How might an understanding of components purpose input output and side effects help a repair person determine how to fix a product?

Understanding a component's purpose, input, output, and side effects allows a repair person to diagnose issues systematically. By knowing what each part is supposed to do, they can identify discrepancies in performance. Inputs and outputs help pinpoint which components may be malfunctioning, while awareness of side effects can reveal unintended consequences of a failure. This holistic view enables efficient troubleshooting and targeted repairs, ultimately leading to quicker fixes.
