Dynamic Systems Development Method (DSDM)

DSDM is an agile software development methodology. It is an iterative, incremental approach that is largely based on the Rapid Application Development (RAD) methodology. The method provides a four-phase framework consisting of:

  • Feasibility and business study
  • Functional model / prototype iteration
  • Design and build iteration
  • Implementation

Within each phase, DSDM relies on several different activities and techniques based on these principles:

  • Projects evolve best through direct and co-located collaboration between the developers and the users.
  • Self-managed and empowered teams must have the authority to make time sensitive and critical project-level decisions.
  • Design and development is incremental and evolutionary in nature and is largely driven by regular, iterative user feedback.
  • Working software deliverables are defined as systems that address the critical, current business needs versus systems that address less critical future needs.
  • Frequent and incremental delivery of working software is valued over infrequent delivery of perfectly working software.
  • All changes introduced during development must be reversible.
  • Continuous integration and quality assurance testing is conducted in-line, throughout the project lifecycle.
  • Visibility and transparency is encouraged through regular communication and collaboration amongst all project stakeholders.
