True

The core objective in six sigma is to reduce variation in processes. TrueFalse

Suppose that the design engineering team set the specifications for length of a stamped sheet-metal part at 10 inches (T) with acceptable tolerances of ±.05 inches (USL and LSL). The average length of the products produced by the actual stamping process is 9.995 inches (m) with a standard deviation of .005 inches (s). What is your Cp? 9.99 3.33 1.11 0.888 10.00

How is the statistical concept of six sigma used? Uses tools to help you identify which type of variation is present in your processes as well as how to address that variation to improve your process Meets adjustments to change or switchover the type of products produced on a manufacturing line Consistently meets established quality, cost, delivery, financial and cost objectives Partners between distribution channel members that changes the traditional replenishment process from distribution-generated purchase orders

Uses tools to help you identify which type of variation is present in your processes as well as how to address that variation to improve your process

Six Sigma is built on which very critical fact? It takes time for cash to flow back into the company after it has been spent Capacity should be understood and defined for each level in the organization Variability in a process produces defects, errors, and waste Mannerisms are inherent in human acts during the purchasing process

Variability in a process produces defects, errors, and waste
