The Software Development Life Cycle

What is the SDLC?

SDLC stands for Software Development Life
Cycle, is the framework used for software development for various
computer platforms. SDLC can help software developers in meeting the
many requirements of their clients. It is equally useful for maintaining
the cost-effectiveness of the software development program by keeping the
budget in check.

Phases of the Software Development Life Cycle

SDLC has been involved in the software
development industry for many years and is considered to be a standard in
its self. The SDLC involves a number of phases, all of
which play a key role in the development of the software. Explaining these phases
below:

The Project
Planning Phase This is basically a research
stage of the development lifecycle. It requires software developers to
conduct a preliminary study which helps them in assessing the practicality as
well as feasibility of the product. Once these studies have been conducted and
the costs have been estimated, they are given to the client for
review and approval.

Systems
Analysis Phase This stage needs the
software developers to review a list of requirements that has been provided by
the client. This phase is required in 3-ways.

1. a. Firstly, it helps software developers in identifying any
   requirements that they will not be able to meet.
2. b. Secondly, the software development firm can also check if their computer
   systems are capable enough to meet the requirements of
   the job or project.
3. c. Lastly, It allows software developers to break down the software
   development process into smaller processes. This way, smaller goals and
   milestone can be created to monitor progress in the future stages.

Systems
Design Phase In this section, various
functions of the solution along with other required information is
discussed and useful. Diagrams and charts of the project, laying down the
rules of the business, planning screen layouts, and defining other relevant
factors are part of the design phase.

Construction Phase
The construction phase is the application development phase. A team of
dedicated professional software architects set out to meeting the requirements
of the client. The building phase is usually broken down into further smaller
projects and each project is assigned to different teams for completion. This makes sure
that every aspect of the project gets equal attention. The goals are also
sub-divided into milestones to provide a view of progress so that the entire project can be
tracked with ease. The building phase also requires software developers to
maintain a dialogue with the client so that any hindrances in the
development project may be reported and any suggestions received.

Test Phase After the project has been
successfully developed; the software development firm scrutinizes it for shortcomings
or anomalies. Once the prototype has been approved by experts, it is ready to
be used by the customer and is delivered to them.

Installation
upon delivery, the software is ready to be
installed into the client's computer system. Software development firms are
are regularly responsbile for installing the developed
software to the businesses computer system. Once the application has been
installed, the client may start to use it with immediate
effect.

Support

However, the job of the software
development firm doesn't end here. The process needs good software
development firms to maintain a feedback with the client just in case the software
may develop a problem. In such cases, it is the duty of the software developer
to assist the customer how to solve the specific problem. In case the same
problem resurfaces again, the software is handed back to the programmers
for revision.
