Rapidly evolving business demands and competitive environments pose challenges to increase the speed of delivery and do better with less. This often results in sacrificing quality and failing to understand that a minimum viable product must be “viable” to the customer. When organizations realize this, they often turn to DevOps practices that are rapidly becoming the new norm. Gajan Pathmanathan discusses how to ensure quality-driven development through DevOps while maintaining delivery speed. He focuses on the transition an organization needs to make to ship “quality” software frequently, the importance of an efficient testing feedback mechanism, and some infamous fallouts if quality is overlooked. He explores a spectrum of tools—Docker, Bamboo, Jenkins, Selenium, Cucumber, and Splunk—that can be used to enable continuous quality throughout the software delivery pipeline. Join Gajan to discuss the need for quality-driven development in an agile environment. Take away ideas to optimize the value stream and ensure continuous quality by implementing DevOps.

Why DevOps & QDD?

14. When I change one line of code…

17. Why These Happen?
#ShitHappens
Lack of:
○ testing (duh!)
○ collective ownership and accountability
○ predictability and auditability

18. So Why
DevOps & QDD?
o Quality baked in; not an afterthought
o Reliable, secure, and maintainable software
Cost - Defect prevention and reduction
Time - Get our life back in order
o Predictability
