While validating requirements for a software implementation project, the business analyst (BA) needs to identify...

 Risk Analysis and Management is a technique that involves identifying, assessing, and treating the uncertainties and potential negative impacts that may affect the requirement or the solution. Risk Analysis and Management can help the BA to identify scenarios that would alter the benefit delivered by a requirement, because it can help the BA to quantify and prioritize the risks, determine the appropriate responses and mitigation strategies, and monitor and control the risk exposure and outcomes. Risk Analysis and Management can also help the BA to communicate and report the risk status and issues to the stakeholders and the organization, and to ensure that the requirement delivers the expected value and benefit. Metrics and Key Performance Indicators, Data Modeling, or Document Analysis are not the best options for identifying scenarios that would alter the benefit delivered by a requirement, because they are either too specific, too general, or not directly related to the risk analysis and management process. References:
