3. History :
This is an innovative Japanese concept.
Developed in 1951.
Nippondenso was the 1st company that
implemented TPM in 1960.
Based on these developments Nippondenso was
awarded the distinguished plant prize for developing
and implementing TPM, by the Japanese Institute
of Plant Engineers ( JIPE ).
This Nippondenso became the first company to
obtain the TPM certifications.
4. Introduction to TPM
• TPM is a continuous improvement strategy that covered all
aspects of an organization .
• TPM is a innovative Japanese concept.
• How ever the concept of preventive
maintenance was taken from USA
5. Total productive maintenance (TPM) originated in
Japan in 1971 as a method for improved machine
availability through better utilization of maintenance
and production resources.
TPM is a maintenance process developed for
improving productivity by making processes more
reliable and less wasteful.TPM is an extension of TQM.
The concept of ‘true’ TPM is that everyone from the
operator to top management is responsible for
maintenance activities.
Introduction
6.
7. Total Productive Maintenance (TPM) is a
method to achieve maximum equipment
effectiveness through employee
involvement
Management + Operators + Maintenance
What is TPM ?
8. What is TPM?
Total productive maintenance is a
maintenance program which involves a newly
defined concept for maintaining plant and
equipment.
Coupled with the right tools and training,
TPM equips the operator the necessary skills
to address mechanical or equipment
related issue.
Think about how to Increase production and
reduced cost by reducing or eliminating
loss, and this is the TPM.
9. TPM in three words :
Total = All individuals in the organization
working together.
Productive = production of goods that
meet or exceed customer’s
expectations.
Maintenance = keeping equipment and
plant in good condition at all
times.
10.
11. TPM was introduced to achieve the
following purposes
• Avoid wastage in a
quickly changing
economic environment.
• Producing goods without
reducing product quality.
• Reduce cost.
• Produce a low batch
quantity at the earliest
possible time.
• Goods send to customers
must be non defective.
12. Principles of TPM
Use Overall Equipment Effectiveness (OEE) as a compass for
success.
Improve existing planned maintenance systems.
Work toward zero losses
Providing training to upgrade operations and maintenance skills
Involve everyone and utilize cross-functional teamwork
13. Objectives of TPM
To markedly increase production while, at the same time,
increasing employee morale and job satisfaction.
To hold emergency and unscheduled maintenance to
minimum.
To create a lean organization with reduced cycle time
and improved operational efficiency.
Achieve zero defects, zero breakdown and zero
accidents in all functional areas of the organization.
Involve people in all level of organization for forming
different teams to reduce defects and self
maintenance.
14. Adoption of life cycle approach for improving the
overall performance of production equipment.
Improving productivity by highly motivated workers
which is achieved by job enlargement.
The use of voluntary small group activities for
identifying the cause of failure, possible plant and
equipment modification.

18. Types of maintenance
Breakdown Maintenance
It means that people waits until equipment fails
and repair it.
Such a thing could be used when the equipment
failure does not significantly affect the operation
or production or generate any significant loss
other than repair cost.
19. Types of maintenance
Preventive Maintenance
Preventive Maintenance is PERIODIC MAINTENANCE
that retains the condition of equipment and prevents failure
through the prevention of deterioration, periodic
inspection, and equipment condition diagnosis. PM
includes cleaning, inspection, lubrication and tightening.
Preventive Maintenance is further divided into Periodic
Maintenance and Predictive Maintenance.
Periodic Maintenance is time-based.
Predictive Maintenance is condition-based.
20. Types of maintenance
Corrective Maintenance
Corrective Maintenance improves
equipment and its components so that
preventive maintenance can be performed
reliably.
Equipment with a design weakness is
redesigned with corrective maintenance
to improve reliability or maintainability.
21. Types of maintenance
Maintenance Prevention
It indicates the design of a new equipment.
Weakness of current machines are sufficient studied
and are incorporated before a new equipment.
22. Stages in introduction of TPM
organization
STAGE A Preparatory Stage Step 1:Announcement by
management to all about
TPM introduction in the
organization
Step 2:Initial education and
propaganda for TPM
Step 3:Setting up TPM and
department committees
Step 4:Establishing the TPM
working system and target
Step 5:A master plan for
institutionalizing
STAGE B INTRODUCTION STAGE
STAGE C IMPLEMENTATION STAGE
STAGE D INSTITUTIONALISING STAGE
23. Stage A – Preparatory stage
Step 1:Announcement by management to all about
TPM introduction in the organization
Proper understanding, commitment and active
involvement of top management in needed for this step.
