Notes

Troubleshooting is the problem solving process we go through when something is broken. Typically, it involves a search for the source of a problem or faulty components that are causing a bigger system to not work properly. This search can be conducted in a variety of ways.

Logical thought processes like cause and effect, process of elimination, and starting with the simple possible causes can save a lot of time and headache.
