An immediate purpose is to earn a living. You also may suggest the work is to improve the reliability of the product or system. Reduce downtime, reduce warranty, increase profit, etc.
That is fine for the overall purpose of reliability engineering work, yet in the day to day work, the specific task level, what is the purpose behind what we do? Continue reading
Some time ago when talking with someone I just met, the conversation turned to what we did for a living. I mentioned being a reliability engineer, and his response: “Oh, yes, we do reliability”. Curious, as I’m not sure that I ‘do reliability’, we then talked about what he meant.
The conversation revealed that they had a list of tasks that they accomplished for each product under development. They did tests and reviews of the results. A lot of testing. They did FMEA and HALT. He believed the engineers did derating or stress/strength calculation. He didn’t know about process stability with vendors or internal manufacturing lines. Continue reading
How is it that some people continue to get better at managing meetings, designing complex test plans, making presentations, or solving problems? How in general do people improve their performance over time at something?
Two Questions
Peter Bregman in a Harvard Business Review article (November 09, 2019) titled “If You Want to Get Better at Something, Ask Yourself These Two Questions” outlined the process. The first question is: “Do you want to get better?” If you accept your current performance then there is no need to go further. Continue reading
Uncertainty is another word for risk. Reliability uncertainty or risk is neither good nor bad, it just a bit unknown. Until we know the outcome, the eventual reliability performance, we will not know the impact.
So, how do we deal with reliability uncertainty? Will our product or system work as expected over time, or will it fail? Let’s examine a few of the common approaches in use and when and why the approach is effective. Continue reading
A plan is a road map toward a destination. It provide guidance toward a goal. The idea of a plan is to consider the path forward, the knowledge necessary to acquire, and the decisions along the way.
No plan is perfect other than those that successfully accommodate the successes and setbacks along the way. No plan can anticipate all the information yet to be uncovered, yet it can set a course to deliberately uncover what is necessary to move forward. Continue reading
