What’s this talk about?
• Understanding industrycontext that’s useful toknow when you areadopting agile.
• What Agile teams aredoing that might be hard towork out from the books.
Why does it matter?

I’ll be talking about the form of Agile which I seeteams actually do.

Methodologists United!
“I kicked off "The LightweightProcess Summit" with a 10minute plea for a manifesto, andthen watched with awe and gleeas these people, with some deepphilosophical differences, foundthemselves in fundamentalagreement with the notion thatwhat we shared in common wasmore important than ourdifferences.”Bob Martin re: Agile Manifesto

Banging the Drum
Keeping a method simple makesit easy to transmit and easy tounderstand.
Agile methods can help you getstarted but you have to fill inthe gaps.
What am I seeing teams do?
• I work with Scrum teams who use XP practiceslike Velocity, Test-Driven Development andUser Stories describe their Product Backlog.
• I work with XP teams who use Burndowncharts, Retrospectives and Daily Scrum format.
• I work with Lean teams who use a mix of theabove.
• It seems a generic Agile mashups are emerging.
Sorry, No again! Work out new Agile practice gradually through Retrospectives
The 13th Practice?

XP SCRUM
Mashup Zone
Teams create their own agile “mashups”

How XP are you?
Can you claim to be an XP team ..• if you don't use index cards?• if you don't write code test-first?• if you don't program in pairs?• if you don't sit together?• If you don’t have an onsite customer?It seems that some practices are more optional
than others
How Scrum are you?Can you claim to be a Scrum team ..• if you don't have a Sprint Review?• if you don't deliver a Product Increment at the
end of each Sprint?• if you don't have a Sprint Retrospective?• if you don't have a visible Sprint Burndown?• if you don't have a defined Sprint Goal?• if your Product Backlog is not prioritized?Maybe there’s a good reason why you don’t?

Agile Roles
Between 5 and 10 team members• Cross-functional including at least one tester• Self-organizing
The Team
Split the Customer (ProductOwner) role
The Truth works with support ofcommittees, management,customers, sales people, but is theonly person that makes decisionsabout priorities
With a trusty sidekick …
The Truth
The Voice of the Customer
The Voice of the Customeris typically an analyst whoworks closely with theteam to make sure thatuser stories andacceptance tests areconsistent, valuable anduseful.

Start the Day around the Board• Teams start the day with a Daily Standup by their
Project Board using the Scrum question format.• The Project Board shows what the team are working
on today and how much is left.

Conformity?• Scrum says “Inspect & Adapt”• Manifesto says “the team reflects on how to become
more effective, then tunes and adjusts its behavioraccordingly.”
• Your team will be different and that’s OK :-)
Agile Books
• Use as source of ideas• Not “religious” texts• Read more than one!
No, I’m not suggesting we need this.Project are too varied so we need loose Agile.The Agile Manifesto already serves the purpose
of a framework.
Unified Agile v2.0?
Any Questions?
