Traditionally,hierarchicalmanagementhasofferedameansofdirectinghumanactivity.9Entitiesasdiverseasgovernments,religiousinstitutionsandcorporationsusecentralizedmethodstogovernresources,territoriesandcommunities.Utilizinginnovationssuchasjoint-stockcompanies,centralizedorganizationshavebecomesomeofthemostpowerfulandeconomicallyvaluableenterprisesevercreated.
Yetcentralizationisnotwithoutitscosts.Withasmallminorityincharge,centralizedentitiestendtomakedecisionsopaquelyandconsolidatepoweratthetop.Theoverheadsofcentralizedmanagementcanbeconsiderable.Moreover,centralizedorganizationsmayoveremphasizenarrowgoals,likemaximizingshareholderprofits,attheexpenseofbroaderconsiderationssuchascontributingtoeffortstoaddresstheclimatecrisis.10
