Overview: Ansoff's Matrix is a strategic planning tool used by businesses to identify growth opportunities by analyzing their current products and markets, and exploring new product and market combinations. 

Definition: Total Productive Maintenance (TPM) is a comprehensive approach to equipment and maintenance management that aims to achieve optimal equipment effectiveness, minimize downtime, and improve overall productivity. TPM focuses on involving all levels of employees in the maintenance process, from operators to maintenance personnel. 

Definition: The Theory of Constraints (TOC) is a management philosophy and methodology that focuses on identifying and resolving constraints or bottlenecks in a system to improve overall performance. It was introduced by Dr. Eliyahu M. Goldratt in the 1980s and has been widely applied in various industries and business settings. 

Definition: Control charts, also known as process behavior charts, are statistical tools used to monitor and analyze process performance over time. They help in identifying and understanding the variation in a process and detecting any special causes of variation that may indicate a process is out of control.   

Definition: Value Analysis, also known as Value Engineering, is a systematic approach used to identify and eliminate unnecessary costs while maintaining or improving the quality, reliability, and functionality of a product, service, or process. It focuses on finding the most cost-effective ways to achieve the desired performance or function. 

Statistical Methodology: Design of Experiments (DOE) is a statistical methodology used to systematically plan, execute, and analyze experiments or tests to understand the relationship between input factors and output responses. It allows for efficient and effective experimentation to optimize processes, products, or systems. 

Quick Changeover Technique: SMED, which stands for Single Minute Exchange of Die, is a lean manufacturing technique used to reduce changeover or setup time in production processes. It aims to minimize the time taken to change from one product or process to another, allowing for more frequent and efficient changeovers.
