Agenda

INTRODUCTION

CHANGING WORLD

WHAT WE DID AT ING

CHALLENGES

Technology is changing faster every year

From 0 to 1 billion smart phones

In less than 10 years

People’s expectations grow along

Both customers and employees

Access anytime anywhere anyhow

Zero tolerance for digital failure

Be amazed by new features

Complete industries are changing

Spotify and Netflix are obliterating video and record stores

As a Bank We are not Immune

Traditionally people deposited their money into banks

It was kept in safes

And accessed through checks

You don’t need 150 years of tradition to start a bank anymore

Technology opens the door to many more competitors

…and perhaps takes banks out of the equation

People Need Banking

not banks

The Specs

The PiD

The Development

CHANGING REQUIREMENTS

DESIGN FAILS

The Testing

DEPLOYMENT ISSUES

The Result

To stop this …

You have to speed up your delivery cycle

Agile Scrum Made the First Move…

…but the next bottleneck is deployment on production

Continuous delivery

Every change tested on production like environment

Continuous delivery

Multiple deploys on preproduction per day

Releasing becomes business decision

Everything is automated

Configuration management

Testing

Deployments

Bridge the gap between Dev and Ops

DevOps

Dev and Ops working together in one team with one backlog

A NEW way of working

The Dream

The Demo

The Minimal Viable Product

The Second Release

Agenda

INTRODUCTION

CHANGING WORLD

WHAT WE DID AT ING

CHALLENGES

Biggest challenge is people

Mindset & Behaviour

Engineering culture

Stakeholders

Suppliers

CD will fail without the right mindset and behavior

Start where it hurts

Realize Improvements Every Three Months

Patience

How to transform your workforce?

Training

Attract the Best Talent in the World

CD talent is rare

War on talent

Engineers look for great engineering, not money

Be content leaders yourself

Business stakeholders

BEFORE

We cannot deliver on the agreed time lines

That is not our fault

We need a lot of money for things you do not understand

Business stakeholders

Directly responsible for prioritization of backlog

Define minimal viable product together

Suppliers

BEFORE

Large releases every 6 – 12 months

Service Level Agreements

Small and frequent releases

100% availability

Suppliers

Co-sourcing

Your CD pipeline has to be 100% available

Dependence on Technology:

Agenda

INTRODUCTION

CHANGING WORLD

WHAT WE DID AT ING

CHALLENGES

What if we’re only halfway there?

Role based access should be standardized

Automated security

Security settings deployed as part of the pipeline

CD pipeline as a service

We want to build banking software, not automation

As many as 50 teams working on one release

Where Does it Stop: Continuous Delivery in a Bank

Secure financial service

Managing a customer’s financial future is not like streaming video’s

There is a danger of blindly following Google, Spotify

and Netflix
