Introduction:
When you look at the economy we see many trends, the most significant is the
customers wanting high quality products "cheaper, quicker, with better service"
driving companies like Apple, UPS, plus the top three automotive company to re-
look at how they do business today. Just take surf on the Internet Google "Lean
versus Traditional Business Practice" and read hundreds of testimonials, plus white
papers on their lean journey high points and low point. Toyota has turn the
automotive business and manufacturing world towards a continuous improvement
trend not only in the manufacturing environment, plus how they focus on business
trends and forecasting business trends over time
In a recent articles found on one these goggled pages `LEAN Executive Blog
­ current thinking about lean leadership, June 2006, the article name is `Change or
Die" this article explains Fords introspective look into themselves and how they
miss the approaching train "Toyota".
It hard to believe Ford General Motors and Chrysler missed the economic
trends and business leverage Toyota has put on this industry over these past few
years. As quoted from this article " Ford, GM and all traditional manufacturers mange
with n infrastructure that is fundamentally different from the management and infrastructure at
Toyota, Honda and the truly lean companies."
"No matter how these traditional companies care, how hard they work to solve there problems
they cannot continue to manage themselves by the old DuPont ROI model with MRP/ERP
systems, Labor focus performance metrics, functional organizational structures, standard cost and

investment decisions by the same old accounting practices and hope to compete with Lean
organizations."
2. Background
One of the largest Business and Economic trends in the industry today is
based on many companies lean transformation efforts and it's impact on the
economics of these industries. With the removal of waste, small lot sizes and
quicker process time, Traditional methods for accounting and business
measurement need to change in order to sustain these efforts.
Accounting change from traditional accounting practices to "Lean accounting"
has both negative and positive condemnation as with any change from the norm.
Lean accounting;
· Provides information for better lean decision-making. This leads to
better and improved revenue and profitability.
· Reduces time, cost and waste by eliminating wasteful transactions and
systems.
· Identifies the potential financial benefits of Lean improvement
initiative and focus on stratifies required to realize those benefits
· Motivates long-term lean improvements by providing lean focused
information and statistics.
· Address Customer value directly by linking performance
measurements to drivers of value creation and driving changes to
maximize this value.
Traditional accounting systems are not wrong, they are best suited for mass
production and when used in lean environmental are mostly counter productive in

meeting and measuring improvement. Some of the short coming when using
traditional methods are such;
· Motivate people to use non lean methods, such as running large
batches and building inventory
· Traditional systems are wasteful they require huge amounts of
unnecessary work, gathering and analyzing data, producing un helpful
report only a few look adding un-useful task to an already waste
burdened process.
· Standard cost can harm lean companies because the based on premises
grounded in mass production methods. (Taylor's Scientific
Management) Lean violates all of the assumptions of mass production.
Where as mass production is based on achieving economies of scale
though long production runs, lean focuses on making product base on
customer requirements on short production run if possible in one day
It is no wonder that traditional methods lead people to make bad decisions,
such as out sourcing items that should be in sourced. The method are complex and
confusing to generate. They provide misleading information which drives
management to make wrong decision on important factor within their business
from all aspects, such as make buy, profitability of sales orders, rationality on
products or customer.
A example of this found in Practical Lean Accounting Chapter One, Why is
Lean Accounting Important, By Brian Maskell and Bruce Baggaley, Productivity
Press, 2004 is the bases for majority of this paper.

Great work!! Or was it?
Unfortunately in this example due to traditional decision making and traditional
accounting practices the company decide to can the lean cell effort based on
increased in production cost. Even though they improved cash dollars by reducing
inventory and improved customer satisfaction by improving on time delivery and
lead time to market, which improves market shares.

3. General Analysis ­Additional rational about the subject
After research from many article and many books to try and address this
course in a objective manor. The above example is what see in real life with most
of the companies I have had the pleasure to work with along in my current career
path with Cooper Power Systems. What are the measurements that move the
needle so we can measure improvement in our lean effort? Is it dollars, customer
satisfaction, on time delivery? All of these are issues facing companies moving
toward "Lean" plus competing in today's world. What drives our business
decisions and our economic? We need to Learn from Ford and the industries
position lost due to this traditional method of Toyota's Business and Economies.
We need to be sure that once we pull the waste from our transaction based process
we have the metric in place to measure were we are going.
4. Traditional versus Lean Accounting methods

7
 
Since lean accounting is a fairly new and not fully accepted concept with the
industry as of yet. The book "Practical Lean Accounting" A proven system for
measuring and managing the lean enterprise, by Brain Maskell and Bruce Baggaley.
Define this subject the clearest in all of my research. As you journey from
traditional accounting to Lean accounting you have to look at you current state.
There are five major categories:
Financial Accounting

Operational Accounting

Management Accounting

Support for the Lean Transformation
Business Management


To best understand your current state value your first need to survey or analyze
the status your value stream. Baggaley and Maskell develop and analytical method
of survey of your current state. The survey below is an example out of their book
that demonstrates how an organization could analyze the value stream.
Understanding the value stream cost structure capacity, which format a bias for
change in organization to reach its future state. Base on the maturity step to a lean
enterprise. Please see Table below:

were we need to improve to follow and enhance long-term future state vision for
the organization's journey into lean Six Sigma. From this quick summary analysis
you can than start breaking the value stream down by process step, capacity
utilization and all of the transactional process steps supporting their value stream
while understanding their non-productive and productive value.
