Define identification for inspection points

In this step, you define the identification of inspection points.

To identify the inspection points, the inspection point data record can contain a date and time field. For each of these fields, there are two text and number fields of variable length that you can freely define. You use these fields when recording inspection results, to assign the inspection points to the units that have been inspected.

You can use this identification technique in several application areas. The standard system, therefore, provides the following inspection point types

Inspection points during the production process

The identifiers for the inspection points are defined in the task list header and are valid for all operations. If you do not define an inspection point identifier in the task list header, the system uses a general identifier, that is stored in the presettings at plant level.

Inspection points form the basis for defining partial lots with their own usage decisions. When used with control charts, inspection points are suitable for statistical process control.

If you define the use of inspection points in the task list header, you must specify whether the inspection points are to be based on time, quantity, or to be freely defined at the operation level. For inspection points based on time or quantity, you must also specify an inspection interval in the operation. During the production process, you create a data record that contains inspection results for each inspection point.

You must assign a produced quantity to each inspection point. You can combine the partial quantities for inspection points into partial lots and the partial lots into batches.

Inspection points to identify physical samples

The identifier for these inspection point types contains an additional field for recording the equipment number or functional location number.

Standard settings

Due to the summarization of data at the characteristic level, the maximum number of inspection points for each operation is limited in the standard system.

Recommendation

For performance reasons, retain the settings in the standard system.

Activities

1. Determine:
a) Whether your company carries out several inspections for an operation during production and how the inspection intervals are defined.
b) Whether you need special identifiers to record inspection results for physical samples. If the sample number meets your requirements, the standard entry should be sufficient.
c) Whether you need special identifiers to record inspection results for maintenance objects. If the sample number meets your requirements, the standard entry should be sufficient.
2. Define appropriate inspection point identifiers by assigning a suitable definition and sequence to the fields contained in the "Inspection Point Identifiers" table.
3. Specify default values for the usage decisions relating to the inspection points. To do this, refer to the steps contained in the subsection Inspection Completion. This describes how to define the quantity of usage decisions as well as the follow-up actions linked to the decisions. You assign follow-up actions for inspection points in production at partial lot level, and actions for other inspection points at lot level.
4. In view of the summarization of data at the characteristic level, determine whether the number of inspection points should be limited. If necessary, enter the maximum value accordingly.
5. Make sure appropriate
sampling procedures are maintained for the inspections carried out on the basis of inspection points. For additional information, refer to the chapter Quality Planning, Basic Data.
6. Check the presettings at the plant level and define default values for the:
