Process capability indices are pretty well documented. Consider:

1 A good general SPC book like: Statistical Quality Control; EL Grant & RS Leavenworth; Mcgraw-Hill; ISBN 0078443547

2 Other good books are:

Statistical Process Control For SMT; WS Messina [check last month's SMTnnet Newsletter for a review and other information on this book]

Process Capability Indices In Theory And Practice; S Kotz & CR Lovelace; Arnold; ISBN 0340691778

3 Search the internet using your favorite brouser

4 Read pertinent articles on: and poke around their site for some other good stuff
