What are Agile Methods and Attitudes? - UML

Agile developmentmethods usually apply timeboxed iterative and evolutionary development, employ adaptive planning, promote incremental delivery, and include other values and practices that encourage agility - rapid and flexible response to change.

Evolutionary analysis and design the majority in early iterations

It is not possible to exactly define agile methods, as specific practices vary widely. However, short timeboxed iterations with evolutionary refinement of plans, requirements, and design is a basic practice the methods share. In addition, they promote practices and principles that reflect an agile sensibility of simplicity, lightness, communication, self - organizing teams, and more.

Example practices from the Scrum agile method include a common project work room and self - organizing teams that coordinate through a daily stand - up meeting with four special questions each member answers. Example practices from the Extreme Programming (XP) method include programmingin pairs and test - driven development.

Any iterative method, including the UP, can be applied in an agile spirit. And the UP itself is flexible, encouraging a "whatever works" attitude to include practices from Scrum, XP, and other methods.

The Agile Manifesto and Principles

The Agile Manifesto

  • Individuals and interactions
  • Working software
  • Customer collaboration
  • Responding to change
  • over processes and tools
  • over comprehensive documentation
  • over contract negotiation
  • over following a plan

The Agile Principles

  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 processes 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 to the shorter time scale.

  4. Business people and developers must work together daily throughout the project.

  5. Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done.

  6. The most efficient and effective method of conveying information to and within a development team is face - to - face conversation.

  7. Working software is the primary measure of progress.

  8. Agile processes promote sustainable development.

  9. The sponsors, developers, and users should be able to maintain a constant pace indefinitely.

  10. Continuous attention to technical excel lance and good design enhances agility.

  11. Simplicity the art of maximizing the amount of work not done is essential.

  12. The best architectures, requirements, and designs emerge from self - organizing teams.

  13. At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.
