A visual flow chart diagram that illustrates how two different but very related concepts can lead to system accidents 👌

• asynchronous evolution
• drift into failure

@prologic I don’t understand the diagram, nor have any idea of what’s about. 👌🏻

@bender allow me to try and explain over several Twts...

The idea of drift into failure is small normal adaptations erode safety over time without people noticing.

And the idea of asynchronous evolutions comes from system accidents where control failures emerge when system structure, constraints, and evolution are poorly managed.

Hmm. What can I say? 🧐🥴🫩 OK. 🤭😅😂

These ideas are dr the two books:

• Drift into Failure: From Hunting Broken Components to Understanding Complex Systems by Sidney Dekker (2011)
• Engineering a Safer World by Nancy Leveson (2011)

The former I haven't read. The later I haven't finished reading 😅
