The document presents a comprehensive overview of Agile and DevOps principles, emphasizing the cultural and technological practices that enable efficient software delivery. It highlights the importance of continuous integration, testing, and collaboration across teams while contrasting traditional methods with modern approaches that focus on reducing lead times and improving quality. Key takeaways include the necessity of fostering a generative culture and implementing systematic processes for continuous improvement within organizations.

11. Misguided Performers Suffer from Cautious Approach
• Organizations that take a cautious approach to software
development and deliver.
- Release code infrequently
- Uses extra time for testing and other quality checks.
• Data shows
- Low deployment frequency
- Long lead time for changes
- Better change failure rates than low performers
- Longest time to fully restore service
• Large batch releases introduce risk in the release.
- While customers may be back on the system in the hour, it
can take between 1 month and 6 months to find, fix, and
deploy the fix to what caused the initial failure

16. DevOps as a Catalyst
17@LelandNewsom

17. Definition of DevOps
18
DevOps is those set of cultural
norms and technology
practices that enable the fast
flow of planned work from,
among others, development,
through tests into operations
while preserving world class
reliability, operation, and
security.
DevOps is not about what you
do, but what your outcomes
are.
@LelandNewsom

18. What is DevOps Culture
• Shared values and behaviors
• There’s no right culture for DevOps, but there are characteristics:
- Respect and Trust
- High Psychological Safety
- High Cooperation
- Open Communication
- Good flow of Information
- Collaboration
- Flexible
- Supportive
- Open to experimentation
- Continuously improving

Typology of Organizational Culture (Westrum, 1994)

21. How to Build a Generative Culture
Characteristics of a
Generative Culture
DevOps Practices
High Cooperation Cross-functional teams. Create cross-functional teams that include representatives from each functional area
of the software delivery process.
Messengers trained Blameless Postmortems. By removing blame, you remove fear, you enable teams to more effectively surface
problems and solve them. Mistakes happen; holding blameless postmortems or blameless problem
solving/issue resolution is a valuable way to learn from mistakes.
Risks are Shared Shared Responsibility. Quality, availability, reliability, and security are everyone’s job. The improvement in
collaboration that comes from sharing responsibility inherently reduces risk.
Bridging encouraged Breaking down silos. In addition to creating cross-functional teams, techniques for breaking down silos can
include co-locating or embedding ops with the dev team or including ops in planning throughout the software
delivery lifecycle.
Failure leads to inquiry Blameless postmortems. Your response to failure shapes the culture of the organization. The more you focus
on the conditions in which failures happen, as opposed to blaming individuals for failures, the closer you’ll get
to creating a generative culture.
Novelty implemented Experimentation Time. Giving employees freedom to explore new ideas can lead to great outcomes. Some
companies give engineers time each week for experimentation. Others host internal hack-a-thons or hold
internal conferences to share ideas and collaborate.

22. Three Ways: The Principles Underpinning DevOps

23. Three C’s of DevOps
24@LelandNewsom

24. Continuous Integration
“Continuous Integration is a software development practice where members of a
team integrate their work frequently, usually each person integrates at least daily -
leading to multiple integrations per day. Each integration is verified by an automated
build (including test) to detect integration errors as quickly as possible. Many teams
find that this approach leads to significantly reduced integration problems and allows
a team to develop cohesive software more rapidly.”
-Martin Fowler

35. Risk Mitigation in Continuous Delivery
Goal: Increase release frequency and not increase risk.
• Decouple releases from deployments & development cadence
• Application-based patterns
• Feature toggles
• Dark launches
• Use Environment-based release patterns
• Canary Releases
• Blue-Green pattern
36Blue-green deployment pattern (Source Humble and North, Continuous Delivery, 261).
