What is the current state of affairs?

IT today

IT today

•  Faster

•  Cheaper

•  Digitization

•  Disruption

•  New technologies

DevOps

“Another buzzword for build and deployment automation”

“A team that moderates between Dev and Ops”

“You build it, you run it!”

“Isn’t that just a new word for ‘agile’?”

“It’s a mindset thing”

“Of course the new version of our product is ‘DevOps’!”

Perfect confusion of ideas

Let’s check the

“DevOps bible” http://itrevolution.com/books/phoenix-project-devops-book/

DevOps in a nutshell

The 3 ways of DevOps Systems thinking

Amplify feedback loops

Culture of continual experimentation & learning

http://itrevolution.com/the-three-ways-principles-underpinning-devops/

•  Maximize flow (minimize cycle times)

•  Optimize for global goals (holistic view)

•  Never pass defects downstream

•  Limit work in progress

•  Build systems and organizations that are safe to change

Ops Dev Business IT value chain Customer

Holistic optimization

Systems thinking

•  Facilitate constant flow of fast feedback from right-to-left

•  Create quality at source (provide knowledge where needed)

•  Create shared goals and shared pain for everyone involved

•  Implement fast automated test suites

•  Pervasively measure outcome (customer value), not output



•  Create a culture that fosters two things •  Continual experimentation, taking risks and learning from success and failure

•  Understanding that repetition and practice is the prerequisite to mastery

•  Allocate at least 20% of available cycles to non-business requirements

•  Constantly reinforce that improvements are encouraged & celebrated


Continual experimentation and learning

Okay, but …

Why is DevOps not enough?

A bit of background …

Evolution of economy & markets

Formal part of value creation Solution: machine

Dynamic part of value creation

Solution: man

sluggishness/low dynamic high dynamic high dynamic

The historical course of market dynamics and the recent rise of highly dynamic and complex markets

The dominance of high dynamics and complexity is neither good nor bad. It‘s a historical fact.

t 1970/80 today

Age of crafts manu- facturing

Age of tayloristic industry

Age of global markets

1850/1900

Spacious markets, little competition

Local markets, high customi-zation

Outperformers exercise market pressure over conventional companies

We call the graph shown here the “Taylor Bathtub”. The “bathtub” curve

IT today is a key success factor to survive in a post-industrial market

The traditional IT “best practices” are counterproductive because they solve

a completely different problem

We need to rethink IT!
