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

section below for a chance to be one of

three people to win an amazon voucher

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
