  5. 5. VISI 20141126 JD slide 5 The key notion: organisation INF5890 Overview of theories on organizations and management Lars Groth 23 Every organized human activity - from the making of pots to the placing of a man on the moon - gives rise to two fundamental and opposing requirements: the division of labor into various tasks to be performed and the coordination of these tasks to accomplish the activity. Henry Mintzberg, The Structuring of Organizations, 1979
  6. 6. VISI 20141126 JD slide 6 It’s all about production and coordination … theories on organizations and management 24 Mintzberg’s division of labor is actually a division in actor roles: the ‘production units’ that bring about the (sub and end) products of the organisation. Production and coordination occur in universal patterns, called transactions. A transaction comprises 4 to 20 generic coordination steps regarding 1 specific production step. The operating principle of every organisation is that actors (subjects fulfilling actor roles), when performing coordination steps, enter into and comply with commitments regarding a production step.
  7. 7. VISI 20141126 JD slide 7 … and about (operational) structure INF5890 Overview of theories on organizations and management Lars Groth 23 Mintzberg says that the structure of an organisation is simply the sum total of the ways in which it divides its labor into distinct tasks and then achieves coordination among them. T1 T3 A1 T2 T5 T6 T4 A0 A2 A5 A6 A3 A7 T7 T8 A8 A4 We add to it that the structure consists of trees of building blocks which correspond with the structure of products.
  8. 8. VISI 20141126 JD slide 8 By virtue of the building block concept, and by abstracting from information systems and implementation technology (including ICT), a reduction of complexity of more than 95% is achieved! flow charts notes narratives interviews essential model What does DEMO offer you? The resulting essential model offers the intellectual manageability you need: insight in and overview over the most complex tasks!

  11. 11. VISI 20141126 JD slide 11 PRODUCTION WORLD COORDINATION WORLD production acts coordination acts coordination facts production facts It is all about production and coordination … interacting subjects The interacting subjects perform coordination acts and production acts, resulting in coordination facts and production facts, in response to coordination events (the coming into being of coordination facts).
  12. 12. VISI 20141126 JD slide 12 Alicia: I’d like to have a bouquet of red tulips Alicia : request : Celestine : sales #31416 is completed Celestine: Just a moment Celestine : promise : Alicia : sales #31416 is completed Celestine: Here you are Celestine : state : Alicia : sales #31416 is completed Alicia: Thanks Alicia : accept : Celestine : sales #31416 is completed Examples of coordination acts
  13. 13. VISI 20141126 JD slide 13 Validity claims in coordination acts Claim to justice (G: Richtigkeit, NL: juistheid) Has the performer the authority to perform the coordination act? Claim to sincerity (G: Wahrhaftigkeit, NL: oprechtheid) Is the performer sincere in performing the coordination act? Claim to truth (G: Wahrheit, NL: waarheid) Does the product exist or can it be produced? Ultimately, the performer of a coordination act is autonomous. He/she is however always responsible and accountable for his/her acts.

VISI 20141126 JD slide 23 request promise accept state A0 T1 A1 An actor A0 (the initiator of T1) comes to agreement with an actor A1 (the executor of T1) about the delivery of a product P1. Basically, A0 doesn’t need to care about what A1 has to do in order to produce P1. At some point in time, A1 addresses A0 and performs the state act in the transaction T1. Business process (1)

  29. 29. VISI 20141126 JD slide 29 DEMO and BIM (1) Henk Schaap, 24 april 2013 Het BIM is niet alleen een bron om te raadplegen, het is ook een data bank waarin je verandert! Want elk feit is het resultaat van een transactie (of het is berekend)!
  30. 30. VISI 20141126 JD slide 30 Building Information Modeling (BIM) is a digital representation of physical and functional characteristics of a facility. A BIM is a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle, defined as existing from earliest conception to demolition. (National BIM standard USA) DEMO and BIM (2) The BIM models in a building project could very well be used as the Fact Model in DEMO. What has to be added are the transaction results, i.e. the completion of the various parts of the project.
  31. 31. Conclusies en vragen
  32. 32. VISI 20141126 JD slide 32 Het denken in transacties en actorrollen is perfect overgenomen in VISI Het DEMO-1 transactiepatroon in VISI zou vervangen moeten worden door het DEMO-3 transactiepatroon. Aan het denken in processen (boomstructuren van transacties) binnen VISI zou de ‘roll back’ in een keten van transacties toegevoegd moeten worden. Een combinatie van DEMO en BIM lijkt heel goed mogelijk. Het belangrijkste inzicht is dat BIM ‘er niet gewoon is’ maar gemaakt wordt in transacties. DEMO in VISI: conclusies en vragen
