Six Sigma A Global Tool for Product and Service Perfection

Six Sigma is a business philosophy that centers on continuous development (NC State University 2003). It is also a management strategy concept that establishes a paradigm of maximum discipline in order to achieve exceptionally high objectives, gathering data and, finally, evaluating results to nearly zero-degree of error forbearance. This serves as a device to trim down waste, defects, and irregularities in both products and services (World Class Manufacturing 2008).
The basis of Six Sigma is founded on the statistical computer of variability or defects of a process (Six Sigma Consultants Inc 2008). It is tagged as the “six standard deviations from the mean.” That explains the usage of the Greek letter sigma (Σ) which is a statistical symbolism that alludes to the disparity from a standard that was previously set. Said to be virtually defect-free, a Six Sigma process for a particular service or manufacturing environment cannot exceed two (2) defects per billion parts produced (NC State University, World Class Manufacturing 2003).
While nearly all companies operate a lenient line of 6,000 defects per million operations of a process, Six Sigma tolerates no more than 3.4 defects in a million operations of a process (NC State University 2003). In line with this, Six Sigma can only be considered achieved given that defects are kept at bay to a close to perfection production rate equivalent to 99.9997%. Consequently, the failure rate of 3.4 parts per million, though generally used, is already an unimaginable figure. The reason for this is that, is that in reality, the said failure rate is equivalent to a rough estimate of 4.5 sigmas (World Class Manufacturing 2008).
In a nutshell, Six Sigma is a ground-breaking business process striving for the dramatic reduction of organizational inefficiencies that eventually translates into revenue and profitability (Six Sigma Consultants Inc 2008).
It all began in&nbsp.the 1980s when Motorola, Inc. embarked on reducing the number of its own&nbsp.production defects by means of procedures that lead to a reduction of waste, improvement of quality, maximum utilization of production time and costs, and concentration on product design and manufacturing.&nbsp.
