The document discusses quality engineering (QE) and its role in a DevOps transformation at Salesforce. QE is involved at all stages of development to prevent issues. They work closely with developers, operations, security and other teams. The goal is to build quality into the product from the start and make quality everyone's responsibility, not just testing. A DevOps culture with strong QE collaboration can deliver high quality services to customers.

Editor's Notes
- #4: more than 15K employees, graph (by FY) doesn’t even show it but already 2+ bb/day, yikes!
- #5: From the folks in engineering, to the people in design, from the factory to the showroom, to the people on the line!
- #6: lower MTTR! shorter lead time! easier deployments! been a DevOps ambassador
- #7: Gary Larsen Far Side
- #8: What QE hears, talk about ISD and Conor/Alan, customer focused quality mindset
- #10: Quality Engineering is about improving the output as well as the processes that generate the output. Output can be Code, H/W, Design, etc. Gene Kim’s 1st way
- #11: Network of Guardian Angels keeping a watch of all aspects Technology : Software, Infrastructure Research: Ask questions to get more information to ask more questions; Proving and disproving theories
- #12: Fits in with CAMS model Risk Analysis - Planning, Reviews Validation - Exploratory Testing, Blitz, Pairs Testing, Test Automation, Test Envs Tools Strategy - CI, Test Frameworks Production Validation Strategy - Post Release Monitoring, Canary Release, Staggered Releases, Destructive Testing
- #13: Customers don’t care whether it is a Software or Infrastructure issue as long as the service is up. How can QE partner with everyone to make this possible? Here are a few examples…..
- #14: Dave:
- #16: Test the Design Find bugs even before code is written, dependencies, impact Continuous Integration
- #17: Help with Functional Testing
- #18: What details can we provide for Puppet in a Box? Combine with previous slide Has spawned other In a box (Ajna)
- #19: Dave: This has been extended into ftests on Jenkins, acl testing, hbase, etc.
- #20: Someone else is going to have to carry a pager too! (sign me up for this one)
- #21: Ha ha - talk about 1st DevOps internal mini-conf
- #22: Reena: Plans: Validation, Implementation, Rollback or Roll Forward QE knows how to break the system Ops knows how system will fail Embrace Failure; Build Resiliency into the system
- #23: Dave: Just talk about as a generic service, nothing specific Unknown what it was before testing, only estimates Gene Kim’s 3rd way also seeing more “days of green”, more signal/less noise
- #24: We’re going to need to give all the Devs access to Production!
- #25: virtual appliances, what did security do with this? Taher quote
- #26: Build Security In just like Build Quality In Build a group of QE Security Experts Incorporate Security Testing tools into CI Need to have a hacker mentality compared to being a customer advocate
- #27: Dave: “I for one welcome our new robot overlords”
- #28: less time on features, more time on fixing bugs Service Ownership - Service Delivery Playbook
- #29: Dave then Reena: Quality isn’t just QE’s responsibility. Service Ownership.
- #30: They don’t care whether it is a Software or Infrastructure issue as long as the service is up. Achieves goal of QE to represent the customer Rapid delivery of high quality software is a goal shared with DevOps DevOps 3 Ways: System, Feedback Loops, Iterations
- #31: need Culture (quality mindset) more than tools
- #32: need Culture (quality mindset) more than tools
