Spreadsheet errors are ubiquitous. But, relative to their occurrence frequency, few spreadsheet errors become public. When an organization's spreadsheet errors are publicized, the revelation is seldom made by choice.
Nonetheless, there are many examples of spreadsheet errors being public. Some errors have been widely reported in the media, due to their substantial impacts.
Real newspaper headlines
For example, the following is a sample of real newspaper headlines relating to the use of spreadsheets:
- Brakes hit on Wellington speed reduction plan after $250m error spotted, Stuff.
