许多现代工程设计方法寻求优化设计，以使系统对客户的价值最大化。这些方法依赖于系统效用函数作为系统价值度量的公式。然而，这里表明，在某些情况下，这种措施是不可能存在的。然后指出，这些情况构成了规则而不是例外。最后表明，通过现代方法追求客户定义的设计优化目标可能导致设计师产生高度不适当和不受欢迎的设计。因此，很明显，全面质量管理（TQM）和质量功能部署（QFD）的方法会导致高度错误的结果。
Many modem approaches to engineering design seek to optimize design in order to maximize the value of the system to its customers. These approaches rely on the formulation of a system utility function as a measure of system worth. It is shown here that, under certain circumstances, however, such a measure cannot exist. It is then indicated that these circumstances comprise the rule rather than the exception. Finally it is shown that pursuing the objective of design optimization as defined by the customers via contemporary approaches can lead the designer to highly inappropriate and undesirable designs. As a consequence of this, it becomes apparent that the methods of Total Quality Management (TQM) and Quality Function Deployment (QFD) can lead to highly erroneous results.
