“…As mentioned before, applying Agile for physical products requires significant adaptation due to the restrictions inherent in hardware product development (e.g., lead times and costs of physical prototyping). As presented in Omidvarkarjan et al [26], AHD benefits from the application of adapted prototyping strategies such as feature separation, increased parallelization, and flexible switching of manufacturing processes. By doing so, time-consuming and costly hardware iterations can be accelerated, parallelized, or even prevented.…”

“…Besides transferring the principles of AHD, the training aims to provide participants with practices and techniques that allow them to apply the AHD approach to hardware products. Specifically, these techniques include prototyping strategies such as separate feature testing, parallel prototyping of subsystems, and switching of prototyping media to minimize lead time and cost [26].…”

“…This includes, for instance, the lead time and costs that are required to build physical prototypes. Numerous case studies showed that Agile methods and tools often need to be adapted to address the characteristics of physical products (e.g., [26]). As a result, firms in the mechanical engineering and manufacturing industry have only begun to rebuild their processes and organizational structure toward AHD in recent years [31].…”

Educational games are increasingly used to teach Agile development approaches to practitioners. Most of these training modules simplify the development environment, for example, by using LEGO bricks or playing cards. This oversimplification has been shown to result in limited transferability of learning to industrial practice. Furthermore, there is a lack of teaching modules that specifically address the challenges of applying Agile to physical products. In this paper, we present an open-source educational game that realistically simulates a hardware development project to teach Agile principles. Over 2 days, participants design, manufacture, and test modifications for a physical wire bending machine within an authentic engineering and production setting. The training mimics the typical roles, processes, and tools of industrial engineering teams to reflect the challenges of Agile hardware development. The module was evaluated with 44 industry professionals regarding perceived learning and user reaction. A combination of quantitative and qualitative methods was used for the experimental evaluation. The results showed a positive learning effect as the participants' average agreement with Agile principles increased through the training.Concerning user reaction, respondents reported a high degree of relevance, interaction, and confidence, indicating that the realistic simulation of the hardware development appropriately balanced the degree of realism with simplicity. The study showcases the opportunities of properly aligning game components to provoke learning situations targeted by the instructors. It contributes to the extant literature by providing a design framework (product, process, setting, and instruction) and open-source access to the tools used for implementation.

“…The main attraction of 3D printing technology is its high degree of flexibility (Kunovjanek & Wankmüller, 2020). As such, AM is suitable for prototyping, in which its benefits and practicality have been proven (Omidvarkarjan et al, 2020;Rainnie, 2020). AM can replace traditional machining to produce certain components.…”

The COVID-19 pandemic's impacts have been devastating for the global economy, particularly for manufacturing companies that have been forced to face challenges that were almost unheard of before. Many companies were completely unprepared for an event of this magnitude and tried to limit the damage by adopting specific countermeasures. Some of these were possible thanks to digital technologies and the digitization of business processes, which sometimes made it possible to reduce or eliminate negative effects. In particular, digital technologies have helped companies adapt during the crisis and ensure business continuity. This article aims to investigate how digital and Industry 4.0-enabling technologies have helped manufacturing companies cope with the pandemic's effects. The study indicates that some technologies have contributed more than others, although the Industry 4.0 paradigm's potential has not been exploited fully. This calls for future research directions to extend the scope of analysis in these aspects, particularly five specific areas: data and information management; (re)organization of work; de-globalization and reshoring; supply chain resilience; and environmental and social sustainability.

“…Second, only the final/current versions of the designs were included in our studies. Several of these "democratized" solutions have evolved over time, often through contributions from multiple designers from different parts of the world (Omidvarkarjan et al, 2020). Therefore, a direction for future research is to study the evolution of ideas over time in terms of their DfAM utilization and the subsequent effects on creativity and manufacturing efficiency.…”

Purpose The COVID-19 pandemic has resulted in numerous innovative engineering design solutions, several of which leverage the rapid prototyping and manufacturing capabilities of additive manufacturing. This paper aims to study a subset of these solutions for their utilization of design for AM (DfAM) techniques and investigate the effects of DfAM utilization on the creativity and manufacturing efficiency of these solutions. Design/methodology/approach This study compiled 26 COVID-19-related solutions designed for AM spanning three categories: (1) face shields (N = 6), (2) face masks (N = 12) and (3) hands-free door openers (N = 8). These solutions were assessed for (1) DfAM utilization, (2) manufacturing efficiency and (3) creativity. The relationships between these assessments were then computed using generalized linear models to investigate the influence of DfAM utilization on manufacturing efficiency and creativity. Findings It is observed that (1) unique and original designs scored lower in their AM suitability, (2) solutions with higher complexity scored higher on usefulness and overall creativity and (3) solutions with higher complexity had higher build cost, build time and material usage. These findings highlight the need to account for both opportunistic and restrictive DfAM when evaluating solutions designed for AM. Balancing the two DfAM perspectives can support the development of solutions that are creative and consume fewer build resources. Originality/value DfAM evaluation tools primarily focus on AM limitations to help designers avoid build failures. This paper proposes the need to assess designs for both, their opportunistic and restrictive DfAM utilization to appropriately assess the manufacturing efficiency of designs and to realize the creative potential of adopting AM.
