Define 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.
- 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, 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
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.
- 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. 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.
