And this is a truth about incidents: there are always more signals than there is attention available.

It’s so true.

Cool idea! When a process is overloaded, the system drops requests based on heuristics until the overload condition has passed.

It involves lots of machine learning and a “team resilience score”.

  Jennifer Riggins โ€” The New Stack

Every incident is unique, so incident analysis is about learning in order to improve resilience, rather than trying to “fix” a “root cause”.
