implement it to improve the quality management of production processes in an organization
Every business needs to have a mindset of continuous improvement. Six look at ios data user statistics Sigma is a methodology that prioritizes quality management and aims to reduce the number of defects and variability in production processes.
Read on to learn more about this methodology and how it can be useful for improving processes and increasing the quality of your business.
What is Six Sigma?
Six Sigma is a methodology developed based on the concept of “sigma”, which in statistics represents a variation, or standard deviation, within a system. The objective of the methodology is to reduce defects as much as possible, increase the quality of products and services and reduce the variability of production processes .
In other words, the method aims to achieve a maximum level of performance and excellent operational efficiency, reducing defects to 3.4 per million opportunities.
This means identifying errors in the process and working with high performance to significantly reduce them, ensuring greater final quality for the company and the customer.
The Six Sigma concept, which brings together several processes and methods, was developed in the 1980s by Motorola, but only gained popularity and was improved later, in the mid-1990s, by Jack Welch, from General Electric.
It is currently widely used in a variety of industries and businesses, ranging from manufacturing and information technology to finance, healthcare and services, helping to reduce waste, lower operating costs and increase business efficiency.
Main concepts of Six Sigma
The Six Sigma methodology has some fundamental concepts for its understanding and operation. Check out the main ones below:
sigma;
DMAIC;
variability;
CTQ (Critical to Quality);
continuous improvement process.
Sigma
In a statistical distribution, sigma represents a variation, that is, a standard deviation within an analysis . In the Six Sigma methodology applied to business, the aim is to obtain the highest quality in production processes, with the lowest number of defects in the process.
Thus, sigma as a representation of variation acts as a kind of quality classification in which the higher the sigma level (6) within this scale, the lower the variability within the process. Consequently, the lower the probability of errors and defects.
DMAIC
It is an acronym that means Define, Measure, Analyze, Improve and Control . It refers to the steps of one of the most used methods in the implementation of the Six Sigma methodology.
Variability
These are changes or deviations within the process . In the Six Sigma methodology, the aim is to reduce variability as much as possible to achieve excellence and the expected final quality.
CTQ (Critical to Quality)
This concept is fundamental within the Six Sigma methodology, as it seeks to identify the crucial characteristics within a process or product to meet customer needs.
When these attributes are not achieved, the quality of the final product is impacted, which is reflected in the customer experience.
When implementing Six Sigma, CTQs are generally defined in the Define and Measure phases of the DMAIC cycle, transforming these characteristics into requirements and helping throughout the improvement process.
Continuous improvement process
This is one of the philosophies of Six Sigma, which aims at the continuous improvement of operations , with the objective of always achieving the highest level of quality within a production process.
This approach is systematic and incremental, seeking to begin and end improvement cycles to achieve and maintain excellence within the organization.
Benefits of Six Sigma
The Six Sigma methodology promotes numerous benefits to businesses, optimizing everything from specific processes to more complex implementations throughout the organization.
Some benefits of Six Sigma are:
promoting a culture of continuous improvement : with a view to constantly improving the organization's production processes;
increase in the final quality of production processes : when applying the methodology, it is expected to observe a significant increase in the quality of products and processes;
increased customer satisfaction : by understanding and improving processes, the likelihood of errors and defects is reduced, increasing end-user satisfaction;
reducing waste and process costs : identifying bottlenecks that lead to inefficiencies is essential to reducing costs and waste;
optimizing operational efficiency and reducing variability : leads to better results and higher quality.
How to implement and what are the steps of Six Sigma?
Six Sigma can be implemented primarily through the DMAIC method, which assumes a cyclical structure. This means that it is a continuous improvement methodology, in which the results generated should serve as a basis for the next improvement cycles.
The DMAIC method is divided into five stages. Using these stages, a company can identify processes, defects and errors, their root causes, and implement improvements in operational processes to achieve excellence in final quality.
