Transcripts
in this video you are going to learn
lean manufacturing topics i have
discussed are what is lean manufacturing
5 principles of lean manufacturing 8
waste of lean manufacturing advantages
of lean manufacturing and disadvantages
of lean manufacturing
let's start the video
clean manufacturing is a production
process based on an ideology of
maximizing productivity while
simultaneously minimizing waste within a
manufacturing operation
many manufacturers are using lean
manufacturing principles to eliminate
waste optimize processes cut costs boost
innovation and reduce time to sell in a
fast volatile and ever-changing global
marketplace
to not take full advantage of all of
your resources is to lose efficiencies
and in so doing stunt production
for many people the phrase lean
manufacturing is synonymous with
removing waste and eliminating waste is
certainly a key element of any lean
practice
but the ultimate goal of practicing lean
manufacturing isn't simply to eliminate
waste it's to sustainably deliver value
to the customer
some well-known companies that use lean
include toyota intel john deere and nike
etc
now come to five principles of lean
manufacturing
a widely referenced book lean thinking
banish waste and create wealth in your
corporation which was published in 1996
laid out five principles of lean which
references core principles in many
fields
they are value the value stream flow
pull and perfection
let's discuss each principle separately
one
value
value is identified from the perspective
of the customer and relates to how much
they are willing to pay for products or
services
this value is then created by the
manufacturer or service provider who
should seek to eliminate waste and costs
to meet the optimal price for the
customer while also maximizing profits
[Music]
2. map the value stream
this principle involves analyzing the
materials and other resources required
to produce a product or service with the
aim of identifying waste and
improvements
value streamed mapping comprises the
products entire life cycle from raw
materials through to disposal
anything that does not add value must be
eliminated
i have discussed the product life cycle
in another video check the video in the
description
number three create
flow eliminate functional barriers and
identify ways to improve lead time
this ensures that processes flow
smoothly and can be undertaken with
minimal delay or other waste
lean manufacturing relies on preventing
interruptions in the production process
and enabling a harmonized and integrated
set of processes in which activities
operate in a constant stream
4. establish a pull system
lean manufacturing uses a pull system
instead of a push system
with a push system inventory needs are
determined in advance and the product is
manufactured to meet that forecast
however forecasts are typically
inaccurate which can result in swings
between too much inventory and not
enough inventory this can lead to
additional warehousing costs disrupted
schedules or poor customer satisfaction
lean manufacturing is based on a pull
system in which nothing is bought or you
only start new work when there is a
demand for it
pull relies on flexibility and
communication
5. perfection
lean manufacturing rests on the concept
of continually striving for perfection
via continued process improvements which
is also known as kaizen as created by
toyota motor corporation founder ki
cairo toyoda
it involves targeting the root causes of
quality issues and ferreting out and
eliminating waste across the value
stream
eight waste of lean manufacturing
the lean manufacturing framework that
was originally developed by taiichi ono
for toyota motor company has
applications across every industry today
the original seven wastes identified by
ono have expanded to include one more
related to an organization's employees
you can easily recall the eight wastes
of lean by using the acronym downtime
which stands for
d stands for defects
products services or information are
incomplete or inaccurate
oh
overproduction making something earlier
or faster than needed
making more than what is needed
w waiting
idle time while waiting for materials
equipment parts people or information
n stands for non-utilized talent
not fully utilizing the experience
skills knowledge or creativity of your
team
t
transportation excess
the unnecessary movement of products
equipment or materials
i inventory excess
over accumulation of stock beyond what
is necessary to serve the customer
m motion xs
any movement by the team that is not of
value to the customer
e excess processing
any additional steps in a process that
do not add value to the customer
[Music]
let's move on to advantages of lean
manufacturing
number one
saves time and money
more efficient workflows resource
allocation and production can benefit
businesses regardless of size or output
time saving allows for reduced lead
times and better service in providing
products quickly to customers but can
also help save money by allowing for a
more streamlined workforce
2. environmental friendly
removing unnecessary processes can save
costs in energy and fuel use
this has an obvious environmental
benefit as does the use of more energy
efficient equipment which can also offer
cost savings
three
improved customer satisfaction
improving the delivery of a product or
service at the right cost to a customer
improves customer satisfaction
this is essential to business success as
happy customers are more likely to
return or recommend your product or
service to others
[Music]
disadvantages of lean manufacturing
1. employee safety
by focusing on removing waste and
streamlining procedures it is possible
to overlook the stresses placed on
employees who are given the little
margin for error in the workplace
2. stops future development
lean manufacturing's inherent focus on
cutting waste can lead management to
over focus on the present and disregard
the future
however these may be important to a
company's legacy and future development
