Reliability is defined as the ability of a part or product to perform as intended (i.e., without failure and within specified performance limits) for a specified time, in its life cycle application environment. Over the years, numerous methodologies have been developed to predict the reliability of electronic parts and equipment. However, both the customer and the equipment supplier should realize that the benefits of a reliability prediction are dependent on the accuracy and completeness of the information used to perform the prediction and on the methods used to conduct the prediction. In other words, the usefulness of a reliability prediction depends on how the prediction is developed and how well the prediction is prepared, interpreted and applied. As a result, the IEEE Reliability Prediction Standard 1413 was developed to understand the risks associated with using a prediction and to establish the framework around which a reliability prediction methodology should be developed. This paper describes the development, activities, and contributions of the IEEE Reliability Standards Group in the field of reliability prediction.
