Reliability growth from the customer perspective [telecommunications]

Reliability growth is considered from the customer/user perspective. It is emphasized that the reliability that the first customer observed with the first customer shipping can be quite different from the reliability that a customer will observe with a unit or system produced five years later. A basis for controlling reliability growth and the elapsed time of growth for the various product life cycles is provided. It allows product management to adjust for breakthroughs or setbacks per phase to assure on-time delivery of products with selected reliability levels
