Study Notes

Types of System Maintenance

Corrective Maintenance focuses on fixing errors in an already operational system, aiming for a return to functionality post-error diagnosis.
Preventive Maintenance is carried out to avoid potential issues before they occur, increasing user satisfaction and reducing downtime.
Adaptive Maintenance adds enhancements to operational systems, improving usability within the constraints of the existing system setup.
Perfective Maintenance aims to enhance system efficiency, reliability, and maintainability, often encompassing significant changes or reengineering.

Key Aspects of System Maintenance

System failure represents the worst-case scenario in Corrective Maintenance, necessitating swift action for recovery and error correction.
The initiative for Preventive Maintenance typically comes from the IT department, highlighting its overlooked yet essential role.
Adaptive Maintenance often presents more complexity than new systems development due to the existing system's limitations.
Perfective Maintenance is most effective mid-life of a system when frequent updates can lead to decreased efficiency and increased maintenance challenges.
