So perhaps the compromise lies, as Block says, in finance being a weigh station of sorts. That's because it is most often the department that receives the requests to expense these services. Finance can discuss with IT the reason that departments feel a service is necessary, and it can explain the result that users are trying to achieve. Finance and IT together can then determine if the functionality can be found in-house. Finance might also have to take up the charge on behalf of departments to speed IT implementation based on need, thereby reducing the tendency of departments to go rogue.
