Write about Water-fall model and give the cons and pros of the model?

Water-fall model:

• Oldest software lifecycle model & best understood by upper management

• Used when requirements are well understood, and risk is low

• Workflow is in a linear fashion.

• Used often with well-defined adaptations or enhancements to current software

Disadvantages:

• Real projects rarely follow the sequential flow.

• Difficult for customers to state all requirements explicitly and up front

• Requires customer patience because a working version of the program doesn't occur until the final phase

• Doesn't support iteration, so changes can cause confusion and Leads to “blocking states”.

Advantages:

• Where requirements are fixed and are to proceed to completion in a linear manner.
