- 4. How is a software created?
- 5. Someone wants a software to meet his needs investigates and assigns some people to create one with required features, that’s called REQUIREMENTS
- 6. And, some of these people draw something, that’s called DESIGN
- 7. Then others type the statements, follow the design , that’s called CODING
- 8. After that, other execute the software to make sure it meets the requirements, that’s called TESTING
- 9. Hopefully, a SOFTWARE will be released with full related documents, CONTRACT will be paid, CUSTOMER will be over-‐satisfied Wonderful ending…

- 12. Why?
- 13. !
- 15. HOW DOES SCRUM TEAM CREATE A SOFTWARE ??
- 16. Someone wants a software to meet his needs, investigates and assigns some people to create one with requiredfeatures, that’s called REQUIREMENTS
- 17. Software creation work is assigned to Development team This team work together and do Planning What will be done in next month/week to have (some) completedfeature(s) to releaseat end of next month/week
- 18. Result of planning meeting is a Plan that includes goals followed by work that needs to completed in this month/week
- 19. Work is disseminated to each team member. Members will work with close collaboration The team has daily meeting L 15 minutes/day to update, check the working progress, and fix rising issues.
- 20. Just-‐in-‐time update plan if necessary
- 21. Iterate working till end of time box
- 23. RELEASABLE software What will we have?
- 24. Not done yet, development team should have a reflection meeting HOW did team WORK? Could team work BETTER? Try to find out some points that should be IMPROVED in next month/week
- 26. Scrum Framework
- 27. Differences?
- 28. Scrum concentrates on: Collaboration over document Customer problem solving over contract signing Scrum quickly respond to changes! Customers can receive software right after one month, or one week

- 36. BEHIND THE SCENES ...
- 37. Agile Manifesto We are uncovering better ways of developing software by doing it and helping others to do it. Through this work we have come to value: Individuals and interactions over processes and tools Working software over comprehensive documentation Customer collaboration over contract negotiation Responding to change over following a plan That is, while there is value in the items on the right, we value the items on the left more.

- 38. Just-‐in-‐time Daily update Daily Standup Plan, responding to change
- 41. Why Agile?
- 42. Agile now!
- 43. Agile now Each team has 2 people: -‐ 1 controls with commands: GO, STOP, TURN LEFT, TURN RIGHT -‐ 1 follows another’s commands è Goal: In 30 seconds, make highest number of “high quality steps”.
- 44. Why Agile? As in US law 100% projects of Ministry of Defence must use Agile! 42% 49% 9% Successful projects Thành công Thử thách Thất bạiSuccessful Challenged Failed

- 46. Lean Startup Assumption, experimental Feedback data Problems? Solutions?
- 48. Minimum Viable Product Product has minimum feature, fast release • No extra features • Optimize from feedback data Build
