For example, for government, it is designing a system, process and infrastructure that allows the case officers/agents to visualize associative information from the background process of data mining and intelligent software processing. This way, they can see the dots as well as connect the dots. While the technology is not a big deal, setting up the infrastructure and process is. There are too many databases with different database structures. Anyway, my job is architecting such systems that would work. It does utilize some bleeding edge technology (fresh off the research labs).
For business, it is setting up a structure that converts data to knowledge so that the CEO level people who do not understand computers can use it to make the right decisions - for increased agility, profitability, revenue and stakeholder value. For example, CBRL uses a small set of this technology (since Nov.1999). You can check their stock and how it is doing vs. others. One company called Stage stores passed the offer and went Chapter 11. So did Global Crossing.
