    Should USL and LSL  increase or decrease as we go to the finished end of the product?or  logically you can’t say anything about USL and LSL values at different stages?

    hey priya
    usl and lsl are specifications so they remain the same throughout the mfg proces…..u can only tighten the ucl and lcl as the product mfg process matures.
    usl and lsl are fixed by ur client or design team so they remain constant.
    anyways where r u working……i am a student in chennai doing my industrial engg.

    Your USL/LSL are your customer requirements.  It is the amount of variation your customer is willing to accept from the target.  It does not “change” as a result of anything your process does or does not do.
