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

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