~What Are The Differences of Six Sigma and Lean Thinking?~
~Or Even, What Are They?~

What is the differences between Six Sigma
and Lean Thinking?
But.. to know what is the differences between them..
first, we have to know..
what are they?
hmmmm
You see, Six Sigma was developed with a very specific goal
it is to reduce variation
and defect rates in production processes through statistical analysis
to do this, Six Sigma uses one of two '5 step approaches'
either the DMAIC
or the
DMADV method
both methods have their distinct uses
DMAIC stands for
Define
Measure
Analyze
Improve
and Control
this process involves Identifying the problem you're trying to solve,
Taking stock of your current processes,
Identifying and implementing a solution,
and Maintaining that solution in the future
This is perfectly suited for supply chain performance issues
or when only adjustments to the process are needed
not an entirely new function
That is where the DMADV comes in
Define
Measure
Analyze
Design
and Verify
the first phases of the project are the same
but the Design phase allows for the creation of an entirely new tool to solve the problem
the Verify phase then focuses on ensuring that the new solution does, in fact,
continue to solve the problem
The Lean Method on the other hand
is entirely focused on eliminating waste
providing maximum value to customers with the lowest possible amount of investment
or as the Quality Management book says it..
"Getting More Done With Less"
hmmm
typically there are 8 kinds of waste that needs to be eliminated
these are:
Defects
i.e. products that doesn't meet quality standards
Overproduction
i.e. exceeding demand or producing more than what was ordered
Waiting
i.e. process bottle-necks and downtime
Non-Utilized Talent
i.e. ineffectively using or misallocating human resources
Transportation
e.g. inefficient shipping methods
Inventory
e.g. holding on to a surplus of product or raw material
Motion
i.e. unnecessary moving of product, material, or people
and the last one
Extra Processing
i.e. doing more work than is needed
So, let's get back to the main question
"What are the differences between them?"
well,
the primary difference between Lean and Six Sigma is that
Lean is less focused entirely on manufacturing,
but often shapes every facet of a business
also,
Lean is a perfect fit for companies looking to streamline their processes
and offer as much value to the customer as possible
because
it uses the DMAIC method to be the road map for identifying and solving their problems
and as always,
