The fundamental level is the core benefit: the service or benefit the customer is really buying. A hotel guest is buying rest and sleep. Marketers must see themselves as benefit providers.
At the second level, the marketer must turn the core benefit into a basic product. Thus, a hotel room includes a bed, bathroom, and towels.
At the third level, the marketer prepares an expected product, a set of attributes and conditions buyers normally expect when they purchase this product. Hotel guests expect a clean bed, fresh towels, and so on.
At the fourth level, the marketer prepares an augmented product that exceeds customer expectations. In developed countries, brand positioning and competition take place at this level.
At the fifth level stands the potential product, with all the possible augmentations and transformations the product or offering might undergo in the future. Here companies search for new ways to satisfy customers and distinguish their offering.
