Six Sigma Methodology
Six Sigma Methodology is a business management strategy originally developed by Motorola, USA in 1981.[1] As of 2010[update], it enjoys widespread application in many sectors of industry, although its application is not without controversy.
2. SIX SIGMA METHODS IN PROCESS DESIGN
In the process-planning phase the FMEA-method is widely used. The problem that emerged with the application of FMEA-method is the large number of KPIV (Key Process Input Variables), which do not have a significant influence or have no influence on KPOV
(Key Process Output Variables).To have faster and more effective process design and development in the process planning stage it is necessary to apply Six Sigma tools and methods with which the number of KPIV can be reduced to minimum, or to those variables which have major influence on KPOV. For the selected example, applications of process map and cause-and-effect matrix are proposed.
3.1. Process map
A process map is a graphical representation of a process flow that identifies the steps of the process, the input and output variables of a process and the opportunities for improvements.Every process map should be result of teamwork, because it is impossible that just one person could have all the knowledge about the process.
3.2. Cause-and-Effect Matrix
A cause-and-effect matrix relates the key inputs to the key outputs using a process map and a cause-and-effect diagram as the primary sources of the input information. The key outputs are rated according to their importance, while the key inputs are scored in terms of their relationship to key outputs [4]. A factor of importance for each parameter is rank ordered and Application of Six Sigma methodology for process design quality improvemen 613 every listed input parameter is correlated to every output parameter. Finally, a total value for each parameter is obtained by multiplying the rating of importance with value given to
parameters and adding across for each parameter.To be very certain about the level of a parameter’s importance an additional Pareto analysis will be applied. The Pareto diagram clearly displays information about the relative importance of the factors of a certain problem. This information helps to identify the most important factors, which will be analyzed first. The results obtained with the cause-and-effect matrix can be used for other analysis and optimizations such as FMEA, mutli-vari analysis and design of experiments.
So you’ve heard of Six Sigma Methodology training and always wondered what all the fuss was about. Bottom line… it is a business process that allows companies to drastically improve their profitability. How does it manage to achieve this? Well the concept is simple.
Your Company + Better Processes = $$$$
Everyday you go to work and have a process of getting your work done. Everyday, chances are, there are better ways of doing it quicker and more efficiently. Quickness and efficiency equal a better product or service, a happier customer, and higher profits for your company.
Well in theory yes, but in reality it is quite a daunting task. Just imagine all the possible improvements that can be made. From the custodian to the assembly line, millions of processes are waiting to be improved.
Six Sigma is a highly controlled methodology. It demands that you choose only the very best projects that meet your company’s goals. And once they are chosen it demands that the proper resources are dedicated to it. It requires the project be put through an entire process called DMAIC (Define, Measure, Analyze, Improve, & Control).
Is it really worth it?
If given the dedication it deserves, you bet! There is a reason that Six Sigma is a household term nowadays. It’s all about the quality with Six Sigma. Everything that you do opens up the chances for an error to sneak in. The hope of Six Sigma is to lower those chances. Here’s the breakdown:
Defects per million chances/opportunities
* 2 sigma = 308,537
* 3 sigma = 67,000
* 4 sigma = 6,200
* 5 sigma = 233
* 6 sigma = 3.4
What does that translate into?
How does 20% profit margin increase sound? And that’s just for starters. Every time you move up a sigma, it can easily mean a 20% increase for each sigma level.
Sign me up! How long will it take?
Well that depends on just how good your quality currently is. With the proper dedication a company can move from 3 Sigma to 4 Sigma within 1 year. However, a good rule of thumb is “the higher your Sigma level is… the longer it will take you to reach the next sigma level.” But as the old adage goes, “the best things come to those who wait”.

3 Advantages of Six Sigma
Six Sigma is a business management strategy originally developed by Motorola, USA in 1981.[1] As of 2010[update], it enjoys widespread application in many sectors of industry, although its application is not without controversy.Here are 3 advantages of aSix sigma.
1.Enhance the capacity of business management
Six sigma is based on statics and facts. In the past, the comprehence to management and management theory is more on oral and writing.But six sigma make all these become practise.So,six sigma management becomes a perfect management method in our eyes.
As Welch at General Electric Company 2000 annual report noted: “6σ management to create high-quality, has been magically reduced the General Electric Company in the last complex in the waste management process, simplifying the management process, reducing material costs. 6σ management implementation has been introduced and commitment to high quality innovative products and indication of a necessary strategy. “…
2.save the cost of business operations
For enterprise, all the rubbish products should be abandoned or Re-rework or repair or exchange which would cost . According to the statics of USA, an enterprise who administer 3σ management standard ,its cost of quality problems is about 10%~15% of the sales incomes.After adminstering six sigma,Motorola has saved more than 14 billions between 10 years.
3. increase customer value
6σ management allows businesses to understand and meet customer demand.First of all,Enterprise understand and grasp the needs of customers, then reduce the arbitrary and lower error rate trhough 6σ management principles.thereby enhancing customer satisfaction.
GE’s medical equipment department after the import 6σ management created a new technology has brought revolution in medical testing technology. The past, patients need three minutes to do a body check, and now only takes 1 minutes. Hospital equipment, thus increases the utilization rate, reduced inspection costs. In this way, the company emerged, hospitals, patients were satisfied with the results of three.

