Software Development Life Cycle – Introduction Model Stages and Advantages

What is the Software Development Life Cycle (SDLC)?

SDLC or Software Development Life Cycle is essentially the process or phases of a model or methodology, which software engineers and developers follow in developing an application or software. In simpler words, it is a process consisting of a series of planned activities for planning, creating, testing, deploying and maintenance of software.

SDLC is often referred as software development process, as it consists of all tasks, which needs to be followed while developing an application or software. SDLC is followed within IT development companies to develop, alter, replace or enhance the performance of the software. ISO/IEC 12207 is an international standard for SDLC, which ensures high quality of the newly developed software. It also helps IT development companies in improving the overall quality of their software development services.

What are the major SDLC Models, followed in the IT Industry?

There are various SDLS models, which are currently followed in the IT Industry. Often referred as ‘Software Development Process Models’, all the process models follow unique software development steps, ensuring 100% success of the development projects.

The major software development life cycle models are-

  • Waterfall Model
  • Iterative Model
  • Spiral Model
  • V-Model
  • Big Bang Model

Other related models are Rapid Application Development (RAD), Prototype and Agile Models.

The advantages of choosing an appropriate Software Development Life Cycle (SDLC)-

  • Increased Product Quality
  • Increased Development Speed
  • Improved Client Relations
  • Improved Tracking & Control
  • Decreased Project Risks
  • Decreased Project Management Overhead

What are the different stages of SDLC?

Stage 1:

Planning and Requirement Analysis

This is the most important stage in the SDLC. This stage needs input from the customers, sales team, industry experts, a marketing team and their survey reports. After which, senior business managers and developers of a software development company plan the project approach and the development model.

Stage 2:

Designing

After the analysis of requirements and finalizing the Design Document Specification (DDS), the product architecture is designed by an expert team. This architecture has to stand upon various parameters such as budget, time, product robustness, risk assessment and design modularity, after which it is considered for the development.

Stage 3:

Development

The actual development of the software or application starts at this stage. The team of engineers and developers follow the coding guidelines set by the organization and use different tools for code generation. The programming code is generated as per the details documented in the DDS. The developers use different high level programming languages as per the requirement.

Stage 4:

Testing

In this stage, the final product goes through a pre-defined road of testing, where defects or bugs in the product are reported and then fixed by the developers. This stage ensures that the final product meets the highest quality standards, which are accepted worldwide.

Stage 5:

Deployment

At this stage, the final product is deployed at the client base. At times, the software is integrated with the client’s current application and database. All the deployment and integration works are done under the guidance of expert software engineers and developers.

Stage 6:

Maintenance & Support

Most of the reputed IT development companies also provide complete maintenance and technical support, post deployment of the final product at client base.

New Era Of Custom Software Development

To sustain in this world full of competition, business has to be very effective. The emergence of the New Era of Custom Software Development Company in India has an unyielding experience in development of Custom Solutions. Software Development Company systematically analyzes the business and product requirements, and delivers customized cost-competitive, scalable and vigorous solutions.

If the organizations, concentrates to take on custom software application for their business it helps solves other problem that is amount of money involved.

Outsourcing Software development projects to India helps in solving unique problems of the organizations as the company absolutely gels with the requirement of new or existing projects, including analysis, database design, coding, testing and implementation. Transparent project management and change management practices that accentuate customer communication at prearranged intervals through e-mail, teleconferencing and video conferencing guarantee that the customer and project delivery teams carry a consistent understanding of requirements and project status at all times. Custom Software development Companies in India instead of changing the business practices that are already streamlined, think that it makes perfect sense for a business to go for the tailor-made software. Custom software development is nothing but the software made as per the requirements of the client applicable for that particular business’s needs.

Owing to the increasing offshore demand of customization, Software Development Company has started focusing on “Mass Customization”. Mass Customization is a process that combines the low costs of mass production processes with the flexibility of individual customization. The advent of new interactive technology, “Internet”, allows customers to interact with a company and specify their unique requirements, which in turn are manufactured by mechanized systems. Software Development Company have top rank industry qualified software development professionals like project managers, software engineers and programmers, testers, designers and technical writers with exclusive skill sets for developing Custom Software’s. The Custom Software Developer specializes in developing an idea into software suggested by a specific customer.

The Software is specifically designed for a customer thus; it cannot be sold or given to other buyers. Client dedication is the approach. First, attention to the integrity and ethics a company demands because there is strong need of comfortable interaction. Second, understanding the business allows leading it to the next level. The aim is to perfect the services of the Software Development Companies to trim operational costs, improve quality and free internal resources for other purposes.

Processes Involved in Software Development Project

A software development process is a structure to be followed while developing a new software product. There are different types of process models having certain cycles or phases involving various kinds of activities.

Project Kick Off is defined as the initialization of a project. It is an initial plan or proposal describing the main functionality and procedure of a project. Project kick off also narrates the responsibility of the key members in a project, and also describes about the people who are in need of this project.In a nutshell, Project kick off is the method of producing a overall plan for a project at its initiation phase.

Requirement Gathering is usually the first part or segment of a software project. It is the initial stage of product development. In this stage, a thorough market analysis is performed in order to access the real demand of potential customers. Sales and marketing people are mainly involved in requirement gathering stage of a software project. Their analysis helps the developer to develop the software as per the current market demand.

Prototype Development is an important phase in a software development process. The developers first time develop the software as per their conceptual analysis and design with most likely material in this stage. Thus, a through evaluation of design, material, product structure is performed in this stage. Development is a very important stage of software process, where the software is being developed using agile methodology or traditional waterfall method. This step also consists of several sub steps. A traditional waterfall method is based on planning, where as agile methodology works on present feedback.

Software Testing is a pivotal step in any software development project. It determines the quality of software by several industry standard techniques. Software testing is a step to find out the existing bug in newly developed software. There are several testing methods are used named black box testing, white box testing, grey box testing and so on.

Production Roll Out is the next stage where the team of software developers works in full production deployment. In this phase, all of the conceptual designs are tested and modified or refined by implementing in a pilot project. During this phase, testing and other associated supportive activity also have an importance in order to validate the iterative cycles of production deployment.

Knowledge Transfer is another vital aspect of a software process. Knowledge transfer and training go hand by hand in a process. An assessment is needed to conduct among the key workers in a project ensuring their capability while undertaking a particular area of implementation in a software project. A training material is crafted under the guidance of the experts and approved after a through scrutiny. This quality training material is distributed to the key players in the project and the knowledge is transferred as per the project requirement in order to implement the knowledge in different modules of product development.

Post Deployment Software Support is another critical step in a software development process. It is almost essential to provide quality support for the newly implemented software and to trouble shoot the possible problems.
