  • Provides good development cycle feedback at each function/ feature implementation and data can be used as reference for similar product development in future.
  • More responsive to changing user needs.
  • Provides a working model with minimum features at first cycle itself.

  • Product development can be stopped at any stage.

Drawbacks –

  • Extensive review requirement impact on operations due to new releases.
  • Training for each new deployment.
