Six Sigma: What? Why? How?

I. INTRODUCTION The Six Sigma Starter Company spent millions of dollars of time and time to reduce manufacturing costs and reduce the number of rejects. The groundbreaking principle of trying to solve these problems was originally developed by Motorola and is known as the concept of Six Sigma. This concept began first in the early 1980's and was not widely known until about 10 years later. At the moment, General Electric CEO Jack Welch and Allied Signal CEO Larry Bosidi provided some degree of reliability to the Six Sigma concept through organizational success (Pheng and Hui 2004).

Six Sigma: Many people say TQM has evolved into Six Sigma. The intention of Six Sigma is a business process without errors. Six Sigma is a data driven approach that focuses on reducing variability to eliminate defects within the process. Like BPR, Six Sigma does not need to question the current way of working. However, Six Sigma uses the "adjustment and maintenance" five-step approach to identify the root cause and does not completely redesign the process like BPR. Lean: Lean is also based on the idea of ​​eliminating waste. Lean organizations can eliminate additional management and bring everyone closer to the process. In addition, lean has analytical instructions, each step is fully evaluated. We keep only the value added step. Lean is similar to BPR, but it can achieve results very quickly. They are very different, but lean does not start from the beginning like BPR.

In recent years, some practitioners have combined Six Sigma 's ideas and lean manufacturing to create a method called Lean Six Sigma. The lean Six Sigma approach observes lean manufacturing, solves process and waste problems, Six Sigma is a complementary area designed to promote 'business and operational excellence' with variability and design Focus on. Companies such as GE, Accenture, Verizon, GENPACT, and IBM focus on transformation using Lean Six Sigma, focusing on growth as well as efficiency. From manufacturing and software development to sales and service offering functions, the foundation of the whole organization's innovation.
