The Good and Bad of Waterfall

The good parts of using waterfall migration are:

  • Traditional approach with fixed scope.
  • Increased redundancy with development and testing environment.
  • Increased testing and issue management.
  • Tight control of changes from one environment to another.

By using waterfall approach, you need to anticipate these bad situations that will arise:

  • Increased duration from additional environment setup.
