Hello,
Would be interested to get more feedback on my input.
1. High precision because most of the points are close to each other.
2. Low accuracy because most are away from/above the mean (x bar) specified.
3. I think X bar shown is a clue. X bar means statistical mean (sum of value of all points /no of points).
4. It's stated that the machine is high accuracy high precision, so reliable measurement.
5. So the process is good, but representation in the control chart may need adjustment (adjustment of limits, and subsequently, the mean).
6. The actual mean (x bar) may be slightly higher.
7. Adjustment may mean adjustment of the chart and improvement may mean improvement of the process.
Will be great to understand a Quality Guru's perspective.
Thanks
