The 29 case studies in this report seek to define the policies and practices followed by firms in programing technological change and manpower adjustments. The purpose of the report is to make these policies and practices more broadly known and to extend the range of effective adjustments provided by individual managements. The inquiries were conducted and reports prepared through the use of a "Guide for Case Analysis" (appended to the introduction) which was developed by the participating countries including Austria, Canada, France, The Federal Republic of Germany, Norway, Sweden, The United Kingdom, and The United States. The cases were selected to represent a wide variety of types of changes, industries, and firms. Representative case studies are (1) "Integrating Two Foundries" (Austria), (2) "Introduction of Electronic Data Processing in a Canadian Insurance Company," (3) "Concentration in a Nationalized Industry" (France), (4) "Data Processing and Manpower Savings in Public Administration" (Federal Republic of Germany), (5) "Rationalisation of the Norwegian Customs Service," (6) "Administrative Reorganisation of the Swedish State Railways," (7) "Modernisation and Shift Work in a Cotton Mill" (United Kingdom), and (8) "Halving the Work Force in a United States Petroleum Refinery."
