This dissertation examines the relationship between computer technology and management science and changes in the role of profit planning within the commercial banking system of the U.S.A. The objective of the study is to develop a generalized profit-planning model which employs the existing decision processes to create pro-forma financial statements for a commercial bank. The study concentrated on the 300 largest commercial banks (ranked by deposits as of December 31, 1969) of the Federal Reserve System. These particular banks held the greatest potential for having a Planning Department, the computing capability necessary for problem solving, and a Management Science Department actively employing management science techniques to profit-planning problems. The research for the dissertation included an in-depth study of secondary sources, an interrogation of commercial bank executives and a detailed questionnaire which was submitted to each of the 300 largest banks. Sponsorship for the Financial Planning Questionnaire was obtained from the Southwestern Graduate School of Banking at Southern Methodist University, Dallas, Texas. The sponsorship helped obtain a large sample return (in excess of 50.0 percent) and thereby increased the statistical reliability of the results of the study.
