“…Unfortunately, most emphasis is placed on how information should be presented in computer applications and not on what information should be presented. The literature described many computer design tools that have been developed to aid design teams, however, the reasoning behind the content of Volume 3 the information they present is not discussed [10][11][12][13]. This lack of a cited theoretical basis and a desire to validate and possibly alter the HOQ representation spearheaded the experimentation undertaken to define the informational needs of design teams for product definition.…”

An experiment was conducted to determine how to best represent the information that is used by designers during the product definition process—the first step in the product realization process A real-time protocol session between a design engineer and a customer was recorded while they developed product requirements for a new bass-drum pedal From this session, a base-line representation was developed Three additional protocol sessions were recorded to test the base-line representation during which three other engineers designed products where the definition information was presented according to the base-line representation Results from this testing yielded a slightly changed representation scheme which is presented in this paper The categories of information within the representation were also arranged based on the priorities of use from the three sessions, and a case example for the new representation is also presented This representation has become the model upon which we are developing a computer environment which serves as a common database for product definition during concurrent development of products

“…The coupling of symbolic and numeric computing is increasingly of interest and reports of work along these lines are beginning to appear i9]. One example that might be of interest is the design of a knowledge-based system for architectural code-checking, the LSC Advisor, to be used within an architectural CADD system [5]. It is also worth noting that some of the strategic choices to be modeled in this work, although made in a static environment, have parallels in decisions that in some circumstances would be made more dynamically.…”
