A business analyst in organization Y is assigned to elicit requirements in a project within a defined timeline. The business analyst has identified and invited key stakeholders to a requirements workshop. However, the stakeholders are not giving clear and concise requirements; their opinions about requirements are changing and conflicting with each other in the meeting. In the end, the business analyst could not elicit and define the requirements and therefore adjourned the meeting.
Which tool or technique could have been used by business analyst to avoid this situation?
