What is a Software Development Life Cycle?


The process of developing a software is not difficult to understand. The process of SDLC goes like this:

Gathering and then analyzing the prerequisites to develop a software
Designing of the software
Html coding or programming
Testing the software
Maintaining the software
Gathering and then Analyzing the prerequisites to develop a Software

This is the initial phase. Like starting any business, beginning work on a new software requires a plan. The planning phase should include the project administrators, stakeholders and even some senior software developers. No matter how professional or for how long the software development company has been operating, the planning is not an easy phase to follow. Although, it would take less time for experts to plan a new project and then to start working on it but still there will be some questions that have to always be answered before taking on any project. Following are some questions, which needs answers before taking on the project:

That will be using the software?
How they will be deploying it?
What is the mandatory data to input?
What will be the output of the input data?
What is the aim?
What skills are required? Will there be a need to hire new personnel or the current staff have the right skills and the capacity to work on this new project?
Find their answers. Is the project worth it? Good analysis is required here. There will be more questions that need to be answered before taking on this new project. All the work is documented for future reference.

Designing of the Software

Now comes the second phase, the designing of the software. On the basis of the documentation and the link between the first phase, the machine and the software is given a design. From this, the developers comes to know the prerequisites of the hardware and system required to complete their new project. This phase will also define the machine buildings. The designing phase will set the prerequisites for the next step.

Html coding or Programming

Here comes the role of the software developers. The machine design documents are now divided into adventures and the developers now start their job. This is going to be the at best phase of all. Programming is done here and it’s really known to all that programming isn’t an easy job. It takes sufficient time, expertise and patience. Once done, the software developer sends their work to the tester.

Testing the software

When in the production business, the standard of the product is always administered and tested. So is the case with a software development. When the html coding is done, the software developer sends their work to the Software Quality Assurance department /personnel. They will forget the work of the software developers. The software quality assurance or the SQA for short will appear for bugs and test the software. The test will be made per the prerequisites and the guidelines mentioned in the requirements document. Unit testing, integration testing, system testing, acceptance testing is done by the SQA and if found deviations or errors, it’s repaid to the software developer. The procedures will keeps on repeating themselves prior to the software is bugs free and ready to deploy.

Deployment of the Software

On successful end of the software and the testing, it is delivered to the concerned client or is available to the public.

Maintaining the software

Only the non-serious professionals or the ones not happy to carry on their business will not look back to their software but the serious developers will. Every software needs updating and maintenance. Whenever the software encounters some troubles, the software developing company will be there to fix it.
