This 1973 sketch shows the interaction between humans and digital computers, to be used in the Interpretive Structural Modeling process devised by Warfield.
This excerpt from a larger volume shows Fortran code developed for the Interpretive Structural Modeling process. These pages of code show subroutines for displaying relationships and questions on session monitors.
This Battelle photograph shows Warfield (seated, far left) conducting an Interpretive Structural Modeling session sometime on or before 1974. Note the computer terminals on the tables.
