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.

Software Development And The Growing Cloud Based Server Trend

Working from your office or even remote location using cloud based computer systems are one of the most amazing growth areas for which software development companies are increasingly finding their services requested. Even a year ago when you mentioned handing over a company’s entire database, customer records or financial reports to a third party most people laughed. The very idea of a completely separate company who would control an organisation’s software systems and the storage of data was treated with great suspicion and derision.

Developments in the modern world move fast though and today the idea is all the time more popular one for many reasons. Software development service providers are undertaking greater responsibility for supply, production and management of business systems. Companies can now avail themselves of the latest technologies, at a fraction the cost of traditional IT sourcing methods and get the latest updates as soon as they are released.

The use of third party software systems that provide remote access services mean that there is no need to worry about purchasing hardware or software packages and there is an additional saving on space that normally computers and servers would require. The combination of cloud based systems and software as a service (SaaS), is seen as a way for companies to broaden their horizons without over stretching themselves financially. They can have access to up to date software developments, system upgrades and technical support from their web developers as and when required.

As alien a concept as this was a year or so ago, this is gradually becoming a recognised alternative for many businesses. It offers many practical program development solutions, is an effective cost cutting method and at the same time gives businesses direct access to systems developers who can create bespoke software services, database management and enhanced provision for clients.

Database Management facilities are the latest in database control that mean large scale providers are establishing large custom built data centres where vast amounts of information can be safely stored. This is then easily access through Saas systems, simply and when required. Leading security software developers have already constructed substantial cloud based storage facilities that allow for real time access, without the worry of on site security requirements. This is seen as a way for clients to have the highest possible level of security for their data with complete ease of access from anywhere in the world.

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.
