8. What problem do we have to
solve?
the classic DEV vs. OPS problem
Seite 8
DEV:
developing new features
will be able to change everything
will be fast and independent
Testing features in DEV
use all the new tech stuff
OPS:
keep the platform stable
Have to wake up at 02:00 am
Have to know what changed
OPS is not a test stage
be able to fix everything
the DEV stage doesn’t look like the OPS stage

9. Think & Talk
Seite 9

10. Core Principles
à think big and learn to break things (disruption)
à Understand which markets, industries, service are not transparent or efficient
à Reduce complexity in the core of the respective market/industry/service
à customer value driven
à Stop doing things customers do not value – value is decided by the customer not by us
à based on insights or hypothesis’ test/learning
à start small and learn fast
à start small with a minimum viable product (MVP)
à Done is better than done perfect
à Measure to learn and learn fast – kill quickly
à speed
à independent services & technology layers
à continuous deployment
à optimize for speed and flexibility not only efficiency
à end-2-end responsible teams
à reduce handovers and
à enable multidisciplinary actions
à independent and autonomous teams

11. OK, but how to get there?
We have to change our mindset and behavior
Seite 11
We have to set the right goals for DEV
and OPS (at best the same!)
We have to ensure transparency
We have to share the tools
We have to share the pain
We have to share the success
We should think DEVOPS

12. I am a Manager,
not a DEV or OPS
I am the man in the middle between DEV and OPS
I can make change happen
I have to change my role from classic “command and control” management
into servant leadership
I have to decide if I want to remain the manager or
if I want to be the coach of the team
Seite 12

13. I am not the only Manager
I am part of a manager team
I have a team of (change)managers
They have to change their own role from command and control
into servant leadership
I have to empower them to become a coach
Seite 13
Organize people
to match
the business

14. What to do?
Define clear goals and communicate them
Define clear constraints
Offer assistance, and be available when needed!
Communicate our commitment
find right minded employees
Use the speed of trust
Seite 14

15. Devops & Agile
Agile has become mainstream for product
development
It is necessary to involve ALL other teams in Agile
Try to become a Agile company, not only a Agile IT
Be able to concentrate on how to build a feature
If you be Agile in a right way, you only have to scale
your business
