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
