This was a workshop given at Instituto Tecnologico Y de Superiores Escuelas, Monterrey, Mexico, for faculty members at the Institute. The manuscript materials in the folder include a lot of travel itinerary sheets and correspondence, plus a draft outline of the course, with lists of a large number of transparencies and Warfield papers which were taken to the seminar for use and distribution to the attendees. The manuscript notes also include class worksheets written by the participants. There is no complete list of names of participants, but among the manuscript papers I find the names of Roxana Cardenas, Carmen Moreno, Carlos Villanueva, Hector Moreira, Andres, Gabriel Vallin, Mary Carmen Temblador, Carlos Mendoza, Hector Rincon NOTE: This manuscript material was misplaced but later found in other file drawers. For a while it was listed as a 1980 manuscript, but actually all this stuff dates from Warfield's December 1989 trip to Mexico. The material is listed in Warfield Collection Finding aid as: "The Management Of Complexity Through Systems Design: A Seminar Workshop," Presented At Itesm, Mexico December 1989 (Box 24 , Folder 32 )
