A Matrix Diagram is a tool used to display the relationship between different factors. It helps in identifying and analyzing the presence and strength of relationships among two or more sets of items. This tool is valuable in quality management as it can help identify the factors that are most influential in a process, thereby assisting in prioritizing areas for improvement.References:
