Other Fish To Fry
DrHGuy is taking some time off from blogging to fry those other fish about which one hears so much, perhaps with a side of sour grapes and a hot potato or two.
In the meantime, readers are offered a powerful tactical tool, the Fundamental Troubleshooting Flow Chart, and the profoundly utilitarian philosophy it embodies.

The Troubleshooting Flow Chart
Problem-solving is clearly an essential skill, regardless of ones profession or socioeconomic setting. Thus, when I recently happened onto these versions of the Troubleshooting Flow Chart that depict this process at its most fundamental level, I recognized the opportunity and obligation to introduce them to viewers unfamiliar with the schematic and, more importantly, its powerful underlying concept.
The diagram at the top of this post (for best viewing click on charts) is said to have circulated on the internet before it was the internet1 but is nonetheless certainly a distant iteration of the original.2

The internet had a precursor, the ARPANET (The Advanced Research Projects Agency Net), and the consequences of its evolution from that beginning include some of the most beneficial, most cumbersome, most dangerous, and most creative aspects of the net. The Wikipedia article on this topic can be accessed at ~ Wikipedia: ARPANET ~ [↩]
- While the author of Version 1.0 will probably never be ascertained, my personal conviction is that Adam and Eve, after being cast from the Garden of Eden, paused, using accepted Quality Cycle methodology developed by their contemporaries, Deming and Juran, to reflect and review recent events with an eye toward performance improvement. 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? … [↩]
