System Development Life Cycle (SDLC) in Software Engineering

Software development life cycle (SDLC) is a model used in the software engineering community to manage and control the phases of a project/software. SDLC has main four stages, which are planning, requirements analysis, design, and code review. Each stage requires different levels of effort from the team involved.

The SDLC consists of various stages. Each stage requires different skills and knowledge. The first three stages are planning, design, and development. The last three stages are testing deployment and maintenance.

Stage-1: Planning And Requirement Analysis
Stage-2: Defining Requirements
Stage-3: Designing Architecture
Stage-4: Developing Product
Stage-5: Product Testing and Integration
Stage-6: Deployment and Maintenance Of Product

The first stage, planning, involves identifying the requirements and designing the software. This stage is important because it determines the scope of the project and establishes the project timeline. The planning stage also determines the software technologies that will be used and the implementation methodology.

The next stage, requirement analysis, is where the software requirements are verified and clarified. Requirements can be clarified by generating prototypes or by asking questions of the business users.

The next stage, coding, is where the software is created using the chosen software technologies. This stage is dependent on the requirements analysis and the design stage. The coding stage also determines the project structure and the software development methodology.

The next stage, testing, is where the software is tested to ensure that it meets the specified requirements. The testing stage is important because it determines the quality of the final product. And the last stage is deployment and maintenance where the final product is deployed.

The SDLC is an important process that is used to develop software. The planning, requirement analysis, and coding stages are important because they determine the scope of the project and establish the project timeline.
