Identifying risk is an important first step. It is not sufficient though.
Taking steps to deal with risk is an essential step. Knowing about and thinking about risk is not the same as doing something about risk. Continue reading
Once reliability risks have been identified and analyzed, we have to do something.
Well, not really.
If the risk is acceptable to the stakeholders, then we can simply continue with the current plan and monitor or any new risks or changes in our understanding of the existing risks. Continue reading
Making or supporting decisions involving product or system reliability is fraught with uncertainty. Is it reliable enough? Will failures occur prematurely? Are failures dangerous?
Uncertainty is risk.
In recent years more organizations and international standard bodies have focused on risk management. Identifying, analyzing, and mitigating uncertainty in a systematic manner. Continue reading
Did you hear what they said? Or, were you busy loading for your next verbal barrage?
As my mother would remind me, one should listen twice of often as speaking. Something about the ratio of ears to mouths in the population. I have to agree with her, that one can learn a lot by listening.
Listening may not seem to be a skill that one needs to master. Yet, how often have you walked away from a meeting where one or more participants obviously were not listening? How often are points repeated in an effort to be heard?
High temperature & humidity is a common test condition. For specific failure mechanisms there are models available (or you can create a model) to determine the translation from test to use conditions.
These acceleration models generally only apply to one specific failure mechanisms and do not apply to a system level estimate of life. If the failure mechanism is the dominate failure mechanism for the product, then an ALT exploring just that mechanisms would provide a life estimate. Continue reading
