Role of Maintenance

Predictable Plant Capacity Efficient Energy Use Maintenance and Availability Maintenance and Quality Maintenance and Equipment Life Time Maintenance and Energy Use Maintenance and Economy

Organizations’ Objectives include: Meet or exceed customer satisfaction Maximizing profit Meet deliveries Meet set targets Meet set safety standard Zero product defect

Does Maintenance affect these goals?

Role of Maintenance

Maintenance is the backbone of all successful enterprises and contributes to:

Improve Product Quality Reduce Costs Meet Set Targets Improve Utilization Improve Equipment Performance
