If you consider yourself an engineer, think about what you do in a very broad sense. Engineering is all about applying scientific discovery and making it practical, useful, and widely used.
If you are an Electrical Engineer, for example, then you are at some level of the electronics systems hierarchy building off of scientific discovery by making systems that address needs, solve problems, etc. If all we had to work with was the first version of every scientific bench experiment, we would not be able to build the systems we do today. The performance would not be sufficient for most problems, the costs would be huge, and certainly the reliability would be very poor. But focusing on making things cheaper is not enough, as it may still not perform well enough to be useful. And improve performance all you want, and it still won’t be of use if it continues to fail frequently, cannot be easily repaired, or does not meet mission needs, cannot be maintained, does not survive operation, etc.
Think about what you do as a professional, and I’ll bet you can generalize at least part of what you do as assuring the reliability of something. Even the scientists worry about reliability, as their experiments have to be repeatable for confirmation, and that is just a concern of reliability. Even the teacher is focused on improving the reliability of the students.
So if you are an engineer of any sort, even a scientist, a teacher, or a professional filling most any role for that matter, consider yourself to be a professional focused on reliability. And if you feel the need to improve on your own reliability, consider attending the 2014 RAMS® conference, the annual reliability and maintainability symposium, to be held in Colorado Springs in just a few months.
