History of Six Sigma

History of Six Sigma

→ In the 1800’s the type of industries reveling of masters and craftsmen.

→ Six Sigma is a very good disciplined and quantitative approach to improve a process or product quality with the help of various sets of tools and techniques.

→ The main goal of Six Sigma's project is to reduce the level of the defect is less than 3.4 per million opportunities with the help of reducing the variability available in raw material, process, or it is available in equipment.

→ Where small companies with one master and other helper craftsmen are available for making products.

→ In this era, there are large varieties are available in products but the volume is very less.

→ So, the compulsion of mass production brought Fred Taylor’s Scientific management system in the 1900s.

→ Fred is a scientific management system dividing the process into a small step repeated step after each step there was inspection and inspection was resulting in quality. 

Evaluation of Six Sigma

→ But Inspection means Cost of Poor Quality large amount of defects forgetting produce which created in 1950’s Quality Assurance system got in initiated this post world war 2 eras that system around quality assurance system started developing.

→ In the late 1970s, Motorola started Problem-Solving for its business processes with the help of statistical analysis.

→ The term “Six Sigma” was invented by Bill Smith who was an engineer at Motorola.

→ Which improved quality and was able to sustain mass production but the new the requirement in industries which were asking for high variety at a very low cost.

→ That required some organization system that started developing in the 1980s. Like ISO, Six Sigma, Lean. 

→ Quality Circles Started taking shape in 1979 creating improvement culture in the organization system.

→ Total Quality management got to launch in 1980 and ISO 9000 Series in 1987.

→ The robot can Benchmarking methodology for comparing similar or dissimilar processes brought a huge improvement in 1988’s.

→ And then deployment of strategies 1990 throw the Balance Score Card came into existence.

→ Six Sigma got to launch in 1995 by Motorola and then Lean got its initiation into 2000. 

Six Sigma Time Line

Milestones of Six Sigma

→ In 1987, Motorola successfully initiated the Six Sigma methods in their critical business process for performance improvement.

→ In 1991, Motorola certified its first Black Belt Six Sigma Expert marking a step to train its staff and overall the organization to become expert in it so that it accelerates a speedy process improvement.

→ In 1991, Allied Signal – a large avionics company, (merged with brand Honeywell in 1999) adopted the Six Sigma methods.

→ In 1995, General Electric’s CEO Jack Welch noticed improvements and achievements in other corporate. So he decided to adopt the Six Sigma methodology in GE. After the implementation of Six Sigma, GE claimed to achieve a remarkable cost saving.

→ After getting good benefits in manufacturing, the Six Sigma methodology was also adopted by other than the manufacturing industries as well.

→ Six Sigma became a vision in many companies.

→ In the first stage, the Six Sigma was a defect reduction tool.

→ In the second stage, in GE, it turned out to be the best tool for cost reduction and cost-saving.

→ Nowadays, Six Sigma is a system of value creation all around the world.

→ By the year 2000, Six Sigma became a part of the culture and established itself as the right of the industry.


Value & Significance of Six Sigma

→ Six Sigma is a comprehensive continual improvement program.

→ Initiated by Motorola & further developed by General Electric which is in the present form.

→ Due to Speed of achievement often called as “TQM on steroids”

→ It develops overall problem-solving capabilities.
