The goal is to do away with inconsistency, waste, and defects that challenge customer loyalty. The Six Sigma Methodology offers a high level of quality that makes every effort to reach perfection in products or services sold by a company, organization, or business.
It is an approach that is data driven and very disciplined for the purpose of getting rid of defects. This method will describe quantitatively how processes are performing. Simply put, a defect is anything that is outside customer specifications. This widely popular tactic has gone through a period of evolution and is now commonly used by the business world.
This approach began in the early s. At that time the three sigma difference from mean was considered an error that needed to be adjusted to enhance quality of production. Afterwards several measurement standards were recommended and the concept developed. Today the registered trademark is Six Sigma. In other words, when a product is within six sigma specifications, there is fewer than 3. The method advanced as a result of practitioners experimenting to resolve problems encountered during production using the process of statistical analysis.
Think about it, you are in the air, feet above the ground, flying in a Boeing Aircraft and suddenly a nut-bolt in the wing of the plane loosens probably due to manufacturing defect making it difficult for the pilot to steer the flight! This is the only reason why defects are not welcome and organizations try to achieve higher Sigma levels. Spelling indicates the total spelling errors. Time indicates the total time it takes to correct those misspellings. We can clearly observe that as the Sigma Level increase, the defects misspellings decrease, the indebtedness reduce and the time for rework also reduces, thus it reduces the DPMO-Defects per Million Opportunities.
What is Six Sigma? What is Quality? What is the Hidden Factory? You can get certified by going through courses offered by certain schools or companies. Keep in mind, though, that there is no unified standard for the courses. As such, the curriculum for Six Sigma certification varies, which means individual courses can vary depending on the offering entity.
Six Sigma is used by corporations and local governments. Below are two examples of how six sigma improved operational efficiency, saved money, and increased customer satisfaction. Microsoft MSFT is one of the largest software producers in the world. In order to improve the reliability and availability of its networks worldwide, Microsoft implemented Six Sigma methodologies to use a robust data-driven process to help eradicate any defects in their systems and data centers to systematically reduce IT infrastructure failures.
The company first established standards for all of its hardware and software to create a baseline measurement for detecting defects. Microsoft used root-cause analysis, including collecting data from past high-priority incidents, server failures, and recommendations from product group members and customers. Using the historical data, Microsoft established baseline standards from which to measure going forward.
Large amounts of data were collected on a daily and weekly basis from various servers. Data analysis and reporting identified the defects and remediation steps for each defect were then established.
The incidents were prioritized based on how severe the defects impacted the business and the company's underlying services. Using Six Sigma methodologies, the teams executed eradication initiatives of the defects. The mean or average time between server failures improved from 18 days to days. As a result of Six Sigma, Microsoft improved the availability of its servers, boosted customer productivity , and increased customer satisfaction.
The local government began to use the program on a county-wide level in and has trained more than 5, employees on employing the methodology.
The county states the savings are coming from hard budget items, which no longer need funding as well as savings in employee hours. You can get your Six Sigma certification through a company or college. Keep in mind, though, that there is no unifying body that standardizes the curriculum. This means that courses can vary based on where you take your course. Six Sigma refers to a methodology that is driven by data and statistics.
It is used by businesses to eliminate defects and improve any of their processes in order to boost their profits. Six Sigma is a process with a certain outcome. Companies implement Six Sigma to help eliminate defects and improve processes so they can boost their profits. Companies that put lean Six Sigma methods into their plans do so in order to improve performance by eliminating waste and defects while boosting the standardization of work.
The key with lean Six Sigma is to add value for the customer. This is an acronym that stands for define, measure, analyze, improve, and control.
