The Six Sigma methodology is one of the most respected and widely used philosophies in business. Are you the owner of a company operating in a competitive industry where innovation and attention to detail are synonymous with long-term success? In this case, applying DMAIC techniques specific to Six Sigma can be essential to the reputation and effectiveness of your brand. But to use Six Sigma techniques successfully, you must be qualified and be in tune with the latest developments in your industry. Why should you invest in a Six Sigma certification? There are many reasons. However, all relate to your personal or business development.

A Six Sigma certification gives individuals the knowledge to approach any internal business problem from a structured, long-term efficiency perspective. A Six Sigma belt, whether Green, Yellow, or Black, gives individuals the skills to succeed in their business roles and implement innovative methods from scratch to improve enterprises’ productivity. A certification, especially an advanced one, is also a plus in any person’s CV and can be a tool for rounding up your income. Expertise in Six Sigma methodology is sought after by employers, who are prepared to pay large sums for highly qualified individuals.


For organizations, professional certification can lead to a better structuring of internal responsibilities, increase the efficiency of the production line, improve the quality of manufactured products, and reduce costly defects. Employing individuals with a Six Sigma certification can create an environment in which positive competitiveness leads to industrial progress, encourages decision-making based on complex data, and improves the consistency of products. Certifications, whether Six Sigma or not, are crucial in the business world and should be present in any organization, regardless of size.

What Is the Influence of Leadership in Six Sigma? 

Six Sigma is a widely used international methodology, and it is suitable for companies active in the manufacturing industry and businesses operating in the financial, medical, or banking sectors. In short, Six Sigma is an option to consider wherever there is a need for internal process efficiency. However, although it is a methodology based on data-making decisions, as with any business philosophy, the company’s leadership will be crucial in determining the method’s effectiveness. Why are leaders critical in a business environment? Decision-making.

The managers of an organization are the ones who can approve the business or marketing strategies for the next quarter. For this reason, if they promote DMAIC methods, their effectiveness and impact on employees will be more significant. In the Six Sigma methodology, leaders should be Black Belt certified and possess the necessary knowledge to perform alongside the employees a strategic analysis of the internal processes used in the organization.

According to the Six Sigma methodology, leaders are the glue that can keep the structure of a company intact. So, they should have the strength of character to make essential decisions no matter how difficult. But leaders, in the business world, are not born with the knowledge to organize and structure companies effectively. For this reason, a professional Six Sigma certification will be crucial, even more so if you own a high-level enterprise. Obtaining a Black or Master Black Belt in Six Sigma can be essential for your organization to reach a higher level and be comparable with other players in your field. 


What Are the Origins of Six Sigma? 

Six Sigma is not a philosophy that appeared overnight, but rather, it is a method that required different innovations and streams of thought, which, over time, have shaped the techniques we use today. The origins of Six Sigma date back to the 1920s, when pioneering statisticians such as Walter Andrew Shewhart succeeded in developing new approaches for using statistical tools in product quality control. Before 1920 and the inception of SQC, product quality varied widely from brand to brand, with no consistent methodology adopted nationally.

Statistical quality control underwent changes, and by the 1950s, with the adoption of the Total Quality Management philosophy, elements reminiscent of the Six Sigma processes used today began to be observed. TQM emphasizes the use of statistical tools in the workplace. But at the same time, it is focused on the employees’ work environment and expertise as well as on creating an atmosphere in which continuous improvements change how customers interact with the products.

The Six Sigma methodology as we know it today did not emerge until 1986 when Motorola introduced DMAIC concepts into its internal structure. In the 1990s, Six Sigma spread to other companies such as Ford and Toyota. Still, the most considerable success was recorded by General Electric, which in the 2000s helped Six Sigma reach its highest level of popularity in decades. Today, Sigma Six techniques have been adopted for the digital age, being used alongside other concepts such as Lean or Kaizen. Moreover, the future of Six Sigma looks as productive as its past.

Can Six Sigma Work for Start-Ups? 


Six Sigma is a methodology mainly associated with national or cross-national conglomerates already operating at a high level who need a method to streamline their internal processes. But although it is unusual, Six Sigma can work for newly formed companies, provided certain elements are met. The Sigma Six methodology is suitable for start-ups operating in manufacturing industries, banking, or healthcare. The reason is that these industries require a high degree of precision, and innovation must give way to exceptional quality control.

Six Sigma is the right tool for companies that want to streamline their production line, reduce operational costs, and achieve high-quality management within their supply chains. But of course, there are also drawbacks. The Six Sigma methodology is resource-intensive and contributes to maintaining superior quality control, disregarding business flexibility. Start-ups, by definition, are dynamic and prone to change, while the origins of Six Sigma come from international corporations operating on a large scale. Could it still work? Yes, but it will depend on your industry and the changes you are willing to make in your firm.
