The Software Development Life Cycle (SDLC) is a structured approach to software development that outlines the stages involved in creating software. It provides a systematic process for planning, creating, testing, and deploying an information system. Here’s a breakdown of the typical phases in the SDLC:
1. Planning: This is the initial phase where the project's objectives, scope, and feasibility are defined. It involves gathering requirements, setting timelines, and allocating resources. The goal is to outline a clear plan for the development process.
2. Analysis: In this phase, detailed requirements are gathered and analyzed. Stakeholders and end-users provide input on what they need from the software. The requirements are documented and analyzed to ensure they are clear and achievable.
3. Design: The design phase involves creating the architecture of the software. This includes defining the system's structure, interfaces, and data models. The goal is to produce detailed design specifications that will guide the development phase.
4. Implementation: Also known as coding or development, this phase involves writing the actual code based on the design specifications. Developers create the software, integrate various components, and prepare it for testing.

5. Testing: Once the software is developed, it undergoes rigorous testing to identify and fix bugs or issues. This phase ensures that the software meets the requirements and performs as expected.
6. Deployment: After successful testing, the software is deployed to the production environment. It becomes available for end-users, and any necessary installation or configuration is performed.
7. Maintenance: Post-deployment, the software enters the maintenance phase. This involves providing support, fixing any issues that arise, and making updates or improvements based on user feedback and changing requirements.
Different SDLC models, such as Waterfall, Agile, Spiral, and DevOps, offer various approaches to managing these phases. Each model has its own set of practices and is chosen based on the project requirements, complexity, and goals.
