Question

Based on an analysis of the current process stability and capability (Yield/PPM): which of the following would you most likely recommend for future monitoring of this process? Continue to use the current sampling plan as the process is in-statistical control and the control limits are within specification Using the same plan for collecting data (2 per batch) but switch to an X-bar and Range Chart to more quickly identify out-control conditions Change their sampling plan to include at least one part per cavity to form a subgroup until they can demonstrate that the four cavities are producing consistent parts Adopt 100 percentage inspection of all parts

Explanation / Answer

c. Change their sampling plan to include atlease one part per cavity to form a subgroup unitil they can demonstrate that the four cavities are producing consistent parts.

The subgroup in yeilding helps to focus on diversified features and helps to get control over sampling of more items. The features in terms of variance and standard deviation from the process can be better aligned through different sampling plans. This also drives to get better yeild per Parts per million (PPM)
