π Introduction to Lean Six Sigma and Waste Management
The script introduces the viewer to the challenges faced by a supermarket chain manager, focusing on waste management and supply chain issues, particularly milk delivery delays. It proposes the integration of Lean and Six Sigma methodologies to address these problems. Lean focuses on value provision, waste elimination, and continuous improvement, while Six Sigma is known for process improvement and defect removal. The script delves into the concept of waste, which includes eight categories such as transportation, inventory, motion, waiting, over-production, over-processing, defects, and underutilized skills. It also mentions popular lean methodologies like JIT, 5S, and Kanban, which help optimize processes and reduce waste.
π Improving Supply Chain Efficiency with Six Sigma DMAIC
This paragraph discusses the second issue of improving the supermarket's supply chain efficiency using the Six Sigma DMAIC methodology. The goal is to reduce the milk delivery time to ensure it reaches the shelves before 8:30 AM. The script outlines the steps of the DMAIC process: Define, Measure, Analyze, Improve, and Control. It provides an example of analyzing different delivery routes and identifying the root cause of delays. The improvement phase involves adjusting the milk pickup time and route to save time, while the control phase focuses on monitoring and continuous improvement. The benefits of Lean Six Sigma, such as increased profits, standardized processes, reduced errors, employee development, and value to customers, are highlighted. The script concludes with a quiz question about the type of waste related to motion and an invitation to engage with the SimplyLearn channel.

Transcripts
imagine you're the manager of a
supermarket chain
you've noticed that two things need your
immediate attention
the first issue is how to handle the
different kinds of waste that you
encounter at your supermarket
the next one requires you to address the
supply chain issues at the supermarket
which are causing delays to the morning
delivery of milk
leading to customer dissatisfaction and
attrition
these problems can be solved by
incorporating two of the most popular
quality management methodologies in the
world
lean and six sigma
one famous for its ability to handle
waste and another known for process
improvement
but what if there was a methodology that
combined the concepts of both six sigma
and lean
one that could solve all your issues
well there is
lean six sigma
before we dive into lean six sigma let's
take a closer look at its parent
methodologies
first off lean is a methodology that
focuses on
providing value to the customer
eliminating waste
continuous improvement
reducing cycle time lean and six sigma
both aim to handle waste
but what is this waste
waste is any step or action in the
process that a user does not gain any
value from in short things that users
wouldn't want to pay for
why would a consumer want to pay extra
for the additional truck that was
required to deliver milk to the
supermarket just because the other one
broke down
this waste can be divided into eight
categories let's have a look at each of
them
one transportation this waste refers to
the excess movement of people tools
inventory equipment and other components
of a process than it is required
two inventory this waste occurs due to
having more products and materials than
required
this can cause damage and defects to
products or materials greater time for
completion inefficient allocation of
capital and so on
three motion
this refers to the time and effort
wasted due to unnecessary movement of
people equipment or machinery
this could be sitting through inventory
double data entry and so on
4. waiting
this can be time-wasted waiting on
information instructions materials or
equipment
5. over-production
this is the waste created due to
producing more products than required
six over processing
it refers to more work more components
or more steps in a product or service
than required
seven defects
this is the waste originating from a
product or service that fails to meet
customer expectations
8. skills
this waste refers to the waste of human
potential under utilizing capabilities
and delegating tasks to people with
inadequate training
for years now many systems have emerged
that use the lean methodology to
identify and handle the different kinds
of waste
some of the more popular and effective
ones are
jit or just in time
5s and kanban
the jit methodology focuses on reducing
the amount of time the production system
takes to provide an output
and the response time from suppliers to
customers
5s is another methodology that focuses
on cleanliness in organization while
improving profits and efficiency
kanban is also another popular
methodology to achieve lean
it is a visual method to manage tasks
and workflows
kanban enables users visualize the
workflow to identify issues in the
process and fix them
these methodologies help in optimizing
the waste production
and are often used together to maximize
results
so that's the first problem solved now
let's have a look at how you can improve
the supermarket supply chain efficiency
for that let's have a look at the other
part of lean six sigma
six sigma
six sigma is a set of tools and
techniques that are used for process
improvement and removing defects
let's see how six sigma makes that
possible
six sigma has two major methodologies
dmaic and dmadv
you can learn more about these two
methodologies by checking out our six
sigma in nine minutes video by clicking
on the top right corner
let's have a closer look at dmaic since
lean six sigma uses the dmaic
methodology of six sigma
dmaic is an acronym for define
measure analyze improve control
it is used to improve existing products
and processes so that it can meet the
customer's requirements
in the define phase you determine what
the goals of the project are
in this case you want to reduce the
amount of time taken to deliver milk
from the warehouse to the supermarket so
that it is stocked on the supermarket
shelves before 8 30 in the morning
in the measure phase you measure the
performance of the current unaltered
process
the milk truck leaves at 7 30 a.m in the
morning and can take one of three routes
a b and c
route a is currently the preferred one
as it takes only 60 minutes to reach the
supermarket compared to the routes b and
c which takes 70 and 80 minutes
respectively
in the analyze phase you find out why
the defects exist
since routes b and c were school bus
routes by reducing the starting time by
1 hour at 6 30 instead of 7 30 meant
avoiding the traffic routes b and c now
take 40 to 45 minutes to reach the
supermarket route a still takes the milk
truck one hour to get to the supermarket
even when the truck leaves at 6 30 a.m
in the improved phase performance can be
improved by addressing and eliminating
the root causes
now that you've realized that advancing
the milk pickup by an hour and changing
the route to route b can save time you
change the process accordingly providing
your workers with ample time to stock
the milk into the shelves before the
morning rush
and finally in the control phase you
make regular adjustments to control new
processes and future performance
you continue to monitor the delivery
times and try out alternate routes to
continually improve the process and
ensure even faster delivery
this process change led to reduced man
hours and cost enhanced sales and
customer retention
the lean six sigma methodology offers
many such benefits to businesses let's
take a look at some of them
one increase in profits
two standardized and simplified process
three
reduced errors
four employee development 5 value to
customers
and that is lean six sigma for you
now before we're done we've got a quiz
for you
which type of waste refers to the time
and effort wasted due to the necessary
movement of people equipment or
machinery
a inventory
b
waiting
c overproduction
d
motion
