NOT within the Scope
THE EMPHASIS:
Reliability and safety centered decisions
Any of the following is NOT considered within the scope. why this matters see the decision proceedings.
1.Knowledge about how to make decisions and/or a general decision-making process that lacks sufficient operational details
This is an example of how a set of real field return data look like after being processed and presented in a failure rate plot. It can be observed that the data fit a bathtub curve showing an early and then a constant failure rate phase of the product in this example.
2.Decisions made only for intermediate phases, tasks, and/or merely a portion of a system without a holistic consideration or assessment of an entire system-level effort and its goals which those phases and tasks are meant to serve
3.Decisions concluded on something beyond inference and deduction
4.Probability only, no statistics, considered sufficient for decisions
If you need to know whether your products, systems or assets in operation also exhibit a bathtub failure behavior, or if you simply need MTBF info to be extracted from field data for some reason, we can help, We provide a free service for a preliminary analysis. You can click here to contact us.
