Current enterprise information systems, notably ERP-systems, are rarely a big success. The main cause of the many failures in practice is the prevailing wrong understanding of these systems.
The prominent current idea is that an enterprise information system (EIS) is a product, like for example a car or a house, that can basically at will be replaced by another one.
This way of thinking is, however, fun-damentally wrong. The proper metaphor for an EIS is the nervous system of a human body.
Like the nervous system is intrinsically and intensely connected to the body it supports, an EIS is (or should be) intrinsically and intensely connected to the organisation that it serves.
Consequently, like a neurologic surgeon needs appropriate and thorough knowledge of both the nervous system and the human body, an EIS designer not only needs thorough knowledge of information systems.
He or she needs also, and particularly, appropriate and thorough knowledge of organisations. Contemporary designers and implementers of ERP-systems lack such knowledge.
In this tutorial you will learn what this proper and deep knowledge of organisations is about.
You will adopt and appreciate a revolutionary new way of understanding and revealing the deep patterns of operation in organisations; patterns that are fully ignored in current business process models.
It is all based on a well-founded and proven theory about organisations, the PSI-theory (Performance in Social Interaction)1.
A more common term for referring to this way of understanding organisations, in which one completely abstracts from realisation and implementation, in order to reveal the essence of the organisation, is "Enterprise Ontology".
Enterprise Ontology is one of the four pillars of the discipline of Enterprise Engineering2.
Recently, an easy introduction to Enterprise Ontology, as well as to the pioneer Enterprise Engineering methodology, called DEMO (Design and Engineering Methodology for Organizations), has been published3.
The PSI-theory states that people are the 'gems' of every organisation.
Equipped with the right authority and acting from the corresponding responsibility, they bring about, in social interaction, the services that they deliver to the environment, and to each other.
This social interaction takes place in universal patterns, called transactions.
The essential model of an organisation is a network of transactions and actors, divided in three sub networks, called aspect organisations: the B-organisation (B from business), the I-organisation (I from information), and the D-organisation (D from documental).
In the B-organisation, the business transactions take place, resulting in the delivery of business services to the environment. The I-organisation delivers informational services to the B-organisation, like remembering, sharing, and deriving information.
The D-organisation delivers documental services to the I-organisation, like archiving and providing documents (which contain the information that the I-organisation deals with).
This tutorial focuses on the application of the PSI-theory to the design of enterprise information systems (EISs).
The insightful new way of understanding EISs clarifies at once why standard EISs, like ERP systems, are rarely a big success.
The knowledge you acquire puts you back in the driver's seat when having discussions with EIS/ERP-systems suppliers.
