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

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

– 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.

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