Lean has been applied in many industries, including manufacturing, healthcare, construction, and service sectors, to improve quality, reduce lead time, increase productivity, and lower costs. It is often implemented through a structured approach called the PDCA (Plan-Do-Check-Act) cycle, which involves planning the improvement, implementing it, checking the results, and acting to sustain the improvement. The Lean approach is based on several key principles, including continuous improvement, respect for people, just-in-time production, and visual management. ![]() The methodology emphasizes the importance of identifying and eliminating any activity that does not add value to the customer, such as waiting, overproduction, unnecessary movement, over processing, defects, and unused talent. The core principle of Lean is to focus on the flow of work and the value that is added at each step of the process. It was first developed by Toyota in the 1950s and is also known as the Toyota Production System. Lean is a methodology for process improvement that aims to eliminate waste, increase efficiency, and maximize customer value. It has also been used to improve customer satisfaction and loyalty, by delivering products and services that meet or exceed customer expectations. Six Sigma has been widely adopted in many industries, including manufacturing, healthcare, finance, and service sectors, as a way to improve quality and reduce costs. This process involves defining the problem or issue, measuring the current performance, analyzing the data to identify the root causes of the problem, improving the process by implementing solutions, and controlling the new process to ensure that it is sustainable and continuously improving. The methodology is based on a structured approach called DMAIC, which stands for Define, Measure, Analyze, Improve, and Control. ![]() The goal is to achieve a level of quality where the probability of defects occurring is extremely low (less than 3.4 defects per million opportunities). The core principle of Six Sigma is to identify and eliminate the causes of defects (errors or mistakes) in a process, by using statistical methods and tools. It was first developed by Motorola in the 1980s, and later popularized by General Electric. Six Sigma is a quality management methodology used by companies to improve business processes, reduce defects, and increase efficiency. Yet, before talking about differences I would like to make a brief review of Six Sigma and Lean. While both methods aim to improve the quality and productivity of an organization, there are some significant differences between the two. Six Sigma and Lean are two popular methodologies used in business management in order to improve processes, increase efficiency, and reduce waste. ![]()
