Technological developments and new customer expectations of immediacy have driven businesses to adopt on-demand service models. The purpose of this paper is to study the characteristics of a range of on-demand services in order to better understand the meaning of “on-demand” and its implications for service management. This enables the on-demand service logic to be applied to other service contexts, where it may add value for customers.

The study starts with a focused literature review and continues with a multiple case study methodology, as the on-demand service concept is in the early stages of theory development. Seven cases were studied, based on a maximum variation sampling strategy.

The results show that on-demand services are characterized by three interrelated characteristics: being highly available, responsive and scalable. Analysis further reveals that on-demand services display differences within the conceptual boundaries of these characteristics, i.e. they vary in terms of their availability, responsiveness and scalability.

Drawing on these findings, the study contributes to the service literature by being the first to specifically conceptualize and define the on-demand services concept and reveal three key characteristics that clarify the distinctive nature of this service type. Accordingly, on-demand services are clearly differentiated from other services. Additionally, the paper discusses the variety within on-demand services and develops an on-demand service continuum that gives detailed insights into the conceptual variations within such services.

For many decades, it has been recognized that maintenance activities should be adapted to the specific usage of a system. For that reason, many advanced policies have been developed, such as condition-based and load-based maintenance policies. However, these policies require advanced monitoring techniques and rather detailed understanding of the failure behavior, which requires the support of an OEM or expert, prohibiting application by an operator in many cases. The present work proposes a maintenance policy that relieves the high (technical) demands set by these existing policies and provides a more accurate specification of the required (dynamic) maintenance interval than traditional usage-based maintenance.

The methodology followed starts with a review and critical assessment of existing maintenance policies, which are classified according to six different aspects. Based on the need for a technically less demanding policy that appears from this comparison, a new policy is developed. The consecutive steps required for this functional usage profiles based maintenance policy are then critically discussed: usage profile definition, monitoring, profile severity quantification and the possible extension to the fleet level. After the description of the proposed policy, it is demonstrated in three case studies on real systems.

A maintenance policy based on a simple usage registration procedure appears to be feasible, which enables a significantly more efficient maintenance process than the traditional usage-based policies. This is demonstrated by the policy proposed here.

The proposed maintenance policy based on functional usage profiles offers the operators of fleets of systems the opportunity to increase the efficiency and effectiveness of their maintenance process, without the need for a high investment in advanced monitoring systems and in experts interpreting the results.

The original contribution of this work is the explicit definition of a new maintenance policy, which combines the benefits of considering the effects of usage or environment severity with a limited investment in monitoring technology.

This paper investigates the challenges encountered by manufacturing companies in managing sustainability in new product development (NPD). It describes six case studies of manufacturers aiming for sustainability improvements but experiencing difficulties in implementing them.

The paper starts with a literature study. Academic literature offers explanations as to why manufacturers want to implement sustainability in NPD, and suggests methods for such implementations. This paper employs the systems theory of control to build a research framework for analyzing the challenges. Empirical data are gathered through workshops and interviews with NPD managers in the case companies.

In-depth analyses have provided three insights. First, the study shows that sustainability pressures and incentives in a firm's contexts can be fuzzy or even absent. The fuzziness of sustainability incentives is often neglected in the literature on sustainability and NPD. Second, the case companies face difficulties when setting the scope, goals, and ambitions that effectively direct NPD decisions and efforts toward designing sustainable products. Third, the results show that deploying sustainability methods, tools, and metrics, such as a life-cycle assessment or design for environment (DfE), are not sufficient to achieve sustainability in NPD. These findings call for research on sustainability and NPD processes in contexts where sustainability incentives and needs are fuzzy so as to acquire insights applicable to sustainable product development management that is proactive rather than reactive.

