Seven steps for Planned Maintenance (Keikaku-Hozen)

1. Support Autonomous maintenance
2. Learn and understand the equipment failures
   • Implement root cause analysis
3. Correct weaknesses of the equipment
4. Educate Operators in general inspections and develop standards for inspections
5. Establish Periodic Maintenance
   • Implement frequency of maintenance inspections
   • Time Based Maintenance (TBM)
6. Implement Predictive Maintenance System
   • Introduce diagnostic technology and learn failure behavior based on alpha and beta values
   • Condition Based Maintenance (CBM)
7. Optimize Planned Maintenance system
   • Establish Corrective Maintenance

Types of maintenance

1. Periodic Maintenance (Time based maintenance)
2. Predictive Maintenance (Condition based maintenance)
3. Breakdown Maintenance
4. Corrective Maintenance
