The capacity to guide the evolution and creation of new products (manufactured goods or services) is crucial for the enterprise's profitability. Hence, enterprises have acquired the capacity to manage the future of their product portfolio. However, companies that offer a combination of manufactured goods and services as an integrated system or a Product-Service System confront challenging conditions to maintain or increase their market share due to the complex relationship between manufacturing and service production systems. The complexity of a PSS makes it challenging to adapt its physical products to new customer requirements, satisfy new standards, or develop/adopt new technologies because any modification in one part of the system will undoubtedly affect the other. Therefore, it is necessary to propose an approach for managing the development process of a PSS from a broad perspective. The approach presented in this article combines the advantages of the Business Model Canvas to define the crucial functions of a business model with the service blueprinting capacity to represent service processes. The proposal describes a five stages methodology: Conceptualization, Business Model Design, Product-Service System (PSS) Scenarios, Blueprint design, and Validation. The methodology helps the analysis of a PSS from three perspectives: product, use, and result, which are the typical PSS scenarios. A case study applied to a company that distributes purified water is helpful to illustrate the methodology. Finally, the methodology includes some aspects that favor implementing creative and dynamic business models, emphasizing the constant changes in the evolution of products and services.

Although there exist various product and services to support people with dementia in their everyday activities and challenges, people with dementia and their informal caregivers experience many unmet needs. In this paper, we present the ongoing development process of a decision aid that aims to reveal these unmet needs and match them with relevant support and care solutions. This entails investigating the needs of people with dementia and caregivers, making an inventory of the product and service solutions, co-creating the question articulation to be used in the decision aid and developing and testing three design concepts. We aim that the insights we gained from the tests will inspire interaction designers and researchers that investigate person-centered dementia care.

The circular economy (CE) is heralded as reducing material use and emissions while providing more jobs and growth. We explored this narrative in a series of expert workshops, basing ourselves on theories, methods and findings from science fields such as global environmental input-output analysis, business modelling, industrial organisation, innovation sciences and transition studies. Our findings indicate that this dominant narrative suffers from at least three inconvenient truths. First, CE can lead to loss of GDP. Each doubling of product lifetimes will halve the related industrial production, while the required design changes may cost little. Second, the same mechanism can create losses of production jobs. This may not be compensated by extra maintenance, repair or refurbishing activities. Finally, ‘Product-as-a-Service’ business models supported by platform technologies are crucial for a CE transition. But by transforming consumers from owners to users, they lose independence and do not share in any value enhancement of assets (e.g., houses). As shown by Uber and AirBNB, platforms tend to concentrate power and value with providers, dramatically affecting the distribution of wealth. The real win-win potential of circularity is that the same societal welfare may be achieved with less production and fewer working hours, resulting in more leisure time. But it is perfectly possible that powerful platform providers capture most added value and channel that to their elite owners, at the expense of the purchasing power of ordinary people working fewer hours. Similar undesirable distributional effects may occur at the global scale: the service economies in the Global North may benefit from the additional repair and refurbishment activities, while economies in the Global South that are more oriented towards primary production will see these activities shrink. It is essential that CE research comes to grips with such effects. Furthermore, governance approaches mitigating unfair distribution of power and value are hence essential for a successful circularity transition.
