the new application. A brainstorming is a technique that helps to generate a large number of ideas or solutions in a short time by encouraging the participants to think creatively and freely. A brainstorming can help to explore different possibilities and perspectives, but it does not validate the requirements with key stakeholders. A product backlog prioritization is a technique that helps to rank the requirements or solution options based on their relative importance, urgency, value, or dependency. A product backlog prioritization can help to determine the optimal scope and sequence of the solution delivery, but it does not validate the requirements with key stakeholders.
