Evolutionary design framework for Smart PSS: Service engineering approach
Introduction
Digital technology is transforming industry, economy, and society on a global scale. It is commonly acknowledged that data collected with digital technologies is a new resource that can promote innovations in various industries [1]. Advanced sensors attached to products and environments, known as the Internet of Things (IoT) are able to collect huge amounts of data about our life and work. The analysis of these data, for example, by using statistical methods and rapidly evolving machine learning techniques, is changing business processes in an efficient and effective way.
Digitalization promotes servitization [2], [3]. A Product-Service System (PSS) as an integrated product and service offering that delivers value in use to the customer [4], is naturally influenced by digitalization. Recently, new types of PSS which are supported or enhanced by digital technologies attract strong attentions. One of the representative concepts is Smart PSS [5]. The Smart PSS concept covers a wide variety of value propositions in different industries and life and work settings, while the traditional PSS concept mainly focuses on product-based industrial offerings [4], [9]. The Smart PSS concept is expected to create greater value with the full use of digital technologies. However, available data from digital technologies is actually limited by technical, financial, and social reasons. Smart PSS needs to be designed by considering and even overcoming this limitation. In addition, the context for applying Smart PSS dynamically changes, which makes a designed Smart PSS outdated rapidly. These aspects have not been sufficiently examined in the previous studies.
In this study, we propose an evolutionary design framework for Smart PSS to overcome these challenges. Our approach is based on the service engineering research, which has been contributing to the design and development of PSS. We examine how the proposed framework works for designing a Smart PSS, with a case study about the digitalization of a restaurant business.
This paper consists of the following sections. In Section 2, we explore related studies on Smart PSS and its design, specifically focusing on PSS and service engineering studies. Then, we illustrate two research challenges in Smart PSS design. In Section 3, we propose an evolutionary design framework that consists of three conceptual spaces and three cycles. Section 4 shows an illustrative case study for the proposed framework. After a discussion of the case study in Section 5, we provide concluding remarks in Section 6.

PSS and Smart PSS
The term Product-Service System (PSS) was coined in the late 1990s. Goedkoop et al. [7] defined PSS as “a system of products, services, networks of ‘players’ and supporting infrastructure that continuously strives to be competitive, satisfy customer needs and have a lower environmental impact than traditional business models.” As is seen in this definition, the original focus of PSS lies in environmental sustainability. Thus, life cycle analysis has been an important topic in PSS design [8].
Evolutionary design framework for Smart PSS
Based on the limitations of existing studies on Smart PSS design, we suggest an evolutionary design framework for Smart PSS, shown in Fig. 2.
In this framework, Smart PSS consists of three space concepts, including real space, cyber space and knowledge space. Specifically, knowledge space aims to fill the research gap about unobservable states of real space. In addition, this framework contains three cycles, including data cycle, in-system design cycle and ex-system design cycle, to drive and
Case study
We examine the proposed framework with an illustrative case study. This case is a series of research projects toward digitalization of service work at a Japanese cuisine restaurant company. This restaurant company has been keen on digitizing their service operations and has adopted various digital technologies such as an information sharing system of customer information and requests [59] and a demand forecasting method based on Point-Of-Sales (POS) data [60].
This case study covers four
Effectiveness for designing Smart PSS
We first discuss the effectiveness of the proposed framework toward the challenges in designing Smart PSS. Concerning the issue of unobservable states in real space, the first project showed the effectiveness of the proposed approach. The collected data were able to represent the trajectories of the waitstaff between the front and back offices, but it was difficult for the research members to tell why those trajectories appeared. The participants of the CSQCC session were able to interpret the
Conclusion
In this study, we explored the challenges in designing a Smart PSS from the theoretical perspective and developed a design framework to overcome these challenges. We first figured out the challenges in designing Smart PSS, caused by the theoretically and practically imperfect digital twin; these challenges are unobservable states and dynamic changes in real space. To respond to these challenges, we proposed an evolutionary design framework for Smart PSS based on the service engineering

UNISON framework of model-based innovation for collaborative innovation of smart product-service system design
2022, Computers and Industrial EngineeringCitation Excerpt :Several previous efforts have been made to advance the innovative design approaches for smart PSS. Among them, some traditional design methodologies were extended or modified to be applied in the smart PSS design, such as TRIZ (Chou, 2021; Lee et al., 2019), QFD (Wang, 2017), AD (Riel et al., 2018), FBS (Cao et al., 2021), and service engineering (Watanabe et al., 2020). Other studies developed the approaches by big data analytic techniques (Li et al., 2021; Wang et al., 2021; Zheng et al., 2018) or digital twin-enabled perspective (Wu et al., 2021) for the smart product or e-services design.
