- In an economic paradigm where companies think that more is better and resources are considered infinite, waste, pollution, and environmental degradation are often the result. This can, in turn, be addressed by companies focusing on offerings that are both effective and resource efficient. However, this type of offerings can be more uncertain and complex due to multiple factors such as multiple actors and conflicting objectives taking place at once. Dedicated design support for the relatively new offerings will be helpful for designers in industry. Large and small companies could benefit from the dedicated design support to successfully realize these types of offerings. However, the type of support they might need is not clear. Differences and similarities among large and small companies could guide researchers in providing more reliable support. Therefore, the aim of this research is to present differences and similarities of design support needs among large companies and small and medium enterprises. This is carried out through semi-structured interviews and follow-up meetings. The results show that differences include a formal product realization process for large companies and an informal or no process for smaller ones. Similarities point at design support for better communication and management of their offerings with regard to lead time as well as lifecycle and strategic thinking for decision making. The conclusions highlight the importance for researchers to provide design support that purposefully addresses specific needs.

- The ability for a product or a service to meet customer needs and requirements efficiently before its market launch is a key-point in design and development activities. Quality Function Deployment (QFD) represents one of the most powerful design methods to achieve such a goal.This study investigates the QFD-based methods proposed in the last two decades, whose use in different ambits of Design for X (DfX) is reported to be effective.We selected most common QFD based methods, analysing how designers can implement and coordinate them in design activities effectively throughout their application to an identical case study.

- Customizing offerings to match customers’ specific needs is a common practice for manufacturers striving to maintain their competence in markets. Despite Product/Service Systems (PSSs) having developed substantially in industry and academia for the last two decades, no scientific review of PSS customization has been published. This prompted us to conduct a review of scientific papers relating to products, services, and PSS customization with a focus on design, with the aim of clarifying future research directions in PSS customization. In particular, distinct design models and methods were individually examined, with a special focus on service aspects, in terms of what to design and how to design it. The population of papers included in the review was those included in the Web of Science. Even though service customization has been utilizing the knowledge generated by product customization, which has been researched extensively for decades, there are differences between them, such as the difficulty associated with modularity. The same or even larger differences apply to PSS customization, because, apart from service characteristics, PSS also has product characteristics and thus is more complex. Results also include that the module-based platform strategy used in service customization can also be used for PSS. Although several papers concerned with PSS customization have been published thus far, their focus has been on the service aspect of PSS, providing further research opportunities. Existing methods to design PSS can be also applied to develop a method for PSS customization.

A failure analysis method for designing highly reliable product-service systems
- 2018

- Recently, product-service systems (PSSs), which create value by integrating a physical product and a service, have been attracting attention. In PSSs, it is critical for a provider to offer highly reliable products and services. To do so, the provider needs to effectively and efficiently detect possible failures, and then, take adequate measures against them in the conceptual design stage. However, in current studies on product failure analysis, service aspects are not covered in analyzing failure causes and developingmeasures. On the other hand, product aspects are hardly considered in existing methods of service failure analysis. To fill the gap, this paper proposes a method for failureanalysis in PSS design called PSS failure mode and effect analysis (PSS FMEA). Especially, this paper extends theframework of FMEA, and then, a procedure for PSS FMEA is introduced so that designers can analyze failures and develop measures in consideration of both product andservice aspects. Furthermore, the proposed method supports designers in finding new business opportunities. The proposed method was applied to a real offering of products and services by a cleaning machine provider and found effective.

- Remanufacturing is a crucial component for our societies tomove toward a circular economy. Compared to newmanufacturing, the distinctive nature of remanufacturing isfound to have high variability, high uncertainty and, thereby,complexity. Therefore, remanufacturers need to enhance theirability to adjust their systems flexibly. Especially, the ability toreconfigure the production planning and control is crucial forreacting to the high variability and uncertainty. However, fewpractical methods to do that are available so far. Therefore, tosolve this problem, this paper aims to propose a method fordesigning processes of production planning and control inremanufacturing based on the concept of loosely coupledsystems. In the proposed method, Design Structure Matrix(DSM) is applied to identify loosely coupled subsystems thatenable to localize impacts of changes within themselves. Thesesubsystems are also utilized to appropriately determine leveragepoints, as well as allocate human resource. Through theapplication to a real case of remanufacturing, the proposedmethod was found to be effective for reconfiguring teams andprocesses for production planning and control depending ongiven uncertainties, as well as performing production planningand control activities efficiently.

- Recently, a circular economy has attracted global attention as an approach for addressing material security and resource-efficiency issues. As our societies shift toward a circular economy, manufacturers need to not only produce environmentally conscious products but to also realize reliable systems that will ensure the closure of the loops of the products, components, and materials. To do so, early-stage design is crucial to effectively and efficiently detect possible failures and then take adequate countermeasures against them. Although a few methods of failure analysis have been proposed to address environmental issues, these methods have failed to consider the cause–effect relationships among failures. This will hinder manufacturers from identifying core problems that should be addressed in a given system. Therefore, this study extends failure mode and effect analysis, which is an engineering technique used to address potential failures, by addressing the entire system reliability in relation to circularity. As a result of a case study of a manufacturer aiming to increase circularity with their products on the market, we revealed that the proposed method is useful in the early stage of design to (a) identify failure modes where effects are largely given to or received from other failures, (b) develop countermeasures effectively by addressing root causes of failures, and (c) find an opportunity to collaborate with external actors.

- In manufacturing, systems combining physical products and services have been attracting much attention. For such systems, designers need to focus on customer requirements rather than on the achievement of functionality. Methods are proposed in this paper for the analysis of requirements and extension of the design process proposed in Service Engineering. The focus is on the specification of service users in a client organization and on the extraction of their requirements in consideration of the organizational objectives of the client. The effectiveness of the method is demonstrated by an application, where a bank is a target client of a service.
