To stay competitive in today’s environment, characterized by changing customer requirements, digitalization, new technologies, etc., companies must deliver fast and continuous innovation. Manufacturing companies have therefore started to launch large-scale agile transformation initiatives. A specificity of manufacturing companies is their need for deeply specialized organizational units. Knowledge boundaries resulting from knowledge specialization tend to impact transformation initiatives. Therefore, this work examines the implications of knowledge boundaries between organizational units for a large-scale agile transformation initiative of a manufacturing company. The findings show that these knowledge boundaries imply a need for knowledge integration based on flexibility and dynamism as key aspects. A conceptual model that illustrates these aspects during the initial phase of implementation of these transformation initiatives is presented.

The manual execution of failure mode and effects analysis (FMEA) is time-consuming and error-prone. This article presents an approach in which large language models (LLMs) are integrated into FMEA. LLMs improve and accelerate FMEA with human in the loop. The discussion looks at software tools for FMEA and emphasizes that the tools must be tailored to the needs of the company. Our framework combines data collection, pre-processing and reliability assessment to automate FMEA. A case study validates this framework and demonstrates its efficiency and accuracy compared to manual FMEA.

The agile methodology is gaining attention among practitioners and researchers in hardware development. As a new methodology, it is a source of misunderstandings and misinterpretations. This is problematic at the managers' levels as they may hinder its adoption or lead to its impractical implementation and use. This study, therefore, aims to explore the manager's level of understanding of the agile methodology. The study identifies the similarities and differences between the fundamental elements of the agile methodology and the elements mentioned by managers in hardware development. The fundamental elements of the agile methodology are identified based on the elements presented in the Scrum method; the elements mentioned by managers are identified based on ten semi-structured interviews with managers in hardware development. The study shows that the understanding of the agile methodology varies largely among managers. The obtained detailed insights in the managers' level of understanding of the agile methodology could be used to develop appropriate support to facilitate its adoption and implementation.

Due to the current fast-paced business environment, new approaches to product development (PD) have been requested. In that matter, the agile approach has gained interest among researchers and practitioners. Based on its positive results in the software industry, it has started to be adopted in the manufacturing industry. Nevertheless, there are factors that manufacturing companies must consider while adopting the agile approach, and there is a lack of in-depth empirical studies about those factors. In that matter, this paper presents the preliminary findings of a single case study of a large manufacturing company. The data collection consisted of fifteen semi-structured interviews with persons with key roles in different organizational functions. The identified factors were analyzed and presented according to a product development system (PDS) perspective which encompasses people, process, and technology and tools subsystems. For the people subsystem, the study identified factors related to cross-functional integration and coordination, cross-functional communication, organizational culture, understanding of the agile approach, definition of roles and responsibilities, and people involvement and support. In respect of the process subsystem, the study identified factors associated with workload leveling and development interfaces. Regarding the technology and tools subsystem, the study identified factors related to the integration of information systems, and technology and manufacturing readiness levels. As a result, the study contributes further to the establishment of the factors that may influence the adoption of the agile approach in the PDS of a large manufacturing company.

All Additive manufacturing (AM) technologies require post-processing to produce parts that are ready for use. This post-processing can range from support material removal, to surface quality improvement, to colouring and painting, and to aging for polymer parts and heat-treatment for metal parts. Throughout the AM industry there is a vast amount of tacit knowledge in the area of post-processing but there, currently, exists very little documentation on the various post-processing methods for different AM technologies and materials. This leads to time being wasted by companies having to individually learn and develop post-processing methods. This chapter aims to correct this.

Material extrusion (a.k.a. fused deposition modelling or FDM) is an AM process in which material is selectively dispensed through a nozzle much like a hot-glue gun. Materials used are typically thermoplastic polymers and the part being constructed normally requires support structures for overhanging features. Some system use support material built from the same material as the print material, some use a different second material that is slightly easier to remove by mechanical force, and some use a second material that is soluble.

Metal powder bed fusion (e.g., direct metal laser sintering, selective laser melting, and electron beam melting) is an AM process in which thermal energy selectively fuses regions of a powder bed. Materials used include stainless steel, tool steel, aluminium, titanium alloys, nickel-based alloys, cobalt chrome, and precious metals such as gold. The part being constructed normally requires supports (sometimes called anchors) to be added, built from the same material as the part. These supports are removed manually after the build process, so the designer must allow room for access to the supports. Also, care must be taken when creating small features that are attached to the supports because they can break off accidentally during support removal.

