The Industrial Buying Process
According to Johnston andBonoma(1981), "No two buying decisions in any given company are
likely to be exactly alike, nor will any two companies follow exactly the same procedures in even highly
similar purchase situations" (p.146). However, there may be many general patterns of interaction and
social behavior that have similarities, even across moderately different purchase situations, according to
these authors.
It is for this reason that the study of the buying process and those involved in it are considered
important for this study. Several researchers in industrial buying behavior (IBB), also known as
organizational buying behavior (OBB), have provided contributions for the mapping of the decision
process that are common in many industrial markets. Such scholars include: Cyert, Simon, & Trow, 1956;
Webster, 1965; Robinson, Faris, & Wind, 1967; Webster & Wind, 1972a; Hillier, 1975; Wind, 1978; Vyas
& Woodside, 1983; and Bunn, 1993. This purchasing process begins "from the time at which a need
arises for a product or service..." (Wind & Thomas, 1980,p. 242).
In writing about the five dimensions of the industrial adoption process, Ozanne and Churchill
(1971) present five stages that an industrial buyer goes through in adopting (i.e. deciding to purchase)
an industrial product The model takes into account explanatory variables such as the identity of the firm
and the identity of the decision group involved. The information sources obviously play an important
role and are of the main interest for this study. Such marketing communication tools as advertising and
brochures (considered to be "impersonal sources" of information) are more a part of the early stages of
creating awareness and interest. In the latter stages of evaluation, trial and adoption, utilizing such tools
as the writing and presentation of a formal proposal, reports from other users/other firms, as well with
personal contact with dealers and salesmen (personal selling). These are considered to be the
"personal" sources of information for the buyer.
Ozanne, et al., concluded that a wide variety of information sources are encountered in the
industrial adoption process. The authors first discussed these information sources being "first separated
into personal and impersonal categories, and then into subcategorize of personal influence, personal
selling, advertising, publicity, sales, technical sources, and previous experience" (op. cit.,p. 327, with
reference to Ozanne & Churchill, 1968,p.356). Patti, Harley and Kennedy (1991, pp. 40-41) also provide
detailed information of the various information sources used during the industrial buying process. Their
work discusses only certain commercial forms of marketing communication tools, with an emphasis on
advertising and the style of advertising that should be considered in each stage of a six-step buying
process.
This six-step process is:
1. Problem or need recognition: In this first step of the buying process, the buyer recognizes the
need for a particular product or service, or identifies a problem that can be resolved through the
purchase of a product (or service). In business-to-business settings, the need for a product is often
identified by production or manufacturing engineers and management, rather than by purchasing
agents. For the purchase of newly designed products, raw materials, component parts and services
related to these products, purchasing personnel often play a bigger role in the specification of product
and supplier. It is in this stage that such marketing communication tools are important: "Advertising, as
well as other forms of promotion, can play an important role in this first step of the purchase process.
Often, advertising demonstrates how products or services can solve problems, and by doing so,
it can spark the interest of buyers in solving known, existing problems, or in fulfilling the continual need
for improved efficiency.
2. Search for appropriate solutions: After buyers have identified a problem or need for a
product, there begins a search for appropriate solutions. "The role of advertising in this stage of the
buying process is to position the advertiser as a provider of an attractive solution.. .the goal of the
advertiser is to become one of the alternative suppliers".
3. Evaluation of alternative solutions: It is in this stage that Patti, et al., add that buyers are
often described as being cold, analytical, and in the process of evaluating such factors as product
specifications, price, terms of payment, delivery date, and service. Advertising to the buyer during these
stage, "can help a supplier generate a higher perceived value by stressing superiority of product
attributes and quality of performance...it is often effective during this stage of the buying process...to
communicate confidence and reliability.
4. Purchase decision: This stage involves two decisions: a) make a purchase; b)select an actual
supplier. These two decisions usually involve more people in the company than any of the other steps in
the buying process. This is one reason that smart business-tobusinessmarketers advertise in several
different publications in order to talk directly with the many known and unknown influences on a
purchase, on their own terms and in the publications they read.
Purchase implementation: Involves the actual act of placing the order and making arrangements
for shipping, delivery, and payment. "Although advertising can help assure buyers that the supplying
company is skilled and experienced in facilitating purchase implementation, these tasks are usually
placed in the hands of the marketer's personal selling staff.
6. Postpurchase evaluation: After the purchase has been completed, the buying firm then has
the opportunity to test the performance of the product purchased and evaluate it. "Because the early
stages of the 27 buying process involve so many people, the number of people who evaluate a post-
purchase decision must be at least as large. Advertisers need to keep in mind that once a product or
service has been purchased, users — people who perhaps up to this point had little or no influence on
the purchase — will often express their level of satisfaction. Advertising, of course, cannot overcome
significant flaws in a product or service. However it can:
• help assure that they made an effective selection;
• help convince buyers of the satisfaction of other buyers (customers of the supplier); and
• help convince buyers that the advertiser is ready to stand behind the product/service
purchased. Advertising at this stage can often include case histories, corporate image advertising, as well
as advertising that shows a commitment to quality, problem solving and customer service. The above
stages demonstrate that, in addition to personal selling, other marketing communication tools, such as
media advertising, are used during all the stages of the buying decision process in industrial markets.
Other research on the buying process has provided a similar series of steps as those provided by Patti, et
al.
The buying process developed by Robinson, Faris, and Wind (1967), referred to as the Buygrid
Framework has been greatly utilized and often cited in IBB research (e.g. Wind & Webster, 1972;
Johnston &Bonoma,1981; Mattson, 1988), making it a major contribution to the understanding of IBB.
The value of the buying decision process developed by Robinson, et al., is that it also includes what
these researchers refer to as "Buy Classes." These three factors are what determine, in each stage of the
buying process, the following: The newness of the problem; the information requirements for that
stage; and the consideration of new alternatives. We will of course focus on the information
requirements.
The Buy Classes, as presented by Robinson, et al., include:
• "New task: When a purchaser is buying an industrial product or service for the very first time;
• Modified rebuy: Involves the situation where the buyer wants to modify product
specifications, price, and other terms;
• Straight rebuy: Is the buying situation where the purchasing department reorders on a routine
basis" (op. cit.,p.164) When combined with these three buy classes, the eight buy phases developed by
Robinson, et al., becomes what is known as the Buy grid Framework, representing the correlation
between the stages of the buying process (Buy Phases) and the different buying situations.
