Bottom up or Not? It Depends on the Situation
Brett E Holdeman, SIG Leader
I agree with both of you, Mohammad and Agnes. It depends greatly on the viewpoint of the type(s) of decisions being considered and the relative health of the organization, insofar as how badly it needs change - drastically or incrementally.
Sometimes a quick decision to thwart financial bleeding is in order, and other times, wholesale change is needed which each level of the hierarchy should be allowed to weigh in on is the preferred method.
If leadership is worth their salt, they'll successfully discern which situation requires which approach. Otherwise, new leadership or drastic change may be necessary, which will undoubtedly bring change, whether desired or not.
