The Troubleshooting Flow Chart
Problem-solving is an essential skill, regardless of ones job. So, when I happened onto the Troubleshooting Flow Chart that depicts this process at its most fundamental level, I recognized the opportunity and obligation to introduce it to any viewers who may be unfamiliar with the schematic and, more importantly, its powerful underlying principle.

The result was the prototype of the Fundamental Troubleshooting Flow Chart. In any case, it certainly fits:
OK, what happened? We had the Garden of Eden, which seemed to work fine. Then what happened? Then we screwed with it. And then? … [↩]
