Figure 21: Process module Quality Assurance


The »Process Module Quality Assurance (QA) defines the basic processes for planning and executing quality assurance measures. It describes how and by which means the project quality is intended to be ensured (QA Manual). In addition, products and activities of this process module are used for


Test activities are included in the corresponding process modules (system development, software development, hardware development). If the project does not include the respective development activities, test activities are not required.

In contrast to the development tests, all formal tests shall be executed by an independent »Inspector (e.g. developer colleague). In addition, they must be repeatable (evaluation specification, evaluation procedure, evaluation report). The rule that the producer shall not test his/her own product (four-eyes principle) applies to all formal tests.

The regulations of the process module Quality Assurance (QA) shall in no way affect organizational specifications, i.e., quality assurance tasks need not be executed in one organizational unit, but can be executed within the scope of the development - however, the four-eyes principle must always be ensured.

Product States in Tests

If quality assurance measures are not planned for specific system products (system components, software, hardware), these products proceed from the state "in processing" to the state "finished" after the development tests have been completed.

Products which are intended to undergo quality assurance measures proceed at first to the state "submitted". After the tests have been completed successfully, they from the state "submitted" to the state "finished".
