00:00:00
imagine you've been tasked with a really
00:00:02
important project at work the company
00:00:04
you're working for produces luxury cars
00:00:07
the production numbers are going down
00:00:09
and a lesser number of cars are getting
00:00:11
manufactured each day there also seems
00:00:13
to be an issue with the quality of the
00:00:15
windshield wipers that go on these cars
00:00:17
the question you are faced with is there
00:00:20
a way for the company to stop the stall
00:00:22
in production and increase the
00:00:23
production per day from 1 000 to 2 000
00:00:27
also is there a way to find out what's
00:00:30
causing the drop in the wiper quality
00:00:32
there is
00:00:33
six sigma
00:00:35
six sigma gives you the tools and
00:00:37
techniques to determine what's making
00:00:39
the manufacturing process slow down how
00:00:41
you can eliminate the delays improve the
00:00:43
process and fix further issues along the
00:00:46
way the concept was introduced in 1980
00:00:49
by bill smith while working for motorola
00:00:52
since then six sigma has seen worldwide
00:00:55
adoption
00:00:56
six sigma aims to reduce the time
00:00:59
defects and variability experienced by
00:01:02
processes in an organization thanks to
00:01:04
six sigma you can produce an effect-free
00:01:07
product
00:01:09
99.9996 percent of the time allowing
00:01:12
only 3.4 errors per 1 million
00:01:15
opportunities
00:01:16
six sigma also increases customer
00:01:18
loyalty towards the brand improves
00:01:21
employee morale leading to higher
00:01:23
productivity
00:01:24
six sigma has two major methodologies
00:01:27
dmaic and dmadv
00:01:30
let's look at the first methodology
00:01:33
dmaic is an acronym for define measure
00:01:37
analyze improve and control
00:01:40
let's have a look at each of these
00:01:42
stages individually and how it relates
00:01:44
to your earlier problem
00:01:46
in the define phase you determine what
00:01:49
issues you're facing what your
00:01:50
opportunities for improvement are and
00:01:53
what the customer requires of you
00:01:55
here you look at the process as a whole
00:01:58
and determine the issues with the
00:01:59
manufacturing process
00:02:01
in this case finding out why the cars
00:02:03
had varying windshield wiper quality and
00:02:06
how to optimize the current process to
00:02:08
manufacture more cars
00:02:10
in the measure phase you determine how
00:02:12
the process is performing currently in
00:02:14
its unaltered state you determine the
00:02:17
current number of cars that are
00:02:18
manufactured in a day in the current
00:02:20
scenario 1 000 cars are manufactured in
00:02:24
a day and each of these cars are
00:02:25
outfitted with a pair of windshield
00:02:27
wipers by one of 30 machines used some
00:02:30
of the metrics measured are how many
00:02:32
cars are produced in a day time taken to
00:02:34
assemble a car how many windshield
00:02:36
wipers were attached in a day time that
00:02:39
takes them to do so defects detected
00:02:41
from each machine on assembly completion
00:02:44
and so on
00:02:45
following this in the analyze phase you
00:02:48
determine what caused the defect or
00:02:50
variation
00:02:51
on analyzing previous data you find out
00:02:54
that one of the machines that installed
00:02:56
the windshield wiper was not performing
00:02:58
as well as it was supposed to
00:03:00
production was taking longer since the
00:03:02
car chassis was being moved across the
00:03:04
different locations slower as cranes had
00:03:07
to individually pick and drop the frame
00:03:09
this was because the wheels were
00:03:11
attached to the car only in the last
00:03:14
stage
00:03:15
next in the improve phase you make
00:03:17
changes to the manufacturing process and
00:03:19
ensure the defects are addressed
00:03:22
you replaced the faulty machines that
00:03:24
installed the windshield wiper with
00:03:25
another one you also find a way to save
00:03:28
time by attaching wheels on the frame in
00:03:30
the initial stages of the manufacturing
00:03:32
process unlike how it was done earlier
00:03:35
now the car can be moved across the
00:03:37
assembly area faster and finally in the
00:03:40
control phase you make regular
00:03:42
adjustments to control new processes and
00:03:45
future performance based on the changes
00:03:47
made the company was able to reduce
00:03:49
production time and manufacture about 2
00:03:52
000 cars a day with a higher quality of
00:03:55
output dmaic is one of the most commonly
00:03:58
used methodologies in the world it
