- Definition: The software development lifecycle (SDLC) is a process used by software development teams to plan, design, develop, test, deploy, and maintain software applications
- Phases: The SDLC typically consists of several phases, including requirements gathering, system design, coding, testing, deployment, and maintenance
- Requirements Gathering: In this phase, the team identifies and documents the software requirements, including functional and non-functional requirements
- System Design: During this phase, the team creates a high-level design that outlines the system architecture, components, and interfaces
- Coding: In this phase, the developers write the code based on the design specifications, following coding standards and best practices
- Testing: The testing phase involves various types of testing, such as unit testing, integration testing, system testing, and user acceptance testing, to ensure the software meets the requirements and functions correctly
- Deployment: Once the software passes all the tests, it is deployed to the production environment, making it available for end-users
- Maintenance: After deployment, the software requires ongoing maintenance, including bug fixes, updates, and enhancements, to ensure its optimal performance and functionality
- Iterative Approach: The SDLC is often iterative, meaning that each phase may be revisited and refined based on feedback and changes in requirements
- Documentation: Throughout the SDLC, documentation is crucial to capture the design decisions, code changes, test cases, and user manuals for future reference and knowledge transfer
