3. Agile Methods The Problem

7. Agile Methods The Response

8. Agile Response Market Needs EMBRACING CHANGE 02 Traditional Agile Time Cost of Change

10. What is Agile? Agile processes are iterative processes that use specific project management and software engineering practices to sustain the delivery of new software functionality every one to four weeks 02

11. Agile Manifesto That is, while there is value in the items on the left, we value the items on the right more. We are uncovering better ways of developing software by doing it and helping others do it. Through this work we have come to value: 02 More Important Important individuals and interactions processes and tools working software comprehensive documentation customer collaboration contract negotiation responding to change following a plan www.agilemanifesto.org

16. Why Iterative Development? knowledge Risk Iterations help acquiring knowledge Of both the problem and the solution Estimation Error Short term is easier to predict and estimate rather than long term Time Iterations 02

17. What makes a development process Agile ? Each iteration delivers working software . The phases in each iteration are nearly concurrent . Team uses specific engineering practices to keep the code base fresh and flexible . Teams are self-managing . Lean principles and techniques eliminate waste whenever possible. 02
