Final answer:
The extended P's of service marketing mixes include People, Physical Evidence, and Process, critical for product differentiation and influencing customer perception and behavior through the physical environment and intangible aspects.
Step-by-step explanation:
The extended P's of service marketing mixes are People, Physical Evidence, and Process. These elements are critical in differentiating a product or service from its competitors, beyond the traditional marketing mix that includes Product, Price, Place, and Promotion. The concept of place-product-packaging, for example, illustrates how the physical environment can influence customer perception and behavior. In the context of marketing, businesses like chain stores or restaurants use consistent architectural designs and other physical aspects to create a familiar and predictable experience for customers. Location is also a key aspect, as it can greatly impact sales volume. For example, a gas station at a busy intersection is likely to sell more gas due to higher traffic. Similarly, suppliers often find advantages in situating close to their markets, like an automobile factory. Intangible aspects like a brand's reputation, guarantees, and advertising contribute significantly to product differentiation as well.
