Software Development

What is the Software Development Lifecycle?

A set of instructions for a computer to read and understand to perform a specific task is called Software. Software development is the process of using computer programming to develop software. This is not new to many, but the topic under consideration will be new to many. SDLC or Software Development Life Cycle, is the process of developing new software.

The software development process is not difficult to understand. The SDLC procedure goes like this:

Collect and then analyze requirements to develop software
Designing software
Coding or programming
Testing software
Deployment
Maintaining software

Collecting and Then Analyzing Requirements to Develop Software

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

Who will use the software?
How will they use it?
What data is required for input?
What will be the output of the input data?
What is the purpose?
What skills are required? Will there be a need to recruit new personnel or do current staff have the right skills and capacities to work on this new project?

Find their answers. Is the project worth it? A thorough analysis is required here. There will be more questions that need to be answered before taking on this new project. All work is documented for future reference.

Designing Software

Now comes the second stage, software design. Based on the documentation and the results of the first stage, the system and software are given a design. From here, the developers know the hardware and system requirements needed to complete their new project. This phase will also determine the system architecture. The design stage will determine the requirements for the next stage.

Coding or Programming

This is where the role of the software developer comes in. The system design document is now divided into modules and the developer is now getting to work. This will be the longest phase of all. Programming is done here and everyone knows that programming is not an easy job. It takes a lot of time, skill and patience. Once done, the software developers send their work to the testers.

Testing Software

When in the production business, product quality is always monitored and tested. Likewise with software development. When the coding is complete, the software developers submit their work to the Software Quality Assurance department/employee. They will ignore the work of software developers. Software quality assurance or SQA for short will look for bugs and test the software. The test will be conducted in accordance with the requirements and guidelines stated in the requirements document. Unit testing, integration testing, system testing, acceptance testing are done by SQA and if any deviations or errors are found, sent back to the software developer. This procedure will keep repeating until the software is bug free and ready to use.

Software Deployment

After successful completion of the software and testing, the software is delivered to the client concerned or made available to the public.

Maintaining Software

Only non-serious professionals or those who don’t want to run their business won’t look back on their software, but serious developers will. Every software needs updating and maintenance. Whenever the software encounters some problem, the software development company will be there to fix it.

SDLC follows a simple procedure and doesn’t require you to be a business person to know all phases of SDLC. Every software developer and software development company knows it all. So when hiring a software development company, you can rest assured that the procedure will be carried out professionally and that the best product will be delivered.
