Abstract

There are five major problems with spreadsheets:

  • The potential for errors.
  • Lack of security.
  • The absence of an audit trail.
  • The misperception that spreadsheets are not an enterprise resource.
  • Productivity issues.

We will consider each of these in turn, before considering some other management issues related to spreadsheets.

We have divided these into 'must have' and 'advanced' facilities, where the former are essential and the latter would be nice to have.
