The purpose of this paper is to gain insight into whether additive manufacturing (AM) represents incremental, radical, disruptive innovation or an industrial revolution and its implications.

This study applies a desk research strategy. Data were collected through a variety of industry sources as well as academic publications.

It was found that AM represents different innovations in different settings, while it represents incremental innovation in one industry, it has led to radical changes in other industries. There are also indications that it has a disruptive nature and some of the developments appear to be of the industrial revolutionary type, i.e. they cause fundamental shifts in society. Some explanation for the observed differences can come from different performance objectives.

The spread of AM has been limited due to initial intellectual property protection. That means that while illustrations and examples were found for the different types of innovations, the level in which AM will ultimately penetrate manufacturing industries and society overall is not (yet) known. This calls for continued research for instance to study, in-depth, the adoption characteristics of AM in very specific settings.

Manufacturing is undergoing many changes as a consequence of the AM innovation. Many manufacturing industries have already been impacted through incremental changes as well as radical changes to entire industry dynamics. Manufacturers are advised to carefully monitor the continuous innovations in the technological capabilities of AM and their competitive and strategic consequences for adoption decisions.

AM has an impact on many aspects of society because it affects many industries and enables household manufacturing. It has also affected education, i.e. the current generation of students in terms of skill requirements, and leads to legal difficulties in terms of intellectual property.

This study contributes to the understanding of the AM innovation and the widespread implications for different manufacturing industries and society at large.

The purpose of this paper is to explore what underlies the development of the consumer 3D printing industry and gain insight into future developments and its potentially disruptive impact on the existing manufacturing industry.

A combination of approaches was followed. Initially a consumer 3D printer was purchased to gain first-hand experience as part of a practical research case study. Results were discussed with manufacturers and additional information was sought, and triangulated, via a survey and an exploratory bibliometric study.

Many characteristics are in place to identify consumer 3D printing as a potential disruptive technology for the manufacturing industry. For example, the cost of consumer 3D printing is lower than for traditional manufacturing. However, the current adoption rate is low and the user friendliness and technological capabilities need to improve.

The main limitation is the exploratory nature of the study which does not allow generalizations.

If developments and adoption patterns continue, then traditional manufacturing industries, distribution channels and the transportation sector may become threatened.

Technological advances in consumer manufacturing can potentially threaten several economic sectors, which can lead to loss of jobs and affect budgets of states of countries that depend on sales tax.

One of the first studies to employ experiments in combination with other methods to gain insight into adoption patterns and the disruptive nature of consumer 3D printers specifically, rather than industrial 3D printers or new business models as a result of 3D printing technology.

Risk management has become an integral part in businesses around the world. In the construction industry, risk management has also been introduced and has been mainly entrusted in the hands of the project team to go through a laid down risk management processes to identify possible risk events, which may occur during the project execution and the impact they may have on the project deliverables should they occur. It is, however, believed that small construction firms do not take risk management as a serious exercise even though most of the project risks are transferred to them as subcontractors. The purpose of this study was, therefore, to investigate risk management processes in the small construction companies and the impact of risk management on their project deliverables.

A case study of a single construction company was used for this study. Data were collected through structured questionnaire to 16 respondents who are involved in the project execution in the case study company. Two managing directors of the case study company were also interviewed. In total, 11 project site meetings were also attended to observe meeting proceedings and to record issues discussed. In total, 15 monthly project reports and project close-out reports were also studied. In total, One hundred and five completed projects of which 58 per cent were renovation projects, 27 per cent were new projects and 15 per cent were civil/structural works were also examined. The data were then analysed using excel analytical tool and the content analysis method.

The findings indicate that small construction companies with respect to the case study company do not have a specific laid down risk management processes that project team are made to go through before and during the execution of their projects. There is, however, no conclusive evidence regarding the impact of risk management on project performance as a significant number of projects done were able to meet a successful project performance indicators even though risk management exercises were not done. Some of the identified risk events that caused project failures are payment delays, labour related issues, subcontractor/main contractor related issues, insufficient contingency reserves/plan, etc.

Only one construction company was used as a case study for this research and all sources of data were related to a single company. The results may, therefore, be not generalisable.

The research has discovered that projects outcome could have improved tremendously if proper risk management exercises were implemented before project execution as most of the causes of project failures could have been identified through the risk management processes. This study, hence, gives an insight as to why small construction firms like the case study company should take risk management seriously in their projects execution to improve on the performance of their projects.

