Besides the three directorates there are two staff departments. These departments support the management team as well as the primary process of the organization with frequent activities.

Strategic Advice Unit

The Strategic Advice Unit (ASA) supports the management and the primary process by providing advice. It acts as the initial point of contact for the primary process in which policy-related issues are concerned and is co-responsible for the development of implementation policies.   The unit maintains the administrative organisation and the DT&V's operational protocols.

Operational Management Unit

The Operational Management Unit provides various support services for the directorates. These include staff and organisation management, general and technical support, accommodation, procurement, communication and financial management. In addition, the unit is responsible for information provision, e.g. in case of parliamentary questions and requests for information from lawyers.
