THE FEEDBACK LOOP

POST DEPLOYMENT VERIFICATION
• Ensuring what we’ve deployed is actually working
• Allows quick pickup of defects in production
• We use the atlassian-healthcheck plugin for this
![Page 40: Delivering New Features to Over 30,000 Customers — Daily](https://reader034.vdocuments.us/reader034/viewer/2022051323/54b732a14a79595e468b4584/html5/thumbnails/40.jpg)
INFRASTRUCTURE ANALYTICS
• A deeper level of feedback for our operations and infrastructure teams
• Check CPU time, IO, JVM statistics, power usage
• Helps us diagnose platform related usage and problems
![Page 41: Delivering New Features to Over 30,000 Customers — Daily](https://reader034.vdocuments.us/reader034/viewer/2022051323/54b732a14a79595e468b4584/html5/thumbnails/41.jpg)
PRODUCT ANALYTICS
• Statistics of new feature discovery and usage
• Consumed by product and plugin teams, and their product managers
• Helps us experiment and A/B test new features in production
![Page 42: Delivering New Features to Over 30,000 Customers — Daily](https://reader034.vdocuments.us/reader034/viewer/2022051323/54b732a14a79595e468b4584/html5/thumbnails/42.jpg)
BUG REPORTS & SUPPORT CASES
• The last resort - we want to minimize this kind of feedback
• If an issue slips through to production, and is not picked up by our automated checking it will generally result in a support case
![Page 43: Delivering New Features to Over 30,000 Customers — Daily](https://reader034.vdocuments.us/reader034/viewer/2022051323/54b732a14a79595e468b4584/html5/thumbnails/43.jpg)
• These four types of feedback are all critical in pushing information back to the developers and PMs
• Closes the delivery loop• An awesome delivery pipeline
is next to useless if you can’t see what’s going on
![Page 44: Delivering New Features to Over 30,000 Customers — Daily](https://reader034.vdocuments.us/reader034/viewer/2022051323/54b732a14a79595e468b4584/html5/thumbnails/44.jpg)
