Q2. Process performance and Process performance index. which is a statical method to determine wether the process is capable for long run.
Ans. 
Process performance index is a statistical method to determine if a process is capable for long run.
• Process performance is a measure of how well a process is performing compared to its specifications.

• Process performance index (Ppk) takes into account both process centering and process spread.

• A Ppk value of 1 or higher indicates that the process is capable for long run.

• If Ppk is less than 1, the process may need improve...read more
