Spreadsheet Accuracy Matters

Spreadsheets are great, they are my favourite go-to way of dealing with data – BUT there are drawbacks; well actually ONE major drawback – spreadsheets are very very prone to human errors!

The percentage of spreadsheets that are inaccurate is alarming, there are plenty of stories on the web outlining problems with spreadsheet errors;

When people undertake simple mechanical tasks, such as typing, they make undetected errors in about 0.5% of all actions.
When we do more complex logical activities, such as writing spreadsheets, the error rate rises to about 5%.

These are some really useful ways to improve your spreadsheet accuracy…. Some are obvious, some I haven’t thought of before and am now using everywhere (using a single ‘error-checking-sheet’ is an awesome idea).
