Hello All,
I have a hard time understanding what the process capability indices mean? I hear > 1.33 is ideal but what exactly does that number mean? What if your Cpk is 1.5, 2.0, 3? I understand that process capability measures how well your process performs in relation to the specification limits, but the indices confuse me.
Can someone shed some light on this?
