what is system development life cycle

The System Development Life Cycle (SDLC) is a process used by organizations to develop and maintain information systems. The SDLC provides a structured and systematic approach to the development of information systems, from the initial planning and analysis phase through the design, implementation, testing, and maintenance phases.

The SDLC typically consists of the following phases:

• Planning and Analysis: This phase involves identifying the needs and requirements of the stakeholders, such as business users and customers, and defining the scope and goals of the project.

• Design: In this phase, the system design is developed, including the architecture, user interface, database design, and technical specifications.

• Implementation: This phase involves the actual development of the system, including writing code, testing, and debugging.

• Testing: This phase involves testing the system to ensure that it meets the specified requirements and is free of defects.

• Deployment: In this phase, the system is deployed to production, and made available to users.

• Maintenance: This phase involves ongoing support and maintenance of the system, including bug fixes, updates, and enhancements.

The SDLC provides a structured and systematic approach to system development, and helps organizations to manage the development process, ensure that systems are developed to meet the needs of stakeholders, and maintain high-quality systems over time. By following the SDLC, organizations can reduce the risk of developing systems that do not meet user needs, are difficult to maintain, or contain defects that affect system reliability and security.
