the best of tools and standards falling
within the ITIL framework, for all our IT
Solution services. We also follow a combination
of the Waterfall Method and RAD (Rapid Application
Development) Methodology of Software Development.
Competent of delivering highly reliable
systems, the Waterfall method is essentially
a serial method. Being non-iterative, each
stage produces a 'correct' result that does
not then require re-working at a later stage.
In any project, if we have any initiative
dealing with infrastructure (and if its
part of the scope), we use the Waterfall
Methodology most effectively. This is because,
the most important thing is to get things
correct, as this platform will be the bedrock
on which we build the application and test
it, and this would need to stand the test
Rapid Application development methods are
based on the thought that, “it is
better to be quickly there with a system
that meets 80% of the business need. Then
the system delivers relevant business benefits
sooner and does not become quickly overtaken
by events & nor become out-dated.”
Being iterative, in our Rapid method, we
tend to re-visit the outputs of the various
stages during later stages. They are also
mainly parallel methods, in which different
stages may well be worked on at the same
time. For developing content and applications,
we use the RAD Methodology, since in these
scenarios the most important aspect is to
develop solutions that are timely and relevant
to businesses operating in a fast-moving
and competitive environment.
