A visual flow chart diagram that illustrates how two different but very related concepts can lead to system accidents 👌
- asynchronous evolution
- drift into failure

(#wuzfgia) @bender@twtxt.net allow me to try and explain over several Twts…
#5fy34za
(#wuzfgia) The idea of drift into failure is small normal adaptations erode safety over time without people noticing.
#6vlv5va
(#wuzfgia) And the idea of asynchronous evolutions comes from system accidents where control failures emerge when system structure, constraints, and evolution are poorly managed.

(#wuzfgia) 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 😅
