ABSTRACT

SIX SIGMA

Six Sigma is a measure of quality that strives for near perfection. The Six Sigma process uses

data and rigorous statistical analysis to identify "defects" in a process or product, reducevariability, and achieve as close to zero defects as possible.

Using a universal measurement scale, Six Sigma defines and estimates the opportunities for error

and calculates defects in the same way every time, thus offering a means for measuring

improvement. In fact, Six Sigma takes its name from the Greek letter "sigma," which is used instatistics to indicate standard deviation.

Approaches to business improvement have evolved and grown since the early 1900s and today

the process focused, statistically driven Six Sigma methodology has been widely used by

companies such as GE, Motorola, Honeywell, Bombardier, ABB, Sony, DuPont, American

Express, Ford and many other companies in improving the business performance and optimizingthe bottom-line benefits. Although Six Sigma business management strategy has been exploited

by many world class organizations as mentioned above, there is still less documented evidenceof its implementation in small and medium-sized enterprises (SMEs). This paper reports the key

findings of a Six Sigma pilot survey in manufacturing SMEs. The results of the study are based

primarily on descriptive statistics. The results of the study show that many of the SMEs are notaware of Six Sigma and do not have the resources to implement Six Sigma projects. It was also

found that Lean Sigma was not generally popular among SMEs. Management involvement and

participation, linking Six Sigma to customers and to business strategy are the most critical

factors for the successful deployment of Six Sigma in SMEs.
