As technologists, our work is increasingly situated in highly complex socio-technical ecosystems. As much as we are encouraged to retrospectively seek a distinct and absolute root cause for an incident or outage, these complex systems are much more likely to drift into failure rather than suddenly taking one catastrophic wrong turn. What if you and your colleagues could measure the drifting safety boundaries of your systems? How would that inform the work you do? Join this session to explore these ideas through an introduction to the critical new discipline of continuous verification, the practice of measuring and monitoring the safety boundary of a system over time.