Senior management should have awareness
programmes, after which announcement is made to all.
24. Stage A – Preparatory stage
Step 2:Initial education and propaganda for TPM
Training is to be done based on the need.
Some need intensive training and some just an
awareness.
Take people who matters to place where TPM already
successfully implemented.
25. Stage A – Preparatory stage
Step 3:Setting up TPM and department
committees
TPM include improvement, autonomous
maintenance, quality maintenance etc., as part
of it.
when committees are set up it should take
care of all those needs.
26. Stage A – Preparatory stage
Step 4:Establishing the TPM working system and
target
Now each area is benchmarked and fix up a target
for achievement.
27. Stage A – Preparatory stage
Step 5:A master plan for institutionalizing
Implementation leading to institutionalizing wherein
TPM becomes an organizational culture.
28. Stage B – Introduction Stage
In this stage TPM is introduced.
TPM is introduced based on customer
requirements, quality of product, etc.
29. Stage C – Implementation stage
In this stage TPM is Implemented in organization.
In this stage EIGHT ACTIVITIES are carried out
which are called EIGHT PILLARS in the
development of TPM activity.
Four activity are for establishing the system for
production efficiency, one for initial control
system of new product and equipment, one for
improving the efficiency of administration and
are for control of safety, sanitation as working
environment.
30. Stage D – Institutionalizing Stage
This the final stage of introduction of TPM in
organization.
In this level, challenging level are think.
32. Pillars of TPM
PILLAR 1 - 5s
Japanese
Term
English
Translation
Equivalent ‘S’
term
SEIRI Organization Sort
SEITON Tidiness Systematize
SEISO Cleaning Sweep
SEIKETSU Standardization Standardize
SHITSUKE Discipline Self-discipline
33. Pillars of TPM
SEIRI – Sort Out
The first S focuses on eliminating unnecessary
items from the workplace.
An effective visual method to identify these unneeded
items is called Red Tagging.
A red tag is placed on all items not required to
complete your job. These items are then moved to a
central holding area.
This process is for evaluation of the red tag items.
34. SEITON – Systematize
Second S focuses on efficient and effective
storage methods and how to organize the work
area.
Strategies for effective Set In Order are painting
floors, outlining work areas and locations,
shadow boards, and modular shelving and
cabinets for needed items such as trash cans,
brooms, mop and buckets.
Pillars of TPM
35. Pillars of TPM
SEISO – Shine the workplace
Once you have eliminated the clutter and junk that
has been clogging your work areas and identified the
necessary items, the next step is to thoroughly clean
the work area.
Workers will also begin to notice changes in
equipment and facility location such as air, oil,
coolant leaks, fatigue, breakage, and
misalignment.
36. Pillars of TPM
SEIKETSU - Standardization
Now the first three S’s are implemented.
Use standard methods to keep Sort, Set In Order,
and Shine to a condition .
Allow your employees to participate in the
development of such standards.
37. Pillars of TPM
SHITSUKE – Self discipline
This is the most difficult S to implement and
achieve.
Maintain through empowerment, commitment,
and discipline .
Sustain focuses on defining a new status
quo and standard of work place
organization.
38. Pillars of TPM
PILLAR 2 - Autonomous Maintenance
This pillar is geared towards developing operators
to be able to take care of small maintenance tasks,
thus freeing up the skilled maintenance people to
spend time on more value added activity and

In this area focus is on to create a safe workplace and
surrounding area that is not damaged by our process
or procedures.
This pillar will play an active role in each of the other
pillars on a regular basis.
45. Pillars of TPM
PILLAR 8 - Office TPM
Office TPM must be followed to improve productivity, efficiency in the
administrative functions and identify and eliminate losses. This includes
analyzing processes and procedures towards increased office automation
Plans & Guidelines:
Providing awareness about office TPM to all support departments
Helping them to identify P, Q, C, D, S, M in each function in relation to plant
performance
Identify the scope for improvement in each function
Make up an activity board where progress is monitored on both sides - results
and actions along with Kaizen.
Fan out to cover all employees and circles in all functions.
46. Pillars of TPM
P Q C D S M in Office TPM :
P - Production output lost due to Material, Manpower productivity,
Production output lost due to want of tools.
Q - Mistakes in preparation of cheques, bills, invoices, payroll,
Customer returns/warranty attributable to BOPs,
Rejection/rework in BOP's/job work, Office area rework.
