Quality Management (QM) 

Use

You can enter data for a quality control to accompany a process. Every stage and operation in a general or site recipe can be relevant to Quality Management.

Integration

The system transfers the planned inspection elements and some of their attributes (inspection characteristics, inspection methods, and sampling procedures) to the master recipe when you transform a general or site recipe to a master recipe. The QM data at operation level in the general or site recipe is transformed to phases; the QM data at stage level is transformed to operations.

For more information, see Transformation Process.

Prerequisites

·        You have created inspection characteristics, inspection methods, and sampling procedures. (Logistics ® Quality Management ® Quality Planning ® Basic Data ® Inspection Characteristic, Inspection Method or Sample)

·        You have specified the plant that is responsible for the master inspection characteristics and inspection methods for your corporate group (see Customizing for Recipe Management under Specify Environment Parameters).

·        The formula for which you want to enter QM data contains a stream as the output.

We recommend that you also make the following settings:

·        You have created the weightings of the characteristics (see Customizing for Quality Management under Define Characteristic Weighting).

·        You have set up the priorities of the characteristic weightings (see Customizing for Recipe Management under Characteristic Weighting Settings).

Activities

·        You enter your data in stage and operation editing in the  QM formula view on the  Formula tab page.

·        You use the reference type to specify a reference for the frequency of the inspection (for example, time or quantity), and then specify the inspection interval in terms of time or quantity produced.

·        Choose the required master inspection characteristics in the inspection table. If inspection methods are assigned to the master inspection characteristics, they appear automatically in the input help for the relevant column. Each row containing a valid master inspection characteristic represents an inspection. You can add sample quantity and sample unit of measure data to each inspection.

·        If the Sample indicator has been set in the properties of the current master inspection characteristic, you can select a sampling procedure.

If you set the Copy Model (Use Inspection Char. as Copy Model) indicator, you partially remove the reference to the master inspection characteristics (see Master Inspection Characteristics As a Copy Model or Reference). This means that the system takes the relevant attribute values for this inspection from the corresponding data record of the current recipe rather than from the master inspection characteristic when it transfers them to the master recipe.

·        If you use the master inspection characteristic as a copy model, enter the required values for all the relevant inspection characteristic attributes (for example, characteristic weighting, target value, and tolerances).

·        You can store details for each inspection characteristic in the form of texts in the bottom part of the screen. If you have not selected a sampling method, you can enter details for the sampling type, sample size/sample percentage, and individual inspection frequency here. To do so, double-click the inspection characteristic in the table.

You use the individual inspection frequency to specify the frequency with which a physical-sample drawing is to take place.
