1. Digital Revolution
When companies need to evolve together with their
customers and with their technology environment
2. Information Systems Revolution
Master the new set of tools, the new ways of working
… because “software is eating the world”

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
