A single incident of compromise with quality can demolish the years of brand value and most importantly, the customer�s trust. While there are many quality systems across the world today, Six Sigma has gained the enormous momentum and acceptance through the industry.
What is Six Sigma?
Six Sigma is a system of statistical tools and techniques that focuses on eliminating defects and reducing process variations. The six sigma process includes measurement, improvement and validation of activities. Six Sigma relates to the number of defects per million opportunities with the standard deviations found in the process specifications. Therefore, six sigma refers to the plus or minus three sigma from the mean of the data under the curve. The individuals are highly skilled and they are trained under the statistical tools like CTQ tree under the six sigma methodologies. The important elements like CTQ trees are developed and explained in the training which is an essential part of the Six Sigma training. The certification and training is borrowed from the martial arts and belts are also derived from it which includes yellow, green, black and master black belt designations.
Master Black Belt
A master black belt trained professional is classically trained in statistical tools, methodology and management process. A master black belt professional is a direct mentor to the group of black belts and six sigma teams through which problems need to be reviewed. The master black belts are responsible for the strategy and training of the black belt level practitioners.
The black belt is considered as the highest level of training in the six sigma tools and training. As per the rule, black belts contribute to develop the plans for six sigma project implementation. A black belt is responsible for creating the project plan and leading the cross functional projects while directing the team members. Black belts usually train other team members with the proper use of Six Sigma tools and techniques.
Green belts generally report to the black belt and it lead the process improvement time to time. On an average 25-50% of Green belt professional�s time is spent working on the six sigma projects within their functional area. Green belts receive training on DMAIC methodology, statistical tools and data collection with analysis on the collected data.
A Yellow Belt have the basic understanding of the Six Sigma and its methodologies, statistical tools and DMAIC methodology. Yellow belts are members of workforce and they are knowledgeable and experience in the process of question. A Yellow belt professional is a subject matter expert for the process.
Six sigma is more than a quality system, it is a set of tools and certification system or method for process improvement. Some professionals perceive it as a philosophy that includes all the business process and measured matric can be improved.
