How To : Run Skip Logic

With QM Skip Logic, companies can set patterns for skipping checks in quality measurement processes. These patterns let non-critical items "earn" a more relaxed inspection regime based on historic performance.

Define several skip patterns based on the classification of items. The starting point for a pattern is the ABC classification of an item, a combination of activity and turnover value.

To create or update a skip pattern:

  1. Choose the Lightbulb that opens the Tell Me feature icon (Alt+Q).
  2. Type Skip Pattern in the search box.
  3. Select New to create a new skip pattern, or select a line to edit an existing one.

Header: identifies the skip pattern

Field Description
Code Type a code for the skip pattern.
Description Describe the skip pattern.
Activity Class Select an activity class: A, B, or C.
Turnover Class Select a turnover class: a, b, or c.

Lines: one line for each level in the skip pattern

Field Description
Activity Class Filled automatically (first three fields).
Turnover Class Filled automatically.
Level Filled automatically.
Inspection Level Inspection and quality levels relate to the AQL/Zero Defects methods. The skip pattern level sets the AQL levels to a more relaxed or higher intensity level of inspection.
Quality Level See Inspection Level.
Accepted Receiving Events The number of receipts to process before a skip is allowed.
Skip The number of receiving events to skip.
Frequency The number of repeats of the receive and skip events before moving to the next level.
Reject Level The level to which the settings return when a rejected receipt occurs.
Max. Interval A date formula to set the period in which a frequency must be completed before moving to the next level. When not completed in time, the frequency is set to 0.

Skip Progress

The progress of an incident in a skip pattern is tracked in the Incident Entry to allow manual resets. The following fields track this progress:

  • Turnover Class: copied from the Item Classification Setup.
  • Activity Class: copied from the Item Classification Setup.
  • Active: indicates that this line is part of an active cycle.
  • Level: shows the current level in the skip pattern.
  • QC Status: Performed or Skipped. Shows whether the pending inspection needs to be completed or skipped.
  • QC Result Status: Accepted, Skipped, or Rejected. Shows the end result of the inspection from the registered measurement.
  • Closed by Date Interval: when checked, the frequency took longer than specified in the max. interval.

The "skip status" for an item/vendor is tracked in Activity Levels. For each item-vendor combination, the following data is tracked:

  • Current Level: shows the current level in the skip pattern.
  • Accepted Events: the number of accepted events in the current level.
  • Skipped Events: the number of skipped events in the current level.
  • Frequency: the frequency number in the current level.

Notes

  • When the item moves to the next level, the Accepted, Skipped, and Frequency numbers are reset.
  • When an item has cycled through the complete pattern and you want it to remain at the highest level, define a high frequency number (for example, 9999).
  • When there are receiving events while a measurement is still pending, the measurement for the new events is only created when the pending measurement is completed, to apply the correct skip logic.
