Keep scale in mind. Your goals must be the right size to warrant the resources that you allocate to them. An organization might not be big enough to justify having both a sales and an analytics group, for example. Bridgewater successfully evolved from a one-cell organization, in which most people were involved in everything, to a multi-cellular organization because we retained our ability to focus efficiently as we grew. Temporarily sharing or rotating resources is fine and is not the same as a merging of responsibilities. On the other hand, the efficiency of an organization decreases as the number of people and/or its complexity increases, so keep things as simple as possible. And the larger the organization, the more important are information technology management and cross-departmental communication.

Organize departments and sub-departments around the most logical groupings based on “gravitational pull.” Some groups naturally gravitate toward one another. That gravitational pull might be based on common goals, shared abilities and skills, workflow, physical location, and so forth. Imposing your own structure without acknowledging these magnetic pulls will likely result in inefficiency.

Make departments as self-sufficient as possible so that they have control over the resources they need to achieve their goals. We do this because we don’t want to create a bureaucracy that forces departments to requisition resources from a pool that lacks the focus to do the job.
