Mark, You're still thinking too technically. Long before we can discuss what qualities an IT system may have, we need to decide what functionality is needed by the business and why, how it will fit in with the rest of the business, and how much money we can afford to spend on that functionality. If we decide that an IT system is needed, we can then explore whether to simply offload the requirement onto an external supplier, whether to purchase an off-the-shelf package or whether to develop our own in- house solution. As I think I described, the concepts of service orientation are very useful in guiding these decisions. Regards, -Mike "The Suit" Glendinning.
