Think you can't afford
this business initiative? Recent changes have made it more affordable
and accessible than ever.
By Mikel J. Harry andJ. Douglas Crawford
Although six sigma programs
have delivered billions of dollars of profit to large enterprises, they've
done nothing for small to midsize companies. The original Six Sigma architects
didn't design their delivery systems for businesses of that size.
But the business initiative program continues to grow and change, and
many small companies can now afford to implement the most recent iteration
of Six Sigma, called Generation III. In fact, the very drivers of Six
Sigma Generation III are small to midsize companies that need to improve
their performance and profitability. The program is now more affordable
for them because advances in online training technology and a new, smaller-scale
training option help reduce training expenses.
Six Sigma has gained a following among executives and managers for its
ability to reduce cycle time, eliminate product defects, and increase
customer satisfaction. But what is Six Sigma? Loosely defined, the business
initiative program focuses on minimizing errors in processes and products,
and returning that savings to the balance sheet as increased profitability.
Six Sigma is not a quality measurement program, nor is it an alternative
to ISO 9000, which documents processes and generates reports to help maintain
repeatable processes. Strictly speaking, Six Sigma can be defined as maintaining
3.4 errors per million opportunities for error and returning the savings
to the bottom line.
The average U.S. company operates at Four Sigma, which is equal to 6,210
errors per million opportunities for error. Four Sigma is equivalent to
many U.S. airline baggage-handling operations. Six Sigma is equivalent
to the airline fatality rate. To put that in perspective, a person is
about 1,800 times more likely to get to his destination safely than his
luggage is. A company that moves from Four Sigma to Five Sigma can reduce
its number of errors and defects from 6,210 to 233 per million opportunities
for error.
| Evolution of Six Sigma
from Generation I to Generation III |

Generation I
Focuses on defect.
Emphasizes provider
Used in large-scale industrial organizations
Black Belts

Generation II
Focuses on cost.
Emphasizes customer.
Used in large-scale industrial and commercial businesses.
Green Belts

Generation III
Focuses on value.
Emphasizes both customer and provider.
Used in small, medium and large-scale industrial
and commercial businesses.
White Belts

Over the past 20 years, Six Sigma has moved its focus from reducing costs
to creating value. The first iteration of Six Sigma was concerned mainly
with reducing defects; its second iteration was concerned with reducing
costs. The latest iteration, Six Sigma Generation III, aims to help companies
deliver goods and services of the highest value possible. For business
purposes, value is defined as delivering a product or service to the right
spot, at the right time, in the correct volume, and at the lowest possible
cost.
A key change in Six Sigma Generation III's professional designations
makes the program more affordable for smaller businesses. The operational
roles for these Six Sigma professionalswho carry out programs
for companiesare referred to as X-belts, such as green belt or
black belt. The high cost of training a black belt in an actual classroom
and the relatively long wait for a return on investment makes the black
belt cost-prohibitive for those without the deep pockets of a multinational
company. Even a green belt can be expensive to train in a traditional
classroom situation.
But with the introduction of Six Sigma Generation III, a new belt was
createdthe white beltthat requires far less training and
offers a much quicker return on investment. The white belt professional
has a much narrower focus than the black belt professional; he or she
might look closely at a work cell within an organization rather than at
the organization as a whole, for example. A person with a white belt could
complete up to 12 projects each year with the potential of returning $25,000
from each project to the employer's bottom line.
A group of well-placed white belts can return significant savings to the
profit column of a small business. In a multinational company, a high
percentage of the work force can be trained as white belts. Through the
skills of those with white-belt training, Six Sigma can be extended into
previously inaccessible areas throughout every aspect of the business.
Another way Six Sigma Generation III makes the business initiative program
more affordablein addition to creating the white belt professionalis
through online training, which cuts the cost of training by a factor of
10 or more as compared to traditional classroom instruction.
Although the classroom or the onsite training and materials are expensive,
it's the huge cost of employees' lost production time and
travel that puts Six Sigma out of reach for small to midsize companies.
Small businesses don't have the reserves to take employees out
of production for four to six weeks of training. The Internet and its
attendant technologies have made online training as effective as classroom
training, and online training can be done regardless of the belt one seeks.
Live and Almost in Person
When online training first appeared in the early 1990s, the Internet technologies
then available didn't allow for the depth of training students
received in an actual classroom. Today, technologies allow online students
and teachers to develop and present curriculum that is as effective as
classroom training. This has substantially cut the cost of training and
lets small, midsize, and large companies take advantage of Six Sigma.
In fact, anyone who wants to improve skills and earning potential can
take the online classes.
But that's not to say that all Six Sigma online training is created
equal. Online training that relies on PowerPoint slides with a talking
head reading them is of uncertain value.
The Ira A. Fulton School of Engineering at Arizona State University in
Tempe was an early adopter of Six Sigma Generation III online training.
The school's program features a strict curriculum and takes advantage
of the latest Internet technologies, including over-the-expert's-shoulder
video training. The video style lets students see the concepts, ideas,
graphs, and equations as they're explained, just as if they're
in the classroom. Many of the videos show how to use software to analyze
data.

If students don't understand something, they can see it on instant
replay. A real-time interactive online discussion board allows students
to move from online class to online dialogue. Online sessions are followed
by online research assignments and online exams. Because the courses are
taught through the Internet, the cost is reduced by a factor of 10 or
more, when lost productivity and travel are considered.
Because the curriculum is modular, training can be customized to a company's
needs. Managers tell trainers what they need and Arizona State University
staff builds a training curriculum that addresses those needs within two
days.
To make sure that students understand everything they learned, they have
to carry out an actual Six Sigma application project. This ensures that
students are qualified before they're certified as practicing Six
Sigma black, green, or white belts.
Six Sigma
training programs aren't
all created equal. |
Arizona State students, in order to pass the course, must pass the online
certification tests of the Six Sigma Global Registry. The engine powering
the registry is the PowerMatch patented candidate matching system developed
by IdealHire, a Phoenix, Ariz., human resources software system developer.
The registry is a repository of industrial and commercial Six Sigma practitioners
and helps managers who are searching for employees or consultants trained
or experienced in Six Sigma.
The registry is also useful to those professionals who want to become
a part of Six Sigma or who are Six Sigma practitioners and want to validate
their credentials. In their case, the registry evaluates their standing
in industry and gives them feedback about what, if any, additional training
they need to meet their career goals or their company's objectives.
To become a part of the registry and to determine which level they're
qualified for, professionals declare their training and experience, and
take certification tests. They can also determine what additional training
is required to move to the next belt level to advance their career. The
employers benefit by hiring Six Sigma professionals with declared skills
and validated credentials.
Ultimately, all companies, whether big or small, will need Six Sigma to
improve their profitability. These companies will drive the new, affordable
generation of this business initiative. Six Sigma professionals seeking
to improve their career opportunities have never been in a better place
to do so.
