Goals of DevOps
Increase deployment frequency
Faster time to market
Shorten lead time between fixes
Faster mean time to recovery

Metrics of DevOps Number and frequency of software releases
Volume of defects
Time/cost per release
MTTR (Mean Time to Repair, Resolve or Resolution)
Number and frequency of outages / performance issues
Revenue/profit impact of outages / performance issues
Number and cost of resources
(Beal, 2014)

Typical Pain Points
Does communication affect collaboration?
Does QA have to wait for the provisioning of test environments?
Does committed code get bogged down in testing?
Do you have to revise committed code too often because it won’t run in the production environment?
Are your existing tools clumsy and not useful?

Choices of DevOps Tools
Choose tools that are easily integrated rather than silos of information and process.
Focus on Automation from End-to-End, empowering QA and Product Owners to Publish to (and Revert from) Production environments upon test acceptance (failure).
Open Source tools are mature, and APIs are prevalent.
