5 reasons your spreadsheets fail

As an Excel programmer I get called in to a lot of scenarios where spreadsheets have failed, crashed or have just become too unreliable to use.

In a recent study by the University of Hawaii, it was discovered that over 80% of the world's spreadsheets contain errors. 70% of those errors affected results that were used in making business decisions.

After speaking to several other Excel programmers, I have compiled a list of the top reasons why spreadsheets fail to live up to a business's expectations.
