    Hello all,
    I am struggling to determine how to calculate our rolled throughput yield in our continuous chemical manufacturing process. We do not really have discrete steps to measure defects. Everything is also buffered and blended at several stages in the process so we lose the details on results per stage.

    Can we still use RTY or does final yield accurately measure our process performance?
    Thanks.

    When steps in a continuous process are all continuous you should sill have time-fenced yield data from each step. If you have that, you can do RTY over a time frame. It you don’t have it your quality control is deficient.
