A complete insight on what into Software development lifecycle (SDLC)

Software development life cycle or otherwise known as SDLC is a process and proper way of developing new software from scratch. Software or Application development has come a long way since inception and this process is basically used by the software developing companies for testing and developing high-quality and user-friendly software. The development life cycle holds a detailed plan or map on how to design, plan, build, and maintain a specific type of software.

Here is what goes into the entire development process of a software –

As depicted by a software developer of the Best software development company, software development life cycle lets you plan, analyze, design, develop, test, integrate, and maintain. Completing the development cycle or process can be long and tedious. However, it provides a framework with a standard set of activities and ensures the correctness of the software being developed, and it contains a set of detailed plans on how to develop, replace, and maintain any software. SDLC helps you decrease project risk and enhances project development speed as well.

The SDLC process is divided into different phases-

1.       Requirement and planning

Requirement and planning analysis are the first step and is the most important fundamental stage of SDLC. This phase gives you a clear understanding of the potential of the entire project and the anticipated opportunities, any issues, and the directives of the project. During this phase of development, relevant information is collected from the client that will be fed into the software.

2.       Revaluation of requirements

On completion of the planning part, the next step is to define and evaluate each and every need of the software. It is done or conducted with the help of a software requirement specification or an SRS document. The evaluation check includes budgetary issues, legal issues, operation feasibility, technical details, and scheduling delivery.

3.       Designing the software

This phase initiates designing of the software as per the specific requirements. This phase of SDLC helps you get an impression of the software as the specifications turn into a design plan, also known as a design specification. This phase includes high-level designing (HLD), and low-level designing (LLD). Here all the information is gathered in the SRS document which is later in implemented system development.

4.       Developing or coding

Now comes the coding phase, and in this phase, the coders start building the entire software by writing codes using a chosen programming language. This phase is divided into several modules that are assigned to different coders. In a software development process, this is the longest phase and the coders are required to follow certain predefined coding guidelines as well. Here the coders use programming tools like compilers, debuggers, and interpreters for generating and implementing the code.

5.       Software testing

After the coding phase, comes the testing phase, where the software is installed or deployed. Now the software testing team can start testing different functionalities of the software. In this phase, the testers may find some bugs/defects, and they communicate with the developers for quality analysis or re-test. It is done until the newly built software is bug-free and works as per client requirements.

6.       Installation and maintenance

After proper testing of the software, it is ready to be deployed and released in relevant markets. The installation phase is completed only after receiving feedback from the project manager.

Now comes the maintenance phase, and once the software is deployed customers start using it. The maintenance phase in SDLC checks for any bugs, required updates, and adds some enhancing new features to the existing software.

As per the software developers of a software development company, software development life cycle is a systematic software building process that ensures the quality and creativeness of the newly built software. So, it is important to adhere to a specific software development lifecycle for the successful completion of any project.
