The Principles behind the Agile Manifesto

  • 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 behaviour accordingly.

The Five Principles of Lean

  1. Value – specify what creates value from the customer’s perspective.
  2. The value stream – identify all the steps along the process chain.
  3. Flow – make the value process flow.
  4. Pull – make only what is needed by the customer (short term response to the customer’s rate of demand).
  5. Perfection – strive for perfection by continually attempting to produce exactly what the customer wants.
