John Krafcik introduced the term “Lean” in his 1988 article, “Triumph of the Lean Manufacturing System,” which detailed Toyota’s production system’s effectiveness. Lean has now been embraced by businesses across a wide range of industries and has become a widely recognised methodology for optimising company processes.
Lean is built on the concept of maximising customer value while minimising waste in the manufacturing process. It tries to reduce non-value-added tasks and streamline processes in order to produce a more efficient and effective system. Lean principles have been used in a wide range of industries, including manufacturing, healthcare, and service.
Toyota Production System (TPS) is a manufacturing method established by Toyota that is intended to reduce waste and increase efficiency. TPS is founded on the principles of just-in-time (JIT) manufacturing, which entails creating only what is required, when it is required. This helps to reduce inventory costs and eliminate overproduction waste.
TPS also promotes kaizen, or continuous improvement, which entails motivating all employees to discover and eliminate waste in the manufacturing process. This is accomplished via the use of methods such as hoshin kanri (policy deployment), genchi genbutsu (seeing for oneself at the source), and the PDCA (plan-do-check-act) cycle.
Another important part of TPS is the use of standardised work, which entails documenting and standardising the most effective method of performing each activity. This reduces variability and ensures constant quality.
TPS has had a significant impact on the development of Lean manufacturing and has been implemented by businesses in a wide range of industries throughout the world.
Another influence on Lean was Henry Ford’s mass production techniques, which transformed the industry in the early twentieth century. Ford’s assembly line strategy centred on optimising the manufacturing process and increasing efficiency.
With the invention of the assembly line, Henry Ford is credited with changing manufacturing in the early twentieth century. Manufacturing was a long and labour-intensive process prior to the introduction of the assembly line, with each product being created by a single craftsman from start to finish.
Ford’s assembly line method divided the manufacturing process into smaller sections and employed specialised machinery to complete each operation. This facilitated the mass production of things at a much faster and lower cost.
The assembly line also introduced the concept of standardisation, as each product was produced using the same set of parts and processes. This contributed to the improvement of product quality and uniformity.
Ford’s mass production tactics influenced the development of Lean manufacturing, which likewise emphasises process simplification and waste reduction to boost efficiency and minimise costs.
Motorola first used the term “Six Sigma” in the 1980s to define the company’s objective of achieving a defect rate of 3.4 parts per million opportunities in its manufacturing processes. This goal was based on the statistical concept of six standard deviations, which represents a high level of quality and a low level of defects.
Six Sigma was used at Motorola as a structured problem-solving approach that employed data and statistical analysis to identify and remove process faults. The methodology contained a DMAIC (define, measure, analyse, improve, control) five-step strategy that assisted organisations in identifying opportunities for improvement, measuring and analysing existing processes, and implementing changes to improve efficiency and reduce defects.
The introduction of Six Sigma at Motorola was a major milestone in the development of the methodology, and it quickly gained popularity and was adopted by other companies around the world. Six Sigma is now universally acknowledged as a powerful approach for increasing quality and decreasing faults in business operations.
Following Motorola’s success with Six Sigma, the concept was immediately copied by other firms around the world. These businesses understood the importance of employing a structured problem-solving strategy based on data and statistical analysis to discover and eradicate flaws in their operations.
Six Sigma was first used by manufacturers, but it has now been used in a variety of other areas, including healthcare, financial services, and government organisations.
As more firms adopted Six Sigma, the methodology expanded and new tools and techniques were developed to support its deployment. Additional problem-solving methodologies, including as Design for Six Sigma (DFSS) and Lean Six Sigma, were incorporated, as well as training programmes and certification processes to assist firms in developing their Six Sigma capabilities.
The adoption of Six Sigma by other businesses following Motorola had a crucial influence in the methodology’s global adoption and evolution.
Since its inception at Motorola in the 1980s, the Six Sigma approach has grown and been adopted in a wide range of sectors and organisations worldwide. The following are some of the significant ways in which the Six Sigma approach has evolved:
Additional problem-solving approaches: In addition to the original DMAIC approach, additional problem-solving ways have been created to assist in Six Sigma deployment. Design for Six Sigma (DFSS) is a systematic way to creating processes and products that are inherently capable of satisfying Six Sigma quality requirements, and Lean Six Sigma combines Six Sigma ideas with Lean principles to improve efficiency and minimise waste.
