The Waterfall model is classical approach to solving engineering problems (most commonly known as an approach to software engineering). It employs a sequential series of activity phases culminating in a single release milestone.

In a typical software life cycle, following the waterfall model produces the following phases and activities:

  • Requirements collection and analysis
  • Software Architecture - design analysis and development
  • Preliminary code development and in-house unit testing
  • Release candidate code development (culminating in a "feature complete" internal release)
  • Alpha Phase: System level and integration testing
  • Beta phase: Qualified external users test the pre-release software
  • Public Release
  • Maintenance / "bug" fixes
