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 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

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

AFTER

Directly responsible for prioritization of backlog

Define minimal viable product together


Suppliers

BEFORE

Large releases every 6 – 12 months

Service Level Agreements


AFTER

Small and frequent releases

100% availability

Suppliers

Co-sourcing


Your CD pipeline has to be 100% available

Dependence on Technology:

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

Chain


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
