The document discusses how a company that sells microwave ovens could add service elements to their business model to combat falling profits from increased competition. It describes strategies for designing product-service systems (PSS), where services are integrated into product design and ownership models. A PSS could maintain contact with customers and offer supplies, maintenance, upgrading, and disposal to deliver utilization of the product as the service. This shifts the business model from a focus on products to maximizing usage. The document suggests the microwave oven company could target a market segment by offering lease, rental, or pay-per-use models for microwaves to create new patterns of flexible usage and ownership.
