Six Sigma is a way of providing organizations with tools to improve the efficiency of their business processes. This increase in performance and the reduction in process variability help to reduce profits, employee morale, and improve the quality of products or services.

Six Sigma is a technology or principle for improving the quality of the industry. These principles were first introduced by Motorola in the 1980s. All companies, focusing mainly on quality and development in the industry, use this method or principles of Six Sigma. Quality control is an important duty in all industries because all industries want big profits by using few resources, and this is only possible when there is a certain work procedure. Six sigma were found here; Initially, these principles were not used properly in industries because they required proper implementation and high skill. But as market time and competition change, each company begins to implement these principles to improve their product quality. So now we will discuss the full model of the Six Sigma Principles and see how it works and how it is implemented. The basic goal of Six Sigma Methodology is a scale-based strategy that focuses on process improvement and variance reduction through the implementation of six Sigma improvement schemes. This is possible using two Six Sigma sub-methods: DMAIC and DMADV. Six Sigma DMAIC Process (Define, Measure, Analyze, Improve, Control) Existing processes are an improvement system that falls below the specified level and seeks further improvement. The Six Sigma DMADV process is an enhancement system used to develop new processes or products in Six Sigma quality. This can be utilized if an existing process requires more than enhancement enhancement. Performs six sigma processes, six sigma green belts and six sigma black belts, and is supervised by six sigma master black belts.

In 1986, Motorola, Inc. Six Sigma is a quality control method developed. The Six Sigma Cycle provides for time improvement, while reducing construction defects to at least 3.4 events per million units or events. In other words, the system is a system that can run faster with fewer errors. Mathematically, Six Sigma points to the fact that it takes six levels of deviation from the average to make a mistake. Since only 3.4 per million are distributed randomly (normally), events around the one-hour curve are outside the six-standard-variation (Sigma stands for “standard deviation”).

In recent years, Six Sigma has evolved into a public business management philosophy that focuses on meeting customer needs, improving customer retention and improving business products and services. Six Sigma applies to all industries. Many dealers, including Motorola, offer Six Sigma training with special certifications such as Yellow Belt, Green Belt and Black Belt.

Six Sigma represents a management ideology that focuses on the statistical improvements of a business process. It argues for qualitative measures of success rather than qualitative markers. Therefore, Six Sigma trainers are business people who use statistics, financial analysis and project management to achieve better business performance. Six Sigma was developed to define many concepts in the field of business, sometimes confusing. First, it is a statistical benchmark. Any business process that causes a defect of less than 3.4 out of 1 million opportunities is considered efficient. Anything produced outside of customer satisfaction is a defect. Secondly, it is a training and certification program that teaches the basic principles of Six Sigma. Trainers can achieve six sigma certification belt levels ranging from white belt to black belt. Finally, it is a philosophy that promotes the idea that all business processes can be measured and optimized.

Six Sigma is a way to improve business processes using statistical analysis rather than guesswork. Processes are improved by controlling variance and understanding the complexities within them. This leads to more unpredictable and profitable business processes. Six Sigma is more than just “training”; It is a data-based approach that leads to projects with measurable business results. This proven approach has been implemented in a wide range of industries to save hard and soft money while increasing customer satisfaction. For example, in 1999 GE Capital was able to save $ 2 billion using Six Sigma. Six Sigma.us is at the forefront of six Sigma certification and consulting services. We assist organizations in all aspects of the implementation process, from training six Sigma champions to certifying employees at various belt levels. We will help your company determine the right individuals to benefit from the training and advise on how to select potential projects.

History of Six Sigma

1920–1940 was the period when “excellence through testing” began. This is how the quality control inspection division of the companies maintains the quality of the products.

1940–1960 showed us “Statistical Process Control”, in which statistical techniques were used to minimize variation in products so that quality could be controlled or maintained.

The 1960s and 1980s were a time when companies adopted “overall quality management”. Organizations aimed at overall quality assurance.

The period of six sigma in 1987 and beyond is zero defects.

Therefore, Six Sigma is a statistically based approach, a method of continuous improvement that enables companies to eliminate defects in service or process or, most importantly, in a product.

Methodologies of Six Sigma Model

A. DMAIC

It is a method of six sigma principles, which is used for quality improvement and problem solving in different processes. It consists of 5 things, or we can say that it is short:

Define, measure, analyze, improve, and control.

