DEMO (Design and Engineering Methodology for Organisations) is the leading methodology in the new discipline of Enterprise Engineering (EE)1. In DEMO, an organisation is primarily considered as a purposefully designed system. Changing the organisation thus means re-designing and subsequently re-engineering it. Only in this way can unity and integration be achieved and maintained.
The philosophy of DEMO is that people are the ‘pearls’ of every organisation. Equipped with the right authority and acting from the corresponding responsibility, these people bring about the services they deliver to each other, in social interaction. The philosophy therewith encourages sense making and collaboration.
The theory of DEMO is that this social interaction takes place in universal patterns, called transactions. Business processes are clear tree structures of transactions, not mind-boggling railroad yards. ICT applications are supporting tools for people, they do not take over responsibility. The essence of every organisation is that it consists
of a network of transactions and actor roles, independent of any implementation.
This essence is captured in four integrated models: the Construction Model (actor roles and transactions), the Process Model (business events and business processes), the Fact Model (business objects and business facts) and the Action Model (business rules and work instructions). Because the models are formalised, ICT applications can directly be generated from them, and the dynamic behavior of the organisation can be studied through simulation.


  • Unequaled reduction of complexity
  • Broad overview and deep insight in your operations
  • Transparency of responsibilities and interactions
  • Clear identification of process and data ownership
  • Comprehensive, coherent, consistent and yet concise models
  • Employees become the pearls of your organisation
  • Keeping control over the most complicated changes


  • Application portfolio analysis based on the essential model (Rijkswaterstaat 2007)
  • Unique survey of and insight in post merger integration (Air France/KLM 2010)
  • New energy from connecting management and shop floor (Marechaussee 2011)


First, you will appreciate the paradigm shift in thinking about organisation, business processes, information systems and ICT that the underlying theories of DEMO offer.This paradigm shift is known as Enterprise Ontology, a new notion that you will learn thoroughly. On the basis of small exercises and examples from practice, you will appreciate that the Enterprise Ontology based essential model is comprehensive, coherent, consistent and yet concise, and that it captures the essence of an organisation, independent of realisation and implementation.
Next, you will learn to produce, to verify and to validate two of the four aspect models, namely the Construction Model and the Process Model, while applying the so-called OER-method (Organisational Essence Revelation) to rather well-described cases. In addition you will discover that DEMO can be viewed as complementary to familiar approaches: organisational approaches (Balanced Score Card, Lean & Six Sigma, etc.), BPM approaches (BPMN, EPC, PetriNet, Archimate, etc.), and IS development approaches (ER, NIAM, ORM, etc.). What DEMO adds to them is theoretical
foundation, so that you thoroughly understand their mutual connections.
Lastly, you will be introduced to the discipline of Enterprise Engineering, which is built on Enterprise Architecture, Enterprise Governance and Enterprise Design, next to Enterprise Ontology.


The DEMO Bachelor course (download as PDF) is intended for practitioners in the field of organisation and ICT (like enterprise architects / consultants, business architects / analysts / consultants, information managers, business process managers, and quality managers) who want to be educated more profoundly in their field of practice, and who particularly look for a solid methodological foundation of their profession.


Therefore, the contact days are normally spread over three weeks. There are no prerequisites for enrolling in a DEMO Bachelor course. Everyone with common sense and an open mind (and with some experience in organisations) is able to attend the course successfully.
Next to (digital) handouts, the DEMO Basis (published and sold by Sapio Enterprise Engineering) is used as course material; it consists of:
• Jan L.G. Dietz: Red garden gnomes don’t exist
• Alicia P.C. Perinforma: The essence of organisation
• Jan L.G. Dietz: Glossary of terms

The Enterprise Engineering Institute regularly (about 3-4 times per year) organises written exam sessions. They can also be taken at distance. If you pass the exam, you receive the DEMO Bachelor diploma and you will be recorded in the register of Certified DEMO Bachelors.
