It may be a language thing but I read FTY as the first outcome of the process that may be controlled by GP-12 (early production containment).

Dear Al,
If I'm not mistaken, FPY of a process is the ratio of the parts produced without defect "first time" to the total no of parts produced. In other words:
FPY = (parts produced without defects first time / total number of parts produced)*100
"Fisrt time" refers to products without a need for repair, rework etc.
If FPY is what our friend lee01 means, then it is not difficult to relate it to Cpk.
