The implementation process and resource requirements of the University of Connecticut Budget Office's online decision support system are described. Successes and failures of shifting to a fully interactive budget review and development process are also reviewed. Special attention is given to the personnel problems and analytical challenges encountered in the evolution to computerization. Examples are cited of financial models and graphics used to facilitate meeting information requests, perform complex revenue and expenditure analyses, and prepare the budget request. The university's Budgetary Decision Support System (BUDDS) consists of the following key data files: summary expenditure information, personnel information, budgeted position control, budget requests and allotments, and budgetary expenditure accounts. The University of Connecticut's budget development system and the interactive budgetary development model are discussed, along with the marketing of the budget. Attention is also given to the report generator, FOCUS, which enables the budget office to tabulate budgetary information. It is noted that reports generated from three FOCUS files enable administrators to monitor budgetary commitments and assure that allocations are obeyed. FOCUS also contains a facility that simplifies the creation of complicaed financial models. (SW)