00:04:00
focuses on improving the existing
00:04:02
products of the organization
00:04:04
the second methodology is dmadv which is
00:04:08
shored for define measure analyze design
00:04:12
and verify it is used when the company
00:04:15
has to create a new product or service
00:04:17
from scratch it is also called dfss or
00:04:20
design for six sigma
00:04:23
let's take the scenario where the
00:04:24
company decides to build a new model a
00:04:27
sports car
00:04:28
in the define phase you define the
00:04:30
requirements of the customer based on
00:04:32
inputs from customers historical data
00:04:35
industry research you determine what you
00:04:37
need to ensure your car becomes a
00:04:39
success the data collected indicates
00:04:42
customers are drawn to cars which can
00:04:43
achieve more than 150 miles per hour
00:04:47
customers are also more inclined towards
00:04:49
cars which have v6 engines and an
00:04:51
aerodynamic frame
00:04:53
then in the measure phase you use the
00:04:56
customer's requirements to create a
00:04:58
specification
00:04:59
this specification helps define the
00:05:01
product in a measurable method so that
00:05:03
data can be collected and compared with
00:05:05
specific requirements
00:05:07
some of the major specifications that
00:05:09
you focus on are the top speed engine
00:05:12
type and type of frame
00:05:14
in the analyze phase you analyze the
00:05:17
product to determine whether there are
00:05:19
better ways to achieve the desired
00:05:20
results areas of improvement are
00:05:23
determined and tested
00:05:25
based on the analysis of the prototype
00:05:27
created in this phase you find that the
00:05:29
product satisfies just about all of the
00:05:31
customer requirements except the top
00:05:34
speed
00:05:35
so research begins on an aluminum alloy
00:05:38
that could possibly meet the speed
00:05:39
requirements of the customer following
00:05:42
this the design phase based on the
00:05:44
learnings from the analysis phase the
00:05:46
new process or product is designed
00:05:49
revisions are made to the model and the
00:05:51
car is manufactured with the new
00:05:53
material the analysis phase is repeated
00:05:55
based on the new design you also bring a
00:05:58
focus group and see how they receive it
00:06:00
based on their feedback further changes
00:06:03
are made and finally in the verify phase
00:06:06
you check whether the end result meets
00:06:08
or exceeds customer requirements
00:06:11
once you launch your brand new sports
00:06:13
card you collect customer feedback and
00:06:16
incorporate it into future designs
00:06:19
and guess what your customers are loving
00:06:22
the new design and that is dmadv for you
00:06:27
six sigma has also found success in a
00:06:29
number of different industries the
00:06:31
petrochemical healthcare banking
00:06:34
government and software are some of the
00:06:36
industries that have utilized the
00:06:38
concepts of six sigma to achieve their
00:06:41
business goals
00:06:42
another commonly used methodology
00:06:44
adopted by companies around the world is
00:06:47
lean lean is a methodology that aims to
00:06:49
remove any part of the process that does
00:06:51
not bring value to the customer it means
00:06:54
doing more with less while doing it
00:06:57
better the philosophy behind lean comes
00:06:59
from the japanese manufacturing industry
00:07:01
by bob hartman who at the time was part
00:07:04
of toyota
00:07:05
since then across the world services and
00:07:08
manufacturing organizations have
00:07:09
incorporated lean within their
00:07:11
businesses
00:07:12
but what if you could have the best of
00:07:14
both worlds a combination of both six
00:07:17
sigma and length
00:07:19
that's lean six sigma before we get into
00:07:22
lean six sigma we've got a quiz for you
00:07:25
what methodology is used by companies
00:07:28
when they want to release a new product
00:07:30
created from scratch
00:07:32
a
00:07:32
design measure analyze define verify
00:07:37
b
00:07:37

00:07:42
c demand measure analyze improve control
00:07:48
d

now let's get back to lean six sigma
00:08:03
lean six sigma is a methodology that
00:08:05
focuses on eliminating problems removing
00:08:08
inefficiencies in waste while improving
00:08:10
the working conditions to ensure the
00:08:12
customer's needs are better satisfied it
00:08:15
combines the tools methods and
00:08:17
principles of lean and six sigma
00:08:19
we'll have another video detailing the
00:08:21
process of lean six sigma very soon
00:08:24
