The Bathtub Curve and
Product Failure Behavior Part Two - Normal Life and Wear Out Part One of this article (presented in last month's HotWire) introduced the concept of the reliability bathtub curve. This is a graphical representation of the lifetime of a population of products, which consists of three key periods. Part One examined the first period of the curve, infant mortality, and also discussed issues related to burn-in, a common practice to reduce the occurrence of this type of failure during the useful life of the product. Part Two (presented here) will address the middle and last periods in the bathtub curve: normal life (or "useful life") and end of life wear-out. The normal life period is characterized by a low, relatively constant failure rate with failures that are considered to be random cases of "stress exceeding strength." The wear-out period is characterized by an increasing failure rate with failures that are caused by the "wear and tear" on the product over time. To read more, see

Reliability Benchmark Survey | |||||||||||||||
The
University of Warwick (United Kingdom) is currently conducting a detailed
and far-reaching survey of reliability practices, the "Benchmark Survey of
Timely and Cost-Effective Application of Reliability Techniques." ReliaSoft
is pleased to cooperate in this valuable endeavor as a sponsoring partner
and we encourage you to share your experience through participation in the
survey.
Companies world-wide, across all industries, are called upon to participate in the survey, which attempts to benchmark reliability activity according to the speed that reliability techniques deliver useful output, the quantity and cost-effectiveness of that output, its authority and accuracy and the uses to which the output contributes. This survey is designed to investigate the contextual factors that lead a project to choose specific reliability techniques, such as the project risks, corporate ethos, reliability staff organization and responsibilities, R&D investment, product complexity and criticality, timescales, customer involvement and many other factors. Upon conclusion of the survey, all participants will receive a report of the analysis results, general guidelines and individual comments. All surveys will be treated in confidence and will not be divulged to any other agency, either completely or in part, in any form that would permit identification of the respondent.
