Advantages of SDLC model :
With an SDLC Model, developers will have a clear idea on
what should be or shouldn’t be built. Since they already
have an idea on the problems that should be answered, a
detailed plan could be created following a certain SDLC
model. With an SDLC model, developers could even create a
program that will answer different problems at the same
time. Since everything will be laid out before a single
code is written, the goal is clear and could be implemented
on time. Although there is a great possibility of deviation
from the plan, a good project manager will take care of
that concern.
With an SDLC Model, programs built will have a clear
documentation of development, structure and even coding. In
case there are problems once the program is adopted for
public use, developers will always have the documentation
to refer to when they need to look for any loopholes.
Instead of testing it over and over again which will stop
the implementation for a while, developers will just look
at the documentation and perform proper maintenance
program. This means SDLC will breathe more life to the
program. Instead of frustrating developers in guesswork if
something goes wrong, SDLC will make sure everything goes
smoothly. It will also be a tool for maintenance, ensuring
the program created will last for a long time.
Disadvantages of SDLC Model:
Thinking about the disadvantages of a SDLC model is like
looking for a needle in the haystack. But the closest
disadvantage anyone could think of SDLC is the difference
between what is written in paper and what is actually
implemented. There are things that are happening in the
actual work that the paper doesn’t see. This gives a good
impression for the clients especially for 3rd party
developers but when the software is actually launched it’s
on a very bad situation. The actual situation of software
development could be covered by fancy paperwork of SDLC.
Another disadvantage of a program or software that follows
the SDLC program is it encourages stiff implementation
instead of pushing for creativity in different software.
Although there are SDLC models where programmers could
apply their creative juices, it’s always in the realm of
what is needed instead of freely implementing what the
developers think of necessary in the present environment.
There are so many things that could be done by developers
if there are no boundaries or limitations in what should be
developed.
