If the phrase "if it ain't broke, don't fix it" was true, the aviation industry would still be living in the stone ages inventing the wheel. Changes are necessary to improve processes. But without conducting analysis' of proposals, it is possible that the outcome is not as great as expected. In the days before SMS, it was still acceptable for accidents to generate great improvements to flight safety. Prior to an unexpected accident the operation appeared to functioned perfectly and wasn't fixed, since it wasn't broken. What was forgotten is that it's "what you don't know that is what will surprise you."

In the farming industry, growing grain seems to be a simple process by placing the seeds in the ground, wait for rain for a great crop, or worry about hot and windy for a poor yield. If the crop regularly gave poor yield, the solution was to move to a more fertile ground. For centuries this method was accepted as not being broke, and therefore wasn't fixed.
One day a visionary from Iowa decided that seeds should be made more reliable to produce higher yields in hostile soil. This was a new way of thinking since the way farming was done had worked since beginning of time. However, by his new forward looking thinking he could feed the world, where the world couldn't feed itself. He had fixed what wasn't broke and was awarded the Nobel Peace Prize.
Aviation industry in the past lived by this principle "if it ain't broke, don't fix it". It wasn't until the Safety Management System (SMS) was introduced that forward thinking became a tool for planning, tracking and analyze results. With SMS the principle changed to "if it ain't broke, don't break it." SMS became the tool to develop better processes and to maintain well functioning systems. SMS changed organizational thinking from a rush to judgement by changing out the crew whenever there were incidents, to either analyze and repair the process, or to develop, implement and maintain a new process.
|Looking behind you in the past life was perfect, but look the other way and the unknown may surprise you|
If the old way of replacing crew to improve safety was true; then how many crew changes are required for the process to become perfect? Or look at it from an everyday prospective; if the toast was served burned, how many burnt toasts must be served for it to be perfect? Or, is it possible that rather than adapt to burnt toast, the day would be brightened by changing the way we make toast?
