Configuring Global Settings

Using this procedure, you will configure global settings, including dashboard refresh rate, units of measurement, Warning and Reasonable Limits auto-fill, default capability target values, tag groups to filter subprocesses, and potential and performance grades.

  1. Select Access Menu and then select Configuration | Global.

  2. Modify the contents under the following tabs:

    • Under the General Settings tab, you can configure the dashboard to refresh at a specified interval in minutes, as well as managing units of measurement (in, mm, lbs, kg, etc.).

      • Dashboard Refresh Section

        In this section, you set the frequency (in minutes) that Enact automatically refreshes its dashboards.

        1. Under the General Settings tab, locate the Dashboard Refresh Setting data field.
        2. In the Dashboard Refresh Setting drop-down list, select the desired refresh rate (minutes) of the dashboard analysis tiles.

      • Enabling USL/LSL display on Control Charts

        In this section, you can enable/disable a tenant level configuration that allows the users to show/hide specification limits on control charts (X bar, IXMS) in Enact. For more information, see Managing Display of Specifications Limit on Control Charts

        1. Under the General Settings tab, locate the Enable Control Chart USL/LSL display toggle.

        2. By default, the toggle is disabled.

        3. Enable the toggle to allow the user to show/hide the specification limits on the control charts.
      • Ppk calculation on Box and Whisker

        • In this option, you can configure the Ppk (process performance) formula to be either fallout-based or pooled sigma on the Box and Whisker tiles.

      • Use Process Time Zone

        By toggling this option on, you will make datasets queried for a given time window to be always localized to the process time zone rather than the user time zone. By default, this option is toggled off until you turn it on.

      • Handling Units

        Unit is the method used for evaluation. For example, inches (in) and millimeters (mm) are units of Length, Fahrenheit (°F) and Celsius (°C) are units of Temperature, and Pounds (lbs), Kilograms (kg), Grams (g), and Ounces (oz) are units of Weight.

          • Under the General Settings tab, select Unit.
          • In the Abbreviation column, type the abbreviation for the new unit.
          • In the Unit of Measurement column, type the name of the new unit.
          • In the Unit Type drop-down list, select the desired unit type. For example, Angle, Area, Count, Currency, etc.

          • In the Active column, do one of the following:

            • To activate the new unit, activate the Active slider.
            • To deactivate the new unit, deactivate the Active slider.
          • To add additional units, repeat the above steps.

          • To edit an existing unit, do the following:

            1. Select the desired field and type the new value (Abbreviation, Unit of Measurement) or select the new value (Unit Type).

            2. In the Active column, activate or deactivate the Active slider.

          • To delete an existing unit, select Delete and in the Remove Unit dialog box, select OK.

    • Under the Limits tab, you can type the value used to calculate and auto-fill the Warning and Reasonable Limits, and also set the default capability target values.

      • Specification Limits Section

        1. In the Warning Limit data field, type the default percentage (1% to 99%), which Enact uses to calculate the Warning Limits (UWL, LWL) using the Specification Limits (USL, TAR, LSL). For more information, please see Creating Manufacturing Limits.

          • UWL = TAR + p(USL − TAR), where p is the percentage value. If you have not defined USL, Enact will not auto-fill UWL.

          • LWL = TAR − p(TAR − LSL), where p is the percentage value. If you have not defined LSL, Enact will not auto-fill LWL.

          If you have not defined TAR, Enact averages USL and LSL, if possible. Otherwise, Enact does not auto-fill UWL or LWL.

          • Warning Limit = 10% or .1

          • USL = 2.85

          • TAR = 2.75

          • LSL = 2.65

          Therefore, UWL = 2.75 + .1(2.85 - 2.75) = 2.76 and LSL = 2.75 - .1(2.75 - 2.65) = 2.74.

        2. In the Reasonable Limit data field, type the default multiplier (1.01 to 50), which Enact uses to calculate the Reasonable Limits (URL, LRL) using the Specification Limits (USL, TAR, LSL). For more information, please see Creating Manufacturing Limits.

          • URL = TAR + m(USL − TAR), where m is the multiplier value. If you have not defined USL, Enact will not auto-fill URL.

          • LRL = TAR − m(TAR − LSL), where m is the multiplier value. If you have not defined LSL, Enact will not auto-fill LRL.

          If you have not defined TAR, Enact averages USL and LSL, if possible. Otherwise, Enact does not auto-fill URL or LRL.

          • Reasonable Limit = 2

          • USL = 2.85

          • TAR = 2.75

          • LSL = 2.65

          Therefore, URL = 2.75 + 2(2.85 - 2.75) = 2.95 and LRL = 2.75 - 2(2.75 - 2.65) = 2.55.

