Distributed Teams: Transferring Knowledge

I had observed that some of the industries I had previously worked, have had a high turnover rate resulting in a constant  influx of new team mates entering and exiting different phases of the projects. With these high-knowledge professionals transitioning the Organizational Intelligence (OI) acquired during the projects/operational activities is lost with their departure. However, most businesses do not have a planned knowledge transfer process resulting in a loss of OI.  

This makes me ponder - how should businesses prepare for these unplanned exits?  I read this article that shares a few great ideas to retain OI. For more details check it out: http://linkd.in/1xS8AAS
