One
of CITEC's primary objectives is to help Northern New York's
manufacturers eliminate waste in their operations. By eliminating
waste, your company will become more profitable because your
costs will be lower and you will have additional capacity to
sell more products.
The
first step is to identify all of the wasteful processes, both
obvious and hidden, in your company. This is best accomplished
by a fresh set of eyes; not by company employees who have become
acclimated to their surroundings; but, rather by an outside expert
who knows what to look for. The next step is for that expert
to begin working with your employees to eliminate or significantly
reduce the waste, and keep it out of your operation.
CITEC
has identified eight waste factors that may hinder the
efficiency and profitability of your company. These factors can
be difficult to spot and control. Thus, consistent and persistent
effort is required to keep them out of your operation.
#1
- Inventory Waste
Inventory
is a measure of total manufacturing effectiveness. Too much or
the wrong kind of inventory costs money! But the inventory didn't
get there by itself. It was created by the system. Basically,
inventory is a symptom -- it hides underlying issues within a
company.
Inventory
includes raw material, work-in-process (WIP), obsolete goods,
and finished goods. There are many contributing factors to excess
inventory. When inventory is reduced, these underlying issues
are exposed and should be addressed to ensure long term success.
#2
- Defects
Defects
have been Enemy #1 since the late '70s. The concept of "do
it right the first time" is the goal in any process or task
because defects increase the cost of production. So, when you
decrease the incidence of defects, you will lower your production
costs and increase your profits. An additional benefit of reducing
defects is increased employee morale.
#3
- Processing Waste
Defined
as "any effort that adds no value to the product or service
from the customer's viewpoint." There are many tasks, operations,
and processes that occur on a daily basis in your company. Many
are vital for survival. However, based on the definition above,
how many of these tasks, operations, or processes make a difference
to your customer? While it is very difficult to answer this question,
it is one that can add significantly to the efficiency and profitability
of your company.
#4
- Transportation Waste
This
is a killer waste. There is no value in moving material, raw
components, partially completed product, or finished goods around
the plant. Growth, new equipment, and/or additional capacity
present opportunities for more business but can present an opportunity
to introduce increased transportation or motion waste. Poor facility
layout is a large contributor to transportation waste.
#5
- Overproduction Waste
Overproduction
and inventory wastes are closely related. Overproduction increases
WIP, thus overall inventory is increased. Remember, inventory
is a symptom -- a measure of total manufacturing effectiveness.
Many factors contribute to overproduction. By reducing overproduction,
your company can lower inventory, improve quality, have less
rework and experience improved productivity.
#6
- Motion Waste
Motion
waste is "any movement of people or machine that does not
add value to the product or service." Walking, putting something
on a shelf, then going back to retrieve it later is an example
of motion waste. Processing waste, transportation waste, and
motion waste are interrelated -- looking at one requires looking
at the other two. Motion waste is very subtle and its reduction/elimination
must be approached by a systematic methodology.
#7
- Waiting Waste
No
manager, supervisor, or lead person likes to see an operator
standing around or just sitting there...waiting. There are usually
very valid reasons why the operator is waiting to perform their
task. This is one of the many reasons for increased inventory
-- to reduce the waiting time. However, just like inventory,
waiting is a symptom. The root cause of the problem is being
masked or hidden.
#8
- People Waste
Equipment,
machinery, and processes are vital components to an organization
because they can provide the means to produce product "bigger,
faster, better." However, it is the human factor that makes
it all happen.
"The
waste of not using people's (mental, creative, physical, skill)
abilities" is the definition of People Waste. Your
employees have a wealth of knowledge and ideas that need to be
applied to all of these waste factors. Give them the power/authority
to find and address the root causes of these waste factors in
cooperation with their coworkers. After all... "Two heads
are better than one!"

As
manufacturing activity slows, plant managers shift their attention
to increasing efficiency in their factories through lean manufacturing
methods. Knowing exactly where to begin a lean journey is the
first task facing plant managers and improvement teams. The answer
is simple -- the 5S program. The 5S's are: sort, set
in order, shine, standardize and sustain.
