Did you hear a story about how several blindfolded people were tasked with describing an elephant? All disagreed with the others because the only information they had was what each experienced directly. The person touching the trunk described how an elephant was like a large snake. The person touching the leg described how an elephant was like a tree.

Descriptions of the tail and the flank of the elephant produced further contradictory descriptions. Each description was accompanied by the emphatic assurances of the person providing the description that their description was correct, because that is the only first-hand ex¬perience that person had of an elephant. To add confusion, they all agreed on what the skin felt like. This story has the same point while you are on learning about the LAN.

If the person troubleshooting does not have a working knowledge of the technology, adequate information gathered from multiple points or information sources, or is lacking experience for a broader interpretation, then incorrect assumptions and conclusions are made. The accuracy and speed of troubleshooting depends on the knowledge, skill, and experience of each techni¬cian involved, and the tools at their disposal. It sometimes requires interpretation by an uninvolved third party who is able to provide an objective opinion.
