The Future of Spreadsheets in the Big Data Era

The humble spreadsheet is the most widely used data storage, manipulation and modelling tool. Its ubiquity over the past 30 years has seen its successful application in every area of life. Surprisingly the spreadsheet has remained fundamentally unchanged over the past three decades. As spreadsheet technology enters its 4 th decade a number of drivers of change are beginning to impact upon the spreadsheet. The rise of Big Data, increased end-user computing and mobile computing will undoubtedly increasingly shape the evolution and use of spreadsheet technology. To explore the future of spreadsheet technology a workshop was convened with the aim of “bringing together academia and industry to examine the future direction of spreadsheet technology and the consequences for users”. This paper records the views of the participants on the reasons for the success of the spreadsheet, the trends driving change and the likely directions of change for the spreadsheet. We then set out key directions for further research in the evolution and use of spreadsheets. Finally we look at the implications of these trends for the end users who after all are the reason for the remarkable success of the spreadsheet. Alternative Spreadsheet Model Designs for an Operations Management Model Embedded in a Periodic Business Process Thomas A. Grossman, Vijay Mehrotra, Mouwafac Sidaoui, University of San Francisco ABSTRACT We present a widely-used operations management model used in supply and distribution planning, that is typically embedded in a periodic business process that necessitates model modification and reuse. We consider three alternative spreadsheet implementations, a data-driven design, a canonical (textbook) design, and a novel (table-driven) technical design. We evaluate each regarding suitability for accuracy, modification, analysis, and transfer. We consider the degree of training and technical sophistication required to utilize each design. The data-driven design provides insight into poor spreadsheet practices by naïve modelers. The technical design can be modified for new data and new structural elements without manual writing or editing of cell formulas, thus speeding modification and reducing risk of error. The technical design has potential for use with other classes of models. We identify opportunities for future research.We present a widely-used operations management model used in supply and distribution planning, that is typically embedded in a periodic business process that necessitates model modification and reuse.
