In these appendices different aspects of the case study approach to organizational change are covered. A comparison is made between on-site interviews and telephone interviews as methods of data collection. It is concluded that in spite of the great disparity in costs, the use of personal interviews is a necessary method for data collection. Methods used in previous studies of agency innovations confirm this need. Copies of the data collection instruments used in the study, including the guidelines for face-to-face interviewing as well as the instruments for telephone interviews, are provided. Eight studies of innovation developed as a result of fieldwork are presented. For each study the background and nature of the innovation, the current status of routinization, and a review of the possible reasons for routinization status are described. A detailed analysis of responses to telephone interviews for these case studies is provided. Also, four traditional approaches to studying bureaucratic innovation are reviewed. (Author/MC)
