Dr. Sjir Nijssen is CTO at PNA in the Netherlands (www.PNA-Group.nl). Dr. Nijssen started with fact based business modeling in the early seventies, at Control Data’s European headquarters in Brussels. Since then it has been more than his full-time occupation. It was there where NIAM (Natural language Information Analysis Method), a fact based business practice and notation, was conceived. After holding a position as professor of Computer Science for seven years, he founded the company PNA in 1989, exclusively dedicated to delivering business requirements, consulting and educational services fully based on fact orientation. PNA currently employs over 50 people. PNA has been awarded the first accreditation in the Netherlands for a bachelor curriculum entirely based on extended fact orientation, in which all subjects are delivered in fact orientation knowledge format (including fully describing concept definitions, fact types, fact type readings and rules).
