Define Sample Frequency Trigger
Explanation
This activity is used to define which sample frequency trigger types will be used for a specific control plan
template or control plan. Triggers are used to create analyses at certain events or time intervals.
The following trigger types are pre-defined for Control Plan - Manufacturing:
- Start Shop Order
- Start Operation
- Nonconforming
- Time Interval
- Acceptance Sampling
The following trigger types are pre-defined for Control Plan - Purchasing:
- At Arrival
- Time Scheduled
- Interval Scheduled
- Nonconforming
- Acceptance Sampling
Triggers can only be entered, modified, or deleted as long as the control plan template or control plan is in
the Created status.
- The Start Shop Order, Start Operation, Nonconforming and At Arrival trigger
types can only be defined once for a specific control plan template or control plan number.
- The Time Interval, Time Scheduled and Interval Scheduled trigger types
can be defined more than once for a specific control plan template or control plan number. However, they have to
be unique.
- Entering values in the Value and Unit of Measure fields is required if the trigger type is
Time Interval or Time Scheduled.
- Entering a value in the Value field is required if the trigger type is Interval
Scheduled.
- The Acceptance Sampling trigger is system-generated and connected to the data point when the
acceptance sampling inspection code is used and can only be used with that inspection code.
To define a sample frequency trigger click the new command in the Define section on
the Sample Frequency Triggers tab, enter information about the trigger and click
Save.
Prerequisites
The control plan template or control plan for manufacturing or purchasing must be in the Created
status.
System Effects
As a result of this activity, the defined triggers can be connected to data points. Analyses will be created
automatically, depending on the defined sample frequency triggers.
- Start Shop Order - This trigger creates an analysis when the status of the shop order is changed to
Started.
- Start Operation - This trigger creates analyses automatically for each operation when the
operation status changes into “Partially Reported” or “In Process”.
- Nonconforming - If an existing analysis is not fully expected, i.e., when the Variable Result
Status field has the Out of Specification or Partly Within Specification value, the Attribute Result
Status field has the Nonconformities Exist value, or the Category Result Status field has the
Nonconformities Exist value, this trigger will automatically create an analysis to assure 100% inspection.
- Time Interval - When the routing operation is started, this trigger type creates an analysis by the
defined time interval, for example, every 10 minutes. For example, if you entered 1 in the Value field and
Hours in the Unit of Measure field, the time interval between creating two analyses will be one hour.
This will continue as long as the status of the routing operation number is Partially Reported. The analysis will
only be created during working hours.
- At Arrival - This trigger creates an analysis at every receipt, according to the data points defined
for the trigger.
- Time scheduled - This trigger creates an analysis when the next receipt is made after the time
interval is reached since the last analysis was created. For example, if you entered 2 in the Value field
and Days in the Unit of Measure field, an analysis will be created two days after the receipts are
made.
- Interval Scheduled - This trigger creates an analysis when the value defined in the Value field
is equal to the number of receipts made. For example, if you entered 3 in the Value field, an analysis
will be created after three receipts are made.
- Acceptance Sampling - With shop orders, this trigger creates an analysis when the status of the shop
order is changed to Started. With purchase orders it creates an analysis at receipt. The system will decide if it
is necessary to create an analysis and calculate the sample size according to the setup of Standard,
Inspection Level, Acceptance Quality Limit (AQL) and Sampling Plan on the control plan.
