      What are the pros & cons of the Waterfall model?

    • #52864

      – This model is preferred for smaller projects where requirements are well understood.
      – It is less expensive as minimal resources are required.
      – The output formed at the end of each phase is reviewed and approved and hence it has high visibility.
      – The main strength of the Waterfall model is its simplicity and it is very simple to use.
      – Minimal resources are needed.

      – It is hard to implement any changes in the requirements.
      – Not suitable when requirements are not clear.
      – It is expensive to incorporate any changes once the project is into the testing phase.
      – No working software is produced until the last stage of the life cycle.
      – Not suitable for complex projects, long term projects.
