Specify process targets and process limits for each measure

You can specify the target values and specification limits for each measure of a particular process for a particular product.
  1. Go to the Components page and select a product. Then select the process flow step of your product.
  2. Open the process step and go to the Process Summary section to access the target and specification limits.
  3. Enter values for the target, specification limits, and action limits for each measure.
    Indicates the setpoint of the process or product measurement. Often, the target is centered between the control limits (for an in-control process) or specification limits. You must enter a target value to calculate Cpm, a capability index that also considers how much the data deviate from the target.
    Lower specification limit (LSL) and Upper specification limit (USL)
    Indicate the minimum or maximum acceptable value for the product or service. To perform a capability analysis, you must enter a lower specification limit, an upper specification limit, or both.
    Lower action limit (LAL) and Upper action limit (UAL)
    Optional values that indicate an early warning sign to take action on the process. Usually, the LAL is greater than the LSL, and the UAL is less than the USL.
  4. Select Additional Settings to enter reasonable limits and absolute limits for each measure.
    Reasonable lower limit (RLL) and Reasonable upper limit (RUL)
    Indicate values that identify unlikely measurements. Reasonable limits are used to flag data entry errors.
    Absolute lower limit (ALL) and Absolute upper limit (AUL)
    Indicate values that identify impossible or extremely unlikely measurements. Absolute limits are used to prevent data entry errors. Reasonable lower limits must be greater than absolute lower limits, and reasonable upper limits must be less than absolute upper limits.
