Summary of information provided
Spreadsheets are notoriously difficult to control. The very
features that make them so useful, also make them risky i.e.
flexibility, ease of use and transferability. Hence the new
requirements per SoX legislation. Don't feel happy if
you don't live or deal with the US. This legislation, maybe
under another name, will be coming to your town soon. So you may as
well prepare now!
Below are some of
the controls that need to be considered and implemented for
spreadsheets. You can
click on each one to get practical ideas of how to address them
using only Excel’s inbuilt tools and features.
Keep in mind that depending on the importance of
the spreadsheet, you may need to introduce more stringent
controls, but these suggestions will show you how to use the tools you
already have in the most effective manner. At the very least,
all spreadsheet users in the organization should know this.
