This document is a pre-publication version of the published document in Conference Proceedings, however I have been doing some web-based searching and can find no mention of the title in the official conference publication, so not sure it ever got into the final printing. Here in my records, the talk manuscript is followed by a copy of John's typed draft list of transparencies planned for the talk. Paper photocopies of John's four transparencies are stored with the off-print at Fenwick Library. In the proceedings, the published paper has the above title, while the presentation he gave at the conference was titled: Design Science: Need, Basis, Discipline, and Application to Large System Design" His talk was given on June 26, 1989.
