Software development wasn’t always as easy…

It took us a lot of discovery to find our way…

Developers have always looked for “better ways”

What did we gain?
• We have gained tremendously from those innovations
– Earlier and more predictable releases
– Improved quality
– Flexibility / allows for changes
– Cost control

What we tend to forget

IT IS FOR BUSINESS(i.e. for the business to make more money or spend less money – yep, that’s it!)

And what we now MUST all realize…

IT IS FOR BUSINESSIT IS BUSINESS

Repeat after me: BUSINESS  IT
17
SOFTWARE IS EATING
YOUR WORLD AS WELL!

17. ©2015CloudBees,Inc.AllRightsReserved
How to get there?
• We have to essentially bring the “Development Smartness” and apply
it to … the business as a whole!
• This is not just how we develop “software”…
• But how that software takes place in the business differentiation
– How business requirements & objectives get defined
– How we structure “Business” teams to deliver value through software
– How frequently do we release software How frequently do we gather
feedback

• A « Pipeline » defines all of the step that go from code-to-production
• Your software must always be in a “release-ready” stage
Problem:
FAST_ITERATION + FRICTION => HEAT!
Continuous Delivery – Define your pipeline!

STEP “0”: EMBRACE CI

STEP 1: EMBRACE DEVOPS AND CD
ProdDev BuildCommit Test Stage Deploy
Feedback Loop
Feedback Loop
1. Simply a BETTER WAY!
2. Doesn’t require changes
OUTSIDE of IT

26. ©2015CloudBees,Inc.AllRightsReserved
STEP 2: EDUCATE THE BUSINESS
ProdDev BuildCommit Test Stage Deploy
Feedback Loop
Busi-
ness
Project
Team
Feedback Loop
1. Natural extension!
2. YOU are the best positioned
to explain what’s happening
on the market and how you
can benefit from this! You are
the new Rain Maker!

27. ©2015CloudBees,Inc.AllRightsReserved
STEP 3: START SMALL
• Pick a Proof of Concept (PoC) project
• Aim for “easy”, “non-critical”, “no edge cases”
• Pick a MOTIVATED TEAM
– dynamic, eager to learn and change, etc.
– MUST INCLUDE ALL TEAMS, INCLUDING BUSINESS!
• THE GOAL HERE IS TO WIN AND DEMONSTRATE
VALUE
– SO… WIN!
28

STEP 4: ADVERTISE YOUR WIN
• Now is time to BRAG! 
• Show the value, show metrics (time, risk, market-
fit, etc.)
• Make it a BUSINESS CASE, not a technical one
– Remember business == IT
29

29. ©2015CloudBees,Inc.AllRightsReserved
STEP 5: ITERATE!
• Rinse and repeat!
• Use your PoC team to train other teams, they are now
your in-house experts!
• Start small and grow big
• BIG BANG approaches never work. Ever.

Why should it matter to you – as a developer?
• INDUSTRIALIZATION has profoundly impacted work
organization, tools and processes
• Businesses are entering a similar transformation
– IT is not just a way to optimize back-office operations anymore…
– IT becomes core to the products/services, IT is the business
• As a software developer you have first hand expertise on
how this can be applied to your business
 SOFTWARE DEVELOPERS ARE THE NEW KING
MAKERS! 31

Conclusion
• IT “industrialisation” has started
• Software is what will make – or – kill companies
• Developers have a HUGE OPPORTUNITY
ahead…
• … But also a GREAT RESPONSIBILITY
YOU MUST RING THE WAKE-UP CALL