Human Sigma
Human Sigma is a Gallup of the global 10 million customers and 10 million research staff, based on a set of proposed staff and services to help companies manage the tools and processes.
The so-called Human Sigma is one of the differences between employees and customers by improving the quality of contact, it would be raised to excellent levels, to reduce the employees and customers in key indicators of the differences in management, enhance its level of performance.
To take full advantage of employees and clients contacts, and in the process of creating real value, companies must learn how to measure and manage customer engagement experience and exposure to employees.
Of the global 10 million customers and 10 million employees on the basis of research, Gallup proposed “Human Sigma” (Human Sigma) rules for managing the business people of this complex system provides a new set of The rules and different ways of thinking.
The difference between Human Sigma and Six Sigma
Six sigma is a kind of measure tool and method to improve the quality and reduce the mistakes of enterprise proccess.It aims at make the mistake of products and proccess cut down under the standard level.
Compared with six sigma, human sigma is not aiming at reduce all the mistakes.
What human sigma pay attention is to improve the performance of a organization and help it to a excellence level to reduce the difference between related stuff and customers.The goal is to reduce the amount of stuffs who do not care about their enterprise to make more stuff and customers to be loyal to their products and services.
5 rules of Human Sigma
Rule # 1: E Pluribus Unum. You can’t measure and manage the employee and customer experiences as separate entities. Because you must manage these human systems in tandem, you may need to reorganize.
Rule #2: Feelings Are Facts. Emotions frame the employee-customer encounter.
Rule #3: Think Globally; Measure and Act Locally. You must measure and manage the employee-customer encounter at a local level.
Rule #4: There Is One Number You Need to Know. We can quantify and summarize the effectiveness of the employee-customer encounter in a single performance measure — the HumanSigma metric — that is powerfully related to financial performance.
Rule #5: If You Pray for Potatoes, You Better Grab a Hoe. Improvement in HumanSigma performance requires deliberate and active intervention through attention to a combination of transactional and transformational intervention activities.

5 Characteristics of Six Sigma
Six Sigma is a business management strategy originally developed by Motorola, USA in 1981.[1] As of 2010[update], it enjoys widespread application in many sectors of industry, although its application is not without controversy.
Characteristics of Six Sigma
(1)Management Idea bases on customer
Six Sigma is based on Customers and pay attention to the customer demand.it aims at studying what is the demand of customer?What they care most?For example,we improves a trunk to double enlarge its power .Double ncreases the loading capacity.It could be achieve easily.However,it is not what the customer need most.Becaue you do that,che cost would increase,Fuel consumption will increase,which is not what the customer need.Then what is the demand of customer?We need to investage and analysize.If before a customer buying a motor car,he need to consider 30 factors.What is the most important factors for them among these 30 factors.They would find out which is the most important and what is the best combination through their caculation method .Thus,Six Sigma would manage project according to the customer demand and put the point at which customers care most.
(2).Improve the customer satisfaction and reduce the cost of resources to enhance organizational performance
There are two goals Six Sigma aims at.One is to improve the customer satisfaction.Through impove customers satisfaction to Occupation to the market and Improve the effectiveness of the organization.Two is to decrease the source cost.Through decrease the source cost espacilly COPQ(Cost of Poor Quality) and improve the incomes of organization.Thus,the main reason why Six sigma is so popular among many organizations is to improve the performance of companies.
(3)Pay attention to statics and facts.
Six Sigma is a kind of management method pay attention to statics and make decision according to figure and statics.Additional,it could not only estimate the products quality ,but also make some working quality and proccess quality which isdiffcult to evalute and measure easily evaluting through figure out DPO and DPMO.So,Six Sigma management make management become a measurable and Digital science.
(4)Six Sigma Is a project-driven management method
The implementation of Six Sigma is a project management approach as the basic unit. Through the implementation of a project to achieve. Black Belt project is usually to be in charge, the lead organization successful completion of the project team through the project to achieve a breakthrough product or process improvement.
(5)Quality Improvement for products and proccess
a obviously characteristics of Six Sigma is outstanding.Through improve the product quality and Process Reengineering to improve the economy effctiveness for economy
