F1. What is Lean Six Sigma?
Summary
TLDRLean Six Sigma is a comprehensive approach to process improvement, combining the waste elimination principles of Lean with the variation reduction techniques of Six Sigma. Originating from Toyota in the 1940s and Motorola in the 1980s, it uses metrics to measure process capability and methodologies like DMAIC and DMADV for existing and new processes, respectively. The goal is to achieve high conformance rates, reduce defects to 3.4 per million opportunities, and ultimately satisfy customers while minimizing losses, leading to significant operational savings.

What is the origin of Lean in Lean Six Sigma?
-Lean originated from the Toyota Production System introduced by Taiichi Ohno in the 1940s. It focuses on waste elimination and is considered the practical side of the Lean Six Sigma approach.
Who introduced Six Sigma, and what does it focus on?
-Six Sigma was introduced by Bill Smith and Dr. Michael J. Harry at Motorola in the 1980s. It focuses on variation reduction and is considered the statistical side of the Lean Six Sigma approach.
What is the ultimate goal of Lean Six Sigma initiatives?
-The ultimate goal of Lean Six Sigma initiatives is to satisfy customers by delivering high-quality products and services while minimizing losses and maximizing process efficiency.
How does Lean Six Sigma combine the practical and statistical aspects of process improvement?
-Lean Six Sigma combines the practical waste elimination approach of Lean with the statistical variation reduction techniques of Six Sigma, creating a powerful methodology for driving operational excellence.
Outlines
📏 Introduction to Lean Six Sigma
This paragraph introduces the concept of Lean Six Sigma, a methodology for process improvement and problem-solving. It explains that Lean Six Sigma is a metric for measuring process capability, with a Six Sigma level process producing only 3.4 defects per million opportunities. The paragraph outlines the two methodologies under Lean Six Sigma: DMAIC (Define, Measure, Analyze, Improve, Control) for existing processes and DMADV (Define, Measure, Analyze, Design, Verify) for new processes. The goal of Lean Six Sigma is to reduce unacceptable products or events to a conformance rate of 99.999967%, ultimately aiming to satisfy customers and minimize losses. The origins of Lean Six Sigma are also discussed, highlighting its combination of the practical waste elimination approach of Lean, introduced by Taiichi Ohno at Toyota in the 1940s, and the statistical variation reduction approach of Six Sigma, introduced by Bill Smith and Dr. Michael J. Harry at Motorola in the 1980s.
🚀 Driving Operational Excellence
The second paragraph emphasizes the power of Lean Six Sigma in driving operational excellence. It suggests that the combination of Lean and Six Sigma methodologies results in a more effective approach to improving processes and products. The paragraph is brief but carries the significant message that Lean Six Sigma is a go-to methodology for companies seeking to cut operational costs and enhance their processes, thereby achieving operational excellence.

hi let's start our discussion by asking
ourselves what do we know about Lean Six
Sigma you may avert this lens X Sigma
term from course from your college
program or from your workplace talking
about things that are related to price
improvement and problem solving in this
course we will teach you and we will try
to enlighten you about what really is
plain Six Sigma let's start with some
fundamentals Lean Six Sigma can be
defined using the 3m s first metric
second methodology and third management
system Lean Six Sigma is a metric it is
used to measure the capability of a
process to conform to certain
requirements it is known that if a
process follows a Six Sigma level it
only produces three point four defects
per million opportunities as compared to
lower Lean Six Sigma levels like three
sigma or four sigma that produces more
defects per million opportunities by
having that we can conclude that the
higher the Sigma level the better the
process is second Lean Six Sigma is a
methodology it follows a proven and
effective step-by-step process depending
on the type of process that you want to
manage improved or Explorer we have two
non methodologies under the Lean Six
Sigma body of knowledge first we have
the dimeric define measure analyze
improve and control demise is use for
existing processes
the second methodology is the d-mat V
define measure analyze design and verify
this methodology is used for new process
product or services in this yellow belt
course we will teach you on how to use
the high-level approach of the demotic
methodology third definition as
management system Lean Six Sigma has
been deployed by many companies because
of its proven track of record on helping
them improve their processes resulting
to significant amount of savings
therefore this is a go-to approach for
companies if they want the cut costs of
their operations further if you look
into the details of the Lean Six Sigma
as provided in the screen it is set to
be it's a specific problem solving
approach and set of specialized tools to
be able to improve your process and
products we know for a fact that Six
Sigma is data-driven with a goal of
reducing the number of unacceptable
products or events as we talk about Lean
Six Sigma we are also discussing about
how to reduce process variation to a
degree of what we discussed earlier our
three point four defects per million
opportunities or equivalent to a
conformance rate of 99.99999 6 7% the
goal of these initiatives is ultimately
to satisfy the customer and minimize the
losses but before we go into the details
first we must know where does Lean Six
Sigma originated given in the screen you
can see that there are two different
body of knowledge lean and Six Sigma
let's go first to dean lean is waste
elimination we will talk about waste on
the succeeding sections of this course
this has been introduced by taiichi ohno
a technical engineer of Toyota way back
1940s it is said
believe that lien is the practical side
of the combined Lean Six Sigma approach
Six Sigma Six Sigma focuses on variation
reduction this has been introduced by
Bill Smith and dr. Michael J Hardy at
Motorola
weeba 1980s it is said and believed that
Six Sigma is the statistical side of
Lean Six Sigma few decades ago
practitioners have thought of combining
the practical and statistical side of
the two different body of knowledge and
give birth to Lean Six Sigma a
methodology that is more powerful in
driving operational excellence
