Outline stages of software development life cycle?

1. Planning: This stage involves defining the project scope, objectives, requirements, and constraints. It also involves creating a project plan, timeline, and budget.

2. Analysis: In this stage, the development team gathers and analyzes requirements from stakeholders, end-users, and other sources. This helps in understanding the needs and expectations of the end-users.

3. Design: The design stage involves creating a detailed technical design of the software based on the requirements gathered in the analysis stage. This includes designing the architecture, database structure, user interface, and other components of the software.

4. Implementation: In this stage, the development team starts coding the software based on the design specifications. This involves writing code, testing individual components, and integrating them into a working system.

5. Testing: The testing stage involves verifying that the software meets the requirements and functions correctly. This includes unit testing, integration testing, system testing, and user acceptance testing.

6. Deployment: Once the software has been tested and approved, it is deployed to the production environment. This involves installing the software on the end-users' systems and making it available for use.

7. Maintenance: The maintenance stage involves monitoring and supporting the software in the production environment. This includes fixing bugs, adding new features, and making updates as needed to ensure the software continues to meet the needs of the end-users.

Stages of the Software Development Life Cycle (SDLC)

1. Planning and Requirements Gathering:
- Define project goals and scope
- Gather and analyze user requirements
- Create and refine software specifications

2. Design:
- Develop high-level architectural design
- Create detailed technical designs, including user interfaces and data structures
- Implement design patterns and architecture principles

3. Implementation:
- Write and test individual software modules
- Integrate modules into a cohesive application
- Ensure code quality through unit testing and code reviews

4. Testing:
- Conduct various types of testing, including unit testing, integration testing, system testing, and user acceptance testing
- Identify and resolve defects
- Verify and validate software functionality

5. Deployment:
- Install and configure software on production systems
- Train end users and provide documentation
- Monitor system performance and user feedback

6. Maintenance:
- Fix bugs and resolve issues
- Enhance and improve software functionality
- Adapt to changing requirements and technology advancements

7. Retirement:
- End software development and support
- Archive software and documentation
- Evaluate the success of the project and lessons learned
