This document discusses business markets, types of business buying situations, and the business buying process. It covers the following key points: 1. Business markets have fewer, larger buyers that are geographically concentrated with inelastic, fluctuating demand derived from another industry. Decision making is more complex and formalized with close, long-term buyer-seller relationships. 2. The major types of business buying situations are straight rebuy, modified rebuy, and new task. 3. The business buying process includes problem recognition, need description, product specification, supplier search, proposal solicitation, supplier selection, order routine specification, and performance review.
