For starters:

First Time Through (FTT) - http://www.axiom-adal.com/firstime through.html
Definition: First Time Through is the percentage of units that complete a process and meet quality guidelines the first tie without being scrapped, rerun, retested, diverted for off-line repair, or returned. It is a measure of the quality of the manufacturing process.

Dock to Dock (DTD) - http://elsmar.com/Forums/showthread.php?t=60388

Also see FORD Acronyms (aka 'Initialisms' - Not Always True Acronyms) List - http://elsmar.com/Forums/showthread.php?t=23774

Hopefully some of the others here can help with more specifics.

Unfortunately the "EFCOG" organization took down those materials a few years ago. I've attached an updated version of how to choose metrics.
Steve,

Slide 10 has a dead link to a file in which I was interested. Do you still have access?

Sure. Attached. This is from a course on "measures of effectiveness" at the US Naval Postgraduate School.

I really should figure a place to put these files. Should start a library here on the Cove.

It's off to the Chalk River Site next week, and I'll also be doing an ASQ talk for the Ottawa Valley Section at the end of the month.
