PLANNING AND CONDUCTING MAINTENANCE

Preventive Maintenance

• can be described as maintenance of equipment or systems before a fault occurs. It can be divided into two subgroups: Planned Maintenance and Conditioned-Based Maintenance.

​

PREVENTIVE MAINTENANCE

1. Planned Maintenance (PM)

• is any variety of scheduled maintenance to an object or item of equipment. Specifically, PM is a scheduled service visit carried out by a competent and suitable agent, to ensure that an item of equipment is operating correctly to avoid any unscheduled breakdown and downtime of equipment.

2. Condition Based Maintenance (CBM)

• is a maintenance strategy that uses the actual condition of the asset to decide what maintenance needs to be done. CBM dictates that maintenance should only be performed when certain indicators show decreasing performance or upcoming failure. Checking a machine for these indicators may include non-invasive measurements, visual inspection, performance data, and scheduled tests. Condition data can be gathered at certain intervals, or continuously.

IMPORTANCE OF MAINTENANCE IN COMPUTER SYSTEMS

• Regular maintenance of computer systems are both preventive and corrective are essential to ensure optimal performance, security, and longevity of devices.
• Preventive maintenance helps avoid potential issues by regularly checking, cleaning, and updating systems. It reduces the risk of hardware failure and software problems.
• Corrective maintenance, on the other hand, addresses issues after they occur, helping restore systems to working condition and minimizing downtime. Proper maintenance also enhances user productivity, protects data, and reduces long-term repair costs.

IMPORTANCE OF MAINTENANCE IN COMPUTER SYSTEMS

• The purpose of systematic inspection, detection, and correction of existing/ future problems is very important to maintain equipment/ facilities in satisfactory condition before it may cause major problems.
• Maintenance, including tests, measurements, adjustments, and parts replacement, performed specifically to prevent faults from occurring.

MAINTENANCE IS DIVIDED INTO TWO (2) GENERAL TYPES.

1. Preventive maintenance

• is given for maintaining equipment and facilities in satisfactory operating conditions to extend the life of the equipment.

2. Corrective maintenance

• is a task performed to identify, isolate, and rectify a fault so that the failed equipment or system can be restored to operational conditions within the tolerances or limits.

ACTIVITY – PROCESS QUESTIONS

• Why is maintenance important in extending the life of computer systems?
• Summarize the difference and benefits of both maintenance types.
