Process Capability (Capability) Cp The notion of understanding the concept of process capability is very important. This case is aimed at allowing students to review this important concept. A given process is under statistical study. The process average is 130, and its standard deviation is 8. The process specifications USL = 150 and LSL 100.

A. Calculate the Cp, after calculating yourself, please indicate in your words what the found value means. b. Calculate the Cpk, after calculating yourself, please indicate in your words what the found value means. c. Which of the 2 in index Cp, Cpk is better to measure the capacity of the process? Why? d. with the data supplied which% of defective products (% of product out of specifications) E. The company can centralize the process (Average = 125) which would be the Cp and Cpk value

F. With the achievement of the company to centralize the process, what would be the% of defective products (% of product outside the specifications) g. the company then centralizing the process achieves through process improvements reduce the standard deviation of the process to 6. Calculate Cp h. With this new achievement, what will be the% of defective products (% of product out of specifications) i. What would be the company's goal in terms of reducing the standard deviation to achieve 6 Sigma. j. After having done this exercise, reflect on the importance of the concept of process capacity and its relationship that has to do with the concept of 6 Sigma.
