    Process Capability Baseline (PCB) a documented
    characterization of the range of expected results that would normally be achieved by following a specific process under typical circumstances.

    Re: PCB

    UCL and LCL can be computed as follows

    Compute mean and standard deviation for the data points for a particular metric

    UCL = Mean + 3*S.D.
    LCL = Mean - 3* S.D.

    If the band is very large use 1 instead of 3 for S.D.

    It is advisable to have a minimum of 25-30 data points for computing UCL and LCL else set specification limits
