The practice of requirements capture, modeling, and management is more advanced in some fields, such as software engineering, than is currently evidenced in the field of engineering design. This situation is due in part to the increased number of domains that engineering problems span. Software designers, for example, need not concern themselves with physical working principles, material selection, environmental regulations, safety tests, and so forth. To address this situation, we describe a matrix based hierarchical requirements modeling scheme capturing seven domains of interest to engineering design problems. We illustrate how the application of our modeling scheme can foster engineering innovation through examples drawn from automobile sub-systems.
