5. Systems
Thinking

6. Semantics and Dynamics
Desired-state and actual behaviour
Dev + Ops
What you intend + What actually happens

7. IT would be easy if systems were deterministic ...
Dev ?
Ops ?

8. LOGIC rains environmental complexity ...

9. Autonomous
“Continuous delivery requires continuous automation
infrastructure

10. There is no such thing as an immutable system
No intended change is not the same as no change at all

11. “Many worlds” branches and relativity

12. Failures are semantic
Processes are
dynamic
“The history of attempts to prevent cracks from spreading or evade
their consequences is almost the history of engineering.”
-- J.E. Gordon The New Science of Strong Materials
