have studies some of important models and compare them.
These models have been categorized into two i.e. Software

Software process models have been applied for many years
in an effort to bring order and structure development. Each
of these conventional models suggests a somewhat
different process flow, but all perform the same set of
generic framework activities: Communication, Planning,
Modeling, Construction, and deployment. Review also
provides the progress in software quality models and
practices that can be applied today to achieve the quality of
finished product.
