Introduction to Software Development

Software is a part of the computer system which allows or enables the hardware to operate. Computer software can be classifies as system and application software.

System software includes the operating system and other utilities which help in the smooth functioning of the computer and other applications in it.

Application software includes computer programs and related documentation that accomplish end-user data processing tasks. These are software developed for the end users for tasks like production control, payroll, inventory, word processing etc.

Software Development

It is a series of processes systematically undertaken to improve a business through the use of computerized information system. Software development has two major components, Systems Analysis and Design.

Analysis specifies ‘what’ the system should do, that is it sets the objective and Design stated ‘how’ to accomplish this objective. System Analysis is the process of studying the current system by a set of procedures which help to gather and interpret facts, identify the problems and use this gathered facts to improve the current system. The process of developing a new system with detailed concentration on the technical and other specifications that will make the new system operational is system design.

Software Development Life Cycle (SDLC)

It is a sequence of events carried out by analysts, designers and users to develop and implement an information system. The activities are carried out in different stages. The phases are Preliminary investigation (feasibility study), Determination of system requirements (analysis), Design of system, Development of software, System testing, System Implementation, System Maintenance. In reality these phases can overlap.

Necessity of Software Development

It is a fact that information technology has made it easier for companies to handle their business. With the use of efficient computer applications, even the most difficult and complicated activities can be completed within a few minutes. It is possible to develop software which automates tasks which are needed to be performed on a daily basis. Some applications can reduce the most complex tasks and bring it to a bare minimum.

Why Do You Need Software Development?

There are varieties of software applications available in the market which can take care of your needs. They are published to satisfy the requirements of a large number of corporations and companies. They are generic so that various organizations can use them. However, they might not be good enough to meet your specific requirements. These software applications are meant to serve the requirements of all the users as a whole, and so they might not contain certain functions which your company needs.

They might even contain extra coding which makes it cumbersome to use the program. Your organization is probably using multiple applications to help your business. A piece of software needs to be compatible with the other ones that you are using. Incompatibility issues can delay your work and cause you to lose revenue. These issues could hamper the performance of your computer systems and lead to loss of productivity in your workforce.

Software development company can potentially save you from losing money on worthless things and help you increase the productivity. A software developer will design a program which takes into consideration the infrastructure and the demands of your company. The developed applications will contain only those functions that your company is in need of. The developers will provide you with a customized piece of software which can run smoothly in your computer systems. The overall efficiency of the organization is achievable through these customized pieces of software.

How Can Hiring A Software Developer Help?

A software developer comes with the expertise of creating a custom application to fulfill the functions that are required.

These developers will first create a plan for the software. They will find out what functions you expect the application to perform. They will then make a basic blueprint of how the application will need to perform in order to achieve the result that you desire. It may not always be possible to design an application which contains all the functions that you want. This may be caused due to restrictions in the budget or possibly due to the fact that the requirement itself is too vague to be implemented.

After creating a plan, the developers will move on to the designing stage. The platform on which the application will be developed and which computing language should be used, are going to be determined at this point of affairs. They will decide how to proceed with the programming. The developers might even create a prototype in order to see whether the design is feasible or not.

The implementation phase will begin after a detailed draft of the application design has been finalized. The source code and the program will be created during this phase. The application programming interface will be created by the developers in this phase along with the software documentation. The developers will also check the software as it is being developed for bugs and flaws.

The developer will hand you the customized software and install it in your systems after finalizing the software and removing the bugs. They can also help you when it comes to the maintenance of the software systems.

As the technologies of the computers evolve, there will be a need for Software development company who has best software developers. They will be able to make applications which can benefit from the new systems and technologies. A good software system can help you get the most out of your limited resources.

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.
