βOne of the most noteworthy accomplishments in
keeping the price of Ford products low is the gradual
shortening of the production cycle. The longer an article
is in the process of manufacture and the more it is
moved about, the greater is its ultimate cost.β
Henry Ford, 1863 β 1947
βAll we are doing is looking at the time line, from the
moment the customer gives us an order to the point when
we collect the cash. We are reducing the time line by
reducing the non-value added activities.β

Lean Management β A little Bit of History
Eli Whitney developed the concept of
interchangeable parts around 1799
when he accepted an order from the
U.S. Army for the manufacture of
10,000 muskets at the unbelievably
low price of $13.40 each.
For the next 100 years manufacturers
primarily concerned themselves with
individual technologies.
During this time engineering drawings
developed, modern machine tools
were perfected and large scale pro-
cesses (e.g. the Bessemer process
for making steel) held the center of
attention.
That changed in the late 1890s.

Lean Management β A little Bit of History
In the late 1890s, Frederick W. Taylor
began to look at individual workers and
work methods. The result was time
study and standardized work. He
called his ideas Scientific Manage-
ment. The concept of applying science
to management was sound but Taylor
simply ignored the behavioral
sciences.
Frank Gilbreth added motion study and
invented process charting. Process
Charting focused attention on all work
elements including those non-value
added elements which occur between
the "official" elements.
Lillian Gilbreth brought psychology into
the mix by studying the motivations of
workers and how attitudes affected the
outcome of a process.

Lean Management β A little Bit of History
Starting about 1910, Henry Ford
fashioned the first comprehensive
Manufacturing Strategy. He took all
the elements of a manufacturing
system -- people, machines, tooling,
and products -- and arranged them in
a continuous system for manufac-
turing the Model T automobile.
Ford is considered by many to be the
first practitioner of Just-In-Time (JIT)
and Lean Manufacturing.
Ford's success inspired many others
to copy his methods. But most of
those who copied did not understand
the fundamentals. Ford assembly
lines were often employed for
products and processes that were
unsuitable for them.

Lean Management β A little Bit of History
After WW II, Japan started to study
American production methods with
particular attention to Ford practices
and the Statistical Quality Control
practices of Ishikawa, Edwards
Deming, and Joseph Juran.
At Toyota Motor Company, Taiichi
Ohno and Shigeo Shingo, began to
incorporate Ford production and other
techniques into an approach called
Toyota Production System (TPS) or
Just-In-Time (JIT).
Toyota also βdiscoveredβ that factory
workers had far more to contribute
than just muscle power and developed
the concept of Quality Circles.
All of this took place between about
1949 and 1975.

β Eliminate or Reduce Non-Value-Added Activities
Lean Management β Definition of Value Adding Work
Three Criteria for Adding Value
1. Customer wants you to do it (or will pay for it)
2. The material / information is being processed or transformed into final
products or services
3. It is done right the first time

The 7 Wastes β Summary
In the latest edition of the Lean Manufacturing
classic Lean Thinking, Underutilization of
Employees has been added as an eighth
waste.
Organizations employ their staff for their
nimble fingers and strong muscles but forget
they come to work everyday with a free brain.
It is only by capitalizing on employees'
creativity that organizations can eliminate the
other seven wastes and continuously improve
their performance.
Many changes over recent years have driven organizations to become world
class organizations or Lean Enterprises. The first step in achieving that goal is
to identify and attack the seven wastes. As Toyota and other world-class
organizations have come to realize, Customers will pay for value added work,
but never for waste.

Lean Management β The Five Lean Principles
Define Value - Specify value from the Customer
perspective.
Map Value Stream - Identify the value stream for
each product or service and challenge all of the
non-value adding steps (wastes) currently
necessary to create and deliver this product or
service. Add nothing than value.
Create Flow - Make the product or service creation and delivery process flow
through the remaining value-added steps.
Establish Pull β Introduce pull between all process steps where continuous flow
is possible.
Pursuit Perfection β Manage toward perfection so that the number of steps and
the amount of time and information needed to create and deliver this product or
service.