      • Default Capability Target Values Section

        Enact automatically updates Cpk and Ppk every 10 minutes, which means there will be a slight delay before you see recent changes.

        Set the default capability target values, including Cp target, Cpk target, Pp target, and Ppk target.

        1. In the Cp Target data field, type the company standard or desired ratio of the process variability (six sigma, short-term estimate) to the width of the specification limits (total tolerance). This ratio is used to calculate Economic Limits where actual process output performance is compared to the Cp Target, which should be between 0.01 to 9.99.
        2. In the Cpk Target data field, type the company standard or desired ratio of the process variability (three sigma, short-term estimate of sigma) to the width of the specification limit closest to the process mean, which should be between 0.01 to 9.99.
        3. In the Pp Target data field, type the company standard or desired ratio of the process variability (six sigma, long-term estimate of sigma) with the width of the specification limits (total tolerance), which should be between 0.01 to 9.99.
        4. In the Ppk Target data field, type the standard or desired ratio of the process variability (three sigma, long-term estimate of sigma) to the width of the specification limit closest to the process mean, which should be between 0.01 to 9.99.

    • Under the Reserved Tags tab, you can handle tag groups for subprocess filtering or run chart configuration.

      • Subprocess Selection Section

        Select a tag group to filter subprocesses in data collections that are configured to prompt for subprocesses. This allows you to limit the selection of an operator to only relevant subprocesses with the use of tag groups.

        • To configure a process with subprocesses, you must select Contains Subprocesses when creating the process.

          For more information about configuring processes, please see Creating Processes.

          Also, you must create a Tag Group and associate that tag group with the desired subprocesses.

          For more information about creating tag groups, please see Creating Tag Groups.

        • To configure a data collection to provide the operator with a subprocess checklist, allowing the operator to select the desired subprocesses, you must select Prompt for Subprocesses when configuring the data collection settings.

          For more information about configuring the data collection settings, please see Configuring Data Collection Settings.

        • To filter the subprocess checklist based on a tag group, you must select the tag group associated with the desired subprocesses.

        For example, if Mold 1 has subprocesses Mold 1A, Mold 1B, Mold 1C, and Mold 1D, you could configure Enact to collect data for Mold 1A and Mold 1C by selecting the tag group associated with those two subprocesses.

        1. In the Subprocess Selection section, locate the Tag Group data field.
        2. In the Tag Group drop-down list, select the desired tag group. HintClosedTo locate the desired tag group, begin typing a string within the tag group. For example, to locate Group Name, you can type gro or you can type nam.

      • Run Charts Section

        Select the tag associated with the desired features for the run chart dashboard. For more information, please see Managing Run Chart Dashboards.

        1. In the Run Charts section, locate the Feature Tag data field.

          • Select Tag.

            1. In the Tag Group drop-down list, select the desired tag group. HintClosedTo locate the desired tag group, begin typing a string within the tag group. For example, to locate Group Name, you can type gro or you can type nam.

            2. In the Tag drop-down list, select the desired tag. HintClosedTo locate the desired tag, begin typing a string within the tag. For example, to locate Tag Name, you can type tag or you can type nam.

          • Select Save.

    • Under the Grading Configuration tab, you can set the potential yield (A/B/C) grading threshold, which identifies what a process can yield, and you can set the performance yield (1/2/3) grading threshold, which identifies what proportion of the potential yield a process achieved. For more information, please see Understanding Grading.

      1. To set the potential yield (A/B/C) grading threshold, locate the Potential Grade section, and then do the following:

        1. In the Grade A field, type the minimum value for excellent results, which indicates Cp greater than 1.3 and low common cause variation. By default, Enact sets the value to 99.99.

        2. In the Grade C field, type the maximum value for action required, which indicates Cp less than 1.0. By default, Enact sets the value to 99.73.

        Enact automatically sets the Grade B field between the Grade A value and Grade C value, which indicates Cp between 1.0 and 1.3 and room for improvement.

      2. To set the performance yield (1/2/3) grading threshold, locate the Performance Grade section, and then do the following:

        1. In the Grade 1 field, type the minimum value for a centered distribution, which indicates minimal impact from external factors. By default, Enact sets the value to 95.

        2. In the Grade 3 field, type the maximum value for action required, which indicates a distribution that is considerably off-center or very wide. By default, Enact sets the value to 90.

        Enact automatically sets the Grade 2 field between the Grade 1 value and Grade 3 value, which indicates a distribution that may be slightly off-center or wider and room for improvement.
