This paper demonstrates that many problems which are found in the design, production and delivery of products and services can be prevented when statistical tools are applied. Applying basic statistical concepts to extract and analyze process and test data permits decisions to be made proactively which eliminates causes and reduces variation. When results are predictable and variation is minimized; quality improves, costs are reduced and customer satisfaction increases. 1) Many problems can be prevented once you can see the variation 2) Sampling and Histograms show the extent of variation 3) Process Control Charts and Capability Metrics show you what the customer will see, and help prevent customer dissatisfaction.
