I think Bomber has it almost right!
The trouble in GF is that the users of such systems (and I am not being specific about AIMS but most new systems introduced) are not prepared to change the way they work and their departmental managers are too soft to speak out!
They select a new system and give the provider a list of 'customisations'; essentially these changes make the new software very much like the old, consequently, a wad of money is spent on a bright shiny new package and that's about it! The users get what they want, IT see themselves as 'consultants only' so that they don't have to take any responsibility, departmental managers are not held accountable (is anyone in GF?) and the airline gets even more broke in the process! <img src="frown.gif" border="0">
