WHY DO WE NEED
TO CHANGE SOMETHING

4. • “WE ARE USED TO work like this!”
• “Everybody works like this!”
• “We follow sw engineering standars!”
- and-
Change is scary

5. What’s wrong with us?
• Big up front design
• Lengthy never-read documents
• Software is not a manufactured product
• Test when it’s too late
• Client don’t know what they really want
• 100% of the features are 80% complete

6. THERE IS
A DIFFERENT WAY
{Possibly better}

8. Individuals and interactions
Working software
over
over
processes and tools
comprehensive documentation
Customer collaboration
over
contract negotiation
Responding to change
over
following a plan

9. SCRUM
“Scrum is a simple and repeatable way of managing work” (Kelly Waters)

10. Scrum TEAM
self organized team
cross competence
colocated team
Scrum MASTER
protects the team
responsible for the process
coach
Product owner
prioritize the work on the product
he knows what is required for the product
he is committed to the success of the product

11. Done means… done!

12. PROs
• Incremental delivery means revenue
• Speed to market
• Constant feedback loop
• Quality
• Risk management
• Visibility
• Right product
• Changes are welcomed

13. Scrum hell
• Change is scary
• Change needs time (3-4 sprints at least)
• Scrum needs a lot of commitment
• scope creep danger
• agile testing is not for dummies
• “Scrum-but”
Scrum is not a silver bullet!

14. eXtreme
Programming
Where “extreme” is probably not what your are thinking about.

15. Pair programming
Test driven development
Refactoring
Continuous integration
user stories

16. agile
PRACTICES

17. COLOCATED TEAM
no junk on the trunk
30-days free reign
whiteboard
planning poker
retrospectives
bonus: pomodoro technique

18. Now what?

19. be the change
you wish to see in the world
M. Gandhi (so they say…)
better to start top-down
think big start small (pilot)
adopt and share the philosophy
but you need a change in organizational culture
but…
scrum is the new waterfall
