QM specifications

You can use the QM Specification module to create, maintain, and remove quality management specifications.

When you open the QM Specification Definition workspace tab, the QM specifications (optionally filtered) are shown.

By default, the QM Specification module is in the Quality Management group in the Navigation Bar. For more information on groups and modules, see Groups and modules.

A QM specification is the specification for Statistical Process Control (SPC) analysis of various characteristics linked to it. It also specifies the way sampling has to be carried out for each of the linked characteristics.

The context data of a QM specification decides how a linked characteristic is going to be measured during run time. For example, a characteristic, such as temperature can be measured in various contexts like item, entity or operation. This means different samples have to be taken for different contexts for the same characteristic. A QM specification may have the combination of the contexts mentioned above that specifies how the samples are to be collected.

You can configure QM specifications associated to variables and attributes. You can modify QM specifications that are currently effective, and also those that are no longer effective.

You can delete a QM specification from the database. An error message appears if you delete a QM specification that is currently effective. An error message also appears if there is a sample or characteristic linked to the QM specification. This message shows the number of sample/characteristic combinations that are assigned to the QM specification. If both the error messages appear, they are combined into a single message. The error message allows you to delete the QM specification. For more information on deleting, see Delete an object.

An error message appears if the QM specification cannot be saved. Modify the QM specification, as needed, to correct the error and save to clear the error.
