Answer Posted / murari
he Systems Development Life Cycle (SDLC) is a conceptual
model used in project management that describes the stages
involved in an information system development project
from an initial feasibility study through maintenance of the
completed application. Various SDLC methodologies have been
developed to guide the processes involved including the
waterfall model (the original SDLC method), rapid
application development
(RAD), joint application development (JAD), the fountain
model and the spiral model. Mostly, several models are
combined into some sort of hybrid methodology. Documentation
is crucial regardless of the type of model chosen or devised
for any application, and is usually done in parallel with
the development process. Some methods work better for
specific types of projects, but in the final analysis, the
most important factor for the success of a project may be
how closely particular plan was followed.
The image below is the classic Waterfall model methodology,
which is the first SDLC method and it describes the various
phases involved in development.
