Analyses and field notes from an intervention CTO on complex systems.
Every component works. Yet the system fails.
Several perfectly compliant sub-systems can together produce non-compliant behaviour: some properties emerge from the interactions.
A working PoC doesn't prove you have a product
A proof of concept reduces one specific uncertainty. It proves neither the robustness, nor the reproducibility, nor the manufacturability of a product.
The problem isn't always where you're told to look
When every component is compliant but the system misbehaves, the cause often lies in their interactions, not in any single part.
