Research about SDLC, discussing it's methodology, benefits and key stages.

 SDLC, or Software Development Life Cycle, is a structured approach to software development that involves several phases. The methodology is used to guide the development of software projects from initial planning and analysis to final deployment and maintenance. The following discussion will explore the benefits of using SDLC, its key stages, and provide Harvard references to support the discussion.

Methodology: SDLC is a process that guides the development of software projects through various phases. The methodology consists of six main stages: planning, analysis, design, development, testing, and maintenance. Each phase is designed to ensure that software is developed in a structured and efficient manner. The goal of SDLC is to produce high-quality software that meets the needs of the end-users and the business.

Benefits: SDLC offers several benefits to software development teams. First, it provides a structured approach to software development, which helps teams to manage the complexity of software projects. Second, it helps to ensure that the software meets the needs of the end-users and the business. Third, it facilitates communication and collaboration among team members, which can improve the quality of the software. Finally, it helps to manage risks associated with software development projects.

Key Stages:

1. Planning: In this stage, the goals and objectives of the project are defined, and a plan is created to achieve them. The project plan includes a timeline, budget, and resource allocation.

2. Analysis: In this stage, the requirements for the software are analyzed. This includes understanding the needs of the end-users, identifying the features required, and defining the technical requirements.

3. Design: In this stage, the software architecture is designed. This includes defining the software components, data models, and user interfaces.

4. Development: In this stage, the software is developed. This includes coding, testing, and debugging.

5. Testing: In this stage, the software is tested to ensure that it meets the requirements and functions correctly. This includes unit testing, integration testing, and system testing.

6. Maintenance: In this stage, the software is deployed, and ongoing maintenance is performed. This includes fixing bugs, adding new features, and updating the software to meet changing needs.
