No Digital Leader Without No Digital Leader Without a Software Strategya Software Strategy

“Software is eating the world” – M. Andreesen

Your software sourcing & crafting strategy says which ecosystems you will be part of

Agility (both speed and flexibility) is determined by your software strategy


Constantly Changing Software Constantly Changing Software Requires New MethodsRequires New Methods

Source code becomes more important (shown, shared and modified)

Since building is a constant task, the process becomes more important than the result

The heart of the game is to constantly learn new skills


Platforms, APIs & Open Source Practice Platforms, APIs & Open Source Practice

White-box integration with source code

There is a treasure trove of value in the existing open source communities

APIs is a service architecture game : modularity, event-oriented architecture, data exposition

Good software is built incrementally through feedback

The Compass


The New Way of Working The New Way of Working of Web’s Giantsof Web’s Giants

“Measure Obsession”

The most precious currencyin the digital world is the customer’s time

Build versus Buy

Lean Startup and Devops


Platforms Attract Value and Platforms Attract Value and Satisfy CustomersSatisfy Customers

Need for more and more software, at cheaper prices

The need for constant innovation implies open innovation

Enroll ecosystems to develop your software

The platform game is “give and take”


Design Emotional Design Emotional Smartphone Experiences 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”


A New Toolbox : A New Toolbox : Programming Has Changed !Programming Has Changed !

Test: do you write code ? do you Google it ?

Welcome to massively distributed programming (e.g., from big data to connected objects)

Systems programming, no longer computers

Advanced AI and machine learning algorithms are available as open source libraries


« Data is the New Code » : « Data is the New Code » : Big Data DisruptionsBig Data Disruptions

Cost and technology disruption

“Data is becoming at heart of Computer Science”. T. Hoffman

A new way of programming : data-oriented, sub-linear, machine-learning grown

Each Web Giant is investing massively to be ahead of its Big Data game


Part Three : Software FactoriesPart Three : Software Factories

The Target


Software Factories : Software Factories : Focus on Building & AutomationFocus on Building & Automation

Continuous build, integration and delivery

A process that is run continuously must be automated

DevOps : manage Infrastructure a code and lean cross-function collaboration


Lean Software Factory : Lean Software Factory : Cross-functional Team PracticesCross-functional Team Practices

Cross-functional teams that live, eat and breathe together

Team Problem solving : Kaizen to learn collaboration

Visual Management : systemic thinking / stigmergy

Kanban to reduce WIP and streamline handovers


Love your Code and Love your Code and Value your Software TeamsValue your Software Teams

Code reviews and pair programming

Coding standards, discipline and pride

Incremental development produces junk.Constant refactoring is mandatory (tending the garden)

Value your teams : let them learn

Digital Asset Maturity ModelDigital Asset Maturity Model

API Maturity Engagement Platform

Mobile-centricUser Experience

Digital Software-centric Culture

Level 1 API exposure Cloud stack & open source

Mobile first – obsessed with customer’s time

Grow skills versus hire

Level 2 Open API Devops : continuous delivery

Conversation centric – content strategy

Developers contribute to product design

Level 3 Micro-service Architecture

Analytics & Big Data Leverage all smartphone technologies (sensors & OS)

Cross-functional autonomous teams

Level 4 (Jeff Bezos memo) : All services expose API

Machine Learning & continuous adaptation

Emotional design Co-development with customer in continuous loop

ConclusionConclusion

Software is eating the world => become a software company Build you own software Be the best at what you do Empower those who build

From customer to code, from code to customer Lean Startup Product Development Lean Softfware Factory (Devops) Each relies on the other

It’s a new world ! New kinds of software objects From projects to continuous flow of products Networks of cross-functional autonomous teams
