In corporate purchasing,

            competitive scrutiny is typically

            limited to suppliers of items that are

Line     directly related to end products.

  (5)      With “indirect” purchases (such as

computers, advertising, and legal

services), which are not directly

related to production, corporations

often favor “supplier partnerships”

(10)     (arrangements in which the

purchaser forgoes the right to

pursue alternative suppliers), which

can inappropriately shelter suppliers

from rigorous competitive scrutiny

(15)     that might afford the purchaser

economic leverage.  There are two

independent variables—availability

of alternatives and ease of changing

suppliers—that companies should

(20)     use to evaluate the feasibility of

            subjecting suppliers of indirect

            purchases to competitive scrutiny.

This can create four possible

situations.

(25)           In Type 1 situations, there are

many alternatives and change is

relatively easy.  Open pursuit of

alternatives—by frequent com-

petitive bidding, if possible—will

(30)     likely yield the best results.  In

Type 2 situations, where there

are many alternatives but change

            is difficult—as for providers of

employee health-care benefits—it

(35)    is important to continuously test

the market and use the results to

secure concessions from existing

suppliers.  Alternatives provide a

           credible threat to suppliers, even if

(40)    the ability to switch is constrained.

In Type 3 situations, there ate few

alternatives, but the ability to switch

without difficulty creates a threat that

companies can use to negotiate

(45)     concessions from existing suppliers.

In Type 4 situations, where there

are few alternatives and change

is difficult, partnerships may be

unavoidable.

Which of the following can be inferred about supplier partnerships, as they are described in the passage?
