Software
development life cycle or software development process is a framework used to
design, develop and test software. In this process, tasks are defined that have
to be performed at each stage of the software development lifecycle. The end
result of a software development process is creating software with the lowest
cost in the shortest span that is of the highest quality. Though there are many
companies that deal with software
development in Hyderabad you have to choose the best company that
understands your needs exactly. Every software development goes through few
stages that are vital to make the software successful.
Identification
of requirement: The analysis of who uses the product, for what purpose, how it
is used, what are going to be the inputs and what output is desired is the key
to create a satisfactory product. This is the first phase in software
development where the key data is gathered from the inputs of all the parties
concerned like stakeholders, the IT
consultants, sales team and the end users of the product. After all the information
is gathered and analyzed, it is also studied if developing software with these
requirements is possible.
Design: From
the requirement specifications arrived at in the first phase, a system design
is prepared that facilitates in defining the hardware and system requirements
for the overall design architecture. This system design is reviewed by all the
stakeholders and feedback is given. Failure to incorporate the stakeholders’
inputs at this phase may result in various troubles from costing issues to
project failure.
Building
software: When a perfect plan is ready through the previous phases with all the
details required the next phase is the one where the actual coding is done and
software is built. For the IT
consultants, this is the main focus area and it is the longest phase of the
software development process.
Testing: Once
the code is developed it has to be tested to check if it is meeting the initial
requirements and is a perfect solution addressing the needs gathered during the
first phase. If any defects or deficiencies are found, those issues are fixed
at this stage until the product meets the original requirement specifications.
Two types of testing are done at this stage – functional and non-functional.
Functional testing includes unit testing, integration testing etc.
Non-functional testing includes reliability testing, usability testing etc.
Deployment:
This is the phase where the software is deployed to the customer or end user.
This is usually done in a limited way initially to get feedback from the end
users regarding the performance of the product which is beta testing. Depending
on the feedback, adjustments are made to the product in case they any bugs are
caught. Then the software is finally deployed.
Maintenance:
When the final deployment is done and the customers start using the software
then, different issues arise and need to be solved in time with the help of IT support. Also, with time, situations
change and software needs to be updated to meet the changing conditions. This
process of taking care of issues arising for developed software by providing IT support is the phase of maintenance.
