EW TECHNOLOGY is introducing the possibility of process, procedure, and costeffective improvements in the way we do business.However, along with these possibilities lie great dangers.There have been many instances of largescale and costly failures, particularly when wholesale replacement of existing systems has been advocated.One large commercial airline, for example, had to scrap a large system development after some $50 million had been spent, in favor of returning to their original system with a strategy of slowly introducing incremental change.This presentation discusses an approach to integration pioneered by the Volpe Center and US Air Mobility Command (AMC).The Broker System is based on the concept of "brokering" data between existing systems.The Broker does not create new data, but relies on the impact that bringing together data that exist on disparate systems can have on the way that an organization does business.Broker is about reuse, incremental change, and the concept that in today's world there is no shortage of data, but often a scarcity of information resulting from the data.
