This document provides an overview of total quality management approaches and improvement strategies. It discusses four improvement strategies: repair, refinement, renovation, and reinvention. It also outlines quality improvement frameworks like Kaizen, Six Sigma, and benchmarking. Key aspects of Kaizen are explained, including its focus on continual small improvements rather than large changes. The 5S methodology for organizing and standardizing the workplace is described. Total productive maintenance aims to keep equipment in top condition through cooperation between maintenance and production teams. Overall equipment effectiveness is a metric that measures availability, performance efficiency, and quality rate to monitor losses and improvement opportunities.
3. IMPROVEMENT STRATEGIES
REPAIR:
“Anything broken must be fixed so that it functions as
designed.”
Strategies divided into two levels:
1. Temporary or Short- term measure
2. Permanent measure
REFINEMENT:
“Activities that continually improve a process that is not
broken.”
Refinement improves efficiency and effectiveness.
RENOVATION:
“Strategy results in major or breakthrough improvement.”
Innovation & technological advancement are key factors in this
approach.
REINVENTION (RE-ENGINEERING):
“Reinvention begins by imagining that the previous condition
does not exist; A clean sheet of paper”

6. WHICH QUALITY APPROACH?
Continuous (i.e., Non–Stop) or
Continual (i.e., Recurring often
improvement frameworks)
– KaiZen
– Six–Sigma
– Benchmarking
7. KaiZen
“Kai” Change; “Zen” Better
Kaizen Make it Better (Improvement)
KaiZen is a System of accumulated improvement.
The main purpose of Kaizen is to evolve total employee participation and
it also helps in building capable work force for an organization
The results of Kaizen are not very drastic but incremental that’s why
continuous improvement leads to accumulated improvement.
Kaizen is a process-oriented thinking and not result oriented thinking:
PROCESS ORIENTED RESULT ORIENTED
Self discipline
Time management
Skill Management
Participation & involvement
Communication
Morale
I don’t care, you get it done just
give me one result

9. 10 Hints for doing successful KaiZen
1. No Excuses: Don’t make excuses… Don’t accept
excuses…Explanations are often still excuses (if you have
time to makeup excuses, you have time to think of
improvement ideas).
2. Don’t be a concrete head: Throughout traditional concepts…
Think how a new method can work, not how it won’t.
3. Do Kaizen by getting your hands dirty on the shop floor
4. Quick & Crude is better than slow and elegant: Don’t seek
perfection… 50% improvement rate is as long as it is done
on the spot.
5. Produce Actual Improvement
6. Implement Kaizen Newspaper items as committed: Don’t Put
of kaizen until tomorrow.
10. 10 Hints for doing successful KaiZen
7. Do Kaizen by adopting ideas of workers: Put yourself in the
worker’s position … The idea of 10 people are better than
the knowledge of one.
8. Do Kaizen without spending lots of money: Many small
improvements add up to big results … Implement quickly
with less risk.
9. Don’t overlook even the smallest waste (Muda): Over
production, delay, transportation, processing, inventory, etc.
10. Document results on target progress report: Document and
report results at regular report outs. Fill in the condition
even if there has been no change.
13. KaiZen : 5S
5S movement is a determination to
ORGANIZE WORK PLACE, To Keep It
Neat, TO CLEAN, TO MAINTAIN THE
DISCIPLINE to do a good job.
Japanese concept for house keeping
– Sort (Seiri)
– Straighten (Seiton)
– Shine (Seiso)
– Standardize (Seiketsu)
– Sustain (Shitsuke)
14. Decide what is needed and what is not,
and dispose of all items that are not necessary

be in car parking area?

15. 5 S PRINCIPLES
2 STRAIGHTEN

all necessary items so that they can be easily
found and used when needed.