Six Sigma Model 1

1.Define: This is the first step in the process, in which the whole project is thoroughly discussed, and there is no scale of error in the process as each detail is properly defined. In addition, it focuses on issues that may arise during the process, and solutions to these issues are discussed.

2.Quantity: This is one of the most important steps of the method, because in this process, the entire raw information is collected and synchronized, and then it is measured using statistical methods, thus providing accurate information to the staff and the system.

3.Analyze: This is the next step after data collection; At this stage the whole process and data are analyzed and the root causes of different problems are conceptually formulated. Overall, this is an investigative method that is very important and very essential.

4.Improve: After all these steps, the next step, which is the hardest step, is to improve the plan. This is a very comprehensive step because improvisation is very important when collecting and analyzing information, so if there are any glitches in the whole project or any defect is found during the process, it will be fixed in a timely manner.

5.Control: The final step in this process is the control of the entire process so that the project is completed on time and saves resources and time. In addition, the control process is critical to project result-orientation and staff concentration.

B. DMADV

The next method of six sigma is DMADV, which is very important and means a lot in different processes of industries. This is a summary:

Define, measure, analyze, design, and test.

Six Sigma Model 2

1.Define: In the first stage of this methodology, the goal is defined and the goal is set. The project will run smoothly as the entire strategy has been filmed before. The main focus of this process is to get the project on track.

2.Measurement: Measurement is the main step in this method; Different techniques are used to measure the progress of this work, and mathematics and statistics are used to find the exact values ​​of the process.

3.Analyze: Analyze technique is used to find progress and evaluation of the project. In the same way, each step and goal is properly analyzed to match the predetermined criteria so that the entire project will continue online and end properly.

4.Design: In design style, the end result is defined. Synchronizes the entire project, removes excess data, and mitigates the problem that occurred. The design process is an important step in the whole process of this methodology. Also, the manager focuses on this stage because the overall team output is reflected at this stage.

5.Check: The final step of the whole process is the inspection of the entire project, so the final touch to the project will be given before submitting. Inspection is also required because if there is any problem, it will be removed in a timely manner and this will not affect the performance of the entire project.

Levels of Six Sigma

Six Sigma Levels are professionals who exist in each range in an organization, and each executive has a unique role to play in improving the efficiency of a product or service. The various levels of sig sigma tell us who can play what role and when to handle a project. At each level, there is an inherent difference for a professional in the skills, knowledge and technical terminology for undertaking a project. Six Sigma has various levels of certification, which will be discussed in detail in this article. Employees who have completed the certification of Six Sigma are naturally inherent and indispensable in selecting progress and processes in related organizations. They become a part of key partners and evaluate quality control through constant monitoring of projects, processes and services. Through the introduction and adherence to standard protocols, they work to eliminate inconsistencies, disassembly, and defects in construction activities. These key partners are also responsible for establishing measures that help reduce variance in disability. Some of the leading organizations in the world are establishing the standard methods of Six Sigma along with the corresponding measures of lean construction. Together, they cut waste to make their organizations as effective as possible. Six Sigma is one of the few companies that has successfully established its roots in Xerox, 3M and BAE Systems. To achieve the best results for a business by applying the Six Sigma and Lean manufacturing principles, there are experts trained in application tools and the right techniques to take charge of enterprise-wide changes.

Let us now take a look at different levels of Six Sigma. Each level of certification implies the role that a stakeholder is qualified to enact with respect to implementing projects and enhancing quality work in management practices. This helps in equipping trained personnel to be full of active participants when it comes to upscaling their company’s culture and pushing off downtime.

Let us now begin exploring the different levels in the certification ladder and how each one can prove to add to the skillset of the professional, helping him to move forward in his career.

1. White belt

This is the first level of certification in Six Sigma Certification Training. Six Sigma White Belt Holders are professionals who have not previously undergone formal certification training or any other advanced training. This session will give them an overview of the effective methods they need and the vocabulary to learn for LSS workers across the entire range of the organization. It shows how they contribute to efficiency and the most reliable results. With this basic platform, white belt owners participate in projects that lead to problem solving. It revolves around quality management and waste reduction.

2. Yellow belt

Holding this position means exposing Six Sigma’s ideas that go beyond the basics of looking for a white belt holder. Yellow belt practitioners attend training sessions over two days, increasing their knowledge of how to work on the project and interacting with interdependent team members. They may elevate projects with limited potential and assist managers in the belt at the highest level.

