I firmly believe in the K.I.S.S. Principle (Keep It Simple Stupid!).
Way back in the mid 80's and old guy name Walt at then Martin Marietta taught me the Principle, and I've used it ever since. The idea is to keep things as simple as possible, making them no more complicated than they absolutely have to be.
Around that same time (mid 80's) me and my friend Joe (a fellow engineer) had to go to the Ocala plant to fill in for another engineer (who could not go for some unrecalled reason) to get an ESS Station (Environmental Stress Screening) up and running. Well, it turns out that the station violated the K.I.S.S. BIG TIME. The idea was to vibration test 18 circuit boards at the same time. The buffoon designer of the vibration fixture had it where you mount the circuit boards to be tested onto backplates, and then slide the fixture slots, and then hydraulically clamp the backplates into place.
Trouble was, the vibration data showed that unclamping and reclamping the backplates got totally different vibration data from previous data, meaning the clusterf... of a vibration fixture was totally unusable. The sheot hit the fan when we reported the problem to Management.
So, Joe and I did some research, and found out that they needed to test nowhere near 18 cards at a time; that testing only 6 cards at a time was just fine. So we designed a simple, solid block, that held 3 card on front and 3 on the back. Worked perfectly!
Applying the K.I.S.S. Principle to other aspects of life, I find that it is best to believe in what is real, rather than in what "might" be real. Life is too short to chase your tail over stuff that might not even be real.
