I like the way this guy thinks. Don't EVER move from point A to point
B without the ability to move back to point A.

Back in the 70's [I think] RCA (or was it GE?) had a recipe for an RF
transistor that was 'knock your socks off' fast, low noise, low power
{for RF] and cheap to make. It was head and shoulders above any
competitor. As you can imagine the demand was incredible. To gear up
Production, the Management built a huge facility with the required
increased through-put capability across the street from the smaller,
original facility. Not sure why, or how, but the original line was
shut down and dismantled before the new line was operational, probably
to save a few coins on the furnaces and clean room equipment to be
used in the new facility. Starting up the new facility, it NEVER
produced product that recreated the specs of the original transistor,
could never make transistors as fast, anywhere near the low noise, and
there was essentially no yield out of any run. In other words, they
had lost the recipe. It is my understanding that no one ever found
out why. Since they had dismantled the original facility, there was
no way to even go back to making smaller quantities to keep hold of
the market. Thus, I always hear ringing in my head, "Don't move from
point A to point B, destroying point A. You may need to return to
point A."
