Current structured analysis tools are plagued by such problems as long
completion times, complex notation, high costs, and voluminous docume
ntation. To overcome these difficulties, the authors propose three new
tools for effective definition of integrated information systems for
manufacturing systems: the triple diagonal, the user-concept diagram,
and the concept map. The triple diagonal is used to identify and prior
itize major information system modules required of the factory. The us
er-concept diagram plays a complementary, expansive role to the triple
diagonal as it serves to model the details of the process flow for ma
jor information system modules. The concept map is used in parallel wi
th both of the above tools to help structure important entity/object c
lasses making up the database. The tools were tested through a case st
udy involving a startup information system design effort. This effort
involved the verification of contractor software support of essential
information flows within a large re-manufacturing facility for overhau
l of engines and transmissions. Together, the tools aided the startup
effort by decreasing the time necessary to acquire manufacturing infor
mation system requirements, lowering the costs of such an analysis, an
d improving consensus among the various cross-functional teams respons
ible for the analysis, design and startup of the facility.
