Reviews and workshops are effective techniques for validating and negotiating requirements with stakeholders. They can help the BA to identify and resolve any conflicting or contradictory requirements, as well as to gain consensus and agreement among the stakeholders. Reviews can be done in various forms, such as walkthroughs, inspections, or peer reviews. Workshops can be used to facilitate collaborative discussions, brainstorming, and decision making among the stakeholders. Both techniques can help the BA to safeguard against conflicting requirements by ensuring that the requirements are clear, accurate, complete, and aligned with the business goals and needs123. References:

 A fishbone diagram is a technique that helps identify, explore, and display the possible causes of a specific problem or quality characteristic. It can also be used to analyze the root causes of a problem or a gap between the current and desired states of a solution. By using a fishbone diagram, the BA can understand the reason why the performance of the solution does not meet the expected benefits and identify potential corrective actions. References:

 Before meeting with the project sponsor, the BA must ensure that the requirements are atomic, feasible and testable. These are some of the characteristics of good requirements, as defined by the BABOK® Guide1. Atomic means that each requirement is concise and has a single meaning. Feasible means that each requirement can be implemented within the constraints and resources of the project. Testable means that each requirement can be verified and validated using objective criteria. These characteristics help to ensure that the requirements are clear, realistic, and measurable, and that they align with the objective of the project. References:
