Advanced uses of Excel often seem to depend upon someone within the organisation having specialist knowledge.
When I worked on the railways, and had to book taxis for customers left stranded by operational problems, we had to enter all of the information (such as the name of the taxi driver, the journey undertaken and the reason for using a taxi) onto an Excel spreadsheet. Then, as if by magic, that was converted into a form (which looked like an order form, rather than a spreadsheet) to give to the driver. At the end of each day we then had to email our updated spreadsheet through to the accounts department.
Unfortunately a simple keying error (such as leaving a field blank or using the incorrect type of input) was enough to get Excel to throw a wobbly, when it would then refuse to print the latest form and simply 'lock up' completely.
Given that I (or one of my colleagues) would typically be trying to enter the data into Excel while simultaneously answering four phones, handling radio messages, dealing with a dozen taxi drivers (all waiting for their paperwork), trying to placate twenty irate passengers and still despatching trains efficiently, errors weren't exactly uncommon! (Therefore irate taxi drivers, doubly-irate customers and panicking station supervisors weren't exactly uncommon either!).
We repeatedly referred the Excel problems back to head office, only to be told "Sorry, the woman who created the spreadsheet and its associated forms has left the company and nobody else knows enough about Excel to fix it!"
Grrr!
