The Waterfall Process Model

•Main characteristics:
–Also called classic software life cycle or sequential model
–Process activities (phases/stages) are clearly separated

•Advantages
–Organized approach, provides robust separation of phases.
–Reflects common engineering practice.

•Disadvantages:
– Doesn't cope well with changes required by the client.
–Development teams might wait for each other.
–A working version of the product is available only late.

•Applicability:
–When requirements are well known and few changes are likely to be needed.
–Can be used also for parts of larger software systems.
