This concept is central to the video's theme, explaining how companies can operate more efficiently.

💡Toyota Production System (TPS)

The Toyota Production System (TPS) is a manufacturing methodology developed by Toyota that focuses on just-in-time production and jidoka (automation with a human touch). TPS is the foundation of lean manufacturing, emphasizing continuous improvement and waste elimination. The script uses TPS to illustrate the origins and effectiveness of lean practices.

💡Waste

In lean manufacturing, waste refers to any action that consumes resources without adding value to the customer. Examples include overproduction, excess inventory, and unnecessary processing. The video discusses how identifying and eliminating waste is crucial to improving efficiency and customer satisfaction.

💡Value Stream Mapping (VSM)

Value Stream Mapping (VSM) is a lean tool used to collect data on the actual flow of physical elements and information in the production process. It helps identify areas of waste and opportunities for improvement. The script mentions VSM as a basic tool in lean manufacturing to optimize production flows.

💡5S

5S is a workplace organization method consisting of five steps: Sort, Set in order, Shine, Standardize, and Sustain. It aims to create a well-organized and orderly workplace, which is essential for maintaining efficiency and quality. The video highlights 5S as one of the fundamental tools of lean manufacturing.

💡Kaizen

Kaizen is a Japanese term meaning 'continuous improvement.' It involves all employees in the organization working towards constant, incremental improvements.

in today's episode

we'll talk about what is lean

manufacturing and what principles and

tools does it use

what does the lean concept have in

common with the toyota production system

which industries use the lean concept

what are the benefits for companies

using the lean concept

what is the easiest way to explain what

lean manufacturing

is it is a method of production

management that has been developed based

on the principles and tools of the

toyota production system

tps it assumes that the primary goal of

the company

should be to maximize value for the

customer while eliminating waste

overproduction excess inventory

processing

unnecessary traffic etc by the lean

standards

waste is any action that consumes

resources without adding value to the

customer

and that's also why the name lean fits

perfectly

lean production is more well lean than

the traditional mass production

because it uses less human labor

production space

or engineering work the term lean

manufacturing was proposed in 1988 by

john krafcik

who first used it as a term to describe

an alternative system to popular mass

production

in a publication entitled the triumph of

the lean production system

the concept was then popularized by a

group of scientists

james womack daniel jones and daniel

ruse after their publication of their

book

the machine that changed the world in

1990

in the book they introduce terms such as

lean manufacturing

lean production lean organization lean

enterprise the lean concept is common

nowadays

an extension of the concept of lean

manufacturing is lean management which

applies not only to production

but also the whole management and makes

all participants of the organization

interested in continuous cost reduction

increase in the quality level

and shortening the delivery time the

principles of lean manufacturing

include defining value for the customer

determining the value stream for each

product

creating a free flow of materials and

raw materials

implementing a pull system in the

customer supplier relationship

and continuous pursuit of perfection

the lean concept characterizes its

customers as a beginning

and endpoint which in simple terms means

optimization from the point of view of

customers needs

and not the internal capabilities of a

given company

the basic lean manufacturing tools are

value stream mapping vsm to collect data

on the actual flow of physical

elements and information 5s 5 steps

it is based on the assumption that

errors are caused by processes

not people kaizen continuous improvement

based on the belief that employee

commitment and their constant pursuit of

excellence

have a greater impact on the company's

development than significant but

sporadic improvements

all these tools should be implemented as

a comprehensive system

of interdependent and mutually

supportive practices

as it was mentioned at the beginning the

lean manufacturing concept refers mainly

to the toyota production system

and this is where its basic tools were

derived from

the toyota production system is based on

two concepts

jadoka and just in time jidoka is

simply put an automation with a human

touch

it is a method of quickly identifying

and correcting problems that could lead

to production defects

the concept of just in time is about

improving and coordinating

all production processes in such a way

as to produce only what the next process

requires

how does tps work the customer starts

the process by ordering a car at a

dealer

the toyota dealer issues a demand

through headquarters i.e

a kanban for a car and a car assembly

plan

the order is quickly implemented on the

production line according to the

heijunka principle

i.e level scheduling this means that the

manufactured products

and their quantity are balanced in such

a way as to meet the customer's

requirements

and to minimize the inventory the

assembly plant sends the kanban to the

component factory

in the factory turns to its suppliers

first the body of the car is created

followed by painting and assembly

only the parts ordered by the customer

in a pull system

are produced and delivered the finished

cars are transported by water

or land to a toyota dealer and then they

are delivered to a satisfied customer

the toyota production system assumes

that the car is to go smoothly through

the production line

this means that the right parts are

delivered to the right place

in the right time when they are needed

and in just enough quantity

to avoid stockpiling at the factory

by focusing on small production batches

and producing only what customers want

toyota has developed flexibility and

responsiveness to market needs

which has become an industry standard by

striving for continuous improvement

kaizen

toyota has achieved significantly

shorter times for changing production

dyes

and machine configurations than their

competitors

the ability of the toyota production

system to react quickly to new trends

makes it an ideal model in a dynamically

changing business environment

not only does toyota use the lean

manufacturing system

the concept is also used by such giants

as

ford parker hanafin john deere

caterpillar textron intel

kimberly clark corporation and nike

lean management principles outside of

the industry have been reflected in

various other sectors

in the service sectors lean service

including banking and financial services

hotels restaurants and air transport

in healthcare lean healthcare in

logistics

lean logistics in the supply chain

in construction lean construction in it

lean i.t in higher education

lean higher education in public sector

lean government from the text

how to use lean manufacturing methods to

introduce innovation

by professor thomas koch we learned that

applying the lean concept in practice

allows to achieve shorter production

period better quality

and significantly lower cost compared to

the traditional approach

in traditionally organized companies the

material from which the product is made

spends weeks often even months in the

plant while its processing time is

measured in minutes or hours

based on the analysis of over 50 case

studies from various industries

carried out by the lean enterprise

institute poland

the most frequently improved indicators

thanks to the use of lean manufacturing

are increase in efficiency by up to 66

percent

increase in the use of machines measured

by oee by as much as 59

reduction of inventory in the course of

production up to 80

reduction of the production space by up

to 61

shortening the time of transition from

raw material to finished product by up

to 70

exchange of dye is time reduction by up

to 96

in addition many companies also mention

other benefits

such as significant improvement in

quality reduction in the number of

complaints

increase in the number of ideas for

improvement presented by employees

improved communication or reduction of

waste

right now management in accordance with

the lean philosophy

is one of the most effective methods in

the world and gives development

opportunities

to all those who want to become involved

in the role of a creator

and to pursue the perfection
