Design for Service Life

Traditionally there has been a lot of confusion among people in the industry regarding Service Life versus Mean Time Between Failures (MTBF). The goal of this presentation is to discuss the difference and how to design for a service life. This includes calculating product service life using two approaches — first how to go about predicting the service life and second how to utilize the shipment and returns to determine the product service life. This presentation utilizes tools such as Weibull++ as a way to calculate the service life.

Key Words: MTBF, Service Life, Failure Rate, Cost of Ownership, Warranty, Customer Satisfaction
