    Oh no you say—not more management speak! Please, I get enough of that already! Fear not; we promise that we won't waste your time with YAUM (Yet Another Useless Methodology). We want you to find your problem and fix it quickly. So you can call this a process, a method, a way, or if you like, call it a methodology—whatever works for you. What we don't want to do is fill your head with some useless babble. This methodology is hard won from years of solving problems.

    It all started many years ago. Painted on the wall of our parents' garage was a slogan: "1st law of wrenchin': always check the spark plugs!" Scott painted this on the wall as a reminder of a valuable lesson we learned as teenagers. You need a plan for fixing things, and you need some "laws" to make sure you don't waste a lot of time figuring out what your problem is when it's staring you in the face.
