1. Planning – before a program is created, they have to know
what they want to create. Software development companies use
this stage to determine the need of the present market.
Surveys and project proposal are common in this stage. They
sit down and determine what the present market needs.
Management is often involved in this stage as they wanted to
determine what the developers have to do and how it will
impact the market.
2. Design – once the management has approved of the plan and
the budget has been determined for this project, it’s now
time to create the architecture of the program. Developers
will work together and talk about the ways of developing the
program. The workflow of the software is drafted in this
stage. Some software development models approach this stage
in a rather simple manner. The iterative development model
often treats this stage as already the beginning of
software’s actual creation. The initial programs are
creating in this part of development model.
3. Testing – developers have to make sure their created
programs will work well in different environments. The
traditional way of testing usually needs testers so that the
program will be exploited in different manner. On the other
hand, some software developers do not use testers for their
program rather developers get normal and intended users to
test their program. They do not just implement the program
to everyone though, they implement the program in restricted
manner so that they can monitor to software’s performance
and make the necessary adjustments even before the software
is released for general public. The testing stage even
expands to the idea of implementing the software in beta
testing just to make sure it can withstand multiple users at
the same time.
4. Implementation – once testing is finished and the
software is proven good for implementation, it is released
to the public or will be removed from beta version. It’s
expected that on first days, developers will face serious
challenge of fixing different bugs as they are discovered
one by one by different users. The main difference of the
implementation stage to the testing is the amount of bugs
expected. Since they are implemented to the public or a
wider audience, it’s already expected that it should work
properly.
5. Maintenance – with the software properly implemented,
developers role in this software does not end there.
Instead, they will have to work reactively for this
software. Instead of looking for the problems in their
created software, developers will only be providing answers
to their problems.

rong>6. Termination – of course not all software will last
forever. Updates has to happen and there will be time that
drastic changes has to happen in a software that they have
to be scrapped altogether. Although there will be traces of
the previous software, the evolution of new coding language
or the adaptation of the same software to a different
platform will warrant termination to the original program.
SDLC has to follow steps faithfully. These steps suggest
what type of development software they are. Although they
follow almost the same stages, it’s the treatment of these
stages suggest what they can do. Developers on the other
hand should consider their own skills, their intended users
and the available resources to determine what model they
should be following for software development. This will
ensure they are creating something that they can control and
maintain at anytime of the day. With proper steps and
guidelines, a good software is ensured for the users.
