    What are the pros & cons of the Waterfall model?


  • #52864

    Pros:
    – 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.

    Cons:
    – 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.
