Preliminary acceptance creates the basis for the execution of deployment measures as well as the subsequent launch of operation with acceptable risks.

Quality assurance measures such as tests and inspections are carried out in advance for preliminary acceptance. Preliminary acceptance gives users, developers, and operators the assurance that the transfer of the solution to the new state will most likely be successful.

Preliminary acceptance is planned early by all those involved. The acceptance criteria are agreed jointly in accordance with the deployment concept.
