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
sort satin order shine standardize
sustain a tool to create a well
organized and orderly workplace
total productive maintenance tpm
thanks to which every person employed in
the company will be able to freely use
the tools needed for work
smed single minute exchange of die
a set of techniques and tools enabling
the quick changeovers of machines
and production processes it is used
wherever high assortment production
flexibility is desired
or where changeovers take too much time
or are very complicated
poke error proofing a tool that helps
eliminate mistakes
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
