  3. 3. Doessoftwarefail? 3
  4. 4. How often software fails? 1 • 5 to 15 % of the IT project will be abandoned before or shortly after delivery as hopelessly inadequate • Many others will arrive late and over budget or require massive reworking 4
  5. 5. “Failure is not an option… …it comes bundled with the software” Unknown Auhtor 5
  6. 6. 6 Why waterfall fails more? There are many replies… • Waterfall • Agile/Lean

  8. 8. The new product development game2 “Companies are increasingly realizing that the old, sequential approach to developing new products simply won’t get the job done. Instead, companies in Japan and the United States are using a holistic method as in rugby, the ball gets passed within the team as it moves as a unit up the field.” 8
  9. 9. Manifesto for agile software development3 9 That is, while, there is value in the items on the right, we value the items on the left more.
  10. 10. The 12 Principles of Agile Development 10 They can be divided into four categories4: 1. Delivering the project 2. Communicating and working together 3. Project execution 4. Constantly improving
  11. 11. Delivering the project 11 1. Our highest priority is to satisfy the customer through early and continuous delivery of valuable software 2. Welcome changing requirements, even late in development. Agile process harness change for the customer’s competitive advantage 3. Deliver working software frequently, from a couple of weeks to a couple of months, with a preference for a shorter timescale
  12. 12. ActivityTime 12 What’sinyourteam?
  13. 13. Communicating and working together 13 4. The most efficient and effective method of conveying information to and within a development team is face-to-face conversation 5. Business people and developers must work together daily throughout the project 6. Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done
  14. 14. ActivityTime 14 What’sinyourteam?
  15. 15. Project execution 15 7. Working software is the primary measure of progress 8. Agile processes promote sustainable development. The sponsors, developers and users should be able to maintain a constant pace indefinitely 9. Continuous attention to technical excellence and good design enhances agility
  16. 16. ActivityTime 16 What’sinyourteam?
  17. 17. Constantly Improving 17 10. Simplicity – the art of maximize the amount of work not done – is essential 11. The best architectures, requirements and designs emerge from from self-organizing team 12. At regular intervals, the team reflects on how to become more effective, than tunes and adjusts its behavior accordingly

  19. 19. Be agile… 19 Many Agile Framework describe: • Governance • Time-boxed Strategy • Meetings and Tools SCRUM is just one of many Agile Frameworks DSDM, AUP and many others agile frameworks exist

  21. 21. …Stay Lean! 5 21 Two Principles (JIT and Jidoka) to: • reach organization goals • driven by oranization values • through specific tools and methods Kanban cards and boards were just two lean methods used in Toyota Kanban was choosen as name for aFramework from D.J.Anderson in 2010 Goals Just-In-Time Jidoka Methods and Tools Values
  22. 22. Just-in-time 22 Airport Check In Process Client Arrives Client On Board Three main types of wastes: • Activities not adding value (Muda) • Uneveness (Mura) • Overburden(Muri) Two main objectives: • Eliminate wastes in the process • Defend the process flow
