![]() Six Sigma follows a structured problem-solving approach known as ‘DMAIC’, which stands for Define, Measure, Analyse, Improve, and Control. The term “Six Sigma” refers to a statistical measure that represents a level of quality where the probability of a defect occurring is extremely low, with approximately 3.4 defects per million opportunities. It is vital for organisations to understand How Does Six Sigma Work, to achieve near-perfection by systematically identifying and eliminating sources of variation and defects. Developed by Motorola in the 1980s, Six Sigma has gained widespread recognition and adoption across industries as a powerful tool for improving processes and solving problems. The concept aims to improve quality, efficiency, and customer satisfaction. Six Sigma is a data-driven methodology and management philosophy that focuses on reducing defects and variation in processes. ![]() G) Defects: Number of times spent by employees in identifying and tackling production errors Here is a brief look at the list of the seven categories:Ī) Overproduction: Occurs in cases where unwanted products are madeī) Waiting: Refers to the duration of lag between each production stageĬ) Transport: Occurs because of inefficient movement of materials or productsĭ) Motion: Poor work standards and inefficient movement of employees during tasksĮ) Over-processing: Excess time spent producing products in an inefficient fashionį) Inventory: Inventory levels crossing their capacity leading to work-overload The lean methodology identifies seven categories of waste which are common across most production systems. Organisations can strive to avoid overproduction and excess inventory, thus reducing costs, minimising waste, and responding immediately to customer demand. Moreover, Lean also promotes the concept of pull, which is a demand-driven system where products or services are produced only when needed. The ultimate goal is to create a seamless flow of work from start to finish, minimising delays and waiting times. Organisations can eliminate barriers and bottlenecks and thus improve cycle times, reduce lead times, and increase overall process efficiency. This identification enables them to pinpoint specific areas for improvement and prioritise their efforts.Īdditionally, Lean emphasises the importance of flow, which refers to the smooth and uninterrupted movement of work through a process. Lean practitioners use value stream mapping, which is a visual representation of the entire value stream, to identify areas of waste, bottlenecks, and inefficiencies. A value stream is the sequence of steps and processes involved in delivering a product or service to the customer. They can focus on identifying the value-added activities and eliminate or minimise non-value-added activities in the process.įurthermore, another important concept in Lean methodology is the value stream. Organisations implementing Lean understand that value is defined by their customers, and all activities must be aligned to deliver that value. ![]() One of the fundamental concepts in Lean is value. Organisations can streamline their operations and eliminate waste, thus achieving significant improvements in productivity, quality, and customer satisfaction. Now the core principle of Lean is to identify and eliminate waste, which refers to any activity or process that is not valuable from the customer’s perspective. Lean principles and techniques have since been adopted by various industries worldwide, revolutionising the ways by which organisations approach Process Improvement. It focuses on maximising customer value while minimising waste, ultimately improving efficiency and reducing costs. It was further popularised by Toyota as the Toyota Production System. Lean, also referred to as ‘Lean Manufacturing’ or ‘Lean Thinking’, is a management philosophy and methodology that originated in the automotive industry. Six Sigma: Which methodology is a better option for you? This blog will help you learn the Difference Between Lean vs Six Sigma, which describes a methodical approach to eliminating waste from organisational systems.ģ) Key Difference Between Lean and Six SigmaĤ) Lean vs. But, there more to understand about their differences. While Lean focuses on minimising waste and enhancing process flow, Six Sigma concentrates on reducing defects and process variation. While these approaches share the common goal of streamlining operations and improving overall performance, they have distinct principles, tools, and applications. Thus, it is vital for them to understand the Difference Between Lean vs Six Sigma, two popular methodologies significantly recognised by companies in the pursuit to progress. Organisations are always striving to improve their business processes, reduce waste, and enhance customer satisfaction.
