WarehouseManagementSystems（WMS）.

Theevolutionofwarehousemanagementsystems（WMS）isverysimilartothatofmanyothersoftwaresolutions.Initiallyasystemtocontrolmovementandstorageofmaterialswithinawarehouse,theroleofWMSisexpandingtoincludinglightmanufacturing,transportationmanagement,ordermanagement,andcompleteaccountingsystems.Tousethegrandfatherofoperations-relatedsoftware,MRP,asacomparison,materialrequirementsplanning（MRP）startedasasystemforplanningrawmaterialrequirementsinamanufacturingenvironment.SoonMRPevolvedintomanufacturingresourceplanning（MRPII）,whichtookthebasicMRPsystemandaddedschedulingandcapacityplanninglogic.EventuallyMRPIIevolvedintoenterpriseresourceplanning（ERP）,incorporatingalltheMRPIIfunctionalitywithfullfinancialsandcustomerandvendormanagementfunctionality.Now,whetherWMSevolvingintoawarehouse-focusedERPsystemisagoodthingornotisuptodebate.WhatisclearisthattheexpansionoftheoverlapinfunctionalitybetweenWarehouseManagementSystems,EnterpriseResourcePlanning,DistributionRequirementsPlanning,TransportationManagementSystems,SupplyChainPlanning,AdvancedPlanningandScheduling,andManufacturingExecutionSystemswillonlyincreasethelevelofconfusionamongcompanieslookingforsoftwaresolutionsfortheiroperations.

DoYouReallyNeedWMS?

WMSwillincreaseinventoryaccuracy!

TheReality:
