Agile Development Methodology

Agile project management focuses on continuous improvement, scope flexibility, team input, and delivering essential quality products. Agile project management methodologies include scrum, extreme programming (XP), and lean, among others. These methodologies all adhere to the Agile Manifesto and the 12 Agile Principles, which focus on people, communications, the product, and flexibility.


A Manifesto for Agile Software Developers

The Agile Software Development Manifesto© is an intentionally streamlined expression of the core values of agile project management. Use this manifesto as a guide to implement agile methodologies in your projects.

"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
  • Patient File Management
  • 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."

The 12 Agile Principles

The 12 Agile Principles are a set of guiding concepts that support project teams in implementing agile projects. Use these concepts to implement agile methodologies in your projects.

  • 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.
