When the HO is sufficiently large, it is very useful to provide a
specificphysical space (the SP Office), whichis the epicenter ofthe
planning process. Sometimes an ‘‘external facilitator’’ for SP is
contracted; this is the person in charge of organizing, motivating,
and networking all actions, giving them shape and connecting
them in time and space.When required by the circumstances,this
is a role often assigned to a consultant.
