Exaggeration is a technique for solving comparative analysis problems by considering extreme perturbations to a system. For example, exaggeration answers the question "What happens to the output temperature of a heat exchanger if fluid flow rate increases?" by simulating the behavior of an exchanger with infinite flow rate. This paper explains the three phases of the exaggeration algorithm: transform, simulate, and scale. The transform phase takes a comparative analysis problem and generates the description of an exaggerated system. The simulate phase predicts the behavior of the transformed system. Finally, the scale phase compares the original and exaggerated behaviors to answer the original comparative analysis question.
