Three Learning-ConversationsThree Learning-Conversations•Why ? are we learning these
techniques and tools now?•What ? are the processes
involved here, now ?•HOW ? can we learn these better
together?

The Why? conversationThe Why? conversation• What are the Aspirations &
Expectations & anxieties and time commitments of the participants?
• How we can actually collaboratively handle all by using these systemic modelling techniques and tools.
• Why study these processes in this order? (alternating top-down & bottom-up)

The HOW-TO LEARN/BUILD, CONVERSATIONThe HOW-TO LEARN/BUILD, CONVERSATION
• Start with stories about what is seen as a problem in a focal system.
• GO through the Basic Cybersystemic modelling questions (see next slides).
• Sketch a processes-relationship with the context systems graph –discuss opportunities & constraints.
• Sketch a schema for the processes , conditions, actions and objects in the focal system- discuss
• Choose the model- type or types needed ? (automata, Game, Dynamic system,?)

CYBERSYSTEMIC MODELLING CYBERSYSTEMIC MODELLING INITIAL PHASESINITIAL PHASES
• PHASE1:- From source systems identify (space, time, goals) FOCAL system ?
• Phase2.Map relations/loops between context systems and focal system?
• Phase 3 Model Focal system as an hetrarchy of ? games and production systems?

e.g. Phase 2 Context system Questionse.g. Phase 2 Context system Questions
• Q1 – What are the main good (control Variety) and BAD (disturbance Variety) inputs your F/S gets from context systems?
• Q2 What are your F/S main Good and Bad outputs to context systems?
• Q3 What Feedback (-&+) loops from your outputs back to your inputs exist in the context systems?
• What are the time delays and attenuations in each loop?

Similar modelling questions are Similar modelling questions are used to construct the schemas used to construct the schemas for all subsequent modelling for all subsequent modelling

The Central Question is how The Central Question is how can control variety be made to can control variety be made to exceed disturbance Variety?exceed disturbance Variety?

Formalize & ComputerizeFormalize & Computerize• Choose the most appropriate formal
representation(s) ?• A game-drama storyboard?• the Dynamic Stack & Flow system
notation (of Stella™, Dynamo™ etc.)or• Put the schemas in Context+™ Maps
(Jaworski et al.) & convert to Java etc.

Challenges we have found:-Challenges we have found:-• Surface-learning aims –e.g. mash-up
existing stuff to make X look good.• Mere tool-options mastery focus• Context ignore-ance• Hetrarchical Dynamic Process
schema conceptualisation• How to merge/join knowledge from
different sources?• Ad-hoc myopic granularity focus• Too little Quality-Attention-Time

BASIC QuestionsBASIC Questions• How much value do the stakeholders
place on this work?• What level of causal validity and
reliability and fidelity of model/simulation/application performance is therefore justified?
• Are the available people and tools capable of achieving this in time?
