managed by the respective decision domains, task command. And
the task command domains are part of the operational command
domain.
There is also a degree of hierarchy in the relationships between
the decision domains.
If, for example, several response operations are being executed
simultaneously, each with an incident commander who manages
his or her own decision domain, operational command. These re-
spective domains are at the same system level and consequent-
ly have equal status in the hierarchy. It is the decision domain,
system command, which manages and decides over them. In the
same way it is the decision domain operational command which
decides over the decision domains, task command. In situations
where task command occurs to different extents, it is the covering
decision domain that administers the imbalance between the task
command domains below it.
It is possible to an extent to identify the contents of each type
of decision domain – system command, operational command
and task command.Decision domains form
parts of each other and
cannot be lifted out of
their context.
