GE Healthcare (formerly GE Medical Systems) developed InSite to remotely monitor its medical equipment in order to reduce service costs and increase users' Evidence-based Service: companies use big data analytics to provide the actual saving and further develop a service contract for customer to pay for part of the savings. There are many methodologies on PSS design. Dominant Innovation system uses an Innovation Matrix to identified gaps from customer's fear, not needs based on scenario-based path finding. A new value-chain ecosystem can be further developed to link these gaps between two invisible spaces. For example, John Deere developed Agric Service business based on the customers' worries on soil related issues. It integrates sensors with GPS to develop cognitive site map about soil content to optimize crop yields.] In recent years, PSS has been further integrated with big data analytics for accelerated innovation. Other technologies such as prognostics, health management and cyber-physical systems have further created service innovation technologies for PSS. For example, Alstom has been developing Train Tracer technologies since 2006 and is implementing Health Hub system for its transport fleets. Servicizing "Servicizing" is a transaction through which value is provided by a combination of products and services in which the satisfaction of customer needs is achieved either by selling the function of the product rather than the product itself, or by increasing the service component of a product offer. The concept is based on the idea that what customers want from products is not necessarily ownership, but rather the function that the product provides or the service the product can deliver. This means that the provider of "servicizing solutions" may get paid by the unit-of-service (or product function) delivered, as opposed to the (more traditional) unit-of-products sold. See service economy for more on the servitization of products. Types One type of servicizing solutions is based on transactions where payment is made—not for the "product"—but for the "product-service package" (part of PSS) which has been sold to the customer. This servicized purchase extends the buying transaction from a one-time sale (product acquisition), to a long-term service relationship (such as in the case of a long-term maintenance-free service contract). Another type of servicizing may be a strategy for providing access to services for people who cannot afford to buy products outright. For example, in the case where auto ownership is economically unfeasible, creative servicizing offers at least three possible solutions: one