Quick Changeover β Quick Changeover or SMED
ο Quick Changeover or Single-Minute Exchange of Die (SMED)
provides a rapid and efficient way of setting up or converting a

ο Rapid changeovers are a key to reducing processing lot sizes and

ο The phrase "single-minute" does not mean that all changeovers and
setups should take only one minute, but that they should take less
than 10 minutes (in other words, "single-digit minute").

ο Changeover or setup activities can be classified using the following three
categories.
ο§ Waste β Activities which do not add value to the changeover or setup
ο§ Internal - Activities that can only be performed while the equipment is shut down
ο§ External - Activities that can be performed without shutting down the equipment
ο Key strategies to reduce setup and changeover time are:
ο§ Eliminate the waste activities
ο§ Convert as many internal activities to external activities
ο Internal activities can be improved by:
ο§ Use specially designed cart to organize tools
ο§ Use quick-release fasteners instead of bolts and nuts
ο§ Use stoppers to quickly position the jigs.
ο§ Use overhang mechanisms to handle heavy jigs
ο§ Use locating pins and holes to eliminate the adjustment

Quick Changeover β Sources of Waste
Sources of Waste during a Changeover Process include
ο Searching for, finding, lining up, and transporting changeover
tools.
ο Waiting for materials, especially for missing items.
ο Searching for bolts, nuts and washers.
ο Searching for carts or waiting for an available crane.
ο Searching for dies, fixtures.
ο Finding chutes and searching for their bolts.
ο Searching for gauges.
ο Searching for inspection or measurement tools.
ο Checking technical drawings or manufacturing specifications.

Quick Changeover β A Step-by-Step Process
There are seven basic steps to reducing changeover using the SMED system:
1. OBSERVE the current methodology (A)
2. Separate the INTERNAL and EXTERNAL activities (B).
3. CONVERT (where possible) internal activities into external ones (C) (pre-
heating of tools is a good example of this).
4. STREAMLINE the remaining internal activities, by simplifying them (D). Focus
on fixings β For example, it is only the last turn of a bolt that tightens it - the
rest is just movement (waste).
5. STREAMLINE the external activities, so that they are of a similar scale to the
internal ones (D).
6. DOCUMENT the new procedure, and actions that are yet to be completed.
7. DO IT ALL AGAIN: For each iteration of the above process, a 25-35%
improvement in set-up times should be expected, so it may take several
iterations to cross the ten minute line.
45. 45 April 9, 2016 β v2.0
Quick Changeover β Step 1: Observe Current Process
1. Observe the current Changeover Process
ο I find it often very helpful to start a Quick Changeover reduction
initiative by actually videotaping the major activities currently
performed during the changeover process and to review the video
with the improvement team.
ο The key outputs of this first step are to document each step of the
changeover process, as well as determine the cycle time of each
step and for the entire changeover process. A simple Excel
spreadsheet will normally be sufficient to document the results of this
and the following steps.

οΌ The setup person does not have to be disturbed to
explain the steps while the setup is in process.
οΌ Operators observing their own actions are more candid
and not defensive.
οΌ It is not necessary to record on paper every detail of the
setup. Sections can be reserved for later study.
οΌ Time studies have a bad name, the video procedure is
not a time study!

ο Once the team has a clear understanding of the key activities
involved in a changeover, each step needs to be classified using
one of the following three categories.
ο Waste β Activities which do not add value to the changeover
or setup
ο Internal - Activities that can only be performed while the
equipment is shut down
ο External - Activities that can be performed without shutting
down the equipment
ο The results will be documented in the same spreadsheet created in

3. Convert Internal Activities into External Activities (where
possible)
ο During this step, the team identifies internal changeover activities,
means activities that are currently performed while the equipment
is shut down, that can be converted into external activities, means
they can be performed before or after the equipment shutdown.
This can include, organizing all the tools needed for the
changeover or pre-assembling of tools prior to the equipment
shutdown.

be performed during the equipment shut down, means the internal
activities, and develops solutions to simplify or speed up those
activities.
ο Examples include,
ο it is only the last turn of a bolt that tightens it - the rest is just
movement (waste)
ο usage of quick-release fasteners instead of bolts and nuts