This chapter describes the main additive manufacturing technologies in use today. Note, however, that new technologies are continuously appearing on the market, so this space is in a continuous state of flux. Some of the technologies also have minor variants such as, for example, a material extrusion which might have one, two, or even more, extrusion nozzles. The intent of this chapter is not to cover every single technology in existence but, rather, to give the novice an overall understanding how each category of AM technology works.

... For instance, similar hybrid methodologies have been successfully employed in industrial contexts, as seen in [31], where AutoML techniques improved the precision of FMEA predictions by addressing key industrial inefficiencies. Likewise, the integration of advanced language models into FMEA frameworks, as demonstrated by [32], highlights the potential for enhancing predictive modeling in complex administrative or industrial scenarios. The ability to simulate the impact of corrective actions on RPNs prior to their implementation is particularly valuable, as it supports data-driven decision-making and fosters a proactive risk management culture. ...

... Furthermore there is an insufficient understanding of the underlying mechanisms (Michalides et al. 2022). Moreover, the authors highlight that inadequate comprehension results in practices being executed devoid of a clear purpose (Orejuela et al. 2023). The fundamental configuration of the Scrum framework, established as a quasi-standard, comprises distinct elements that will be subject to in-depth analysis throughout this paper. ...

MANAGERS' UNDERSTANDING OF AGILE IN HARDWARE DEVELOPMENT

Proceedings of the Design Society

... Understanding the root causes of these defects and implementing effective remediation strategies are essential for enhancing the overall quality of BJ-printed parts. The demand for top-quality parts by the consumer market and the growing use of AM processes to create these parts have led to a greater need for quality control in AM [28][29][30][31]. Satisfying this demand requires a process by which final part quality can be predicted, given knowledge of the starting materials and the AM processes used. ...

... Thus, experimental validation and testing, is usually required . Design for Additive Manufacturing (DfAM) was introduced to bridge design with the realized properties of a part considering the specific process potentials and constraints in the manufacturing of additive manufacturing (AM) components (cf. Figure 1) (Diegel et al., 2019). This can be done by design guidelines (Lachmayer and Lippert, 2020;Diegel et al., 2019) or algorithms (e.g. ...

... Diegel, Nordin, and Motte (2019) created a practical guide for DfAM that provides considerations for designing a part with minimal print time, reduced post-processing requirements, and reduced anisotropy. However, the rules and principles listed by Becker, Grzesiak, and Henning (2005) and Diegel, Nordin, and Motte (2019) are quite general, focusing on aiding designers in considering the best utilisation of AM and its capabilities in their products. Diegel, Nordin, and Motte (2019) also stated that the number-one rule of DfAM is 'it depends', which means that design rules are variable and dependent on the geometry, part, materials, and AM technology. ...

... The weight cost of raw materials (e.g., powders, filaments, etc.) of AM is up to eight times more than the materials used in conventional methods (e.g., ingots, granulates, etc.). Use of the L-PBF is however justified, as the process facilitates part consolidation [78], lightweight products [20], and has an effective material utilization rate up to 99% [79]. The initial fixed cost of L-PBF system is earned back by a low amount of stand-by time and possibility to produce unique designs. ...

... From a mechanical standpoint, this is preferable, as the impact of this defect will incur a negligible effect, while the material relocation from the multistep method may induce premature buckling. Both methods, however, have observed non-symmetrical hollow cross-sections and both LBPF and SLA (that creates the template for the hollow-strut lattice) are restricted to specific span lengths for unsupported 0 • inclined struts [27]. Interesting, however, at a horizontal incline, LPBF may fabricate significantly larger unsupported overhangs (up to 4 mm) than SLA where 1 mm is recommended for acceptable manufacture. ...

... The true conformal cooling channels can be fabricated using Additive Manufacturing (AM) technology due to its ability to produce a highly complex part with reasonable production time and cost (Ford & Despeisse, 2016). A significant reduction of the cooling time is observed with the recent designs of conformal cooling channels with the novel topological designs including spiral (Wang et al., 2015), parallel (Diegel et al., 2019), zig-zag (Park & Pham, 2009), Voronoi , porous (Au & Yu, 2011), baffles (Park & Dang, 2010), and conformal porous structures (Tang et al., 2019). ...
