Q3) Can spreadsheets be used to assist business functions in really large organizations?
A3) Spreadsheet based business solutions work best when the organizations data can be stored on a single "working" spreadsheet and they are thus most suited solving every day, organisation wide, business problems in small to medium sized companies where the number of users of a single database spreadsheet is small. Business tools that need to support multiple users simultaneously are not normally best solved using spreadsheets. This, of course, doesn't mean that spreadsheets are not suited to large organisations! Indeed there are many smaller business problems in large organisations for which spreadsheets offer the quickest and best possible solution.
