WHAT IS DEVOPS?

WHAT IS NOT DEVOPS?

https://en.wikipedia.org/wiki/Site_reliability_engineering
“DevOps is a philosophy of
cross team empathy and
business alignment”
5

https://en.wikipedia.org/wiki/DevOps
“DevOps (a clipped compound of "development" and "operations") is a
software engineering culture and practice that aims at unifying software
development (Dev) and software operation (Ops). The main characteristic
of the DevOps movement is to strongly advocate automation and
monitoring at all steps of software construction, from integration, testing,
releasing to deployment and infrastructure management. DevOps aims at
shorter development cycles, increased deployment frequency, more
dependable releases, in close alignment with business objectives.”

Solving every issue with tech is next to impossible

DEVOPS FOR HIRE?
8

“System Administration”
“Cloud”
“Partner with engineers”
“Linux Master”
“Real programming”
“Higher education degree”

DEVOPS FOR SALE?
10

DEVOPS AS A TOOL?
12

https://en.wikipedia.org/wiki/DevOps
[...]DevOps is intended to be a
cross-functional mode of
working, rather than a single
DevOps tool[...]

“DevOps is a philosophy of
cross team empathy and
business alignment”
17

You can’t buy DevOps, culture evolves and grows
DevOps isn’t a tool, it is non-technical
DevOps can help you deliver faster and more
reliable, but it’s not just that
You can’t hire DevOps, it’s a philosophy
18

WHAT IS IT THEN?
19

So, about the client you
assessed last week? What’s
their issue?
They don’t have a technical problem, they have
an organizational problem!

OUR VIEW OF DEVOPS
Culture is as important as code: Taking responsibility for the whole software
development process - collaborating on ideation, writing code, testing and
releasing - empowers individuals and teams to focus on a value and business
driven development cycle.
DevOps is not a single team or single engineer: Instead it allows engineers to
collaborate, share knowledge and be aware of the bigger picture in diverse and
agnostic teams. Single purpose, homogeneous teams should be a thing of the
past.
Trusting your code: Building incremental, well-tested
software allows for shorter, more trustworthy and more
reliable release cycles with a shared and distributed
responsibility model.
DevOps is cultural shift on an organizational level

Reduce organizational silos
Accept failure as normal
Implement gradual changes
Leverage tooling and automation

THE THREE WAYS
Systems Thinking
Amplify Feedback Loops
A Culture of Continuous
Experimentation and
Learning

“The First Way emphasizes the performance
of the entire system, as opposed to the
performance of a specific silo of work or
department. DevOps transcends departments
and showcases the overall value to the
customer.” – Gene Kim
24

SYSTEMS THINKING
Understand the value stream and success criteria for your product
Identify and leverage the most important contributors to delivering value on
every level
Champion autonomy and collaboration
Don’t blame and shame but rather look for cause and effect
Tackle impediments according to their priority (“Flow” control)*

Measure everything
26

“[...]The goal of almost any process
improvement initiative is to shorten and
amplify feedback loops so necessary
corrections can be continually made.”
– Gene Kim
27

AMPLIFY FEEDBACK LOOPS
Take small, incremental steps
Transparency in everything
Empower customers and stakeholder to share their feedback effectively
Share knowledge and experience
Accurately assess the state of your product at any moment in time

Measure everything
29

“[...] continual experimentation, taking risks
and learning from failure; and
understanding that repetition and practice is
the prerequisite to mastery.” – Gene Kim
30

CONTINUOUS EXPERIMENTATION & LEARNING
Incentivise continuous improvement for the product development cycle
Fail fast, recover fast
Measure your success
Leave room for learning and celebrate achievements
If it hurts, do it more often*

DECOMPOSITION FEEDBACK AUTOMATION
Breaking down complex
systems into viable products
Identifying boundaries and
interfaces
Reduce the scope until you
assign it to a product team
Writing tests is the foundation
of every single process within
modern software delivery; it’s
your feedback driver
Efficient and smart testing
keeps feedback loops short and
valuable
Short feedback loops enable
you to iterate faster, creating
more value and
transparency
Reproducible results without
variance
Never do anything twice, have it
done for you
Enable and empower people to
automate their workloads
