Computer Science – System Development Cycle {SS2}

Computer Science SS2 Third Term

Week 1

Topic: System Development Cycle

System Development Cycle is the processor of developing software through business, needs, analysis, design, implementation and maintenance.

Stages of System Development Cycle

Description of System development cycle

Conceptual planning: This phase is the step one of any system’s life cycle. It is during this phase that you need to acquire or significantly enhance a system and identify its ability and cost, risks and various project planning approaches are defined.
Planning and requirement: This begins after the report has been defined and appropriate resources have been committed.
Design: This phase is the functional support and training requirement stage which is translated into preliminary and detailed designs. Decisions are made to address how the system will meet function requirement.
Development and testing: During this stage, systems are developed or acquired based on detailed design specification. The system is validated through a sequence of unit and integration performance, system and acceptance testing.
Implementation: During this phase, the new or enhanced system is installed in the production environment, users are trained, data is converted over to the sponsor and businesses processes are evaluated.
Operation and maintenance: The system becomes operational in this stage.
Disposition: This phase represents the end of the system’s life cycle. It provides for the systematic termination of a system to ensure that vital information is preserved for potential future access and reactivation.

Description of stages of system development cycle

Maintenance: The system is accessed to ensure it does not become obsolete.
Feasibility study: This is conducted to determine whether creating a new or improved system is a viable solution.
Analysis: The goal of this system is to determine where the problem of the system lies.
