Main tasks

The validation takes place in the form of analysis and tests with (sub-) system and systems. Validation includes checking the requirements for correctness focused on planning, conducting and documenting the validation according to the responsibilities.

Authorities

• If a requirement includes achieving a probability value (e.g. reliability, safety), validation is performed by checking retraceable reasons and calculations.
• Due to the independence conditions (The double-check principle (by two people independently) of quality assurance applies.) the following possibilities are recommended for checking:
• double check with another validator, or review within the project; in this case, the review minutes specify that the implementation of findings lies in the validator's scope of competence and is not influenced by the project team (only for SIL > Basic Integrity)
• This means that independence is ensured. In projects in which more than one organization and country are involved, the validator of the lead project additionally coordinates all units.
