ABSTRACT
The technology requirement deals with the allowable or available internal workings of the system to be designed. For physical synthesis considerations during the concept development Phase 2 of the system life cycle, the technology can be thought of as a catalog describing available component parts and giving data about each component. Sometimes the technology requirement specifies severe restrictions. This is frequently the case on smaller system design projects in which the system must be implemented on the equipment and with the personnel that the customer currently has available. In T3SD, the technology is represented by a set of systems—components, to be sure, but systems in their own right. In a technology closed under copying or isomorphism, there are an unlimited number of copies of any system component available in the technology. A system that satisfies the input/output requirement for a system design problem will be buildable, in the mathematical sense, in the given technology only in very rare cases.
