and again here it is, among other things, the situation that deter-
mines the length of the scale.
Longer time scales set limits for shorter ones. Short time
scales cannot cover events stretching further into the future
than the longest time scales within one and the same decision
domain. Time scales in subordinate decision domains also cannot
be longer than the longest time scales in the decision domains
above them. If such should occur for some reason, the work of
the subordinate decision domain cannot really be considered to
be in line with the work of the decision domain above it. The sub-
ordinate decision domain cannot, in this situation, with certainty
handle its authority and there is an obvious risk of the system
being reactive and only being able to handle the current situation.
It is important that superior decision domains are able to broaden
their horizons and handle longer time scales than the domains
under them. System command must be organised and run in such
a way as to not restrict the time scales of operational command,
and operational command must be organised and run in such a
way as to not restrict the time scales of task command.System levels and
