What a spreadsheet does well
Start with the honest positive. Excel is instantly available, needs no deployment or IT approval, can calculate anything, and lets you build any table layout in fifteen minutes. For a one-off trend analysis or preparing data for a meeting, it is hard to beat.
The problem is not that spreadsheets are bad. It is that a tool designed for calculation ends up serving as a workflow system, an evidence register and a deadline calendar at the same time.
