Software development is a
complex process. Depending on the scope of the project, it can take months to years to
see a project through to completion. You are not finished with an application when it is
released, however. The development of applications goes through a life cycle that
includes product conception, architecture, and testing. Taking this life cycle into account
allows developers to consider every aspect of a potential application before starting
development. Understand the software development life cycle will help you create a
product that is both functional and targeted to your audience.
The first part of the software development life cycle (SDLC) is the requirements
definition. In this stage, you will need to outline exactly what your product is designed to
do, then figure out what it will take to deliver the product. You will need to consider not
just your developers, but also your security, infrastructure, networking, marketing, staffing
and support. You will need to have every piece of the puzzle in order to deliver a polished
final product. Try to cover every single aspect so that you can meet the expectations of
your users.
The next component of the SDLC is the actual architecture of the product. Here is where
you create your blueprint and figure out what you need in order to develop or run the
software. You will need to choose which tools you will use in the development process
as well as considering the needs of end-users. Although this would seem like a logical
first step in the software development process, ignoring the requirements can be a fatal
mistake. The requirements will dictate the scope of your project, while the architecture
will dictate the actual design.
The final part of the SDLC is testing. This is an extremely important step if you want to
deliver a product that works as it should. You should make sure to test the ability of the
product to perform as it was intended to be used. Do not perform QA testing in a vacuum
or you could end up missing critical flaws in your software. Also perform tests with a
wide variety of variables including various operating systems, network speeds, and
computer specifications. Your testers should essentially use the product as they
normally would while looking for bugs, design flaws, and incompatibilities. You will need
to focus on every step of the Software development life cycle if you want your product to succeed.
