A product-service system (PSS), also known as a function-oriented business model, is a business model, developed in academia, that is aimed at providing sustainability of both consumption and production.
What is PSS?
Product Service Systems, put simply, are when a firm offers a mix of both products and services, in comparison to the traditional focus on products. As defined by (van Halen, te Riele, Goedkoop) "a marketable set of products and services capable of jointly fulfilling a user's needs". PSSes can be realized by smart products.
The initial move to PSS was largely motivated by the need on the part of traditionally oriented manufacturing firms to cope with changing market forces and the recognition that services in combination with products could provide higher profits than products alone. Faced with shrinking markets and increased commoditization of their products, these firms saw service provision as a new path towards profits and growth.
While not all product service systems result in the reduction of material consumption, they are more widely being recognized as an important part of a firm's environmental strategy. In fact, some researchers have redefined PSS as necessarily including improved environmental improvement. For example,(Mont)defines PSS as a "a system of products, services, supporting networks, and infrastructure that is designed to be competitive, satisfy customers' needs, and have a lower environmental impact than traditional business models" Mont elaborates her definition as follows: A PSS is pre-designed system of products, service, supporting infrastructures, and necessary networks that is a so-called dematerialized solution to consumer preferences and needs. It has also been defined as a "self-learning" system, one of whose goals is continual improvement.
"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.
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 in which transportation can be achieved simultaneously (as in car-pooling); one in which transportation can be achieved sequentially (as in car-sharing); and one in which transportation can be achieved eventually (rent-to-own).
Types of PSS
There are various issues in the nomenclature of the discussion of PSS, not least that services are products, and need material products in order to support delivery, however, it has been a major focus of research for several years. The research has focussed on a PSS as system comprising tangibles (the products) and intangibles (the services) in combination for fulfilling specific customer needs. The research has shown that manufacturing firms are more amenable to producing "results", rather than solely products as specific artefacts, and that consumers are more amenable to consuming such results. This research has identified three classes of PSS:
- Product Oriented PSS: This is a PSS where ownership of the tangible product is transferred to the consumer, but additional services, such as maintenance contracts, are provided.
- Use Oriented PSS: This is a PSS where ownership of the tangible product is retained by the service provider, who sells the functions of the product, via modified distribution and payment systems, such as sharing, pooling, and leasing.
- Result Oriented PSS: This is a PSS where products are replaced by services, such as, for example, voicemail replacing answering machines.
Van Ostaeyen et al. criticize this typology for failing to capture the complexity of PSS examples found in practice. They propose an alternative that categorizes PSS types according to two distinguishing features: the performance orientation of the dominant revenue mechanism and the degree of integration between product and service elements. According to the first distinguishing feature, a PSS can be designated as input-based (IB), availability-based (AB), usage-based (UB) or performance-based (PB). The performance-based type can be further subdivided into three subtypes:
- Solution oriented (PB-SO) PSS: (e.g. selling a promised level of heat transfer efficiency instead of selling radiators)
- Effect oriented (PB-EO) PSS: (e.g. selling a promised temperature level in a building instead of selling radiators)
- Demand-fulfillment oriented (PB-DO) PSS: (e.g. selling a promised level of thermal comfort for building occupants instead of selling radiators)
According to the second distinguishing feature, a PSS can be designated as segregated, semi-integrated, and integrated, depending on to what extent the product and service elements (e.g. maintenance service, spare parts) are combined into a single offering.
The following existing offerings illustrate the PSS concept:
- Xerox' pay-per-copy model for selling office equipment
- Rolls-Royce's Power-by-the-Hour service package for aircraft engines, whereby maintenance, repair and overhaul services are charged per hour of flight
- Atlas Copco's Contract Air service, whereby air compressors are sold per m³ of compressed air delivered
- Philips' pay-per-lux model for selling lighting equipment, whereby customers pay for a promised level of illuminance in a building
- Michelin's fleet management solution whereby truck tires are sold per kilometer driven
Impact of PSSes
Several authors assert that product service systems will improve eco-efficiency by what is termed "factor 4", i.e. an improvement by a factor of 4 times or more, by enabling new and radical ways of transforming what they call the "product-service mix" that satisfy consumer demands while also improving the effects upon the environment.
van Halen et al. state that the knowledge of PSS enables both governments to formulate policy with respect to sustainable production and consumption patterns, and companies to discover directions for business growth, innovation, diversification, and renewal.
Tietze and Hansen discuss the impact of PSS on firms' innovation behavior identifying three determinants. First, product ownership is not transferred to the customers, but remains with the PSS operating firm. Second, the purpose of a product is different if it is used within PSS solutions than compared to the purpose of products in classical transaction based business models. When offering PSS, products are used as a means for offering a service. Third, the profit function of PSS operating firms differs substantially from profit functions of firms that develop, manufacture and sell their products.
From a manufacturer's perspective, the business potential of a PSS is determined by an interplay of four mechanisms: cost reduction, increased customer value, changes to the company's competitive environment and an expansion of the customer base.
