8 P’s of Lean

The 8 P’s of Lean refer to a framework used in lean manufacturing and business processes. They are: Purpose: A clear and concise statement of the objective of the process or activity. This helps to keep the focus on the goal and align all efforts towards achieving it. Process: A well-defined and structured approach to … Continued

OEE Overall Equipment Effectiveness

Overall Equipment Effectiveness (OEE) is a key performance indicator used in manufacturing to measure the efficiency and effectiveness of equipment in production. OEE provides a metric for evaluating how well manufacturing equipment is being used by measuring the percentage of time that it is operating effectively to produce good-quality products. OEE is calculated by multiplying … Continued


Heijunka is a lean manufacturing technique that aims to create a production system that is responsive to customer demand, while at the same time reducing waste and increasing efficiency. The word “heijunka” is a Japanese term that roughly translates to “leveling” or “balancing”. The heijunka system involves creating a production schedule that is based on … Continued

Autonomation Vs Automation

Automation and autonomation are two related but distinct concepts in the field of manufacturing and production. Automation refers to the use of technology and machinery to perform tasks that were previously done by human workers. This can include robotic arms on an assembly line, automated conveyor belts, and computer programs that control machines. The goal … Continued


Andon is a visual management tool used in the Toyota Production System (TPS) and other lean manufacturing systems to indicate the status of a production line or work process. The word “andon” comes from the Japanese word for “lamp,” which was originally used to signal problems in the production line. Andon systems typically consist of … Continued

Theory of Constraints (TOC)

The Theory of Constraints (TOC) is a management philosophy developed by Eliyahu M. Goldratt in the 1980s. It is based on the idea that in any organization or system, there is always at least one constraint that limits its performance. The goal of TOC is to identify and manage these constraints to improve the overall … Continued

Central Limit Theorem – Goodyear Quality

The Central Limit Theorem (CLT) is a fundamental concept in probability theory and statistics. It states that if you take a large enough sample of independent and identically distributed random variables from any distribution with a finite mean and variance, then the sample mean of those variables will approach a normal distribution as the sample … Continued

Quality Pioneers: W. Edwards Deming

W. Edwards Deming emphasized the need for changes in management structure and attitudes. He developed a list of “Fourteen Points.” As stated in his book Out of the Crisis they are: Create constancy of purpose for improvement of product and service. Adopt a new philosophy. Cease dependence on inspection to achieve quality. End the practice … Continued

Six Sigma Control Plans / Dynamic Control Plans

Control plans are an important component of Six Sigma methodology that are used to ensure that a process remains in control and meets customer requirements. A control plan is essentially a document that outlines the steps that need to be taken to maintain process stability and consistency, and it includes details on the key process … Continued
