organization” - Rouan Wilsenach

29. Benefits of DevOps

30. Teams that practice DevOps deploy 30x
more frequently, have 60x fewer failures, and
recover 160x faster.
- Puppet Labs 2016 State of DevOps Repost

31. Benefits of DevOps
- Faster Delivery of features
- Improved communication and collaboration
- More time to innovate, less bug fixings
- Continuous product delivery
- Productive and happy teams
- Better career development opportunities

32. Building EVP
( Employee Value Proposition )

33. How to DevOps

34. Cultural Shift

35. There are no simple 5 steps to get there. It is
a journey, and people can support it by
working in small batches, making their work
visible, and committing to a blameless
culture that responds to failure with learning
- Jessica DeVita

36. Journey … to find neverland ?

37. No … But a right balance of ...

39. People
● Cultural paradigm shift
● Shared responsibility
● Cross training of skills
● Always asking : Is my application driving business
value ?
● Building quality in the development process
● Forms Autonomous Teams

- Measurement
- Sharing

43. Key Concepts we can adopt

44. Culture
“Even with the best tools, DevOps is just another buzzword if you don't have the right culture.” - Rouan Wilsenach
- Cross Functional Collaboration
- Product / Project Oriented team instead of functional team
- Having a common goal and plan to reach it together as a team
- Blameless Culture
- Autonomous
- Communication Driven Development

45. Automation
- Eliminating repetitive manual works
- Continuous Integration
- Continuous Delivery
- Configuration as Code
- Infra as Code

46. Lean
- Continuous Iterations & Improvement
- Failing fast and failing often

47. Measurement
- Feature usage
- MTTR
- System failures
- Application failures
- Deployments
The first step is to measure whatever can be easily measured. This is OK as far as it goes. The second step is to disregard that which
can't be easily measured or to give it an arbitrary quantitative value. This is artificial and misleading. The third step is to presume that
what can't be measured easily really isn't important. This is blindness. The fourth step is to say that what can't be easily measured really
doesn't exist. This is suicide.
— Daniel Yankelovich "Corporate Priorities: A continuing study of the new demands on business." (1972)

48. Sharing
- Sharing responsibilities, success and failures among teams
- Shared Codebase / Collaboration / Toolset among teams
- Open Information sharing; Go Open Source!
