Summary
SREs attain advanced stability levels by actively learning from system problems that are within their scope of responsibility and from purposely induced disruptions. SREs can gain wisdom through the wheel-of-misfortune practice that adopts a gamification approach. Chaos engineering is the ultimate testing method for mature systems where all other tests have not revealed deficiencies.
At this point, you should be able to conduct a wheel-of-misfortune game implementation in your organization and guide SREs on continually learning from the most noteworthy incidents. Capture the precious lessons learned from blameless postmortems and retroactively feed them into the knowledge base so the team can respond quicker in future similar scenarios. Remember to make all of those efforts a fun game.
By now, you understand why chaos engineering works and how you can apply it to systems to unveil hidden faults.
In the next chapter, we will coach you for an SRE job interview and discuss...
