每日原则：金字塔塔尖上的人应当有管理直接下属的技能和专注力

A few years ago, someone at Bridgewater proposed that our facilities group (the people who take care of the building and grounds, food service, office supplies, etc.) should begin to report to our head of technology because of the overlap in the two areas (computers are a facility too, they use electricity, and so on). But having the people who are responsible for janitorial services and meals report to a technology manager would be as inappropriate as having technology people report to the person taking care of facilities. These functions, even if they're considered "facilities" in the broadest sense, are very different, as are the respective skill sets. Similarly, at another time, we talked about putting the folks who work on client agreements under the same manager as those who do counterparty agreements. But that would have been a mistake because the skills required to reach agreements with clients are very different from the skills required to reach agreements with counterparties. It would be wrong to conflate both departments under the general heading of "agreements," because each calls for specific knowledge and skills.
