Information and it's value chain

One of the topics I'm researching is the principles of the value chain and their impact to information inside enterprises. Somehow, every company today is like a big media conglomerate: they live for the content they create and use; they base their decisions on it; they invest massive amounts of money to improving it. Better said, in the technology to unbury it, to present it and to store it.

However, very little thinking is applied to the way information is created and used inside enterprises. I'm playing with this idea of the value chain of information compared to the industrial era concept of the physical value chain. Lean management techniques applied to the physical world have produced enormous improvements in corporate performance. Is there anything similar to be achieved in the world of information supply chain?
