Question
Mike Schmitt bought Johns Mechanics Service. John told Mike that the service process that has three sub-processes – diagnosis, repair and customer delivery. He also mentioned that each of the three sub-processes met internal goals exactly at 95% error-free rate. a) What is the error-free percentage as experienced by the customers for the entire process? b) Mike sets a target of 95% of error-free outcomes for the entire process. Assuming all the three sub-processes achieve the same exact error-free rate, what error rate each error process should achieve to reach Mike's goal for the entire process?
Explanation / Answer
a) What is the error-free percentage as experienced by the customers for the entire process?
error free % = 95 %
b) Mike sets a target of 95% of error-free outcomes for the entire process. Assuming all the three sub-processes achieve the same exact error-free rate, what error rate each error process should achieve to reach Mike's goal for the entire process?
error rate each error process = 95 / 3 = 31.67 %
