Answer:
<em>A. 1.111</em>
<em>B. The process is not capable</em>
Explanation:
Part A
Capacity index help to determine the performance of a process and how it could perform in the future. A capacity index of above 1.33 means that the process is capable but a capacity index below 1.33 means that the process is not capable. The capacity index can be calculated using equation 1;
From the mean which is 0.5, it can be determined that the process is a centered process.
For centered process, the mean = 0.5 x (Upper s. - Lower S.) = 0.5 x 0,02 = 0.04
so the capacity index for centered mean will be used
................................................1
Given standard deviation = 0.003
upper specification = 0.05
lower specification = 0.03
Therefore the capacity index of the process is 1.111
Part B
The capacity index of the process is 1.111 and it is less than 1.33, this means that the process is not capable.
