Cost efficiency, for example, involves achieving the best possible returns on resources invested but does not specifically address waste in the same direct manner. Quality improvement focuses on enhancing the quality of output, while process mapping is a technique used to visualize processes and identify inefficiencies. While all these concepts can be