Instead of focusing only on the output of sustainable products, this paper presents a more nuanced perspective on managing sustainability in NPD. Moreover, by adopting the holistic perspective of the systems theory of control, the authors challenge the assumption that there are already sufficient external incentives to force companies toward greater sustainability. Consequently, in the light of proactive sustainability management, the authors recommend three tracks for further research: organization and filtering of information concerning sustainability pressures and incentives in a firm's context; and how to manage sustainability proactively rather than reactively.

Success in manufacturing industries often depends on the ability of a firm to apply product platforms. In speeding up product development, platforms often enable companies to benefit from scale effects by reusing existing components in the development of new products. In the delivery of complex products and system (CoPS), however, platforms are frequently modified since components have to be changed within their life cycle to meet additional customer-specific engineering demands and evolving innovations in technology. In this article, it will be illustrated that intangible design elements can be used as platforms in firms that deliver CoPS. The paper aims to discuss these issues.

Through extensive fieldwork at a leading supplier of science-based lithography machinery, a modified platform concept was developed and tested that is labelled as the function-technology (FT) platform. The longitudinal data, collected on site, demonstrate positive effects of applying FT platforms.

The results show that an important explanation for firm's success in delivering lithography machinery with attractive performance is their ability to deliver variants that are specific in terms of physical modules, but common in terms of functions and technologies. Based on the results, it can be argued that establishing an FT platform will allow the efficient creation of variants within a family of CoPS.

The findings add considerable insight to the existing literature on operations management by explaining how intangible design elements, instigated during development, can be reused in the delivery of CoPS. Moreover, it enables development managers to more easily structure and reuse complex development tasks.

This paper addresses horizontal supply chain collaboration among autonomous freight carriers in the less-than-truckload industry. The main purpose of the paper is to identify and explain the challenges with joint operational decision-making in this context and investigate the precise role of information technology (IT) therein.

Empirical evidence is gathered by means of exploratory and explanatory case research, with multiple cases at the planning departments of European freight carriers operating in collaborative transportation networks.

Collaborating carriers face fundamental challenges in joint operational planning and control of collaborative transportation, despite the broad availability of state-of-the-art IT. These operational supply chain challenges can be explained by technological differences of the available IT applications, which hinder integration.

Any expectations with regard to state-of-the-art XML or EDI-based IT integration for improved joint operational decision-making in collaborative transportation networks should be considered with care. In particular, the authors' research findings may encourage practitioners to consider new planning and control procedures and develop dedicated IT applications for collaborating freight carriers.

The paper highlights the importance of horizontal supply chain collaboration for small and medium-sized freight carriers in the less-than-truckload industry and conceptualises how collaborative transportation networks are organised. Furthermore, an IT typology is introduced to explain the challenges with joint operational decision-making.

Many transportation companies struggle to effectively utilize the information provided by tracking technology for performing operational control. The research as presented in this paper aims to identify the problems underlying the inability to utilize tracking technology within this context. Moreover, this paper aims to contribute to solving these problems by proposing a set of design principles based on the concept of intelligent products.

The study as described in this paper adopts a design science research methodology consisting of three phases. First, a case study in a transportation company has been performed to identify the problems faced when utilizing tracking technology. Second, to overcome these problems, a set of design principles has been formulated. Finally, a prototype system based on the design principles has been developed and subjected to experimental and observational evaluation.

This paper identifies the problems associated with the utilization of tracking technology for the control of transport operations. Moreover, the proposed design principles support the development of information systems which overcome the identified problems and thereby enhance the utilization of tracking technology in a transportation context.

The commonly held perception that tracking technology will improve the ability to perform operational control does not unequivocally stand up to empirical scrutiny. While it is widely demonstrated that tracking technology is able to accurately capture the detailed operational information, it remains a fundamental challenge to transform this abundance of information into accurate and timely control decisions. This research provides a valuable contribution with respect to tackling this challenge, by identifying problems and providing solutions related to the utilization of readily available tracking technology.

