Give me a big cigar - I get it!
Each of the research teams on the left is pursuing a series of categories of research (the little blue-square icons) [see NOTE below] and they will contribute X amount of progress in these fields regularly. In addition, each of these teams can "focus" on a specific short-term project (ergo the "replace" button and the available techs menu to the right). Probably when a team is "focused", it contributes less (or none) to its basic blue-square fields (ergo the "no project assigned" notification, which shows that all efforts of this team are directed towards "general" [blue-square] fields).
Now if you look at the blue-square icons and associate them with their companies, it makes sense.
Can I be the first to say that this is a GREAT compromise solution between Vicky's horrible tech tree and HOI's wonderful-but-complex system? Nice!
NOTE: whether the categories of research available to each team are hardcoded or not is open to question. I would suspect they are, since this would tend to create nation-specific militaries, which has been hinted as a feature of HOI2. However, you can moderate the historical paths of each nation's militaries by heavily managing the special projects of each team.
ALSO: I suspect that when a team is assigned a special project within its blue-square icon areas of expertise, that special project will come much faster than if it is assigned a project outside of its expertise.
THIS IS AWESOME!
