<strong>Total</strong> <strong>Quality</strong> <strong>Management</strong><br />
a company will be selected to receive the Deming award, the quality control circle, and<br />
cause-and-effect diagrams--a principle tool for quality management.<br />
Taguchi’s contributions were centered on explaining the economic value <strong>of</strong> reducing<br />
variation. He maintained that the manufacturing-based definition <strong>of</strong> quality as<br />
conformance to specification limits is inherently flawed. He also contributed to<br />
improving engineering approaches to product design. By designing a product that is<br />
insensitive to variation in manufacture, specification limits become meaningless.<br />
Taguchi advocated certain techniques <strong>of</strong> experimental design to identify the most<br />
important design variables in order to minimize the effects <strong>of</strong> uncontrollable factors on<br />
product variation. Thus, his approaches attacked quality problems early in the design<br />
stage rather than react to problems that might arise later in production.<br />
Taguchi measured quality as the variation from the target value <strong>of</strong> a design<br />
specification, and then translated that variation into an economic "loss function" that<br />
expresses the cost <strong>of</strong> variation in monetary terms. In doing this, Taguchi <strong>of</strong>fered a<br />
method <strong>of</strong> measuring the monetary loss resulting from creation <strong>of</strong> products or services<br />
that do not conform to quality standards. This method was used by Deming to compare<br />
the decreased costs <strong>of</strong> producing products or services with quality values closer to those<br />
<strong>of</strong> standard quality specifications.<br />
