Most businesses don't get the information they want from their existing systems. Some ask IT to write a report [which usually takes too long]. Others create spreadsheets that let users do what they want, but at what price. Spreadsheets are inefficient and not completely reliable: errors can happen when re-keying in data or there can be calculation errors. There is no audit trail on changes so mistakes may not be detected. Further, spreadsheets are typically not shared across an organization and they are not updated as things change. So, decisions are made with inaccurate information.
