Quick Summary

The system life cycle in information science is a structured process for developing and maintaining information systems. It involves six stages: feasibility study, system analysis, system design, programming and testing, installation, and operation and maintenance. This systematic approach ensures that systems align with long-term business plans and strategic initiatives, often involving cost-benefit analyses.1

Information science itself is a discipline focused on the processes of storing and transferring information, integrating concepts from library science, computer science, linguistics, and psychology. The system life cycle is a key methodology within this field for creating robust and effective information systems.21
