AlCapone: Consider determining the responsible party according to their ability to deal with the complexity of collecting and analyzing the information required to determine your process capability index. For expample: * Reflow oven: Fairly simple, just run a profiler, record the data, determine process stability and control, and calculate the index. * Placement machine: Fairly complex, place glass components on glass board, compare placement with expectation, record the data, and calculate the index.
There was an OnBoard Forum last Spring on this topic. It was a bit commercial and superficial for our taste, but there maybe some snippets of information there for you. Consider reviewing those threads.
