Where I work, there's a level of affection for what is known as "Six Sigma," where people use what I (somewhat politically incorrectly) refer to as "an engineering approach" to solve tough problems. The name comes from the Motorola and then General Electric program whereby they wanted to ensure that light bulbs would fail less than three standard deviations from the mean. In English, that'd mean that if you bought a GE light bulb they hadn't bothered to test, it would light up for you 997000 times out of a million. Dilbert aside, I KNOW that six sigma works because I've used it to solve problems that have been around since before I got out of elementary school. I don't know that I care for all the "belt" mystical stuff, but there is substance beneath the BS, sure enough.
Anyway, part of "Six Sigma" is what is known as "THE FIVE WHYS." This is simply going down levels below the immediate problem you are having, to find out why that problem occurs and why THAT problem occurs and so on. It's sometimes hard to get below three whys, but even three is beyond what most people do. Even me.
THE FIRST WHY
My Cateye light wiggled - Why? It was loose in the bracket. Every Cateye bracket. That was the first why, and it was what prompted my post and the zip tie fix. Slap myself in the face! I'd forgotten to keep digging to deeper whys.
The SECOND WHY - Why was my Cateye light wiggling in every bracket? Because something had changed in the light. I didn't examine even down to the second why.
The THIRD WHY - Why did something change in the light? Because of the photo below.
Which brings up the FOURTH Why. Why did the front of the light bracket break? Because something acted to pull the light upwards at the front or push it down at the back. I'm not sure what that might be other than the on/off switch is at the top rear of the light. I've never smacked the thing intentionally, however. It's just gotten well used over the year I've had it. What's more, this pretty definitely looks a lot worse than it did even a couple of weeks ago. SOMETHING is chewing my light bracket up in the opposite direction of what might intuitively be expected.
We shall SEE what the Fifth Why reveals. Right now that light is at my LBS. Perhaps I will be a happy camper. Rain is in the forecast for Monday, so missing my light is not a big deal yet. Even should this drag until Tuesday, I have my cruddy Cateye 520 as a backup.