3. Green belt

In order to obtain the Green Belt Six Sigma certification, the required professionals are expected to attend the entire course, which will show how to develop, improve and reduce the methods, services and processes of Six Sigma. They know how to apply problem-solving frameworks, one example being DMAIC. This improvement cycle selects several steps to analyze the problems that exist in a business process. They find important measurements to measure changes, to infer relevant data, and to execute solutions that retain results over a period of time. The Green Belt is invaluable to professionals in the field of project management, medical, healthcare, and financial management. It serves as the basis for (FMEA) failure modes and performance metrics and control chart tools such as effect analysis. Once certification is complete, executives will be ready to take charge of projects that fit LSS conceptual connections with organizational goals. They have the knowledge to apply leadership tools to execute operations, find ways to reduce waste, and infer critical views from data.

4. Black belt

This is an innovative level of training for leaders to improve their skills after completing Green Belt certification. Must have prior LSS knowledge is a prerequisite, so it applies when leaders and participants plan to master their skills and knowledge. It helps to note the fact that many complex projects need to be spearheaded that are extensive, disruptive, and require organizational change. Professionals with Black Belt Certification can be considered as expressing their learning and real accounting experience by conducting a live project for their higher studies. It can also be for a non-profit organization. By creating a project charter, collecting data and providing six sigma tools for a real project context, students develop and grow the possibilities needed to increase their business more efficiently, productively and customer satisfaction. Along with the application of lean efforts, they make high-quality improvements that have the potential to have a major impact on a company’s productivity.

5. Master Black Belt

A professional with comprehensive leadership skills and problem-solving approaches can hold the Master Black Belt at LSS. The title of Master Black Belt Holder is about an expert with a broad strategy across the business and thereby coordinating all cross-functional teams.

6. Champion

A professional is called a champion when he is a manager who is at the forefront of LSS deployment and strategy. Now, based on the number of goals set by professional leaders, champions are the ones who help most of the waste minimization and variance elimination initiatives to eliminate faults as per the needs of the company. Led by their leaders with master black belts, such managers are very helpful in advising high quality professionals involved in LSS implementation and tracking how much progress has been made.

Principles of the Six Sigma

Six Sigma has its foundations in five key principles:

1.Focus on the customer

It is based on the popular belief that the consumer is the king. The primary goal is to provide maximum benefit to the customer. To do this, a business needs to understand what drives its customers and their needs, sales or loyalty. It is necessary to establish the standard set by the consumer or market demand.

2.Measure the value stream and find your problem

Map the steps in a given process to determine waste areas. Collect data to identify specific problem areas to address or translate. Have clearly defined objectives for data collection, including defining the data to be collected, the reason for data collection, expected insights, ensuring the accuracy of measurements, and establishing a standard data collection system. Check whether the data helps to achieve the goals, whether the data should be modified or not and collect additional information. Identify the problem. Ask questions and find out the root cause.

3.Get rid of the junk

Once the problem is identified, make changes to the process to eliminate the deviation, thus eliminating the defects. Remove activities in the process that are not added to the customer value. If the value stream does not reveal where the problem is, tools are used to help find the littorals and problem areas. Streamline activities to achieve quality control and efficiency. Finally, by removing the junk mentioned above, the obstacles in the process will be removed.

4.Keep the ball rolling

Include all participants. Adopt a structured process in which your team contributes and collaborates with their diverse expertise for problem solving. Six sigma processes can have a huge impact on an organization, so the team must be proficient in the principles and methods used. Therefore, special training and knowledge is required to reduce the risk of project or re-design failures and to ensure that the process works well.

5.Ensure a flexible and responsible ecosystem

The essence of Six Sigma is business transformation and change. When an incorrect or inefficient process is removed, it requires a change in the working method and attitude of the employees. A strong culture of flexibility and responsiveness to procedural changes can make project implementation efficient. Relevant people and departments should be able to adapt to changes easily, so it should be designed to facilitate and accept processes quickly and without interruption. Ultimately, a company that keeps an eye on the data can achieve a competitive edge if it periodically checks the bottom line and adjusts its processes where needed.

Six Sigma is a way to pursue continuous improvement in customer satisfaction and profitability. It is a management philosophy that seeks to improve efficiency and effectiveness. In this tutorial, you will learn what Six Sigma is and how to use Six Sigma in an organization.
