The paper attempts to address the following research questions (RQs): RQ1: What are the main research topics within PSS research? RQ2: What are future trends for PSS research?

Twenty years of research (1999–2018) on product-service systems (PSS) produced a significant amount of scientific literature on the topic. As the PSS field is relatively new and fragmented across different disciplines, a review of the prior and relevant literature is important in order to provide the necessary framework for understanding current developments and future perspectives. This paper aims to review and organize research contributions regarding PSS. A machine-learning algorithm, namely Latent Dirichlet Allocation, has been applied to the whole literature corpus on PSS in order to understand its structure.

The adopted approach resulted in the definition of eight distinct and representative topics able to deal adequately with the multidisciplinarity of the PSS. Furthermore, a systematic review of the literature is proposed to summarize the state-of-the-art and limitations in the identified PSS research topics. Based on this critical analysis, major gaps and future research challenges are presented and discussed.

On the basis of the results of the topic landscape, the paper presents some potential research opportunities on PSSs. In particular, challenges, transversal to the eight research topics and related to recent technology trends and digital transformation, have been discussed.

The purpose of this study is to investigate how manufacturers make collaborative decisions in the ecosystem in the context of digital servitization.

Constructing an inframarginal analysis mathematical model to transform the ideal ecological niche choice of firms into solving the problem of maximizing the utility of firms, exploring the service boundary conditions of digital service business under the ideal ecological niche choice and focusing on the effects of niche factor, digital technology input and transaction efficiency on the boundary decision.

The boundaries of digital services business are in dynamic change, and changes are influenced by a combination of niche factor, digital technology input and transaction efficiency. Businesses focusing on a single niche and fully collaborative business delivery models are more in line with the trends under the digital service transformation.

Analyzing ecosystem participants’ cooperative decision-making on digital services from the perspective of ecological niche strategy selection. The study enriches the research on firm niche theory as well as service boundary decision theory in servitization transformation and provides theoretical guidance and management suggestions for firms to construct appropriate service boundaries to achieve synergistic and stable development of service ecosystems in the process of digital servitization transformation.

The purpose of this paper is to develop a coherent theory and strategy for the achievement of quality outcomes that is meaningful and relevant to people at all levels of society. These should help the quality professional engage with people at all levels of society in the development of a culture that appreciates quality, systems and excellence. The research draws on the work of the community quality councils movement in the USA and sought to build on this experience in a village in northwest Ireland.

Action research employing an ethnographic type approach to a four year immersion period in a small industrious community. Its inductive nature and naturalist mode of enquiry did not lend itself to either the generation or analysis of quantitative data. Nevertheless it yielded many rich complex pictures or patterns of qualitative information requiring long periods of reflection to decipher the sense and meaning in them.

The findings can be encapsulated in one sentence “To achieve quality outcomes we must practise excellence and maintain systems that are fit for purpose”. This requires a radical reworking of Deming’s system of profound knowledge (SoPK) to make it relevant to the human complex adaptive systems that permeate the twenty-first century. These operate as autonomous service providers in a rapidly changing environment.

The findings of this research have transferability to all sectors in society pursuing purposeful activity. It is relevant at individual, interest-group, industry, institution and community level. It should make the development of a “quality culture” more attainable at all levels.

Provides quality professionals with new terminology and imagery to engage with, analyse and help autonomous human activity systems in the twenty-first century. It moves Deming’s SoPK to a new level more suited to human systems.

By explaining quality, excellence and systems in easily understood and accepted terms the Grange Excellence Model allows every individual, interest-group, industry and institution share the same language and images as they pursue quality outcomes. This unified approach could transform communities and society in general.

The research generates a seismic shift in the appreciation of quality, excellence and systems making them relevant and meaningful to people at all levels of society. This provides quality professionals with a methodology, images and vocabulary that will facilitate productive engagement with purposeful systems at all levels of complexity.

Elevating the human experience (HX) through research collaborations is the purpose of this article. ServCollab facilitates and supports service research collaborations that seek to reduce human suffering and improve human well-being.

To catalyze this initiative, the authors introduce ServCollab's three human rights goals (serve, enable and transform), standards of justice for serving humanity (distributive, procedural and interactional justice) and research approaches for serving humanity (service design and community action research).

ServCollab seeks to advance the service research field via large-scale service research projects that pursue theory building, research and action. Service inclusion is the first focus of ServCollab and is illustrated through two projects (transformative refugee services and virtual assistants in social care). This paper seeks to encourage collaboration in more large-scale service research projects that elevate the HX.

