These are scanned copies of copies. A set of transparencies which Warfield took with him to San Louis Potosi for his talk at ITESM in April 1990. SEE ALSO a paper to go with these transparencies: "Twelve Laws of Design Science.” Presented at Fourth International Symposium on Industrial Engineering and Systems, ITESM(San Luis Potosi), San Luis Potosi, Mexico, 3-6 April 1990. Warfield's talk was given on 4 April 1990. The Spanish title for this conference was: "Cuarto Simposium Internacional de Ingeniera Industrial y de Sistemas" The organizing committee for the S.L. Potosi conference consisted of Senor Vicente Ruiz R. and Senor Jose Manuel Guerra. Warfield stayed at El Hostal del Quijote, in S.L. Potosi. Elements from this paper were later incorporated by Warfield into a longer, better paper titled "Generic Planning: Research Results and Applications" which was the paper written for the Nov. 1990 Von Stichting conference in Amsterdam, and eventually published under the latter title.
