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 frequancy 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.
