Vendor Selection

Parameters to consider

•                 •  Range of products/services provided  
•                 •  Quality of products/services provided  
•                 •  Responsiveness  
•                 •  Dependability of Supply

•                 •  Capacity  

..and for strategic ones:

• Potential for Innovation • Ease of doing business • Willingness to share risk • Long-Term commitment to supply • Ability to transfer Knowledge

Rule:

• Supplier A gets 75% of the business • Supplier B gets 25% of the business

Advantages:

•                 •  Obtain scale economies from supplier “A”  
•                 •  Obtain security by having supplier “B”  
•                 •  Tell supplier “A” that they can increase their share by outperforming supplier “B” in terms of quality or cost  

Why the need to reduce the supply base?

• 1.  To reduce costs.

Firms understand that having fewer suppliers improves their competitive position by:

– Cutting their costs; and – Improving the product.

• Operational costs can be reduced – Fewer suppliers = less work to run on day-to-day basis
