I. INTRODUCTION
IX Sigma has been characterized as the latest management
fad to repackage old quality management principles,
practices, and tools/techniques [7]. At first glance Six
Sigma looks strikingly similar to prior quality management
approaches. However, leading organizations with a track
record in quality have adopted Six Sigma and claimed that it
has transformed their organization. For example, 3M’s Dental
Division won the Baldrige Award and then later adopted Six
Sigma to improve performance even further [16]. The
financial performance of 3M since Six Sigma adoption has
been very impressive [8]. Other organizations with a quality
track record, such as Ford, Honeywell, and American Express,
have adopted Six Sigma as a way to further enhance business
performance