ServCollab seeks to raise the aspirations of service researchers, expand the skills of service research teams and build mutually collaborative service research approaches that transform human lives.

ServCollab is a unique organization within the burgeoning service research community. By collaborating with service researchers, with service research centers, with universities, with nonprofit agencies and with foundations, ServCollab will build research capacity to address large-scale human service system problems. ServCollab takes a broad perspective for serving humanity by focusing on the HX. Current business research focuses on the interactive roles of customer experience and employee experience. From the perspective of HX, such role labels are insufficient concepts for the full spectrum of human life.

The purpose of this paper is to examine a bold and ambitious scheme known as the North East transformation system (NETS). The principal aim of the NETS is the achievement of a step-change in the quality of health services delivered to people living in the North East region of England. The paper charts the origins of the NETS and its early journey before describing what happened to it when the UK coalition government published its proposals for unexpected major structural change in the NHS. This had a profound impact on the leadership and direction of the NETS and resulted in it taking a different direction from that intended.

The research design took the form of a mixed methods, longitudinal 3.5-year study aimed at exploring transformational change in terms of content, context, process and outcomes. The sample of study sites comprised 14 NHS trusts in the North East region chosen to provide geographical coverage of the area and to reflect the scale, scope and variety of the bodies that formed part of the NETS programme. The qualitative component of the research, which the paper draws upon, included 68 semi-structured interviews, observational studies and focus groups. Data analysis made use of both deductive and inductive frameworks. The deductive framework adopted was Pettigrew et al.’s “receptive contexts for change” and four of the eight factors stood out as especially important and form the basis of the paper.

The fate of the NETS was shaped and influenced by the eight factors comprising the Pettigrew et al. receptive contexts for change framework but four factors in particular stood out as being especially significant: environmental pressure, quality and coherence of policy, key people leading change, supportive organisational culture. Perhaps the most significant lesson from the NETS is that achieving whole systems change is particularly vulnerable to the vicissitudes of politics especially where that system, like the UK NHS, is itself subject to those very same pressures. Yet, despite having an enormous influence on health policy, the political context is frequently avoided in research or not regarded as instrumental in determining the outcomes in respect of transformational change.

The chief limitation is the credibility and authenticity of the interviews captured at particular points in time. These formed the datebase for subsequent analysis. The authors sought to guard against possible bias by supplementing interviews with observational studies and focus groups as well as running two dissemination events at which emerging findings from the study were subjected to independent external scrutiny and comment. These events provided a form of validation for the key study findings.

The research findings demonstrate the importance of context for the likely outcome and success of complex transformational change initiatives. These require time to become embedded and demonstrate results especially when focused on changing culture and behaviour. But, in practice, allowing sufficient time during which the organisation may remain sufficiently stable to allow the change intervention to run its course and become embedded and sustainable is highly problematic. The consequence is that bold and ambitious efforts like the NETS are not given the space and stability to prove themselves. Too often, politics and external environmental pressures intrude in ways that may prove dysfunctional and negative.

Unless a different approach to transformational change and its leadership and management is adopted, then changing the NHS to enable it to appear more responsive to changing health care needs and expectations will remain a cause for concern. Ultimately the public will be the losers if the NHS remains insensitive to changing needs and expectations. The patient experience was at the centre of the NETS programme.

The study is original insofar as no other has sought to evaluate the NETS independently and over a reasonable time period. The research design, based on a mixed-methods approach, is unusual in evaluations of this nature. The study’s conclusions are not so original but their value lies in largely confirming and reinforcing the findings from other studies. It perhaps goes further in stressing the impact of politics on health policy and the negative consequences of constant organisational change on attempts to achieve deep change in the way the NHS is organised and led.

The purpose of this article is to explore how the application of service design can support financial organisations to implement their customer-centric business strategy.

This explorative research leaned on a subjective philosophy of interpretivism and followed an explorative qualitative approach by applying in-depth interviews. An abductive mindset was used for theory development.

The paper introduces a model that explains how service design can be used to implement customer-centric business strategy in financial organisations. The model explains the link between the business strategy and service design and highlights five principles of service design – namely customer-centred, co-creative, holistic, contextual and systemic – which guide designers and business developers when applying service design. In addition, customer journey represents an essential method of service design when aiming for a superior customer experience.

