Put simply, lean six sigma is a data-driven methodology that aims to eliminate variation in processes by employing statistical methods to detect issues and identify their cause in order to eradicate them. Six sigma is a specific value for this deviation, which implies a rate of 3.4 errors per million opportunities (which is a 99.99966% success rate). In statistics, standard deviation measures the amount of variation or dispersion of a set of values. Sigma refers to the Greek letter σ, which stands for standard deviation.Lean refers to the Lean approach, the agility of a process, the speed at which inputs are transformed into outputs.Let’s break down lean and six sigma into its respective parts to get a better understanding: Lean methodology tools such as SMED, JIT or Standardized Work help increase the flexibility, reliability, productivity and quality of the processes, products and services of companies and organizations in different sectors. The lean manufacturing approach seeks to increase the speed of processes by eliminating inefficiencies and optimizing value creation. Its engine is the powerful DMAIC process: Define, Measure, Analyze, Improve and Control. The objective of six sigma is the detection and elimination of the types of waste also known as the causes responsible for the failures or issues in the processes that affect the critical characteristics of the products or services that are of vital importance for the clients. Lean six sigma is a business improvement strategy that integrates two different approaches: Six Sigma and Lean Manufacturing. Six sigma is a method as well as a fact-based, data-driven philosophy that was developed by Motorola in the 1980s when the company had issues satisfying its customers and needed a solution to optimize its manufacturing processes and waste reduction while giving a competitive advantage. It’s a proven method that provides an organization with the tools needed to continuously improve business processes towards perfection, while increasing performance, profits, employee morale and the quality of products and services. One of the most influential methods that has become very popular during the last 30 years is Six Sigma. New technologies and tools are supporting this transformation journey for small and big companies whose goal it is to implement a culture of continuous improvement and maximize efficiency, while growing in today’s fast-paced and competitive environment.įor this digital transformation to be successful, it must be supported by quality control management techniques. It applies to various industries whatever their business model is from electronics (as Motorola proved it in the late 80s) to the industry sectors such as the automotive field as well as the service industries.ĭigital transformation has become the center of every conversation in business settings due to its many advantages. Six sigma is a method that provides an organization with the tools needed to improve business processes and increase performance through a variety of concepts.
