The San Diego Unified School District (California) began operating a computerized routing and scheduling system for its pupil transportation services at the beginning of the 1985-86 academic school year. The computerized system, provided by Ecotran Systems, Inc. (ECO) of Cleveland, Ohio experienced an inordinate number of difficulties. A five-member Superintendent's Organizational Study Team was appointed to study the implementation of ECO. The purposes of the study were: (1) to examine the specific problem in transportation resulting in recommendations for improvement effective prior to the beginning of the 1986-87 school year; and (2) to propose a structural process for developing and implementing major interdivisional change efforts within the district. The methodology for conducting this study evolved over time and consisted of several phases, including the definition of the task, study team work sessions, review of organizational diagnosis literature, review of pertinent background documentation, identification of areas for examination, and determining methods of investigation. The findings were in nine theme areas: rationale for automation; planning and implementation; role of the project team and its effectiveness; technology; contract development and administration; ECO organization and performance; structure for communication; dynamics of leadership; and delivery of service: the site perspective. Appendixes include interview protocols, the Ecosystem survey report, flowcharts on ECO implementation, cost data, and a bus route and ridership audit. (JAZ)