The aim of this paper is to explore the benefit of forecasting emerging biomedical therapy technologies as well as the rate of diffusion of resultant biomedical products in the context of management of technology.

The research method is exploratory using a case study approach. Techniques such as bibliometric analysis and the Bass diffusion model are utilized to assess the growth rate and market penetration of pulsed electromagnetic field therapy (PEMF) as a technology.

The penetration and growth rate of user acceptance of the technology in a global context are simulated across a 15‐year period. The technology forecasting model is also used in a case study to simulate the penetration of a product using ten years' medical application data of a patented pulsed electromagnetic field for biomedical therapy application in the global context. Useful correlation between bibliometric data for PEMF and real data for the case study is illustrated.

The research is limited to the case of PEMF data presented. Further research may be done on other PEMF technology applications.

Aspects of a holistic management model that was developed for high technology companies are invoked in the practical realisation of the professional paradigm shift required when an emerging biomedical therapy technology is in the process of becoming mainstream.

It has been shown that technology diffusion traces exist for PEMF therapy technology as is evident from the bibliometric PEMF global data presented. Furthermore it is possible to simulate the PEMF therapy technology diffusion process with a Bass diffusion model incorporating innovation imitation and market size coefficients.

In this regard, this paper aims to wonder how willing to co-create sustainable practices customers of irresponsible Industry 4.0 (I4.0) companies are? With this purpose, the authors began introducing I4.0 and sustainability, showing their theoretical gaps.

I4.0 has recently spread with its technological developments and social, economic and political ambitions, facing challenges-related, for example, to the implementation of sustainable practices and the stakeholders’ participation.

Then the authors conduct a literature review following a sequential mix-method approach that begins with a bibliometric analysis and ends with a content study to propose a conceptual model for I4.0 and sustainability. Once the authors understood the theoretical gaps in the framework of the conceptual model, the authors conducted an empirical verification between clients of a Colombian company of the I4.0 belonging to the logistic sector, specifically of the deliveries, asking them about the labor issues that the company faces with delivery people and their willingness to co-create. The authors analyzed the collected data through a structural equation modeling model, where the authors found that customers’ willingness to co-create depends on intrinsic behaviors like “responsible behavior,” followed by extrinsic behaviors such as “helping.”

In fact, stakeholders may support companies, but customers must learn how to assume a critical posture during their purchase decision.

Assessing project criticality in a project portfolio (PP) is of great practical significance to improve robustness from damage. While project criticality assessment has increased diversity in approaches, the understanding of vulnerable project impacts is still limited. To promote a better understanding of assessing project criticality, a vulnerability measurement model is constructed.

First, integrating the tasks, projects and corresponding relationships among them, a project portfolio network (PPN) is constructed. Second, the project's vulnerability is measured by combining the topological structure and functional attributes. Third, project criticality is assessed by the vulnerability measurement results. Lastly, the proposed model is applied in a numerical example to illustrate its suitability and effectiveness.

For academia, this study provides a novel perspective on project vulnerability measurement and expands project criticality assessment tools. For practitioners, the straightforward model provides an effective tool for assessing project criticality and contributes to enhancing project portfolio management (PPM).

The impact of the task on the project is considered in this study. Topological structure and functional attributes are also integrated for measuring project vulnerability due to the impact of random attacks in an uncertain environment, providing a new perspective on the requirements of project criticality assessment and the measurement of project vulnerability.

The present study has two objectives. First, one is to clarify the terms, “co-movement” and “co-integration” in the context of stock market indices. Second, to investigate empirically, whether an emerging stock market index represented by Nifty has moved together with DJI and N225 during the study period and whether they are co-integrated or not. This chapter tries to search out an answer for co-movement and co-integration staying within the theoretical framework through an extensive review of the literature. Moreover, the present study is unique because it tries to focus mostly on the pros and cons of financial integration and trade liberalization and the contributing factors responsible for trade and financial integrations leading to co-movement and co-integration among the countries considered in this study. India is taken as a proxy for an emerging economy. Furthermore, this chapter considers America and Japan as proxies for the developed countries around the globe and a significant country among the APAC nations, respectively. The empirical results reveal that not only three indices are highly correlated but they also possess a co-integrating relationship. This establishes the fact that neither is there any scope of international diversification in the short run nor in the long run. However, the Granger causality test results point out the fact that Nifty granger causes DJI and N225 during the study period.
