Customer Expectations. It is clear that when customers transact business with a supplier they have numerous expectations, many of which revolve around the supplier's basic logistics service platform; that ts , they have expectations regarding availability, operational performance, and service reliability. Frequently, they have in place formal programs to monitor supplier performance with respect to each of these dimensions of logistics performance. In a pioneering study Parasuraman, Zeithaml, and Berry identified 10 customer expectations that form a useful framework for evaluating logistics impact. Table 3.2 uses their framework to conceptualize specific logistics-based expectations.
