Who am I?

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 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

Think & Talk

Seite 9

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

build learn

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” 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

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

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

Devops & Agile

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

Seite 15
