- 6. “To support our users in establishing their own Resilience Engineering Capability”
- 8. And why are we scared of it?
- 9. “not correct or true; incorrect.”
- 10. “an injurious, unfair, or unjust act”…
- 11. …“action or conduct inflicting harm without due provocation or just cause”

- 18. Why is wrong scary?
- 19. Risk?
- 20. Consequences.
- 21. Why us?!
- 22. Two factors
- 23. Feature Velocity
- 25. Feature Velocity VS. Reliability
- 26. Good news!
- 27. No conflict!
- 28. Feature Velocity VS. Reliability
- 29. Feature Velocity + Reliability
- 35. What about tests? gates? pipelines? isolation?
- 36. We’re covered…
- 37. A Story…
- 41. And it gets worse…
- 42. Dark Debt…
- 44. And over to the business…
- 45. “One Hour of Downtime Costs > $100K For 95% of Enterprises” http://itic-corp.com/blog/2013/07/one-hour-of-downtime-costs-100k-for-95-of-enterprises/
- 46. “lost revenue and lost end user productivity" http://itic-corp.com/blog/2013/07/one-hour-of-downtime-costs-100k-for-95-of-enterprises/
- 47. “not take into account the cost of additional penalties for regulatory non-compliance or “good will” gestures made to the organization’s customers and business partners that were negatively impacted by a system or network failure. In fact, these two conditions can cause downtime costs to skyrocket even further” http://itic-corp.com/blog/2013/07/one-hour-of-downtime-costs-100k-for-95-of-enterprises/
- 48. Bad news…
- 50. Microservices-based systems tend to look like…

- 52. “The rate of change is high; the systems change before a full description (and therefore understanding) can be completed.” John Allspaw: https://queue.acm.org/detail.cfm?id=2353017
- 53. “How components function is partly unknown, as they resonate with each other across varying conditions.” John Allspaw: https://queue.acm.org/detail.cfm?id=2353017
- 54. “Processes are heterogeneous and possibly irregular.” John Allspaw: https://queue.acm.org/detail.cfm?id=2353017
- 55. Reactions?
- 57. Blame.

- 63. Zero Blame
- 64. Go Beyond Blame
- 67. “prepare for undesirable circumstances” - John Allspaw
- 68. Deliberately Practice Being Wrong = Chaos Engineering
- 70. Resilience is a Learning Loop
- 71. “Normal”
- 72. Outage “Normal”
- 76. “Never Let an Outage Go To Waste” - Casey Rosenthal
- 77. Post-mortem Learning is Good
- 78. Pre-mortem Learning is Better!
- 79. “Chaos Engineering is the discipline of experimenting on a distributed system in order to build confidence in the system’s capability to withstand turbulent conditions in production.” - principlesofchaos.org

- 85. We can learn after outages… but it’s even better to learn from weaknesses before an outage.
- 86. Being Wrong can be a super power, if it leads to learning
- 87. Establish a Platform for Pre-mortem, Deliberate Practice “Being Wrong”
