The network of people flows through the network of jobs relatively quickly. Who’s where in the organization can change almost daily. However, the overall pattern of flow into and out of the organization is relatively predictable—except when there are reorganizations and growth spurts

The network of positions usually changes relatively slowly, but change it does. Organizations start small and grow job by job in a zig-zag process of development. Mature orgs go through periods of re-organization where many positions may be quickly changed, added, or deleted

Changes in the base enterprise data of people and/or positions are assumed. Each base map is revised on a periodic schedule, e.g., daily or monthly. Layers need to be synchronized against new versions of the base.
