A coordination study, sometimes known as protective device coordination analysis, protection study and similar terms, is an “attempt” to select and set devices to minimize the extent of an outage when a fault or overload occurs. Ideally only the device closest to the fault should operate and clear with the other devices remaining closed. This minimizes the extent of the outage.
As Jim states, perfect coordination is almost impossible to achieve but you can greatly improve it by making appropriate compromises with selectivity to optimize coordination for the overall system.

Understanding coordination and protective devices time current curves is also an important part in defining the arc duration for an arc flash study.
