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 Life Cycle Process For Full Fledged Web Development Process

Software Development Life Cycle, commonly known as SDLC, is a predefined set of rules and methodologies opted by web development services company,used to develop, manage and maintain information structure, required to improve the quality of the software design and development process.

Next the phase cones for software coding where the application logic for the software functionalities and user interface are developed. All the coding are written in very strict accordance with the coding standards followed by the industry. The codes are developed in a way to save the system resources and optimize the system efficiency.

System Deployment:
In the very next phase of deployment at web development company,the final system sets live at the locations, it’s meant to be implemented at. The phase decides the shortcomings of the entire software installed and suggests recommendations to accommodate the changes that occurs during the post implementation period.

System Maintenance:
During the system maintenance phase, a number of things about the web application development are taken into the consideration including:

  • Changes required in the system
  • Correction of any sort
  • Some required additions
  • Computer platform adjustments

Software Development Life Cycle – Basic Steps Leading to A Strong Product

After realizing and experiencing the alluring advantages of outsourcing, more and more companies are getting inclined towards outsourcing software development projects to major offshore destinations. However, having an in-depth knowledge of software development life cycle becomes a priority task for not only the service provider software development company but also the client to keep a check on the project progress throughout the software development.

Software development is an intricate process that requires a lot of planning, implementation and testing. You can not develop perfect software with full functionality unless it passes all the tests and quality analysis. So, companies should keep a check on SDLC while experiencing software development outsourcing, a company No software is perfect and in full functionality unless it overcomes all the tests.

A software development company put special emphasis on SDLC to produce the most effective, functional and mission critical software that can help one’s business in a long run. The software development life cycle (SDLC) is a pre-set framework that is used by all software development companies for through understanding and developing effective information systems and software.

Though software development life cycle can have many versions and each version carries its own plus points and minus points, but all version have same steps or activities that are discussed below;.

Feasibility

First of all, the project is checked for its feasibility if it should get the go-ahead. If the project is to proceed, then a project plan is thought out together with the budget estimates for future stages of development.

Requirement Analysis and Design

After testing the feasibility of the project, system or software requirements are gathered. Business analysts perform a thorough study and analysis of the business needs of the organization and the market trends. Necessary changes are proposed. From interface design to data design, every program is discussed in this stage to keep the software of high level design.

This phase considers the overall structure of the software and defines the strategy for its development. That’s requirement analysis and design phase is believed to be the most critical part of software development life cycle. Any flaw in this phase may prove very expensive for further stages of life cycle. In simple words, this phase considers the logical system of the product.

Code generation and Implementation

This phase involves the code translation of the well-thought design. Desired programs are created using a conventional programming language and with the help of programming tools like Compilers, Interpreters, Debuggers. The code is generated using various high level programming languages like C, C++, Pascal, Java, etc.

Testing and Quality Assurance

Apart from requirement analysis, testing is another crucial stage of SDLC that decides the effectiveness and functionality of the product. This phase unravels the bugs and errors of the system. Initially the individual modules of programs are tested separately which is followed by testing of the system as a whole. The system testing includes the integration testing to check whether the interfaces between modules are working properly, Volume testing to ensure the capability of the system to work on an intended platform with the expected load of data, and acceptance testing to check whether the system does what the user needs.

Maintenance and Support

Software system maintenance is an inevitable need. It undergoes various changes once it is delivered to the client. Software development should be flexible enough to inculcate required changes with time and according to changing business needs. Inevitably the system will need maintenance. Software may undergo certain changes once it is delivered to the customer. There are many reasons for the change. Change could happen because of some unexpected input values into the system. In addition, the changes in the system could directly affect the software operations. Therefore, the software should be developed in order to accommodate changes that could happen during the post implementation period.

Each and every stage of SDLC carries its own importance and plays a key role in success of any software development project.
