- 21. What is a System?
- 22. What is a System? • A network of interdependent components that work together to accomplish the aim of the system • A system must have an aim Without an aim, there is no system W.E. Deming, The New Economics 1993
- 23. What is a System? • A set or pattern of relationships that work together in some fashion. Systems can accomplish things that would be impossible if the same elements were put into random relationships, or none at all… Dr. Bill Bellows, 2010
- 24. What is a System Thinking? • A way of looking at the world: –Relationships over Unrelated Objects –Connectedness over Isolated Events –Process over Structure –Patterns over Contents –“WE” over “ME”
- 25. What defines a System? • Definable Aim or Purpose • Boundaries • Many Parts • Inputs/Outputs • Feedbacks • Emergent Properties
- 26. Each Part in a System… • Has its own purpose • Is interdependent • Interacts with others
- 27. We Cannot Understand a System… • By looking at a collection of its parts • Without looking outside of it for why it exists • By analyzing it (taking it apart)
- 28. Systems are... • Indivisible • A product of its interactions, not the sum of its parts

- 33. Ball Point Game • What have we put in place that can be considered anti-systemic? • Did the improvement your team came up with at the end of the first round address the system or a part of the system? • What improvement would you make to the game, thinking about your whole system?

Notes de l'éditeur
- Starting with the team…
- Management by Objective: We introduce a bias early on to challenge you to achieve a goal Constraint: The person who starts is also the person who must touch it at the end. Creates a bottleneck Transportation: Why can’t we pass the balls to the person beside us? Motion: Why do we need to move the ball from one hand to another? Overproduction: What is the customer demand for these in the first place? Waiting: For the queue to fill; can we collapse the number of touch points? Fit for Purpose: Does the product even meet the customer’s needs? Why are we producing this in the first place?

- Next Meetup: Thursday, April 26th at 6pm
- The product of analysis is how things work, never, why they work the way they do. Explanations always lie outside the system, never inside
