Under the lead of Stol Consult many information systems have been developed for public and private organisations, always "under architecture". The emphasis has been on control and administrative systems (Personal and Organisation, Finance, Planning, Logistics, etc.). Examples are:
- Complete administrative and control system for Direction of RWS (DVK).
- Various information systems of Statistics Netherland (e.g. Labour Force survey, Business Register, Administrative systems).
- Technical University of Delft: administrative and control informationsystems.
- Electronic datacapture systems for government.
