What Is a Software Development Life Cycle?

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

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

  1. Gathering and then analyzing the requirements to develop a software
  2. Designing of the software
  3. Coding or programming
  4. Testing the software
  5. Deployment
  6. Maintaining the software

Gathering and Then Analyzing the Requirements to Develop a Software

This is the initial phase. Like starting any business, starting to work on a new software requires a plan. The planning phase will include the project managers, 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 must always be answered before taking on any project. Following are some questions, which needs answers before taking on the project:

  • Who will be using the software?
  • How they will be using it?
  • What is the required data to input?
  • What will be the output of the input data?
  • What is the purpose?
  • 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? A thorough 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 results of the first phase, the system and the software is given a design. From this, the developers comes to know the requirements of the hardware and system required to complete their new project. This phase will also define the system architecture. The designing phase will set the requirements for the next phase.

Coding or Programming

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

Testing the Software

When in the production business, the quality of the product is always monitored and tested. So is the case with a software development. When the coding is done, the software developer sends their work to the Software Quality Assurance department /personnel. They will overlook the work of the software developers. The software quality assurance or the SQA for short will look for bugs and test the software. The test will be made as per the requirements 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 sent back to the software developer. The procedures will keeps on repeating themselves until the software is bugs free and ready to deploy.

Deployment of the Software

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

Maintaining the Software

Only the non-serious professionals or the ones not willing 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.

SDLC follows a simple procedure and it doesn’t require you to be a businessperson to know all the phases of SDLC. Every software developer and software developing company knows it all. So when hiring a software developing company you can rest assure that the procedure will be done in a professional way and the best product will be delivered.

Custom Software Development – A Vital Business Resource

Custom software development is becoming more and more vital as a commerce tool for many different types of business, but what exactly is it, and how can it improve a company’s performance?

Custom software development specialists explore exactly what it is a company does – what the necessities of the company are on a day to day basis and what they need from their IT system in order to operate to their optimum. In order to perform efficient functionality, a company would ideally need its software to do exactly what they want it to. And that’s where custom software development really gets stuck in.

Off the shelf software packages work perfectly well for some businesses but they can also pose troubles for many users if the package is not specifically geared towards fulfilling a company’s everyday business needs. On the other hand, what is the point in installing software within a business which will never be touched and does not aid the functionality of a company?

This is a regular occurrence for many companies who use generically manufactured software as it is very common for software functions to be installed but never ever used. This slows down networks, and clogs up the memory of your computer systems which leads to inefficient performance, not just of your computer network but of the day to day running of a company.

This is where custom software development comes in. Even you are not experiencing noticeable IT problems, a custom software development expert can show your company examples of how similar businesses perform in comparison, and the inefficiencies of your IT system. This auditing service can be extremely beneficial and has proved a successful component of custom software development.

An efficient, easy to use software package will only improve a company’s performance, not only with the daily operations, but will also gain competitive advantages when working towards vital long term goals. Custom software development is a cost effective way of getting that competitive edge over rival businesses, especially in the current economic climate where gaining that all important new client is more important than ever before, with such fine margins proving costly as we battle through the recession.

Often with IT solutions, the proof is in the pudding, and this certainly is the case with custom software development as many businesses experience a noticeable improvement in performance almost immediately when introducing bespoke, tailor made software.

There are many custom software development companies specialising in designing and creating user specific, bespoke software packages that will make an immediate impact upon your business operations. By improving the resourcefulness of your computer network, the day to day operations of a business will be able to be implemented more quickly which will improve the long term running of a company no end.

It’s time to stop cutting corners by buying off the shelf software when there are experts, with impressive testimonies to back up their credentials in custom software development that can improve the performance of your company’s IT systems. A personal service can be offered to you, in order to create the perfect software platform that fits your business like a glove, so follow the herd as custom software development really can be the difference between success and failure in this ever competitive world of commerce.

o Systems Analysis and Design- This is the third phase in which, the software’s overall structure and its nuances are defined. Being in terms of the client/server technology, it requires a number of tiers for the package architecture, the database design, and the data structure design.

o Code Generation- This code generation is performed in a detailed manner, and can be easily accomplished without much difficulty. Programming tools used to generate the code are Compilers, Interpreters and Debuggers.

o Testing- In this phase testing is performed to check the quality and its functionality. Various testing methodologies are available to unravel the bugs.
