Managing Stream Overview Reports

The Stream Overview Report displays a compilation of different statistical metrics, including fallout metrics, capability indices and net content control values, as well as the new Composite Quality Score (CQS) metric, which combines variable and attribute violations into a single metric.

When you select the parameter set on the dashboard, it will affect the contents of this tile.

  1. In the aggregated dashboard toolbar, select Add Tile and then select the Stream Overview Report.

  2. In the Stream Overview Report, you can do the following:

    • Selecting Parameter Sets

    • Using this procedure, you will classify the data into nested categories contained in two analysis profiles, Site and Feature.

      If you select By Shift in the parameter set's time window, Enact will have aggregated data upon the last shift change, and will be able to categorise by shift. If you select Dynamic Time or Static Time in the parameter set's time window, Enact hides the shift level. For more information, please see Creating Parameter Sets.

      1. In the Stream Overview Report, select More and then select Define Levels.

      2. In the Define Levels dialog box, do the following:

        1. In the Analysis Profile data field, select the desired profile:

          • Display site-based data, with site as the highest level, in the following nested order:

            • Site. (default) Categorise the data by site.

            • Shift. Categorise the data by shift.

            • Process - Tag. Categorise the data by process tag.
            • Process - Name. (default) Categorise the data by process.
            • Feature - Tag. Categorise the data by feature tag.
            • Feature - Name. (default) Categorise the data by feature.
            • Part - Tag. Categorise the data by part tag.
            • Part - Name. (default) Categorise the data by part.

          • Display feature-based data, with feature as the highest level, in the following nested order:

            • Feature - Tag. Categorise the data by feature tag.
            • Feature - Name. (default) Categorise the data by feature.
            • Part - Tag. Categorise the data by part tag.
            • Part - Name. (default) Categorise the data by part.
            • Process - Tag. Categorise the data by process tag.
            • Process - Name. (default) Categorise the data by process.

            • Shift. Categorise the data by shift.

        2. Select Apply.

    • Using this procedure, you will expand the nested levels to show the contents, if any.

      To expand all levels, select Expand All.

      1. In the desired Stream Overview Report level, select Expand.
      2. The collapsed level expands.

    • Using this procedure, you will collapse the nested levels to hide the contents, if any.

      To collapse all levels, select Collapse All.

      1. In the desired Stream Overview Report level, select Collapse.
      2. The expanded level collapses.

    • Using this procedure, you can open charts from the Stream Overview Report.

      To locate the Chart button, you must expand to the Part level in the Stream Overview Report.

      1. In the Chart column of the desired data stream, select Chart.

      2. In the chart selection dialog box, select the desired chart:

    • Using this procedure, you will maximise the Stream Overview Report on the dashboard.

      1. In the Stream Overview Report, select More and then select Maximise.
      2. The Stream Overview Report maximises.

    • Using this procedure, you will restore the Stream Overview Report to its original size.

      1. In the Stream Overview Report, select More and then select Restore.
      2. The Stream Overview Report restores to its original size.

    • Using this procedure, you can roll up subprocess data, viewing the individual subprocesses.

      1. In the Stream Overview Report, select More and then select Aggregate Subprocess Data.
      2. Locate and expand the parent process for the subprocesses, and then select Subprocesses or the subprocesses counter.

    • Using this procedure, you will control the columns that Enact displays on the Stream Overview Report.

      1. In the Stream Overview Report, select More and then select Configure Columns.

      2. In the Configure Columns dialog box, select the desired tab and then select the desired columns:

          • Category. Based on selected Analysis Profile in Defining Levels above, Enact organises by site or feature.
          • # Subgroups. Total number of subgroups.

          • USL. Upper Specification Limit.

          • Mean. Arithmetic average of a given data set, where N represents the number of values in the data set. ClosedFormula

          • SD(ST). Short-term process variation estimated from either the within-subgroup standard deviation (for n > 1) or moving standard deviation (for n = 1) of the subgroups. ClosedFormula

          • SD (LT). Variation representing the average deviation of values from their mean, often called the RMS (root mean square) method of calculating sigma. ClosedFormula

          • # <LSL. Number of measured values below the lower specification limit.
          • # >USL. Number of measured values above the upper specification limit.
          • # OOS. Number of measured values outside the specification limits.
          • % OOS. Percent of measured values outside the specification limits.
          • # Defects. Number of defects, weighted by code weight.

          • # Defectives. Number of defectives, weighted by code weight.
          • % Defectives. Percent of defectives.
          • % CQS. (Composite Quality Score) Percent of out-of-specification measured values (total count of out-of-specifications at time of aggregation, regardless of triggered events), defects, and defectives that can be rolled up across any level. A higher CQS indicates worse performance.
          • CQS (PPM). (Composite Quality Score) Total out-of-specification measured values (total count of out-of-specifications at time of aggregation, regardless of triggered events), defects, and defectives expressed in terms of parts per million, calculated by the actual total percentage multiplied by a million. A higher CQS indicates worse performance.
