There’s Weibull, and then there’s Weibull Engineering (WE). The Weibull model was promoted originally by Waloddi Weibull before, during, and after the 1950’s. Weibull is the most widely-used probability model for how failure mechanisms affect product lifetime, key for problem analysis and problem solving and problem forecasting, but that’s not the only application. Although Dr. Weibull is no longer with us, his methods and insights carry on in countless new applications here in the 2000’s. WE extends the Weibull model to real engineering application throughout all product cycle phases especially for continuous improvement efforts.