The research implications of this study relate to novel knowledge of applying service design to implement a customer-centric strategy. The paper encourages managers of established financial organisations to use service design to implement their strategy for a superior customer experience. Our results recommend the customer journey as a main method of service design for this purpose and highlight the prospect of making customer journeys at various levels across organisations.

This paper contributes to literature by integrating knowledge about business strategy, customer centricity and service design in a novel way.

This paper highlights the potential of social activism – defined as a public act that aims to challenge the status quo by bringing alternative views or narratives to the debate – in transformative service research and proposes a future research agenda.

This paper builds upon a review of social activism in the management and communications literature to identify its potential for social change in service (eco)systems.

This paper outlines three ways in which social activism can influence companies (external activism, internal activism, and activism as practice) and illustrates how they can be used to advance transformative service research in selected priority areas.

This paper develops a future research agenda and suggests research questions that could guide scholarly inquiry at the intersection of social activism and transformative service research.

For managers and policy makers, this paper highlights how social activism can influence companies' attempts to drive social change.

This paper is among the first to link social activism and transformative service research and highlight novel research opportunities at their intersection.

E-government development (EGD) is vital in enhancing the institutional quality and sustainable public service (SPS) delivery by eradicating corruption and cybersecurity crimes.

The present study applied econometric fixed-effect (FE) regression analysis and random forest (RF) algorithm through machine learning for comprehensive estimations in achieving SPS. This study gauges the nexus between the EGD as an independent variable and public service sustainability (PSS) as a proxy of public health services as a dependent variable in the presence of two moderators, corruption and cybersecurity indices from 47 Asian countries economies from 2015 to 2019.

The computational estimation and econometric findings show that EGD quality has improved with time in Asia and substantially promoted PSS. It further explores that exercising corruption control measures and introducing sound cybersecurity initiatives enhance PSS's quality and support the EDG effect much better.

The study concludes that E-Government has positively impacted PSS (healthcare) in Asia while controlling cybersecurity and institutional malfunctioning made an E-Government system healthier and SPS development in Asia.

This study added a novel contribution to existing E-Government and public services literature by comprehensively applied FE regression and RF algorithm analysis. Moreover, E-Government and cybersecurity improvement also has taken under consideration for PSS in Asian economies.

The purpose of this study is to identify, analyze and explain the ethical implications that can result from the datafication of service.

This study uses a midrange theorizing approach to integrate currently disconnected perspectives on technology-enabled service, data-driven business models, data ethics and business ethics to introduce a novel analytical framework centered on data-driven business models as the general metatheoretical unit of analysis. The authors then contextualize the framework using data-intensive insurance services.

The resulting midrange theory offers new insights into how using machine learning, AI and big data sets can lead to unethical implications. Centered around 13 ethical challenges, this work outlines how data-driven business models redefine the value network, alter the roles of individual actors as cocreators of value, lead to the emergence of new data-driven value propositions, as well as novel revenue and cost models.

Future research based on the framework can help guide practitioners to implement and use advanced analytics more effectively and ethically.

At a time when future technological developments related to AI, machine learning or other forms of advanced data analytics are unpredictable, this study instigates a critical and timely discourse within the service research community about the ethical implications that can arise from the datafication of service by introducing much-needed theory and terminology.

The purpose of the paper is to present a service design (SD)-based methodology developed to help small and medium enterprises (SMEs) undertake organisational change.

This research used the design science research methodology, which enabled the creation of the Service Design for Organisational Change (SD4OCh) methodology. A real case study of a small service company specialised in neuropsychological disorders was used for the definition and validation of SD4OCh.

The main outcome of this study is the SD4OCh methodology, which is based on three key stages: diagnosis (knowing where to begin by detecting the organisation's strengths and weaknesses), innovation (improving the structure/processes and designing/redesigning services by employing a customer-centric approach), and implementation (enabling the definition of the route towards organisational change). There is also a transversal evaluation stage, which quantifies the organisational changes.

This study adds valuable knowledge to the service science research field and contributes to the awareness of the usefulness of SD theory within companies, especially those which are small and medium-sized, since those companies lack the tools and methods required to tackle organisational change, signifying that the challenges the companies confront are different to those of larger companies.

Although this is a SD-based research, the SD4OCh methodology was developed in order to enable companies to make holistic changes, namely, to innovate their services, structure, and processes, thus supporting and guiding organisational change.
