REASONS FOR BEING AGILE

Its Cool and Everyone is doing it

Don’t want to Fail

Hate Process, Plans and Docs

Competitive Edge, Winning and making lots of Money

AGILE MANIFESTO

Individuals and interactions over processes and tools Working software over comprehensive documentation

Customer collaboration over contract negotiation

Responding to change over following a plan

WHY DO RELEASESCRASH AND SLOW DOWN?

DO YOU DOPERFORMANCE TESTING

ON EVERY RELEASE?

Be Honest.

THE PROBLEM

• Reproducing Production isn’t fast, easy or cheap

• SOA, Databases, 3rd Party Services

• Cloud Platforms aren’t Mature Enough

• Endless battle to update Test Scripts

• Functional over Non-Functional requirements

What’s this?

THE NEW PORSCHE SUPER CAR

• 918 Spyder

• 600,000 Euro’s and 150,000 Deposit

• 3 Engines & 50 Onboard Computers

• 780bhp & 950Nm (0-100Km/h in 3 secs)

• 94mpg & 70g CO2/KM

WHAT IS PORSCHE FAMOUS FOR?

Engineering Excellence Winning Races

Quality

Smug Owners Bad Drivers

Innovation

ENGINEERING EXCELLENCE

IS HIDDEN

JUST LIKE IN APPLICATIONS

WHAT MATTERS IS

The User ExperienceHandling, Performance, Sound, Reliability, Comfort, Looks

WHY?

Engineering Excellence alone doesn’t sell cars.

WHY ARE PORSCHE SUCCESSFUL?

• Engineering & Innovation

• PDK, VTG, PCCB, PTM, PASM

• Automation & Efficiency

• Resource, Build Assembly, Unit & Integration Testing

• User Experience Testing

• Thousands of test miles (e.g. Nurburgring, Nardo, ...)

• No Compromise Approach

WORKING SOFTWARE CAN BE FUNCTIONALLY PERFECT

But what about the End User Experience?

DELIVERINGUSER EXPERIENCE

• Worlds #1 Travel Portal

• 4 Dev Teams in 4 Locations

• 3 Teams each do 3 week sprints

• 1 Team Tests in Production

ISN’T TESTING INPRODUCTION SCARY?

Only if you don’t manage the risks.

#1 TRAVEL PORTAL

• Partially Deploy new release to 2/200 Production JVM’s

• Leverage Tools (Application Performance Management)

• Deploy, Monitor, Optimize, Patch, Deploy

• Deploy to 50 & 200 JVMs once Dev is confident

• Being Agile isn’t just a Development Exercise

SUMMARY

• Deliver User Experience not just Code

• Test with Production Data or Test in Production

• Be Agile in Production not just Development

• Agile is about Business Results not Frequent Change

• Deliver Tangible Success, Ask for a Pay Rise!
