With that in mind, you need to pool all your technical knowledge about how your subsystems work and interact with each other. When you encounter a problem, you need to put on your scientist's lab coat and hypothesize where that problem is coming from. If you combine the scientific method of testing your hypothesis (make only one change at a time, please) with the concept of divide and conquer, you can isolate the problem to a subsystem. Repeat the process and isolate the problem to part of a subsystem. Keep repeating the process until you know exactly what the problem is. That is a systematic approach to troubleshooting.

In a best-case scenario, taking a random approach will take you longer to isolate and fix the problem. And in a worst-case scenario, your problem will get worse.

In this chapter, we examine a systematic approach to troubleshooting. Additionally, we discuss taking a proactive stance to prevent problems before they happen.
