Staying in Touch with Digital Customers
l Markets Are Conversations –
Listen and reply J
l Our Customer Is The Architect of Her Own Experience
l Pulling Opportunities from Customer Intimacy
l Complexity and Continuous Change require Agility

No Digital Leader Without
a Software Strategy
l “Software is eating the world”
– M. Andreesen
l Your software sourcing & crafting strategy says
which ecosystems you will be part of
l Agility (both speed and flexibility) is determined
by your software strategy

6. Yves Caseau - Digital Age Information Systems – November 2015 6/20
Constantly Changing Software
Requires New Methods
l Source code becomes more important
(shown, shared and modified)
l Since building is a constant task,
the process becomes more important than the result
l The heart of the game is to constantly learn new skills

7. Yves Caseau - Digital Age Information Systems – November 2015 7/20
Platforms, APIs & Open Source Practice
l White-box integration with source code
l There is a treasure trove of value in the existing open source
communities
l APIs is a service architecture game :
modularity, event-oriented architecture, data exposition
l Good software is built incrementally through feedback

Part Two : Information Systems Revolution
The Compass

9. Yves Caseau - Digital Age Information Systems – November 2015 9/20
The New Way of Working
of Web’s Giants
l “Measure Obsession”
l The most precious currency
in the digital world is the customer’s time
l Build versus Buy
l Lean Startup and Devops

10. Yves Caseau - Digital Age Information Systems – November 2015 10/20
Platforms Attract Value and
Satisfy Customers
l Need for more and more software,
at cheaper prices
l The need for constant innovation implies open innovation
l Enroll ecosystems to develop your software
l The platform game is “give and take”

11. Yves Caseau - Digital Age Information Systems – November 2015 11/20
Design Emotional
Smartphone Experiences
• Smartphone revolution is
more than Mobile Web
• Apps should support daily conversations:
Content strategy is necessary
• “Do one thing really well”
• Design “to reduce friction & to increase pleasure”

12. Yves Caseau - Digital Age Information Systems – November 2015 12/20
A New Toolbox :
Programming Has Changed !
l Test: do you write code ?
do you Google it ?
l Welcome to massively distributed
programming (e.g., from big data to connected objects)
l Systems programming, no longer computers
l Advanced AI and machine learning algorithms
are available as open source libraries

13. Yves Caseau - Digital Age Information Systems – November 2015 13/20
« Data is the New Code » :
Big Data Disruptions
l Cost and technology disruption
l “Data is becoming at heart of
Computer Science”. T. Hoffman
l A new way of programming : data-oriented, sub-linear,
machine-learning grown
l Each Web Giant is investing massively to be ahead of its
Big Data game

14. Yves Caseau - Digital Age Information Systems – November 2015 14/20
Part Three : Software Factories
The Target

15. Yves Caseau - Digital Age Information Systems – November 2015 15/20
Software Factories :
Focus on Building & Automation
l Continuous build,
integration and delivery
l A process that is run continuously must be automated
l DevOps : manage Infrastructure a code and lean cross-
function collaboration

16. Yves Caseau - Digital Age Information Systems – November 2015 16/20
Lean Software Factory :
Cross-functional Team Practices
l Cross-functional teams that live,
eat and breathe together
l Team Problem solving : Kaizen to learn collaboration
l Visual Management : systemic thinking / stigmergy
l Kanban to reduce WIP and streamline handovers

17. Yves Caseau - Digital Age Information Systems – November 2015 17/20
Love your Code and
Value your Software Teams
l Code reviews and pair programming
l Coding standards, discipline and pride
l Incremental development produces junk.
Constant refactoring is mandatory (tending the garden)
l Value your teams : let them learn J
