There are two types of maintenance strategy :
1. Corrective Maintenance
a. Breakdown
Equipment is maintained after breakdown. This maintenance strategy is the most expensive because production breakdown can makes your boss angry hahaha.... This strategy is good for cheap equipment e.g bulp lamp.
b. Detective
Inspections are conducted to check whether such equipment had failed, if it fails should be replace
2. Proactive Maintenance
a. Preventive
Equipment is maintained before break down occures
b. Predictive
Condition base monitoring

Usually maintenace was approximately 30-50 % of operational cost, depending on the type of industries and depends on how management views of a maintenance organization: cost centers, cost control or investment. If maintenance is considered as a cost center, usually made as small as possible with multiskilling mechanics. It's even better to understand the importance of maintenance positions in production, so dare to make an investment for the maintenace to keep production going.
There are five processes:
1. Planning
Planning is to ensure all the needs for maintenance work, ranging from taskcard, spares, tools, mechanical skills (electrical, mechanical, WELDER, etc.). The approximate time should be implemented.
2. Scheduling
Scheduling based on data from the planning, the scheduling should inform the operation when the execution of maintenance, and for how long. Then the request to spares and tools are needed. If necessary it must be reported to third-party services (contractors).
3. Execution
Execution is done by a mechanic who must be supervised.
4. Follow-up
Follow-up is defined as the act continued. If there are findings should be immediately incorporated into the system so that no time has elapsed, especially the needs of his spares. It is also necessary to include other data such as the use of spares, tools, man hour, skills into the system.
5. Analyze
Analyze should be done to make improvements, ranging from a simple thing like manhour whether in accordance with the planning, as well as spares and tools. Maybe there who do not need to be done or perhaps some need to be added. The most important is whether the results of such work in accordance with expectations, is there anything we can still improve, or can we just replace with another, more accurate techniques and so on. This phase is usually decided more than one period of implementation to determine whether we are on the right track.
