Analyzing "what if" scenarios is part of which process?

Analyzing "what if" scenarios is a crucial aspect of documenting functional requirements. This process involves determining how different conditions affect the behavior of a system. When functional requirements are being documented, it’s essential to consider various scenarios—what happens if certain inputs are changed, if a specific decision rule is applied, or if certain external factors come into play. This analysis helps ensure that the requirements are comprehensive and cover all possible variations that may affect system performance or user experience.

In the context of functional requirements, this type of scenario analysis helps identify the desired behavior of the system under various circumstances, ensuring that stakeholders' needs are met. It also aids in validating the system's capabilities and ensures that all interactions are well understood and correctly implemented. This detailed understanding is pivotal in guiding development efforts, testing strategies, and user acceptance criteria.
