Hi,
Here I see 2 key information
- You are inside the USL - LSL
- Base on the rule of 7, you don't have 7 consecutive points above or below
So it means it's high precision, the choice should be between A & B only
Next question is shall we improve or adjust?
as we are high precision and low accuracy : so you need to adjust
Conclusion : Option A,
You should not compare a target with a control chart, it's not the same logic here:
on a target you can't define which is the first, second.... dots... on a control chart you can. so it's the rule of seven that will tell you if you are precise or not.
