We are in business to make money We make money by satisfying needs We are able to satisfy needs by doing Every need/do pair is an interaction The aim of customer focus is on improving need/do interactions Repetition of the same action constitutes a process Improvement of our business means improvement of our processes Customers need products/services ontime, with zero defects, at the lowest cost Suppliers create processes to generate needed products As process capability improves, the product quality increases As quality increases, costs and cycletime go down The attributes of customer satisfaction must be measured if they are to be improved To improve means we must be able to predict and prevent, not detect and react Prediction is correlated to certainty Maximization of certainty is dependent upon the measurement of process capability Process capability is best understood and reported using statistics Statistics is dependent upon data Data must be collected in the process according to a plan Statistics is used to convert raw data into meaningful summary information Statistical information is used to report on, improve, and control the process The basis of statistics is the mean and standard deviation The mean reports on process centering The standard deviation reports the extent of variation or scatter about the mean By bining the mean and standard deviation, the sigma of a process can be calculated The sigma of a process tells us how capable it is The process sigma can be used to pare similar or dissimilar processes Such parison of processes is called benchmarking Benchmarking is a petitive tool used to uncover what we do well and not so well Once basic petencies and deficiencies are know, corrective action can be taken Corrective action leads to the reduction of defects, cycletime, and cost The reduction of defects, cycletime, and cost leads to improved customer satisfaction
