Abstract
Purpose
To design for additive manufacturing (AM), the decision to use AM needs to be taken early in the product development process. Therefore, engineers need to be able to estimate AM part cost based on the few parameters available at this point in the process. This paper aims to develop suitable cost estimation models for this purpose, focusing on buy scenarios, as many companies choose to buy parts at service providers.
Design/methodology/approach
This study applies analogical cost estimation techniques to a data set of price quotations for laser sintering and laser melting parts.
Findings
The paper proposes easy-to-apply cost estimation models for laser sintering and laser melting for buy scenarios. Further, it generates new insights on the AM service provider market.
Research limitations/implications
The proposed models are only suitable for buy scenarios and are only a snapshot of cost achievable in 2014.
Practical implications
The proposed cost estimation models enable engineers to approximate AM part costs early in the product development process and thereby ease the decision to rapid manufacture certain parts.
Originality/value
This study addresses two gaps in the AM cost literature. It is the first study to take a qualitative approach to AM cost estimation, which is more suitable early in the product development process than the currently available quantitative studies. Further, it develops the first cost estimation for buy scenarios.

Abstract
Purpose
The SARS-CoV-2 pandemic has had severe effects on economies worldwide and, in particular, on public institutions that must keep their operations running while supply chains are interrupted. The purpose of this study is to examine how public institutions act during a pandemic to ensure the security of supply.
Design/methodology/approach
The distinct focus is if, why and how public institutions have adopted additive manufacturing (AM) – a production technology colloquially known as three-dimensional printing in which a product is created by joining raw material layer by layer based on a digital model (computer-aided design [CAD] file) of the product – in reaction to supply disruptions caused by the SARS-CoV-2 pandemic. For this purpose, four cases within the context of the pandemic supply disruption are used as the units of analysis.
Findings
The findings are twofold: public institutions reacted, on the one hand, with a behavioral solution approach, trying to solve the supply disruption with new or changed forms of cooperation and collaboration. On the other hand, public institutions used a technical solution approach (TSA) as a supply disruption response and intensified their use of AM.
Research limitations/implications
This research derives an implications model that focuses on the TSA. Considering the ex ante and ex post phases of the disruption, several effects of AM on resilience are identified. The most relevant is the long-term learning effect (i.e. AM data created during this disruption might also help in a new disruption).
Practical implications
Practitioners who act under extreme pressure and uncertainty are informed by cases that have managed to close bottleneck situations with either a behavioral or TSA. Specific strategies are given for how public buyers could use AM within a pandemic situation to mitigate supply bottlenecks, such as increasing their robustness by localizing sourcing and increasing agility by combining traditional and additive supply sources. Additionally, insights are provided into how public organizations can increase their level of preparedness by including disruption paragraphs, establishing CAD databases, in contract clauses and keeping reserve contracts with AM service providers.
Originality/value
This research contrasts behavioral and technical solution concepts for a pandemic in the public sector. Thus, it provides insights into the relative benefits of AM and causes and effect with regard to how AM affects supply robustness and agility.

Abstract
This study examines a way to enhance the effectiveness of commercials embedded in the telecasts of mega sporting events. We hypothesise that embedded commercials are more likeable when the cues of the commercials match the motivations induced by the telecasts of sports games. Specifically, we posit that the telecasts of mega-sporting events induce motives of relatedness (rather than motives of competence) and that the advertisements embedded in these telecasts will be more effective when they appeal to the relatedness motive. The results support this hypothesis. Theoretical and practical implications are discussed and future research directions are provided.

Abstract
Purpose
The healthcare ecosystem continues to evolve with new technological developments with the support of its stakeholders. The technology-driven and patient-centric Healthcare 5.0 (H5.0) ecosystem is undergoing a transformation promising enormous benefits. However, the need to identify and understand the inherent challenges and barriers faced in the journey of H5.0 implementation and the relevant countermeasures for accelerated implementation has become critical.
Design/methodology/approach
The current research paper has utilised the Delphi approach for the collection of information and applied a well-proven quality function deployment (QFD) methodology for analysis.
Findings
The house of quality (HOQ) tool from the QFD has highlighted the critical H5.0 challenges which contribute to, approximately, 60% of the total weight. The identified top five process descriptors from the developed HOQ also contribute, approximately 60% among overall countermeasures. A useful H5.0 implementation progress (HIP) index has been recommended for tracking the progress made in the H5.0 implementation journey.
Originality/value
This research is among the first that has provided the application of the HOQ approach in the QFD methodology in the domain of H5.0. It has provided useful insights to the stakeholders. Furthermore, the development of a simple and practical HIP index is another useful value addition.