5S
is critical to the implementation of all other improvement efforts.
5S significantly helps in implementing other lean tools such
as quick changeover, total productive maintenance and mistake
proofing, and it helps to sustain improvements.
The
goal and process of sorting is organization --
forcing people to remove all items not needed for production.
But people often don't want to let go of parts, machines or data
that might be needed in the future... "just in case." By "red
tagging" items, workers are able to set aside and evaluate
items and information in terms of its usefulness and the frequency
it is used. Those items and information are then either returned,
stored elsewhere, sold, given away or thrown away.
Red
tagging is best done in one target area at a time and within
one or two days. When red tagging is completed, problems and
annoyances in the workflow are reduced, communication between
workers is improved, product quality is increased and productivity
is enhanced.
"Set
in order" organizes a work area
for the maximum possible efficiency. Organization and orderliness
work best when they are implemented together. "Set
in order" means arranging needed items so they are
easy to use and labeling them so anyone can find
them and put them away. The ideal is economy of time and
motion. When orderliness is implemented, there is no wasted
human energy or excess inventory.
"Shine" --
as the word implies -- means to thoroughly clean everything in
the work area. Planning a cleanliness campaign is a five-step
process including: cleanliness targets, assignments, methods,
tools, and follow-up inspections.
The
goals are to turn the workplace into a clean, bright place where
people enjoy working, review the first two Ss and find the source
of dirt or litter and eliminate it. At all times, everything
must be kept swept and clean. "Shine" should become
so deeply ingrained as a daily work habit that tools are also
kept in top condition and are ready for use at any time.
Once
the first three Ss are in place, "standardize" details
a plan to maintain the continual improvement activities. Standardized
cleanup integrates sort, set in order, and shine into a unified
whole, and "sustain" (the
fifth S) involves workers in planning how to keep it that way.
Having clearly designated tasks completed on a regular basis
is the key.
Empowering
shop floor workers to take control of their daily activities
and their work environment is the unifying principle of 5S. By
taking an active role in designing and maintaining their workplace,
workers take more pride in their work leading to greater satisfaction
and higher productivity.
Companies
can understand details of a complex process, and use 5S to implement
the future state map. 5S is the foundation for successful lean
implementation and can be used to begin, support and sustain
the lean journey.

According
to Joseph Day, president/CEO of Freudenberg NOK and chairman
of the Original Equipment Suppliers Association, thousands of
small- and medium-sized manufacturers serving as suppliers to
the auto industry in the United States need to implement the
principles of lean manufacturing.
His
comments, made at the annual meeting of the Shingo Prize (awarded
to companies that best exemplify implementation of lean manufacturing
principles), indicated that the North American auto industry
would suffer greatly if its suppliers don't start embracing lean
practices.
The
big automotive OEMs and their Tier 1 suppliers are spending millions
of dollars adopting lean, but they are not addressing the millions, "perhaps
billions of dollars in waste caused by the sub-tier supply community," says
Day.
For
the North American automobile industry to prosper "we have
to share lean practices throughout the supply chain," says
Day. "We have to create real-world, practical lean training
programs that small companies can afford and we have to create
some bold new economic models that will provide the proper incentives.
If we don't, we won't even have a prayer of competing."
For
a lean program to be a success, Day told the Shingo Prize conference
held last month in Detroit, a company must be persistent, passionate
and relentless in its execution "of all facets" of
the Toyota Production System.
Freudenberg
NOK, with annual sales of $4 billion, has achieved stunning success
with its own lean program called "GROWTH" -- get rid
of waste through team harmony. The company has reduced its defect
rate from more than 2,000 ppm to less than 50; it has reduced
work-in-process inventory by 80%; increased labor productivity
by 25% per year; and has expanded its revenue per 1,000 square
feet of factory space by 350%.
