Software Development Lifecycle (SDLC)?
The SDLC or software development lifecycle is essentially a model or methodological process or phase followed by software developers and developers to develop an application or software. As a simplest expression, this is a process that consists of activities designed to design, create, test, install, and maintain software.
SDLC is often referred to as a software development process as it consists of all the tasks that need to be followed when developing an application or software. SDLC is followed by IT development companies to develop, modify, replace, or improve software performance. ISO / IEC 12207 is the international standard for SDLC, which ensures the high quality of newly developed software. It also helps IT developers improve the overall quality of their software development services.
What are the most important SDLC models followed by the IT industry?
A number of SDLS models are currently in the IT industry. Often referred to as "software development process models", all process models follow unique software development steps, ensuring the 100% success of development projects.
The most important software development lifecycle 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.
Advantages of Choosing the Right Software Development Lifecycle (SDLC) –
- Increased Product Quality
- Enhanced Development Speed
- Increased Customer Relationships
- Enhanced Monitoring and Control
- Reduced Project Risk
- Reduced Project Management
Stages of SDLC
Design and Requirement Analysis
SDLC. At this stage, customers, sales team, industry experts, marketing team, and survey reports are needed. After that, the leading business executives and developers of the software development company plan the project's approach and the development model.
by finalizing the design documentation specification (DDS), the product architecture is designed by an expert team. This architecture needs to rely on various parameters such as budget, time, robustness of product, risk analysis, and design modularity, and this is taken into account in the development.
Development  Effective development of software or applications begins at this stage. The engineers and developers team follows the coding guidelines set by the organization and use different tools for code generation. The programming code is generated based on the DDS documented details. Developers use programming languages that meet the different requirements.
At this stage, the final product passes through a predetermined test path where the product is defective or defective and then recorded by the developers. This section ensures that the final product meets the world's highest quality standards.
This section is the end product with the customer. Sometimes the software is integrated with the client's current application and database. All installation and integration work is carried out by expert software developers and developers.
Maintenance and Support Developers
provide full maintenance and technical support after the final product has been installed on the client platform
