扩展属性被定义为复杂系统的属性，其中系统级别的属性值是组件级别的值的函数。例如重量和成本。将系统需求分配给广泛的属性并将这些需求分配给组件会导致每个属性的重大损失，最终导致成本增长数十％，并导致详细设计阶段的主要进度延迟。另一种方法是以目标函数的形式为广泛的属性提供设计指导，并将目标函数从系统级别向下传递到组件级别。
Extensive attributes are defined as attributes of a complex system where the value of the attribute at the system level is a function of the values at the component level. Examples are weight and cost. Assigning system requirements to extensive attributes and allocating these requirements to components causes a significant loss in each attribute, ultimately resulting in cost growth of tens of percent and major schedule delays in the detailed design phase. The alternative is to provide design guidance in the form of objective functions for extensive attributes, and flow the objective functions down from the system level to the component level.
