Overview

During the first phases of a product's development, the estimate of the product's final reliability is called the "reliability goal." However, the first prototypes produced will almost certainly contain design, manufacturing and/or engineering deficiencies that prevent the product from reaching that goal. In order to identify and correct these deficiencies, prototypes are usually subjected to a rigorous testing program and appropriate corrective actions are implemented to improve the design. This structured process of finding reliability problems and monitoring the increase of the product's reliability through successive phases is called "reliability growth."

This tutorial addresses the principles of reliability growth testing and data analysis, including techniques to analyze data from time-based tests (where corrective actions may be implemented during the test, after the test and/or not at all) and from various types of one-shot success/failure tests.
