A medical device manufacturer is producing heart stents that must be between 18.00 mm to 20.00 mm in length. Since a heart stent is a small device that will be inserted into a vital organ, they aim to manufacture them as accurate and as precise as possible. A sample of 20 heart stents suggests their process is stable and capable with a narrow distribution, resulting in high Cpk (2.378) and Ppk (1.922) values.
