Requirements for Effective Requirements for Effective SP(Strategic Partnering)SP(Strategic Partnering)

• Advanced information systems• Top management commitment

– Information must be shared– Power and responsibility within an organization

might change (for example, contact with customers switches from sales and marketing to logistics)

• Mutual trust– Information sharing– Management of the entire supply chain– Initial loss of revenues

Page 11: Vendor managed inventory

Important SP IssuesImportant SP Issues• Inventory ownership:

– Retailer owns inventory– Supplier owns the goods until they are

sold (consignment)• Why would a firm do this?

• Performance measures: Fill rate, inventory level, inventory turns

Page 12: Vendor managed inventory

Important SP IssuesImportant SP Issues• Confidentiality• Communication and cooperation

– When First Brands started partnering with Kmart, Kmart often claimed that its supplier was not living up to its agreement to keep two weeks of inventory at all times. It turned out that this was due to the fact that the two companies employed different forecasting methods.

Examples of SP Successes Examples of SP Successes and Failuresand Failures

• Western Publishing-Golden Books:– Western Publishing is using VMI for its Golden Books line

of children’s books at several retailers.– POS data automatically triggers re-orders when

inventory falls below a reorder point.– This inventory is delivered either to a distribution center,

or in many cases, directly to the store.– Ownership of the books shifts to the retailer once

deliveries have been made.
