Question

S. A company has just surveyed its customers and found that they expect its prodiu to weigh between 1.2 and 1.3 kilograms. The company believes that the long-tem variation of its products from its present production processes is 0022 km gram. a. Compute the process capability of the production process. b. Does the production process have the capability of meeting customer expec tations? Why or why not? What must be changed so that its production process has the capability of pro- ducing products within customer expectations? What new level of would make PCI c. d. 1.00?

Explanation / Answer

(a) production capability = {C (Pu) + C (pl)} /2

C(Pu) = (USL - mean ) / 3 standard deviation

= (1.3 - 1.25) / 3*0.022

= 0.05 / 0.066

= 0.7575

C (pl) = (mean - LSL) / 3*standard deviation

= (1.25 - 1.2 ) / 3*0.022

= 0.7575

Process capability =( 0.7575 + 0.7575 )/2

0.7575

(B) no, it won't be able to meet customer expectations as they lie between 1.2 to 1.3

(C) standard devudevia must be changed to reach that level

(D) PCI > 1

So 1 > 0.05 / 3* SD

3*SD > 0.05

SD > 0.0167
