You know... (warning! long post!)

I've never thought about my problem-solving and troubleshooting skills as something special.

I just do what has to be done within the constraints of the problem. It's not a fixed process or anything in my mind that I do systematically. I know scientists who are painfully methodological, and can't see outside the box they've created for themselves. Sometimes you just can't remove all other variables (or keep them constant) and just vary the test variable. Sometimes you just don't know all the variables. How on earth can such a painful approach be cost-effective or realistic? But perhaps there's something to my skills, something I should consider as special, because there are so many books out there selling "total quality management" and "continuous improvement" process to improve one's products, services, and management techniques.

Now after a few days of considering a specific problem, and trying to find a written "bona fide" process that fits the description of how I solved it, I realized I might be a maverick (or a mad engineer). Perhaps it's out there, I just haven't found it yet.

I seem to have an innate knack of process definition and control, and can see when a system is out of order and fix it. I never thought of it as a process, but perhaps it is. A process then, is something that is more or less repeatable under similar circumstances, given variables X, Y, Z, input the process will output A, B, and C. (desired output(s), undesired outputs -- i.e. impurities and waste)). Ok, this is chemical engineering at its best. Of course A, B, and C have an optimal yield and each level has its costs. And getting rid of waste has its costs. Defining the process and defining when the process is out of specification (i.e. poor quality) is a business necessity and may not apply to simple challenges or "troubleshooting", such as those one may have around the house or in re-engineering/re-invention work.

I may not be as disciplined as a servo-mechanism or computer control system, but I know my systems and what it can measure and what it can not, what it can do and what it can't, what I can change, and what I can not, and how each one of the possible changes / measurements may or may affect the process output. I guess at the moment though, you could say that the "process of re-invention" is out of specification and some control (i.e. discipline) needs to be put on it so it comes back to its intended output.

Ah, then we have to come back to the philosophical side: What is Quality anyway? It's only how you define it in your process. Can you really measure 100% accuracy? No. Because it doesn't exist. Any statistician or mathematician worth his weight will tell you that. You can only ASSURE something with a certain probability is 'error-free' or within specification to a point. Say 10^(-6) assurance, that's 0.000001, I think, chance in 100 events. Say you have 10 million possible events: then with the above assurance level, 1 event will be out of specification. That's not bad at all. But of course if you are the one patient with that one failed device... well sucks to be you.

Quality in everyday life, is how you define it. I usually operate around 20-50% failure rate, depending on the subject or event. That's acceptable to me. I start to worry when I have a 99.9% failure rate, especially when it comes to publishing my writing. Ah, but then you only need one big break... you gotta play to win, so to speak.

For further reading on what is Quality please see "Zen and the Art of Motorcycle Maintenance".... apparently it was rejected over 450 times....

Anyway, my Re-Invention Process is out of control and out of spec. What do I intend to do about it? Do the best I can to get it back on line. There are other factors that I didn't consider and other players now want a piece of me (not paranoid really). Life happens. I've built enough padding into the process to allow for the major deviations. Things change. I ain't gonna get my panties in a wad. :-)

Now that's a pretty picture. Don't want to leave you with just that image.

It's a special talent to be able to critically think, problem solve, and troubleshoot. It's management on the fly. The best managers are ones who seem to solve a problem with a "win-win" solution at least 70-90% of the time, without letting anyone see them sweat. At the end of the day, you gotta live with yourself (and hopefully like yourself), be able sleep at night with your process control definitions and decisions. You gotta know what you want, when you want it, and at what conditions. You gotta have negotiables, and non-negotiables. You gotta have a good attitude about life, your work, and your processes -- whether mental, financial, physical, written down or in your head -- and realize you are in the greatest process of all -- the Learning Process. You can't stop that one!
