Dynamic Systems Development Model Methodology

The Dynamic Systems Development Model was developed in the U.K. in the mid-1990s. It is the evolution of rapid application development (RAD) practices. DSDM boasts the best-supported training and documentation of any of the agile software development techniques, at least in Europe. DSDM favors the philosophy that nothing is built perfectly the first time and looks to software development as an exploratory endeavor.

The nine principles of DSDM are:

  • A focus on frequent delivery of products.
  • Using fitness for business purpose as the essential criterion for acceptance of deliverables.
  • Iterative and incremental development to ensure convergence on an accurate business solution.
  • Reversible changes during development.
  • Requirements that is baselined at a high level.
