End-users Productivity in Model-based Spreadsheets: An Empirical Study?

Abstract. Spreadsheets are widely used and studies show that most of the exist-ing ones contain non-trivial errors. To improve end-users productivity, recent re-search proposes the use of a model-driven engineering approach to spreadsheets. In this paper we conduct the first empirical study to assess the effectiveness and efficiency of this approach. A set of spreadsheet end users worked with two differ-ent model-based spreadsheets. We present and analyze here the results achieved.
