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

20
Technology opens the door to many more competitors
…and perhaps takes banks out of the equation

People Need Banking
not banks

Biggest challenge is people
Mindset & Behaviour
Engineering culture
Stakeholders
Suppliers

CD will fail without the right mindset and behavior

Training

81
Attract the Best Talent in the World

82
CD talent is rare
War on talent
Engineers look for great engineering, not money

83
Be content leaders yourself

84
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

85
Business stakeholders
AFTER
Directly responsible for prioritization of backlog
Define minimal viable product together

86
Suppliers
BEFORE
Large releases every 6 –12 months
Service Level Agreements

87
AFTER
Small and frequent releases
100% availability
Suppliers
Co-sourcing

88
Your CD pipeline has to be 100% available

92
What if we’re only halfway there?

93
Role based access should be standardized
Automated security
Security settings deployed as part of the pipeline

94
CD pipeline as a service
We want to build banking software, not automation

95
As many as 50 teams working on one release
Chain

96
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
