Many users felt that the lack of sufficient mainframe software support and lengthy systems development time on the part of the MIS group had been partially compensated by the use of PCs. For example, production scheduling in major work centers in the factory was done with a spreadsheet on PCs. However, the principal use for many PCs was as a “dumb” terminal to the mainframe for database inquiry or sending e-mail. In addition, secretaries and engineers routinely used PC word processing to write memos. Of the 300 users on Fort Wayne’s mainframe, about 210 were accessing it through PCs. The remaining users were CAD users.
