Why should assumptions be minimized during troubleshooting?

Minimizing assumptions during troubleshooting is crucial because assumptions can lead to the oversight of critical factors that may be essential in diagnosing a problem. When a technician makes assumptions, they might not gather or consider all relevant data and symptoms, which can result in misdiagnosis and ineffective solutions. Each troubleshooting scenario can present unique variables, and sticking to verified information instead of presumed facts ensures that all potential issues are examined and addressed.

For instance, if a technician assumes that a specific component is malfunctioning without adequately verifying it, they could miss a related issue that may cause the same symptoms. Thus, by focusing on facts rather than assumptions, a more thorough and accurate troubleshooting process is ensured, ultimately leading to more effective resolutions.
