Hierarchy of inquiring systems in meta-modelling (Gigch & Pipino, 1986)

This concludes our little journey into constructivism, complex system thinking, and the big question: "What do we really really really know?"

System of Systems (Flood & Jackson, 1991) Decision making process (Simon, 1976)

Mittwoch, Januar 7th, 2009

Not really a summary of two article, but rather a summary of two constructivists‘ concepts.

Firstly, Flood and Jackson propose a System of Systems and point out the modelling approaches suitable for these specific systems:

  Unitary Pluralist Coercive
Simple Operation Research, Systems Analysis, Systems Engineering, System Dynamics Social Systems Design, Strategic Assumption Surfacing and Testing Critical Systems Heuristics
Complex Viable Systems Model, General Systems Theory, Socio-Technical Systems Thinking, Contingency Theory Interactive Planning, Soft Systems Methodology  

Secondly, because at some point in time I just had to write it down again, Simon’s constructivist process of decision-making, originally published in 1979:

Intelligence (Is vs. Ought situation) —> Design (Problem Solving) —> Choice —> Implementation —> Evaluation

With the extension of decision loops if no choice can be made as proposed by Le Moigne, revisiting the Design, Intelligence, or even the Initial step:

  • Re-Design – the How
  • Re-Finalisation – the What
  • Re-Justification – the Why
