accountant’s role in IT implementation

Hello:) I am conducting a mass survey about IT/IS opinion about accountant/accounting profession involvement in IT/IS implementation. It would be very grateful if you could give me some opinion on some issues below:
1) To what extent have you encountered accountants involvement in IT implementation?
2)Do we need them to be in the implementation team? why and why not?
3)If they do involve, why do you think they involve? e.g. top management instruction.
4) Do they have the skills required to be part of the implemenetation team?

Other opinions are also vwer much welcomed. thank you.
