Resilience Bites #9 - LinkedIn Rewind (week 14) is out!

I've discussed a few key concepts, including Sherlock Holmes' "Dogs Not Barking", the tension between high standards and adaptability, and why sometimes "turning it off and on again" contains hidden wisdom.

(7/n) I'm not saying teams shouldn't be responsible, but I am just wondering if our traditional ideas about accountability need to evolve as these systems become more autonomous.

(6/n) It's like trying to hold someone accountable for the weather. Yes, they can build the forecasting system, but at some point, the complexity makes understanding impossible.

(5/n) But here's my struggle. As these AI systems get more complex and their decision-making more opaque, can we honestly say the teams fully understand what's happening anymore?

(4/n) Your point about responsibility really got me thinking. While I love blameless postmortems too, the accountability question gets tricky with these systems. In theory, yes, the human teams should be responsible.

(3/n) And good catch on the redundant "famous" - definitely missed that one in editing!

(2/n) Yea, I should've been clearer about the difference between regular AIOps (where humans still make the final calls with AI help) and what I'm calling "meta-operators" (where the AI is actually making the decisions itself). Thanks for picking up on that while still following my main points!

When AI Makes the Call Questions About Meta-Operators and System Responsibility

🚀🚀🚀New blog post! 🚀🚀🚀

I have been thinking a lot about AI meta-operators, which are AI agents that will manage our systems and make operational decisions.

In this blog post, I am sharing some thoughts and asking questions.

I hope you enjoy it!

Chaos Engineering in the Age of AI: Surfacing Hidden Complexity The rise of AI in software development presents a fascinating paradox. While AI tools make it easier than ever to generate complex systems…

🚀 New blog post out! 🚀

This post discusses the 70% problem with AI-generated code, Bainbridge's automation ironies, and what chaos engineering can teach us about managing complexity in the age of AI.

I hope you enjoy it!

Happy weekend!

In every system, something works.

Rather than asking what's wrong and how to fix it, ask what's working and how to get more of it.

The best time to test your runbook is before the incident, not during it.

Right. The years and billions of dollars spent preparing are why Y2K didn’t “live up to the hype.” They *fixed* it. Before it happened. Which is good. Yes.
