15. Why do We Need Agile?

17. It is not the strongest of the
species that survives, nor
the most intelligent, but
rather the one most
adaptable to change
Charles Darwin

18. How Agile Solve Problems

19. Unclear or Unstable Requirements
 Misunderstand customer’s needs
 Cannot response change quickly
 Do a lot of unnecessary features

20. Review with Customers Frequently
Testing Analysis
Coding Design
Iteration 1
Testing Analysis
Coding Design

21. Adjust after Review or Change
change scope
Sprint 2 Sprint 2
Feature 2-1 Feature 2-3
Feature 2-2 Feature 2-4
Feature 2-3 Feature 2-5
Feature 1-1’
Refine original Feature 2-1
result Feature 2-2

22. Pareto Principle (80/20 Principle)
 80% revenue come from 20% features

23. Too Long Tasks
 No one knows his progress until done
 The result could be unacceptable
 Always handle in last minutes

24. Small Tasks, Quick Response

25. Small Test, Fast Feedback
 TDD
 Goal
 Clean code that works
 Rules
 Execution time: 10 min

26. Integration Testing is not Unit Testing
 What was I doing until now?
Test Program
System under test

27. Parkinson’s Law
 Work expands so as to
fill the time available
for its completion

28. Timeboxes Drive Intensity
waterfall
intensity
scrum
time

29. Not Enough Time for Quality
 No time to do testing
 Break old features when implementing new one
 No time to refine old system

30. Agile Is All About Feedback
Release Plan months
Iteration Plan weeks
Acceptance Test days
Daily Scrum one day
Continuous Integration hours
Unit Testing hours
Pair Programming minutes
code seconds

31. Ultimate Weapon
Continuous Make sure all old
Integration features still work
Refine old
Design before
implementation
coding
Test Driven Refactoring
Development

32. No Project Visibility
 Only manager knows the progress
 Cannot help each other in time
 No idea about testing progress

33. Task Board

34. Daily Standup Meeting

35. Low Tech Testing Dashboard
14-35
 Low tech is high tech
 Visualize your testing status Update: 3/7, build 1121
Area Effort C Q Comments
Add tree node High 1 #1341, #1442
Edit tree node Low 1+ Auto build broken
Delete tree node Low 2
Drag tree node Start 3/14 0 Lab is ready
Debug tool Blocked 1 Crash: #1121
