What are the four phases of system development in the SDLC?

• A. Testing, execution, modification, and support
• B. Planning, analysis, design, and implementation
• C. Research, coding, deployment, and feedback
• D. Initiation, execution, monitoring, and closure

Answer: (B)

The four phases of system development in the Systems Development Life Cycle (SDLC) are correctly identified as planning, analysis, design, and implementation. In the planning phase, the project's objectives and scope are defined, along with a feasibility study to evaluate the project's viability. This sets the foundation for how the project will progress. The analysis phase involves gathering requirements from stakeholders, which helps in understanding what the system needs to achieve. During this phase, analysts conduct a detailed examination of current systems and processes to find areas for improvement. In the design phase, the system’s architecture and specifications are created based on the requirements gathered earlier. This includes creating models and prototypes that outline how the system will function and what technologies will be used. Finally, in the implementation phase, the planned system is developed and deployed. This phase entails actual coding and integration of the system into the existing environment, followed by user training and support to ensure smooth adoption. The other choices mentioned do not accurately represent the conventional phases of the SDLC, as they include terms and steps that do not align with the widely accepted framework in system development.
