TEDxDelft - Felienne Hermans - What Archimedes has to say about spreadsheets November 29, 2011

Favorite:

Felienne Hermans claims spreadsheets are widely used in industry, sometimes even for business-critical applications, but they can be large and complex, making it difficult for their users to understand how they work, and if they work correctly.

Felienne has worked on a software system that visualizes spreadsheet structure and shows the weak points in the spreadsheets design. Tests performed with professional spreadsheet users have for instance shown that the number of ranges, the nesting depth and the presence of conditional operations in formulas significantly increase the difficulty of understanding a spreadsheet.

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
