Six Sigma and Kaizen Compared
This is the first in a series of articles comparing the two leading methods for making business improvements. The series compares these methods with regard to origins, meaning, scope, purpose, benefits, components, methodology, resource demands, risks, and results.
(PRWEB) February 17, 2005 -- To compare Six Sigma and Kaizen is a simple question that has no simple answer for these reasons. First, each term has more than one meaning. Second, there are two different levels at which to compare Six Sigma and Kaizen. You can compare them at the level of making an improvement to a business process (the simplest level) or at the level of a total approach to implementing Quality within a company. Third, there are many sides to the comparison of these two approaches. I can think of nine different ways to compare them. This means that you need to make the comparison between Six Sigma and Kaizen nine times and then, look across those nine comparisons and make a final judgment. Fourth, there is a difference between what people who promote these approaches say and what actually happens in practice. Which do you use to make your comparison?
I will use the following nine ways to compare the two approaches.
| | - Origin of the terms and their various meanings
- Scope of application each approach claims
- Purpose that each approach accomplishes
- Benefits each produces
- Components of each approach
- Methods each approach uses
- Resources each approach requires to succeed
- Risks of using each approach
- Results each approach produces

As to the issue of what proponents say versus what happens in fact, I will try to share that within each section of the comparison, as best I can.
This is my plan. I will accomplish it over a series of months, tackling one or more of the topics listed above. I may change this outline as I move deeper into the issue. I hope that you will investigate each of these separate issues on your own, and share back what you find. In this article, I will share what I understand about the origin of the terms and their various meanings and the scope each approach claims.
