What is S/W Development Life Cycle (SDLC)?
The development, maintenance, and retirement of software systems are all handled systematically using the software development life cycle (SDLC). It defines the stages involved in the development of a software system, from initial planning and requirements gathering to deployment and maintenance.
There are several different models for the software development life cycle, including the Waterfall model, the Spiral model, the Agile model, and the Lean model. Each model has its own set of phases and activities, but they all follow a similar overall process.
The general phases of the software development life cycle include:
- Planning: This phase involves gathering and documenting the requirements for the software system, as well as creating a project plan that outlines the tasks and resources needed to complete the project.
- Analysis: In order to assess the project’s viability and identify any potential risks or problems, this step entails evaluating and assessing the requirements.
- Design: This phase involves creating a detailed design of the software system, including the overall architecture and the specific components that make up the system.
- Implementation: This phase involves writing the code that makes up the software system and integrating the various components.
- Testing: This phase involves verifying that the software system functions as intended and meets the defined requirements.
- Deployment: This phase involves installing the software system in its production environment and making it available to users.
- Maintenance: This phase involves fixing bugs, making updates to the software system, and providing support to users as needed.
The iterative nature of the software development life cycle allows for ongoing improvement and evolution as the software system develops and evolves over time.
