Phaneendra Karody is an industrial engineer and has been in the manufacturing sector for quite some time. He says that the world around us is constantly evolving. To cope with the changing times, we need something to sustain our market position. Sometimes, even though our processes may be performing well, our efficiency and output may not keep pace with our expectations. Here, Six Sigma comes to the rescue. Six Sigma relates to the concept of process capability. A process that operates under Six Sigma will produce no more than 3.4 defective parts per million. Although Six Sigma originated in the manufacturing sector and has been focusing on the reduction of process variation and design, it can be applied to many industries and services. Six Sigma has three key elements- people, process, and technology. The business need for Six Sigma has to be communicated and reinforced at every opportunity until it becomes a part of the organization. The beauty of Six Sigma lies in the fact that it has adopted a large number of preexisting tools to support statistical analysis. The senior management needs to understand the need for Six Sigma. Only then can an organization reap the benefits of Six Sigma revolution.