Expansion into new industries: Six Sigma was initially used mostly in the manufacturing business, but it has now been adopted by a variety of other industries, including healthcare, financial services, and government organisations. The Six Sigma approach has had to be adapted and customised to meet the distinct needs and problems of these various sectors.
Improvement of training and certification processes: As Six Sigma has become more widely adopted, training and certification programmes have been developed to help organisations build their Six Sigma capabilities. These programmes range from basic Six Sigma awareness training to advanced Six Sigma Black Belt certification.
Integration with other quality management techniques: Six Sigma has been integrated with other quality management approaches over time, including Total Quality Management (TQM) and ISO 9001. This has aided in the refinement and improvement of the Six Sigma technique, making it more widely applicable in many organisational contexts.
The evolution of the Six Sigma technique reflects practitioners’ and organisations’ continual attempts to refine and improve the approach as it is deployed in various industries and contexts around the world.
Lean and Six Sigma are distinct approaches that emerged independently of one another. However, it was rapidly realised that the two techniques were complementary, as they both focused on enhancing business process efficiency and effectiveness.
Lean focuses on maximising customer value while eliminating waste in the manufacturing process, whereas Six Sigma tries to eliminate errors and variation in operations. Organizations can achieve even greater operational gains by combining these two approaches.
In the late 1990s, the complementary nature of Lean and Six Sigma was realised, and the name “Lean Six Sigma” was coined to define the integrated approach. Since then, Lean Six Sigma has been widely adopted as a unified approach to process optimization by businesses across a wide range of industries.
The realisation of Lean and Six Sigma’s complementary nature has played a crucial role in the creation and widespread adoption of the Lean Six Sigma approach.
Since its conception as a unified methodology in the late 1990s, Lean Six Sigma has been widely adopted by businesses across a wide range of industries. The methodology’s versatility and flexibility make it well-suited for usage in a variety of situations, and it has been successfully implemented in industries like as manufacturing, healthcare, financial services, and government organisations.
The following are some of the important aspects that have helped to the spread of Lean Six Sigma in various industries:
Recognition of the methodology’s advantages: Lean Six Sigma’s potential to enhance efficiency and improve corporate performance has been widely recognised, contributing to its broad adoption. Companies have used Lean Six Sigma to cut costs, enhance quality, and boost customer happiness.
Training and support resources: As Lean Six Sigma has become more extensively embraced, a variety of training and support resources have become available to assist organisations in implementing the technique. Certification programmes, consultancy services, and software tools are all included.
Adaptation to various industry contexts: The Lean Six Sigma approach has been developed and tailored to meet the specific needs and problems of several sectors. This has made it more generally usable and contributed to its spread across numerous industries.
The widespread adoption of Lean Six Sigma in diverse industries demonstrates universal acceptance of the methodology’s merits and the availability of resources to support its implementation.
General Electric (GE) is a multinational conglomerate with a long history of leveraging Lean Six Sigma to drive change and improve business performance. Jack Welch, who served as GE’s CEO from 1981 to 2001, was a crucial factor in the company’s implementation of Lean Six Sigma.
Welch recognised the potential of Lean Six Sigma to boost efficiency and competitiveness, and he made its implementation a top priority at GE. He built a corporate-level Six Sigma unit and contributed significant resources to support the organization’s implementation of Lean Six Sigma.
GE developed a variety of Six Sigma projects under Welch’s leadership, including the GE Six Sigma Academy and the GE Appliances Six Sigma Institute. These initiatives offered Six Sigma practitioners with training and support, assisting in the development of the company’s Six Sigma capabilities.
GE was able to make major improvements in efficiency, quality, and customer satisfaction as a result of its Lean Six Sigma efforts. Six Sigma initiatives at the corporation were also acknowledged by industry experts, and the company garnered multiple honours, including the Malcolm Baldrige National Quality Award.
In 1998, GE announced $350 million in cost savings due to Six Sigma, which was a significant factor in the spread of Six Sigma; later, that figure grew to more than $1 billion, and by the late 1990s, nearly two-thirds of Fortune 500 companies were beginning to use Six Sigma initiatives with the goal of reducing costs and improving quality.
Overall, the history of Lean Six Sigma at GE shows how powerful the technique can be in driving change and boosting corporate performance.
The origins of Lean Six Sigma can be traced back to the Toyota Production System, Henry Ford’s mass production techniques, and Motorola’s development of Six Sigma.
