Spreadsheets are heavily used in industry, becausethey are easily written and adjusted, using an intuitive visual interface. They often start out as simple tools; however, over time spreadsheets can become increasingly complex, up to the point where they become complicated and inflexible. In many ways, spreadsheet are similar to software: both concern the storage and manipulation of data and the presentation of results to the user. Because of this similarity, many methods and techniques from software engineering can be applied to spreadsheets. The role of SEMS, the International Workshop on Software Engineering Methods in Spreadsheets is to explore the possibilities of applying successful methods from software engineering to spreadsheets. Some, like testing and visualization, have been tried before and can be built upon. For methods that have not yet been tried on spreadsheets, SEMS will serve as a platform for early feedback. The SEMS program included an industrial keynote, 'spreadsheet stories' (success or failure), short and long research papers,a good mix of industrial and academic researchers, as well as lively discussion and debate.
