There are usually two design stages in SDLC. They are:
SDLC stages by taking example of EDP department SDLC stages by taking example of EDP department
feasiblity study, system design system instalation, users training, system operational and system maintenance
SDLC (?)
for gathering data and information.
SDLC is software development life cycle and system analysis & design is one of the step in the cycle. Other steps being: 1. Requirement analysis 2. System analysis & design 3. Coding 4. Testing 5. Installation & maintenance
1. Planning for an information system2. Feasibility Study (optional)3. Requirements Determination (gathering)4. Conceptual design5. Physical design and/or purchase and/or prototyping6. Conversion from current system to new/changed system7. Training8. Implementation9. Evolution for enhancements and maintenance
SDLC has both verification and validation activities where as STLC has only validation activity. Simply STLC is a part of SDLC
The five phases of the Software Development Life Cycle (SDLC) are: Requirements gathering, Planning, Design, Implementation, and Maintenance. These phases guide the development process from initial concept to final product delivery, ensuring a structured approach to software development. Each phase contributes to the overall success of the project by systematically managing tasks and resources.
the weakness of conventional system analysis and design methodology are ;it is rigid and flexible ;it takes to long to deliver a working software for the client ;it does not allow for changing system requirements during system development ;end user are poorly consulted in determining requirements with the sdlc ;it does not allow backtracking to previous stages as it is too much time consuming and costly

The stages of the ITIL framework that represent the revolving lifecycle stages of the hub and spoke design are: Service Strategy, Service Design, Service Transition, Service Operation, and Continual Service Improvement. These stages work together in a cyclical manner to ensure that IT services are planned, designed, delivered, and continuously improved to align with the organization's needs.
