Enhancing service requirements of technical product-service systems

Due to the integration of product and services as a new business model, product reliability and strategies for cost reduction at the early design stage have become important factors for many manufacturing firms. It is, therefore, critical at this phase to analyse the risk involved with Service Requirements noncompliance in order to help designers make informed decisions; as these decisions have a large impact on the Product Life Cycle (PLC). An investigation has been performed into how Service Requirements are analysed in a service orientated business to achieve reduced Life Cycle Cost (LCC) and improvements of existing Service Requirements. Weibull distribution and Monte Carlo principle have been proposed to do so; as they are considered as the most widely used in product reliability studies in the industry sector. A generic methodology for risk evaluation of failure to deliver a new product against Service Requirements is presented in this paper. This is part of the ongoing research project which aims to, apart from comparing current and targeted Service Requirements, it also facilitates an optimisation of them at the minimum risk of nonconformity

An Ontology for Product-Service Systems

Industries are transforming their business strategy from a product-centric to a more service-centric nature by bundling products and services into integrated solutions to enhance the relationship between their customers. Since Product- Service Systems design research is currently at a rudimentary stage, the development of a robust ontology for this area would be helpful. The advantages of a standardized ontology are that it could help researchers and practitioners to communicate their views without ambiguity and thus encourage the conception and implementation of useful methods and tools. In this paper, an initial structure of a PSS ontology from the design perspective is proposed and evaluated

Critical reflections on designing product service systems

In response to unsustainability and the prospect of resource scarcity, lifestyles dominated by resource throughput are being challenged. This paper focuses on a design experiment that sought to introduce alternative resource consumption pathways in the form of product service systems (PSS) to satisfy household demand and reduce consumer durable household waste. In contrast to many other PSS examples this project did not begin with sustainability benefits, rather the preferences of supply and demand actors and the bounded geographical locations represented by two UK housing developments. The paper addresses the process through which the concept PSS were designed, selected and evaluated, alongside the practical and commercial parameters of the project. It proposes the need for a shift to further emphasize the importance of the design imperative in creating different PSS outcomes that reorganize relationships between people, resources and the environment

Design Opportunities in Service-Product Combined Systems

This paper aims to examine recent research issues related to the integration of service and product in view of industrial design. Further, it attempts to identify new opportunities for further research regarding “product-servicization” vs. “service-productization”. In the continued efforts to provide the users with fuller experiences, one major trend is the blending of products and services. Much existing research seems to either present cases or propose frameworks regarding the ‘connection’, rather than ‘integration’ between products and services. Broadly, two major approaches seem to exist in this area: 1. product-servicization, 2. service-productization. The former generally indicates adding more services to existing products, whereas the latter generally refers to making services tangible and/or visible in the form of a product. However, findings of an extensive literature search conducted for this study suggest one important deficiency in dealing with service issues around the product: the ‘integration’ between the actual product design and service elements for supporting new service-product system. That is the rationale behind this research, an attempt to investigate the possibility for the integration of product design and service factors which could be embedded in the design of product itself in new service-product system. This paper is largely based on qualitative research. New design research opportunities are identified by qualitatively analyzing relevant literature, synthesizing the information and presenting some cases to support the main argument of the research. Design-led Service-Productization is not, and should not be re-arranging deck chairs on the Titanic. Rather, it should bring practical and tangible design issues related to new service-product system. Findings suggest that this approach could provide a new model of new product development integrated with a service scheme, which is a more proactive approach than “product-servicization”. Further development of this research could lead to establishing a framework for the Design-led Service-Product Integration.

State-of-the-art in product service-systems

A Product Service-System (PSS) is an integrated combination of products and services. This western concept embraces a service-led competitive strategy, environmental sustainability, and the basis to differentiate from competitors who simply offer lower priced products. This paper aims to report the state-of-the-art of PSS research by presenting a clinical review of literature currently available on this topic. The literature is classified and the major outcomes of each study are addressed and analysed. On this basis, this paper defines the PSS concept, reports on its origin and features, gives examples of applications along with potential benefits and barriers to adoption, summarises available tools and methodologies, and identifies future research challenges

Differences in forecasting approaches between product firms and product-service systems (PSS)

This paper examines the forecasting implications for Product-Service Systems (PSS) applications in manufacturing firms. The approach taken is to identify the scope of operations for PSS applications by identifying all the activities associated with the total cost of ownership (TCO). The paper then develops a revenue model for manufacturing firms providing PSS applications. The revenue model identifies three generic revenue streams that provide the basis for discussion on the differences in forecasting approaches between product firms and Product-Service Systems (PSS) in manufacturing firms. The forecasting approaches are different due to the nature of customer involvement in the service aspect of PSS applications. This necessitates an understanding of the customer service experience and the factors affecting this such as the service profit chain which links profitability, customer loyalty and service value to employee satisfaction, capability and productivity. The forecasting approaches identified raises forecasting challenges for each of the three generic revenue sources. These challenges vary from the difficulty in obtaining the service user’s viewpoint through to difficulties in determining market acceptance of PSS applications

An aesthetic for sustainable interactions in Product-Service Systems?

Copyright @ 2014 Greenleaf Publishing.Eco-efficient Product-Service Systems (PSS, in which the economic interest of the stakeholders involved in the offer continuously foster the optimisation of environmental resource consumption) represent a promising approach to sustainability. However, despite their potential win–win characteristics, the application of this concept is still limited. One key reason is that eco-efficient PSSs are often radical innovations and their adoption usually challenges existing customers’ habits (cultural barriers), companies’ organisations (corporate barriers), and regulative framework (regulative barriers). Starting from these considerations this chapter first investigates the barriers that affect the attractiveness and acceptance of eco-efficient PSS alternatives. A debate is then opened on the aesthetics of eco-efficient PSSs and the way in which aesthetics could enhance specific inner qualities of eco-efficient PSSs, i.e. facilitating and enhancing their wider diffusion. Through the analysis of several case studies, and integrating insights from semiotics, the chapter then outlines several research hypotheses on how the aesthetic elements of an eco-efficient PSS could facilitate user attraction, acceptance and satisfaction

Product Service Systems and Sustainability: Opportunities for Sustainable Solutions

Given that the concept of PSS is beginning to 'catch on' and gain attention, it is time for UNEP to contribute to, and influence the progress of PSS, to ensure that in concept and application it incorporates the idea of sustainability. In this context its potential is not generally understood by the public and private sectors or civil society. This booklet is intended to contribute to the dissemination and the discussion of the PSS concept as a promising approach to sustainability. The ultimate goal must be to achieve Sustainable Product-Service Systems. This UNEP publication is targeted at industry and government, academia and civil society to explain PSS – their potential benefits and limitations – in the sustainability context – using real company examples. To prepare this booklet, UNEP has drawn on the knowledge and experience of PSS experts to flesh out the concept of a sustainable PSS, to collect case studies of PSS in practice, to begin to document both its benefits and the hurdles which need to be overcome in its application, and to suggest ways forward in its development

Copyright @ 2012 Greenleaf PublishingEco-efficient Product-Service System (PSS) innovations represent a promising approach to sustainability. However the application of this concept is still very limited because its implementation and diffusion is hindered by several barriers (cultural, corporate and regulative ones). The paper investigates the barriers that affect the attractiveness and acceptation of eco-efficient PSS alternatives, and opens the debate on the aesthetic of eco-efficient PSS, and the way in which aesthetic could enhance some specific inner qualities of this kinds of innovations. Integrating insights from semiotics, the paper outlines some first research hypothesis on how the aesthetic elements of an eco-efficient PSS could facilitate user attraction, acceptation and satisfaction
