ANSWER

The SDLC is a structured process used by software developers to design, develop, test, and deploy software applications. There are various models and methodologies for SDLC, but I’ll describe a common phased approach:

1. Planning:
   • In this initial phase, project stakeholders define the software’s purpose, scope, and objectives.
   • A feasibility study is often conducted to assess the project’s viability.
   • A project plan is created, outlining tasks, timelines, resources, and budgets.
2. Requirements Analysis:
   • This phase involves gathering and documenting detailed requirements from end-users and stakeholders.
   • Analysts and designers work closely to understand what the software should do and create functional specifications.
3. Design:
   • During the design phase, the high-level architecture of the software is defined.
   • Technical specifications are created, including data models, system architecture, and user interfaces.
4. Implementation (Coding):
   • Developers write the actual code based on the design specifications.
   • Code is reviewed, tested, and revised as needed to ensure it meets the requirements.
5. Testing:
   • The software undergoes comprehensive testing to identify and fix defects (bugs).
   • Testing includes unit testing, integration testing, system testing, and user acceptance testing (UAT).
6. Deployment:
   • Once the software is thoroughly tested and approved, it is deployed to a production environment.
   • This phase may also include data migration and user training.
7. Maintenance and Support:
   • After deployment, ongoing maintenance is required to address issues, apply updates, and make improvements.
   • Support is provided to assist users and resolve any problems that arise.
8. Evaluation and Feedback:
   • Periodically, the project is evaluated to assess its success and identify areas for improvement.
   • Feedback from users and stakeholders is collected and used to inform future updates and projects.

It’s important to note that there are iterative and agile approaches to SDLC as well, where development cycles are shorter, and changes can be made more flexibly throughout the process.

Each phase in the SDLC serves a specific purpose and contributes to the overall goal of delivering a high-quality software product that meets user needs and requirements. The exact steps and order may vary depending on the specific SDLC model being used and the project’s unique characteristics.
