What is Maintenance Management?
Maintenance Management is the process of planning, organizing, directing, and
controlling maintenance activities to achieve organizational objectives.
Maintenance Management involves the coordination of resources, including personnel,
materials, and equipment, to ensure that maintenance activities are carried out
efficiently and effectively.
Maintenance Management includes tasks such as developing maintenance plans,
scheduling maintenance activities, managing maintenance budgets, and monitoring
maintenance performance.
Effective Maintenance Management can help organizations reduce downtime, extend
equipment life, increase safety, and improve overall operational performance.

Benefit: Increased equipment and system availability and reliability.
Example: A power plant's regular maintenance program minimizes unplanned downtime of its
equipment, ensuring a continuous supply of electricity to its customers.
Benefit: Improved safety in the workplace.
Example: A chemical plant implements a safety-focused maintenance program to minimize risks of
accidents, such as equipment failures or leaks, thereby reducing the chances of injuries to workers.
Benefit: Increased profitability through better asset utilization and reduced maintenance costs.
Example: A trucking company implements a maintenance program that minimizes repair and
replacement costs by conducting regular inspections and preventive maintenance, leading to higher
profitability through better asset utilization.
Benefit: Better decision-making through the use of maintenance data and analysis.
Example: An oil and gas company uses maintenance data analysis to identify patterns and predict
equipment failures, enabling them to schedule maintenance activities and optimize equipment usage
to minimize downtime and maintenance costs.
Objectives and Benefits Differences in Maintenance
Management:
Objectives:
Objectives refer to specific goals that
maintenance management aims to
achieve.
Objectives may include improving
equipment efficiency, reducing downtime
and maintenance costs, and increasing
safety in the workplace.
Objectives and benefits are related but
distinct concepts in maintenance
management.
Benefits:
Benefits are the positive outcomes or
results that maintenance management
achieves when it successfully achieves
its objectives.
Benefits may include increased
availability and reliability of equipment,
improved quality of products and
services, and increased profitability.
1.1.3DIFFERENTIATE TYPES OF
RESPONSIBILITIES/ROLES IN
MAINTENANCE MANAGEMENT
ORGANIZATION.
Types of responsibilities/roles:
Maintenance Manager: The maintenance manager is responsible for planning,
organizing, and managing the maintenance activities of an organization. They
oversee the work of maintenance supervisors, technicians, and engineers, and
ensure that maintenance activities are carried out effectively and efficiently.
Maintenance Supervisor: The maintenance supervisor is responsible for
managing and supervising the work of maintenance technicians and engineers.
They ensure that maintenance activities are carried out according to the
maintenance schedule and quality standards.
Maintenance Technician: The maintenance technician is responsible for
carrying out routine maintenance activities, troubleshooting equipment
problems, and performing repairs as needed. They may also be responsible for
conducting preventive maintenance activities and keeping maintenance records.
Types of responsibilities/roles:
Maintenance Engineer: The maintenance engineer is responsible for
designing and developing maintenance programs, conducting equipment
analyses, and identifying opportunities for improvement in the
maintenance process. They may also be responsible for developing
maintenance standards and procedures.
Maintenance Planner/Scheduler: The maintenance planner/scheduler is
responsible for developing maintenance schedules and plans,
coordinating maintenance activities with production schedules, and
ensuring that equipment downtime is minimized.

MAINTENANCE ORGANIZATION
1.2 CONSTRUCT THE TYPES OF MAINTENANCE COSTS
Sources of maintenance cost:
There are several sources of maintenance cost that organizations need to
consider when developing maintenance strategies. These sources
include:
Equipment failure: Equipment failure is one of the main
sources of maintenance cost. When equipment fails,
repairs or replacement must be carried out to bring the
equipment back to operational condition.
Preventive maintenance: Preventive maintenance
activities such as inspections, lubrication, and calibration
are carried out to prevent equipment failure. These
activities also incur maintenance costs.
Corrective maintenance: Corrective maintenance
activities such as repairs and replacements are carried out
to fix equipment failures. These activities incur
maintenance costs.
Predictive maintenance: Predictive maintenance activities
such as vibration analysis and oil analysis are carried out
to predict equipment failures before they occur. These
activities incur maintenance costs.
Spare parts inventory: Organizations need to maintain an
inventory of spare parts to carry out maintenance activities. The
cost of purchasing and storing spare parts is a source of
maintenance cost.
Laborcosts: The cost of laborto carry out maintenance activities is
a source of maintenance cost. This includes the cost of in- house
maintenance personnel as well as the cost of outsourced
maintenance services.
Maintenance management software: Maintenance management
software is used to manage maintenance activities and costs. The
cost of purchasing and maintaining this software is a source of
maintenance cost.
Cost Analysis Methods:
Cost analysis is an important aspect of maintenance management that involves
identifying, quantifying, and analyzingthe different costs associated with maintenance
activities. There are several cost analysis methods that can be used in maintenance
management, including:
Breakdownanalysis:Breakdownanalysisinvolves
