Trade-off analysis

Definition

Trade-off analysis is the process of evaluating and balancing different factors when making decisions, especially in the context of system performance and resource allocation. This concept is crucial for understanding how to optimize systems by weighing the benefits against the costs, risks, or limitations associated with various choices. It helps identify the most effective solutions amidst competing demands and constraints.
