4.3.1 Business buying processes
Figure 4.2 provides a useful model of business buyer behaviour that we can contrast with our consumer black box model in Figure 4.1.

Consider this
Compare the above model with the black box model of consumer behaviour in Figure 4.1. What do you think are the main similarities? What do you think are the main differences?
The basic difference between the two models is in the middle segment: a black box in the case of consumers, an organisation in the case of business markets. We will be giving our attention to the two main components of the middle segment: the buying centre and the buying decision process. Table 4.2 is included here to help remind you of some of the differences between business and consumer markets.

The buying centre concept is useful in understanding the various influences on the business buying process. The business marketer, such as a port, terminal or shipping service, needs to be aware that in any purchasing situation there is not only the buyer, but users, influencers, deciders and information gatekeepers as well. These are discussed for you on pages 292-293 of Kotler et al. (2004). All these roles comprise the buying centre, and its size and composition vary depending on the nature of the purchase as well as the type of business.
The buying decision process has a number of major steps that vary from text to text. The following table, as you will observe, has close counterparts to consumer buying.

Now that you have thought about the steps in the business decision-making process, and given that they are reasonably self-explanatory, we will not address them further. Instead turn to the following reading which will also describe the three main types of decisions which business buyers make, namely:
- new task (or new buying)
- modified rebuy
- straight rebuy.
The reading will also elaborate on what we have discussed above and includes detail on four approaches for evaluating and buying products.

Do not forget that business buying is done by individuals or groups of individuals. Thus, social and psychological factors such as culture and personality do play a part. An astute marketer must endeavour to understand the interpersonal dynamics within the buying organisation and between it and his/her own organisation.
