#SRE

This article says it's about #SLOs, but it's really about measuring #latency. Gil Tene (CTO of Azul, the high performance JVM company), has a bunch of talks about this, which he calls “coordinated omission.” If you search for Gil and that term, you'll find lots of talks and posts about it.

#SRE Report 2023

The report contains special contributions from Adrian Cockcroft and Steve McGhee and highlights findings from a global community of reliability practitioners, including SREs, managers, architects, and executives

Key findings include:

* Organizations who operate with a “just culture” are 500% more likely to be Elite performing organisations

* Elite-performing organizations are 260% more likely to substantially focus on Customer Experience reliability versus Low-performing organisations

* Organizations (59%) say that maintaining innovation velocity occasionally or often impacts employee productivity or morale – 14% unsure

* Organizations (59%) say tool sprawl is a non-existent or minor problem – challenges other research which simply equates tool sprawl to, ‘how many tools are in the stack’
