Software development life cycle (SDLC), also called as software life cycle and software process, is a process widely used in the development of software. It is also called as a software life cycle and software process.

There are four stages in software development life cycle. They are:

Requirements analysis

Requirement analysis is where you get to know the important requirements that you want for your software. It is the first and initial step and requires a lot of knowledge on software engineering to develop the right software.

Specification analysis

The specification analysis stage begins when the software engineer is able to figure out the deliverables. At this stage, the software is properly described and laid down for full understanding. The specification analysis is very important to make the external interfaces stable and well functioning.

Architectural analysis

Architectural analysis deals with the conceptual representation of the system. A well-drawn architecture makes certain that the software will meet all the necessary requirements enabling it to accommodate future requirements. This stage also addresses interfaces among the software system, other software products, and other hardware and host operating system.

Coding

The coding stage, which is the fourth step in software development, involves reducing the code to better understand it.

Testing

After the coding phase, the testing phase follows. Of all the stages, this is the most important because extensive testing is performed to make sure that software developers have perfectly coded the software system.

It is also important to properly document software development. Sometimes, this step is missed, which turn causes problems on future maintenance and addition of other programs. Likewise, it was also found out that some software programs fail because the users are not properly educated on how to use it properly. Indeed, training is an important aspect of software development life cycle because end users are given the chance to ask questions for developers to solve.

In its early days, software development only required a developer to write the code of software. Today, the process has become quite intricate and complicated since a host of architects, analysts, developers, programmers, testers, and users are being employed to create the system. For this reason, the SDLC has become very important, without which the software would surely fail or perform poorly.
