Suw Charman over at Corante has a fantastic case study (PDF download - 2.3 Mb) examining the use of blogs for a competitive intelligence project within a large European pharmaceutical group. It's a little heavy on pushing the software used, Traction TeamPage, but then again they are the sponsor.

Key quote:

Competitive information is always very unstructured and comes in lots of different ways — through the internet, internal sources, and various other ways. Using blogs to organise the data is quite effective because it doesn't impose too rigid a structure where we need some inherent flexibility.

I think I know who the company is, but if I were their CIO I'd be making sure everyone knew it was my organisation.

I'm sending it to everyone in our Healthcare and Change & Internal Communications practices.
