For at least one hundred years, the industrial world has been striving for ever-greater production performance and better output quality. Six Sigma is one of the most fundamental approaches outlined in the last 35 years. Initially formulated in manufacturing, the methodology is now used in Fortune 500 companies worldwide in medical care and finance. In this article, let's look at the definition of Six Sigma, its origins, principles and methodologies, and how to become Six Sigma certified.
What is Six Sigma?
Six Sigma is a technique that allows business processes by statistical analysis. It is a highly disciplined and data-driven methodology that ensures defect elimination in any company or organizational phase. Organizational procedures must retain a maximum of 3.4 per million (99.99966%) opportunities to achieve Six Sigma.
Motorola developed Six Sigma in 1986 and is essentially collecting tools and techniques to improve processes. Six Sigma is a top way to increase productivity and efficiency of business processes. Six Sigma offers tools and techniques that reduce variance, eliminate defects, help identify root causes of failure, and enable organizations to deliver better products and services for the customer.
Importance of Six Sigma
Since its adoption as a corporate strategy by Jack Welch at General Electric in 1995, Six Sigma has come a long way. It has also been widely implemented in a wide range of all industrial sectors. Implementation of Six Sigma is necessary because it benefits organizations in different ways.
Six Sigma has grown in recent years into a more general corporate management philosophy centered on customer needs, customer engagement, and improvement and sustainability of business products and services.
Understanding of Six Sigma
Six Sigma, which is a management philosophy, focuses on improving business statistics. It supports qualitative performance metrics against qualitative markers. Six Sigma practitioners are those organizational people who use statistics, financial analysis, and project management to enhance their business processes.
Six Sigma has grown to describe various ideas, mostly in the business sphere and sometimes confusing. First, it's a statistical benchmark. Any strategic business plan that produces under 3.4 defects per 1 million chances is considered to be efficient. Anything created other than customer satisfaction is a defect.
Secondly, it's a training and certification program that teaches Six Sigma's fundamental principles. Interested aspirants can achieve the Six Sigma certification belt levels from white to black belt. Finally, this is a methodology that supports the concept of evaluating and optimizing all business processes.
Six Sigma statistics explain how the process is accomplished quantitatively. A measurement approach aimed at enhancing procedures and minimizing variance through the implementation of six Sigma improvement projects is Six Sigma Methodology's fundamental goal. It is done by two sub-methods of Six Sigma: DMAIC and DMADV.
Methodologies of Six Sigma
The letters in DMAIC stands for define, measure, analyze, improve, control. It is a method of improvement in current processes that fall short of the requirements and look for gradual changes.
DMADV stands for define, measure, analyze, design, verify. The Six Sigma DMADV process is an enhancement method used to create new processes or products at the Six Sigma quality level.
Six Sigma Green Belts and Six Sigma Black Belts are executed by Six SIGMA and supervised by Six SIGMA Master Black Belts.
What are the Six Sigma principles?
You can note a minor variance in the Six Sigma principles, depending on where you look. These are the ideas that guide the methodology in general.
- Constant efforts are essential for the growth of the company to achieve reliable and consistent process outcomes.
- The business processes and manufacturing having characteristics can be defined, measured, analyzed, improved, and controlled.
- Sustainable quality improvement needs the whole company's dedication, and maybe particularly of senior and mid-level management.
- All processes can be precisely described, evaluated, and improved: you can monitor outputs by controlling the inputs.
- It is essential for formative evaluation. Stop what you do and think about what has gone wrong or right.
- Variance elimination saves money and avoids defects
What do you know about Six Sigma certification?
Six Sigma certification represents a verification of a person's command for a well-known professional skills development process. Six Sigma training certifications are awarded in stages using a method similar to a belt classification used in karate training.
Though there is no formal body of training or certification, many training organizations offer Lean Six Sigma certification. Various schools and businesses will deliver their variations. Some educational and consulting organizations are joining together to have a version they support. It can be done on-site, self-paced, classroom, online, or in a combination of all. Certificates are issued after completing a written exam, which can be taken online or on paper.
Besides being a prerequisite for workplaces, a Six Sigma credential is present on a resume and can earn as much pay as an MBA. Six Sigma projects will provide benefits, including improved corporate performance, customer loyalty, cost savings, higher income, and more.
- Certified Six Sigma Black Belt (CSSBB): The Six Sigma Black Belt is a specialist who can explain the philosophies and concepts of Six Sigma, including systems and resources. A Black Belt should show team leadership, recognize team dynamics, and select team members' roles and duties. Following the Six Sigma principles, Black Belt understands all aspects of the DMAIC models thoroughly. They have a fundamental knowledge of lean organizational principles, recognize components and practices that are not value-added, and can use those tools.
- Certified Six Sigma Green Belt (CSSGB): The CSSGB works to help the Six Sigma Black Belt or, under the guidance of it, analyses and addresses quality issues.
- Certified Six Sigma Yellow Belt (CSSYB): The CSSYB targets those who have a short position, an interest, or need to build fundamental knowledge in Six Sigma's world. The yellow belt is for entry-level employees who want to strengthen their world or champions who require an outline of DMAIC and Six Sigma.
Final words
Six Sigma focuses on measurable goals, particularly financial objectives, in the context of a new methodology. You can accomplish the objectives with statistically driven decisions and not with hypotheses.
