Impact Analysis

Definition

Impact analysis is the process of assessing the potential consequences of changes within a system, focusing on how modifications can affect various elements and stakeholders. This evaluation helps in understanding risks, costs, and benefits associated with a change, guiding decision-making to ensure successful outcomes. It plays a crucial role in managing requirements, configurations, and system performance throughout the lifecycle.
