8. Influential Agile Methodologies
• XP (The Past)
• Scrum (The Present)
• Kanban (The Future)

9. eXtreme Programming (XP)
• The first major Agile methodology
• Mostly engineering focused
• XP was a reaction to the traditional
waterfall, mass production way to building
software
– Lean principles

10. Scrum
• The most popular methodology today
• Less engineering focused, XP solved that
– Focused on process and ceremony
• Directly from Lean Manufacturing
– “The New, New Product Development Thing”

11. Kanban
• An agile methodology that stresses pulling
individual work items to completion
– Focuses on visualization
• From Lean: focuses on just in time delivery of
raw materials
– Workers get what they need when they need it, no
sooner
– Limit Work in Progress
– Focus on flow

12. Lean Agile
“We are seeing very little awareness of
lean, and a lot of people think it is a new
concept following on the coat-tails of agile.
L
Agile agile is an engineering method by
However, e
which code is written, and lean is the a
n
process by which to do it, and they dovetail
into each other”
- Fred George, Thoughtworks

13. Lean = Framework for Agile
Practices
Embrace Value Creation & Waste
Reduction
Mixed Development Patterns
Lean Will Drive Success
