Which methodology helps in problem-solving by eliminating possibilities?

Deductive reasoning is a logical methodology that focuses on drawing specific conclusions from general principles or premises. This approach helps in problem-solving by starting with established facts or theories and then applying them to specific cases to determine their validity or applicability.

In the context of eliminating possibilities, deductive reasoning works effectively because it allows a technician to take known information and apply it systematically to narrow down potential solutions. For instance, if a certain hardware component is known to cause a specific issue, a technician can deduce that if that component is not faulty, then it is eliminated from the list of potential causes for the problem at hand.

The strength of deductive reasoning lies in its structured approach: it relies on logical steps and clear evidence, making it easier to pinpoint the root of an issue by systematically eliminating options based on known facts. This methodical elimination is a valuable skill in desktop support and other problem-solving contexts.
