🧩 Key Phases of Software Development

Most development follows a structured process called the Software Development Life Cycle (SDLC):

1. Requirement Analysis – Understanding what users or clients need.

2. Planning – Defining scope, resources, budget, and timeline.

3. Design – Creating system architecture, UI/UX designs, and database models.

4. Implementation (Coding) – Writing the actual code using programming languages like Python, Java, C#, etc.

5. Testing – Verifying that the software works correctly and fixing bugs.

6. Deployment – Releasing the software to users.

7. Maintenance – Updating and improving the software over time.

🛠️ Popular Software Development Methodologies

Different teams follow different approaches depending on the project type:

• Waterfall Model – Sequential, phase-by-phase approach.

• Agile Development – Iterative and collaborative; emphasizes flexibility (e.g., Scrum, Kanban).

• DevOps – Integrates development and operations for continuous delivery.

• Spiral Model – Combines design and prototyping in stages.
