buying, can be made by using this exercise. For example, differences in decision criteria are
highlighted, and individual versus group decision making can be demonstrated.
Procedure
The three decision evaluations represent different product categories in organizational buying—
office copiers, accessory goods that do not become part of the final product; painted sheet metal,
component parts; and an industrial boiler system, major equipment or a capital installation
(Lamb, Hair, and McDaniel 1992). Use of these three decisions illustrates the wide range of
products that may be procured by a buyer or purchasing agent.
Each exercise is designed so that there is no right or wrong answer. The “suppliers,” represented
by the attribute combinations, represent a pool of vendors from which the buyer can choose. The
display of the nine suppliers is a fractional factorial design that has each of the four decision
variables (price, quality, delivery, service) represented in orthogonal combinations. The
expression of these attributes varies in order to be decision-specific. For example, quality for the
boiler system is expressed in terms of pollution control, while quality for copiers is expressed as
the number of features available.
Part A: Individual Evaluation
A helpful class exercise is to have students role-play as organizational buyers to work through
these decisions individually. Students are instructed to read the decision context statement and
then examine the nine “vendors” described by each block. For example, in the copier decision,
vendor N offers a copier that is priced at $3,500, has the A-level feature package (see bottom of
decision), requires two hours of maintenance (downtime) per month, and can be delivered in two
weeks. Students then should cross out any vendors that are not acceptable—for whatever reason.
Of the acceptable vendors, students divide 100 points to represent how they want to source the
decision. For example, one copier vendor could be given all 100 points, or the buyer (student)
can use a multiple sourcing strategy by dividing the points among several (50/50, 70/30,
40/40/20, etc.).
At this point, the decision evaluations illustrate the concepts and variables that organizational
buyers use in selecting suppliers. After completing the decision individually, students can be
asked to offer their “solutions” to the buying decision. Since there is no right or wrong way to
complete the exercise, students will differ in their solutions. Discussion of several of their
solutions illustrates the concept of trade-offs in buying and the fact that organizational buyers
have different levels of expectations in buying. What is important to one buyer may not be as
important to another. In addition, the evaluation of decisions in a systematic, “rational” way is
sometimes different from consumer buying (e.g., impulse purchases).
