We all know the worth of software in our daily life. They have now become a necessity and an essential tool to cope with our modern world. Whether it is Whats-app, Instagram, Gmail, websites, etc. and from the past few years, the software industry makes a great paradigm shift due to rapid advancements in the web industry.
The demand for software is tremendously rising which ultimately pushing software development organisations to develop high-end, robust, and reliable software.
And the software development life cycle is the process that’s made it possible.
You might be wondering, What is Software Development Life Cycle? How does it work in developing software? Well, here it is.
The software development life cycle (SDLC) is a well-organised process to develop any kind of software from scratch.
The development of software is divided and align into several phases.
Planning is the first and foremost step which serves as a blueprint for the software. During planning the objectives, nature, and scope of software are defined which assist developers to build the software accordingly.
An in-depth analysis is carried out for a better understanding of software requirements and goals. Moreover, if the organisation is already using the same sort of software then an alternate proposal is made to enhance it.
Although the planning phase aids you in various areas of software development like idealisation, requirements analysis, defining the primary objective, allocation of tasks, determining project constraints, etc.
Once the requirements and everything is figured out, then the developing phase will guide you towards end goals like, how to develop software, what tactics need to consider? How to fulfill the demand of an end product? How to achieve the desired result? What programming language is suitable for it?
This type of question is common and comes often in developer minds while working on a new project. Operations like development of code and database are also put through during the development phase.
The primary objective of developing phase is to meet demand, choose the right design approach, allocate the team, and communicate with third-party. In the meanwhile, the software is already begun to start taking shape day by day, and sooner it is completed.
After all, the software is ready but still there are chances of uncertainties present in the codes which need to be fixed by deploying and integrating them in the real-testing environment.
Different quality control methodologies are used to thoroughly test the software for detecting any kind of flaws, coding issues, bugs, and other technical errors present in it.
Testing requires vital efforts to determine the success of your software. When the software is successfully tested then it is ready to be delivered. However, like other phases, testing is also the most important and extensive process which determines the success rate of software.
Finally after countless hours of coding and dealing with nerve-wracking deadlines the software is ready to install into the IT infrastructure. Deploying of software into the live working environment is the final thing that is done by the developers and ownership of the software is transferred to the respective clients.
To ensure the continuity of the software is untouched by technical barriers, the software needs regular maintenance over a certain period. New enhancements and changes are introduced in software to keep it up to date with the latest advancements.
The maintenance defines the longevity of the software as it provides after-sale support, security audits, system upgrading, and many more.
The above-stated phases of the software development life cycle play a vital role in developing and keeping the software alive. The success ratio of software is directly linked to the output from each stage of SDLC, therefore the developer must master each stage to deliver power-packed software built according to user needs.
