FMEA is a “before – the – event” action requiring a team effort to easily and inexpensively alleviate changes in design and production
Reliability may be defined as the probability of the product to perform as expected for a certain period of time, under the given operating conditions, and at a given set of product performance characteristics.
One important consideration when performing reliability studies is the safety of the product or the process. The criticality of a product or process changes drastically when human safety considerations are involved. Reliability test and studies can form the basis for safety studies.
It is the engineer’s task to define all of the previously –stated items, and in many instances, the engineer has only past experience and personal knowledge of like systems to define these different aspects of failure accurately.
