However, until relatively recently, hardware issues have tended to dominate architectural thinking, and software aspects, when considered at all, were often the first to be compromised under the pressures of development. IEEE 1471 was created to provide a basis for thinking about the architecture of software-intensive systems. IEEE 1471's contributions can be summarised as follows (in this list, items in "italics" are terms defined by and used in the standard): IEEE 1471 provides informative annexes that relate its concepts
