Agile development isn't a technique overall. it's a collective term that describes many agile methodologies. At the signing of Agile declaration in 2001, these methodologies enclosed scrum, XP, Crystal, FDD, and DSDM. Since then, lean practices have conjointly emerged as a valuable agile methodology and they have enclosed below the agile development umbrella later.

Each agile methodology contains a slightly some what different approach for implementing the core values from the Agile declaration, even as several programming languages manifest the core options of object-oriented programming in several ways. A recent survey shows that concerning 50 % of agile practitioners say that their team is doing scrum. Another 20 % say that they're doing scrum with XP elements. an extra 12 % say that they're doing XP alone. as a result of over 80 % of agile implementations worldwide are scrum or XP, MSF for Agile computer code Development v5.0 focuses on the core processes and practices of scrum and XP.

Manifesto for Agile Software Development

We are uncovering better ways of developing software by doing it and helping others 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.”

Principles behind the Agile Manifesto

  • We follow these principles: Our highest priority is to satisfy the customer through early and continuous delivery of valuable software.
  • Welcome changing requirements, even late in development. Agile processes harness change for the customer's competitive advantage.
  • Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.
  • Business people and developers must work together daily throughout the project.
  • Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done.
  • The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.
  • Working software is the primary measure of progress.
  • Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely.
  • Continuous attention to technical excellence and good design enhances agility.
  • Simplicity--the art of maximizing the amount of work not done--is essential.
  • The best architectures, requirements, and designs emerge from self-organizing teams.
  • At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.