In new product development (NPD), changes to the initial designs are often proposed for on‐going design projects due to new insights. These engineering changes belong to a wide range from incremental to radical and, in their impact, even to discontinuous change. Consequently, the actual workload of development projects confronted with engineering changes does not match the initial work estimates for the project's work packages. Accordingly, the intended timing of readiness of development projects in an NPD program will drift away. This timing is one of the causes of change propagation to other projects which results in even more engineering changes. For larger changes, the effects on timing may be disastrous. The purpose of this paper is to reveal the cause‐and‐effect relationships triggered by various types of changes and explain the need for a more integrated approach to managing engineering change.

A longitudinal case study was performed at a leading microlithography manufacturing company, in which almost 20,000 engineering changes were included. This study allowed the disclosure of the complexities of engineering change management and provides guidelines for handling the resulting problems arising from managing these various types of change.

In the study, various sources of complexities in managing engineering change were observed, which hinder effective implementation of various types of engineering change. Based on the case observations, a number of improvement possibilities are proposed, such as: alignment of goals and impacts of engineering change on all organizational levels; and planning, monitoring and controlling discontinuous engineering changes as separate projects.

Although further studies are needed to replicate the results, the paper gives a more thorough understanding of factors that could support the implementation of discontinuous innovation in incumbent firms by using the engineering change management process.

Global outsourcing shifts manufacturing jobs to emerging countries, which provides new opportunities for improving their economic development. The authors develop and test a theoretical model to predict first, how sustainable supply chain initiatives might influence reverse logistics outcomes and second, the impact of eco-reputation and eco-innovation orientation strategies on the deployment of sustainable supply chain initiatives. The paper aims to discuss these issues.

The proposed new model of antecedents and outcomes of sustainable supply chain initiatives underwent a rigorous empirical test through structural equation modeling with samples from an emerging market.

The results show that firms that implement sustainable supply chain initiatives can realize positive reverse logistics outcomes; the study also provides new insights into eco-innovation and eco-reputation strategic orientations as theoretically important antecedents of sustainable supply chain initiatives.

Though the authors identify three components of sustainable supply chain initiatives, other components could exist, and ongoing research should investigate them.

The findings have important implications for managers in emerging markets seeking to initiate ecologically friendly business practices. The authors offer strong evidence of the benefits obtained from reverse logistics in sustainable supply chain initiatives. Policy makers and firms attempting to nurture sustainable supply chain initiatives should not overlook the important role of eco-reputation and eco-innovation strategic orientations, which the results identify as important enablers.

This study offers evidence of the critical role of eco-reputation and eco-innovation strategic orientations in deploying sustainable supply chain initiative programs, as well as of their mutual effects. This study also offers empirical evidence that implementing sustainable supply chain initiatives leads to reverse logistics, creating value, and a new source of competitive advantages.

This purpose of this study is to provide an overview of the current state of research on Lean Six Sigma (LSS) and Industry 4.0 and the key aspects of the relationships between them. The research analyses LSS's evolution and discusses the future role of LSS 4.0 in an increasingly digitalized world. We present the benefits and motivations of integrating LSS and Industry 4.0 as well as the critical success factors and challenges within this emerging area of research.

A systematic literature review methodology was established to identify, select and evaluate published research.

There is a synergistic nature between LSS and Industry 4.0. Companies having a strong LSS culture can ease the transition to Industry 4.0 while Industry 4.0 technologies can provide superior performance for companies who are using LSS methodology.

One limitation of this research was that as this area is a nascent area, the researchers were limited in their literature review and research. A more comprehensive longitudinal study would yield more data. There is an opportunity for further study and analysis.

This study reviews the evolution of LSS and its integration with Industry 4.0. Organisations can use this study to understand the benefits and motivating factors for integrating LSS and Industry 4.0, the Critical Success Factors and challenges to such integration.

This is the first systematic literature review on LSS 4.0 and can provide insight for practitioners, organisations and future research directions.