3 SHINE / SWEEPING
Maintain a clean worksite at all times in order
to make work easier, safer, healthier and more
satisfying

4 STANDARDIZE
Continuously keep work

5 SUSTAIN / SELF-DISCIPLINE
Make it habit to engaging 5S activities
daily basis by establishing standards.

5 Contribute in work management
Create clean, healthy & safe working environment1

19. TOTAL PRODUCTIVE MAINTENANCE
Total Productive Maintenance (TPM) is keeping the current
plant and equipment at its highest productive level through
cooperation of all areas of the organization.
Generally, the first task is to break down the traditional
barriers between maintenance and production personnel so
they are working together.
TOTAL: All encompassing by maintenance and production
individuals working together.
PRODUCTIVE: Production of goods and services that
meet or exceed customers’ expectation.
MAINTENANCE: Keeping equipment and plant in as good
as or better than the original condition at all times.
20. TOTAL PRODUCTIVE MAINTENANCE
The Overall goals of TPM are:
1. Maintaining and improving equipment capacity
2. Maintaining equipment for life
3. Using support from all areas of the operation
4. Encouraging input from all employees
5. Using teams for continuous improvement
Successful TPM results are:
1. Zero Unplanned downtime
2. Zero performance loss
3. Zero defects
4. Zero energy loss
5. Zero accidents
21. Overall Equipment Effectiveness (OEE)
Overall Equipment Effectiveness (OEE) provides a metric or measure to
continually monitor how effectively the equipment is performing and
where the losses are with the potential for improvement.
IMPROVEMENT NEEDS:
Six major loss areas need to be measured and tracked:
DOWNTIME LOSSES:
1. PLANNED:
a. Start–Ups
b. Shift changes
c. Coffee & lunch breaks
2. UN-PLANNED DOWNTIME:
a. Equipment breakdown
b. Changeovers
c. Lack of material
REDUCED SPEED LOSSES:
3. IDLING AND MAJOR STOPPAGES
4. SLOW DOWNS
POOR QUALITY LOSSES:
5. IDLING AND MAJOR STOPPAGES
6. SLOW DOWNS
22. OEE … (Cont…)
These losses can be quantified into three metrics and can be summarized into one
equipment effectiveness metric.
Downtime losses are measured by EQUIPMENT AVAILABILITY using
the equation:
A = (T / P) X 100
Where:
A = Availability
T = Operating Time (P – D)
P = Planned Operating Time
D = Downtime
Reduced Speed Losses are measured by tracking PERFORMANCE
EFFICIENCY using the equation:
E = (C X N/ T) X 100
Where:
E = Performance Efficiency
C = Theoretical Cycle Time
N = Processes Amount (Quantity)
Poor Quality Losses are measured by tracking the RATE OF QUALITY
PRODUCTS produced using the equation:
R = (N – Q/ N) X 100
Where:
R = Rate of Quality Products
N = Processed amount (Quantity)
Q = Non–conformities
23. OEE … (Cont…)
BENCHMARK:
Some of the literature suggests that world – class
firms have AVAILABILITY greater than 90%,
PERFORMANCE EFFICIENCY greater than 95%,
and a RATE OF QUALITY PRODUCTS greater than
99%.
Therefore, the OEE for world – class companies
should exceeds 85%.
OEE = A X E X R
24. OEE: EXAMPLE
Last week’s production numbers on machining center JL58 were as fellows:
Scheduled operation = 10 hours/day; 5 days/week
Manufacturing downtime due to meetings, material outages, trainings, breaks, and
so forth = 410 minutes / week
Maintenance downtime scheduled and equipment breakdown = 227 minutes/week
Theoretical (Standard) cycle time = 0.5 minutes/unit
Production for the week = 4450 units
Defective parts made = 15 units
P = (10 hours/day) X (5 days/week ) X (60 minutes/hour) = 3000 minutes/week
D = 410 minutes/week + 227 minutes/week = 637 minutes / week
T = (P – D) = 3000 – 637 = 2363 minutes
A = (T / P) X 100
= (2363 / 3000) X 100
= 78.8%
E = (C X N / T) X 100
= (0.5 X 4450 / 2363) X 100
= 94.2%
R = (N – Q / N) X 100
= (4450 – 15 / 4450) X 100
= 99.7%
OEE = A X E X R = 0.778 X 0.942 X 0.997 = 0.740
(74%)
NOTE:
The equipment availability should be improved to reach the goal of 85%
equipment effectiveness.
