Covering the period 1968-1991, this "Chronology of Developments" seems to be an outline for a longer paper. It is organized as a "List of Sets" covering work done to develop Warfield's ideas of complexity and the management of complexity through group process design. It is somewhat biographical in nature. The manuscript includes lists of: People involved, Organizations involved, Activities, Startups, Shutdowns, Time periods, Products, Interns, Perturbations, Sponsors, Major ISM sessions, Major software developments, and titles of 31 books/articles by Warfield which he refers to as "Key publications." Written in 1991, this document is very similar to a shorter manuscript of a month earlier titled "Chronology Related to the use of Generic Design Science and Interactive Management" which is also on the Pentium computer.
