Perhaps instead of ‘capable’ we should say ‘amazing’! A ‘capable’ process will essentially create products that have a very, very small chance of being defective. So how do we get here? SPC can help. But how do we measure how ‘capable’ our process is? And can we use this measurement to (for example) work out how many Parts Per Million (PPM) defects you are likely to get? This webinar introduces you to the concept of process capability including well known indices like CPK along with what this means for your process. [Read more…]
