The document provides an overview of Lean Production and related concepts. It discusses that Lean Production aims to eliminate waste in manufacturing through streamlining processes. It identifies seven types of waste - overproduction, defects, waiting, unnecessary inventory, unnecessary motion, overprocessing, and transport. It also outlines five principles and five pillars of Lean Manufacturing. Examples of Lean implementation at Toyota, Saskatchewan and Maruti Suzuki are provided. The document concludes with thanking the presentation creators.

1. What is Lean
Production?
• Lean production is a systematic manufacturing method
used for eliminating waste within the manufacturing
system. It takes into account the waste generated from
uneven workloads and overburden and then reduces
them in order to increase value and reduce costs.
• The word ”lean” in the term simply means no excess, so
lean production can be translated simply into minimal
waste manufacturing.

2. Types of wastes
OVERPRODUCTION
o Production ahead of demand.
DEFECTS
o The cost of defect production and the effort required to
monitor for defects.
2
WAITING
o Production interruptions or time spent waiting for the next
step of the production process.

3. Types of wastes
MOTION
o When people must move more than necessary for their
part of the production process. For example, moving
pieces between a remote bin and machine.
INVENTORY
o Stocks of finished goods or work in progress not being
processed.
3
TRANSPORT
o Excessive movement of materials, work in progress or
finished goods.
OVER PROCESSING
o Processing to compensate for poor design or production
processes.

4. 5 PRINCIPLES OF
LEAN
MANUFACTURING
4
1. Minimize waste by eliminating non-value-adding activities.
2. Make production process efficient and streamlined.
3. Use only necessary resources to meet customer
requirements.
4. Identify and remove waste in areas such as
overproduction, waiting, unnecessary motion,
overprocessing, excess inventory, unused talent, and defects.
1. Continuously improve processes to eliminate inefficiencie
2. Continuously identify and remove waste.
3. Believe in the possibility of continuous improvement.
4. Involve employees in continuous improvement efforts.
5. Create a culture of continuous improvement that empowe
employees.

5. 5
1. Recognize employees as a
valuable resource.
2. Emphasize the importance of
employee involvement and
engagement in the
improvement process.
3. Create a supportive and
respectful work environment.
4. Encourage employees to
share ideas and suggestions
for improvement.
Empower and engage
employees in the improvement
process.
5. Enable employees to make a
meaningful contribution to the
organization's success.
1. Strong emphasis on
customer satisfaction.
2. Focus on creating value for
the customer.
3. Understand customer needs
and expectations.
4. Deliver products that meet
customer requirements in a
timely and cost-effective
manner.
5. Provide products that meet
customer needs and
expectations.
6. Minimize waste and
maximize efficiency in the
production process.
1. Lean manufacturing focuses
on creating a smooth flow of
work and materials.
2. The goal is to minimize
bottlenecks and increase
efficiency.
3. Products should move
seamlessly from one stage of
production to the next.
4. Unnecessary delays,
interruptions, and waste should
be eliminated.
5. Careful planning and
coordination of production
processes are required.
6. Continuous improvement
efforts are necessary to identify
and address inefficiencies.

6. Advantages of Lean Production
1. Increased Efficiency : Lean production streamlines
processes and reduces waste, resulting in higher
productivity and lower costs.
2. Improved Quality : Lean focuses on continuous
improvement, leading to fewer defects and a better
customer experience.
3. Enhanced Flexibility : Lean production systems are
designed to be adaptive, allowing for quick responses to
changing market conditions and customer needs.
4. Better Employee Involvement : Lean production
empowers employees to identify and solve problems,
leading to increased job satisfaction and engagement.
5. Increased profitability : By reducing waste and
improving efficiency, Lean production can help increase
profitability for businesses.

7. Disadvantages of Lean Production
1. High Implementation Costs : Implementing a Lean
production system can be expensive, especially for
companies with established processes and
technologies.
2. Resistance to Change : Some employees may resist
change and resist the adoption of new processes and
technologies.
3. Difficulty in Sustaining Improvements : Maintaining
the improvements achieved through Lean production
requires ongoing effort and commitment from all levels
of the organization.
4. Requires High Levels of Discipline : Lean production
relies on strict adherence to processes and standards,
which may be difficult to achieve in some organizations.
5. Can be Difficult to Measure Success: Measuring the
success of Lean production can be difficult, as
improvements may not always be quantifiable or may
take time to become apparent.

10. Fixed-value method poka-
yoke
The fixed-value poka-yoke method involves warning a worker
when a specified number of actions has not been met. This
would be applicable in a situation where the number of actions
is clearly defined and each is critical to the end result of the
process.

11. WHAT IS SIX SIGMA?
Six Sigma is a data-driven problem-solving methodology. The focus is on process variations and emphasis is
given to customer satisfaction. Continuous process improvement with low defects is the goal of this method.
The Goal of Six Sigma:
Six Sigma looks to reduce waste and it defines a
defect as anything that doesn’t meet the
customer’s expectations. A Six Sigma company
will produce no more than 3.4 defects for every
million opportunities.Six Sigma is a structured
problem-solving methodology.
Problem-solving in Six Sigma is done using the
DMAIC framework.
There are five stages in this framework.
- Define
- Measure
- Analyze
- Improve

12. Difference between Lean vs Six sigma
20X title 12
The following are the major differences between lean
and six sigma
1. Lean is defined as a systematic way of banishing
waste from the systems of organization. Six
Sigma refers to a process in which a specified
quality is maintained in the product by following
certain steps in that direction.
2. The main concept of lean thinking is the removal
of waste while six sigma is centered towards the
elimination of variation in the processes.
3. The Lean was developed by Toyota whereas
Motorola introduced Six Sigma.

13. 4.Lean is flow focused but Six Sigma is problem focused.
5.The tools used by lean are based on visuals whereas
the tools used by six sigma are based on mathematics
and statistics.
6.Implementation of lean will result in uniformity in the
output of the process. On the other hand, implementation
of six sigma techniques will lead to the reduction of flow
time of the operations.
7.The aim of lean is to improve production by increasing
productivity. Conversely, Six Sigma aims at fulfilling
client’s requirements.
Difference between Lean vs Six sigma

14. Examples
Saskatchewan, the Toyota lean management system
is used in combination with a strategic management
and policy deployment system, called Hoshin Kanri ,
and daily visual management.
Daily visual management is an approach where staff
members take the time each day to evaluate their
progress using the key elements of daily huddles and
visibility walls.

15. MARUTI SUZUKI
Poka-yoke in Japanese means mistake-proofing and it is followed whole heartedly in the
lean manufacturing industry, not only in their land, but in India too.
And, Maruti Suzuki India (MSIL), the country’s largest passenger cars manufacturer is been
following the same system since its inception in 1984, in order to improve its productivity
and lesser defects in the products.
Lean, mean efficiency It is the implementation of lean manufacturing system at its vendors
-- based on what Maruti has in-house production systems -- based on Suzuki Motor Japan
and Toyota Quality Management (TQM), which means improving the productivity,
eliminating the waste and reducing the defects.
The company through implementing lean manufacturing systems has 720 projects
completed so far for productivity improvement, quality, inventory control and energy
conservation. MACE has worked with 146 tier-II vendors for overall improvement in
performance resulting in reduction in rejections from 10,933 to 1,180 products per month
and defect reduction from 432 to 146 per month.
