A DECISION-MAKING EXERCISE FOR BUSINESS MARKETING
This exercise is designed to introduce undergraduate students to decision making in the context of organizational buying.
Several distinctions of organizational buying, compared to consumer 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 chose. 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, evaluation of decisions in a systematic, “rational” way is sometimes different from consumer buying (e.g.,
impulse purchases).
Part B: Group Evaluation – The second part of the exercise involves group decision making. Arrange students in
groups of two to four persons and have them evaluate these decisions again, but this time they all must agree on the point
allocations among suppliers. In discussing group solutions, the instructor may ask if there was any conflict and if so, how
it was resolved. If the group’s decision was very different from an individual’s original evaluation, the students may
discuss the dynamics of the decision-making process in how preferences were changed. This part of the exercise
illustrates concepts such as a buying center, roles of members in group decisions, and conflict management and
resolution.
