The Case for an Inventory Optimization
Solution
Inventory Optimization solutions allow an organization to achieve a
balance between the most efficient investment in inventory and highest customer
service levels.
“One
such misconception is that existing enterprise resource planning (ERP) systems
can handle inventory management adequately. For small distributors not working
in complex environments, this may be true. Most ERP systems do count and track
inventory very well, and possibly even provide a basis for replenishment.
However, such systems can lack the sophistication required to take inventory
management to the next level, as well as the responsiveness necessary to handle
rapidly changing market conditions. Nor do they have the depth or strength to
evaluate and forecast inventory down to individual products and locations, which
is essential if you're going to squeeze out additional costs and increase
profits." (Source: S.Kilgore, Balancing Supply and Demand,
Forrester Research, March 2002)
ERP
vendors themselves have recognized this fact, and have recently started adding
advanced planning functionality as separate extensible modules to their core
product offerings. Inventory Optimization software recognizes that different
industries have different inventory profiles and requirements. That fast moving
retail items have different characteristics to slow moving items in automotive
spare parts. Inventory Optimization software have this functionality.
