Explanation:

In order to understand how agencies functiong in emergencies, is important to note the features of command, and coordination.

Command is defined, as that internal operations of personnel and resources of a determined agency, that operates vertically, with jerarchy.

Whereas coordination brings closer agencies and resources to garantee an effective and quick response to emergencies.

A standard called ICS formed as an approach to coordination, command and control responses that have a common criteria withini which people from multiple agencies can work effective.

Sometimes authority is delegated, and other procedures can be further explained in Emergency Operations Plan for each agency.

if interdependence implies a two-way dependence, and if each partner is equally dependent on the other for success, then there is an equal commitment to the making the partnership successful. the advantage is sustainability of the relationship, the disadvantage is that decisions are "democratic" and therefore may take longer to reach and more likely to be a compromise (which is not always the best solution). as the interdependence moves away from equality, the decisions become more influenced by the more independent partner. in the extreme the relationship becomes more dictatorial and more like "master-slave". generally the relationship has less commitment in both directions and is more likely to be temporary.

if one generalizes (and one shouldn't), equity partnerships, which is probably what is implied by interdependence, can be slow to progress or change but durable. the extreme alternative, independent-dependent partnerships tend to be efficient but more fragile.

hope this but you will have to site your own evidence. : )
