companies that have used lean six sigmaLean six sigma companies often experience environmental, social and governance (ESG) benefits such as lower energy use, waste reduction and improved product quality.

Focusing on customer value and using data-driven measures, this methodology directs efforts toward those issues which have the highest impact on business success, leading to simpler processes that are easier to oversee and control.

General Electric

Jack Welch’s Six Sigma initiatives at General Electric produced numerous innovations, such as Design for Six Sigma (DFSS). This method seeks to understand what customers desire while anticipating and eliminating defects and inefficiencies from production processes.

GE’s success in this area helped popularize lean and Six Sigma concepts. Now, certifications in Six Sigma can be obtained from many organizations – with American Society for Quality being one of the main providers for Green Belt and Black Belt certifications.

As more companies adopt Lean Six Sigma, its popularity may be declining. A focus on eliminating organizational imperfections and increasing shareholder value may no longer fit with current economic trends and rising millennial workers’ demand for socially responsible companies; furthermore, an approach which emphasizes efficiency could become outdated as companies look for new ways to innovate quickly and frequently.


Six Sigma is a business methodology that emphasizes standard deviation and error management practices to enhance efficiency and reduce costs, as well as increase quality while shortening time-to-market. Six Sigma can be found across industries like aerospace, automotive, energy, healthcare and IT.

Amazon has implemented Lean Six Sigma principles to reshape their operations, employing black belts to manage projects and train employees as well as Kaizen to foster continuous improvement throughout their company. This approach has allowed them to reduce wasteful operations while safeguarding against rapid expansion.

Amazon uses a stringent hiring process to select only top talent. In addition, their variation-control system helps eliminate defective products and shorten delivery times for their products. Their dedication to customer service has propelled Amazon into one of the premier online retailers worldwide; part of its success can be attributed to quality and innovation initiatives.

GE Aviation

GE Aviation is one of the world’s premier aircraft engine suppliers, producing engines used by most commercial planes as well as jet components and systems. Established in 2014, their Asheville facility became one of the first high-volume production facilities for ceramic matrix composite (CMC) materials – outperforming advanced metallic alloys to make jet engines lighter and more fuel efficient.

Jack Welch, CEO of General Electric (GE) from 1995 to 2005, implemented Six Sigma within his organization and credited it for changing the culture, increasing product reliability and cutting costs at GE.

Six Sigma rapidly gained in popularity alongside Lean and Total Quality Management processes, while other quality-focused practices like Lean were also spread. Six Sigma is an approach to quality improvement that draws heavily upon martial arts terminology: newcomers are known as “green belts,” while experts earn black belt status. Six Sigma was tailor-made to appeal to businesses that prefer pseudoscientific management practices; its growth spawned an industry of training institutes offering Six Sigma training, rather than being seen as an all-encompassing management philosophy.

GE Healthcare

Six Sigma is a business improvement methodology that utilizes data analysis to detect and eliminate defects from processes, improving quality and efficiency while increasing bottom line results. Utilizing cross-functional teams, Six Sigma analyzes all aspects of a process before finding potential solutions.

GE Healthcare has taken an innovative approach by adopting lean six sigma. The process allows employees to focus on what really matters while eliminating wasteful practices, leading to improved productivity, customer service, inventory reduction and office streamlining.

Health care organizations have successfully employed General Electric’s lean manufacturing approach to reduce waste and improve patient outcomes. Ochsner health system successfully reduced medical supplies stored on nursing units to eliminate potential safety issues while freeing up space for capacity expansion, while Virtua healthcare system improved patient phone access and prescription refill turnaround time, leading to greater patient satisfaction and higher patient retention rates.
