Yeah it works and you don't need support contracts and then:
- Fidelity's "Minus Sign Mistake": loss of $1.3 billion
- TransAlta "Clerical Error": loss of $24 million
- Fannie Mae "Honest mistake": loss of $1.3 billion
Then you get employee turn over where new employees don't get "arcane" knowledge passed down by people who left and took their spreadsheet foo with them.
Excel does not have "access control", "auditing", "change tracking". Just getting work done is not enough.
