8 JAN L.G. DIETZ RED GARDEN GNOMES DON T EXIST ON THE ESSENCE OF ORGANISATION AND THE ROLE OF ICT

9 Red garden gnomes don t exist Prolog This insight is nothing less than a paradigm shift; you must be willing to grasp and adopt it. The price is that you have to throw off your current way of thinking about organisation and ICT. The reward will be a proper understanding of the prospects and limitations of ICT for humans, organisations, and society at large, so that you will no longer feel uncomfortable with nonsensic horror stories about robots and other artifici intelligent things that would take power over us. What has l this serious stuff to do with garden gnomes That is a secret that will be unveiled while reading the book. You will discover that modern societies are crawling with blue and green garden gnomes, to the benefit of l of us. You must only look out for red garden gnomes because they cannot exist Rijswijk, 9 October 2014 Prof.dr.ing. J.B.F.

10 The paradigm shift in astronomy The origin meaning of paradigm is: example for explanation. Graduly, this meaning has been expanded to: core view of a theory. The heliocentric view of Copernicus (1543) The geocentric view of Ptolemy (150) Sun Earth Mars 10

11 The importance of a good theory There is nothing so practic as a good theory (Kurt Lewin) Whether you can obsee a thing or not depends on the theory that you use. It is the theory that decides what can be obseed (Albert Einstein) Theories are the ment glasses through which you perceive the world and conceive your understanding of it. 11

12 The application-centric view (1975) The task of the ICT-profession is to develop a system (application) on the side, and to implant it, once it is completed The development process is roughly: requirements determination, function design, technic design, implementation The function requirements are determined basicly by inteiewing the customer and the future users The focus is on processes, data, and ICT opportunities The delivered system rarely meets the re function requirements (expectations). In other words, requirements determination mostly fails Standardisation, like in ERP-systems, hardly solves the requirements determination problem. Instead, it puts the users in armours 12

13 The organisation-centric view (2005) The task of the ICT-profession is to develop and instl a new implementation of (a part of) the organisation The development process is roughly: produce ontologic model, devise new implementation model The function requirements are fully determined by the ontologic model of the organisation The focus is on human cooperation, and on authority and responsibility In addition, the organisation may itself be subject to redesign. This comes down to devising a new ontologic model, by an enterprise engineer (!) Because the ontologic model is fully formisable, automatic generation of the new implementation is a reistic option 13

16 PSI: Peormance in Soci Interaction The operating principle of organisations is that subjects (human beings) enter into and comply with commitments, which are raised in coordination acts. The result of an act is a fact. Coordination acts/facts regard a product (= independent production fact plus dependent production facts). They occur in interaction patterns, cled transactions, between two actors. One has the role of, the other the role of. The construction of an organisation consists of actor roles and transaction kinds. An actor role constitutes the authority to be in transactions of a particular transaction kind. An organisation is made operation by assigning actor roles to subjects on the basis of competence. The resulting actors are assumed to exercise their authority with responsibility. 16

17 The transaction process In the order phase, the and discuss the product to be produced, and try to agree Order phase Asking for transport Ordering a book Applying for membership In the execution phase, the produces a product Execution phase transaction process In the result phase, the and discuss the product that has been produced, and try to agree Result phase Being transported Having got the book Having become member 17

It may be an role in 0, 1 or more transaction kinds. An actor is a subject fulfilling an actor role. A subject may fulfill sever actor roles (sequentily or simultaneously), and an actor role may be fulfilled by sever subjects (sequentily or simultaneously or collectively). 40

41 The organisation building block (2) A0 request promise T1 accept state A1 A0 (the of T1) comes to agreement with A1 (the of T1) about the delivery of a product P1. A0 does not care and need not care about what A1 has to do in order to bring about P1. At some point in time, A1 addresses A0 and peorms the state act in the transaction T1. 41

42 Organisation construction and process A0 request promise T1 accept state A1 T2 T3 T4 A2 A3 A4 T5 T6 T7 T8 A5 A6 A7 A8 In order to produce P1, A1 needs a P2, a P3 and a P4. And NOTE: component transactions may so be carried out in parlel. 42

48 Conclusions of lecture 1 There is a paradigm shift going on: from and application-centric to an organisation-centric view on ICT activities According to the PSI theory, l activities in l organisations can be understood as (atomic) steps in transactions The complete transaction pattern is univers The construction of an organisation consists of tree structures of basic building blocks In the PSI theory, people are the pearls of the organisation. Based on their competence, they get authority, which they are assumed to practise with responsibility 48
