Who am I?

I am responsible for developing, delivering and operations

I am a change manager

I am a mentor

I enable business

I search for innovation

I remove barriers and build bridges

I am the hedgehog in our IT wallet

I am a father

I am a horseman

Seite 7

What problem do we have to solve?

the classic DEV vs. OPS problem

Seite 8

DEV:

developing new featureswill be able to change everything

will be fast and independentTesting features in DEV

use all the new tech stuff

OPS:

keep the platform stableHave to wake up at 02:00 amHave to know what changed

OPS is not a test stagebe able to fix everything

the DEV stage doesn’t look like the OPS stage

Think & Talk

Seite 9

Core Principles

think big and learn to break things (disruption) Understand which markets, industries, service are not transparent or efficient

Reduce complexity in the core of the respective market/industry/service

customer value driven Stop doing things customers do not value – value is decided by the customer not by us

based on insights or hypothesis’ test/learning

start small and learn fast start small with a minimum viable product (MVP)

Done is better than done perfect

Measure to learn and learn fast – kill quickly

speed independent services & technology layers

continuous deployment

optimize for speed and flexibility not only efficiency

end-2-end responsible teams reduce handovers and

enable multidisciplinary actions

independent and autonomous teams

buildlearn

mea-sure

dis-cover

Seite 10

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

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” managementinto 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

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 controlinto servant leadership

I have to empower them to become a coach

Seite 13

Organize people

to match

the business

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 trustSeite 14

Devops & Agile

development

It is necessary to involve ALL other teams in Agile

Try to become a Agile company, not only a Agile IT
