  6. 6. What is Agile Development?Agile software development is a group of software development methods based on iterative andincremental development, where requirements and solutions evolve through collaboration betweenself-organizing, cross-functional teams. It promotes adaptive planning, evolutionary developmentand delivery, a time-boxed iterative approach, and encourages rapid and exible response tochange. It is a conceptual framework that promotes foreseen interactions throughout the developmentcycle. The Agile Manifesto[1] introduced the term in 2001.WIKIPEDIA http://en.wikipedia.org/wiki/Agile_software_development121116
  7. 7. Agile Manifesto Value Principle 1. Our highest priority is to satisfy the customer through earlyand continuous delivery of valuable software. 2. Welcome changing requirements, even late in development.Individuals and interactions Agile processes harness change for the customers competitive advantage.over processes and tools 3. Deliver working software frequently, from a couple of weeks to acouple of months, with a preference to the shorter timescale. 4. Business people and developers must work together daily throughout the project.Working software over comprehensive 5. Build projects around motivated individuals. Give them the environment documentationand support they need, and trust them to get the job done. 6. The most efcient and effective method of conveying information toand within a development team is face-to-face conversation.Customer collaboration 7. Workingsoftware is the primary measure of progress. over contract negotiation 8. Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indenitely. 9. Continuous attention to technicalexcellence and good design enhances agility.Responding to change over10. Simplicity--the art of maximizing the amount of work not done--is essential.following a plan 11. The best architectures, requirements, and designs emerge from self-organizing teams. 12. At regular intervals, the team reects on howto become more effective, hen tunes and adjusts its behavior accordingly.121116

  11. 11. Manifesto for software craftsmanship Not only working software, but also well-crafted software Not only responding to change, but also steadily adding value Not only individuals and interactions, but also a community of professionals Not only customer collaboration, but also productive partnerships http://manifesto.softwarecraftsmanship.org121116
