One of the critical reasons for the nonacceptance of additive manufacturing (AM) processes is the lack of understanding and structured knowledge of design for additive manufacturing (DfAM). This paper aims to assist designers to select the appropriate AM technology for product development or redesign. Using the suggestion provided by the design assist tool, the user’s design alterations depend on their ability to interpret the suggestion into the design without affecting the design’s primary objective.

This research reports the development of a tool that evaluates the efficacy values for all seven major standard AM processes by considering design parameters, benchmark standards within the processes and their material efficacies. In this research, the tool provides analytical and visual approaches to suggestion and assistance. Seventeen design parameters and seven benchmarking standards are used to evaluate the proposed product and design quality value. The full factorial design approach has been used to evaluate the DfAM aspects, design quality and design complexity.

The outcome is evaluated by the product and design quality value, material suit and material-product-design (MPD) value proposed in this work for a comparative assessment of the AM processes for a design. The higher the MPD value, the better the process. The visual aspect of the evaluation uses spider diagrams, which are evaluated analytically to confirm the results’ appropriateness with the proposed methodology.

The data used in the database is assumed to make the study comprehensive. The output aims to help opt for the best process out of the seven AM techniques for better and optimized manufacturing. This, as per the authors’ knowledge, is not available yet.

This paper outlines how Design for Lean Six Sigma methods aided a medical device manufacturing company in developing a new strategic space management and approval process for its manufacturing site.

The project demonstrates the application of the Design for Lean Six Sigma and structured Define, Measure, Analyse, Design, and Verify methodology in designing and implementing a process that enables the case study manufacturing site to improve its space utilisation and free up space.

The project was validated in one manufacturing department, and the Design for Lean Six Sigma methodology resulted in creating 15% new space for that area, with opportunities identified to free up 44.7% of the total manufacturing floor space and realise over €2.2 million cost savings as well as start to manufacture new products launched.

The manuscript highlights for the first time how the Design for Lean Six Sigma methodology can be utilised for space utilisation and can be leveraged by other manufacturers. The current study's limitations are that it is a single-site case study application. Future longitudinal case studies on Design for Lean Six Sigma application in more manufacturing space utilisation projects would be useful. This study has implications for identifying best practices for Design for Lean Six Sigma methodology application in the device industry, thus improving the state of the art for introducing new manufacturing lines.

This is the first published work to utilise Design for Lean Six Sigma methodology for space utilisation in a medical device company. This review will provide medical devices and other manufacturing organisations with recommendations on utilising Design for Lean Six Sigma and design for improved space utilisation to reduce costs.

The aim of this article is to map the use of AI in the user experience (UX) design process. Disrupting the UX process by introducing novel digital tools such as artificial intelligence (AI) has the potential to improve efficiency and accuracy, while creating more innovative and creative solutions. Thus, understanding how AI can be leveraged for UX has important research and practical implications.

This article builds on a systematic literature review approach and aims to understand how AI is used in UX design today, as well as uncover some prominent themes for future research. Through a process of selection and filtering, 46 research articles are analysed, with findings synthesized based on a user-centred design and development process.

The authors’ analysis shows how AI is leveraged in the UX design process at different key areas. Namely, these include understanding the context of use, uncovering user requirements, aiding solution design, and evaluating design, and for assisting development of solutions. The authors also highlight the ways in which AI is changing the UX design process through illustrative examples.

While there is increased interest in the use of AI in organizations, there is still limited work on how AI can be introduced into processes that depend heavily on human creativity and input. Thus, the authors show the ways in which AI can enhance such activities and assume tasks that have been typically performed by humans.

Civil engineering projects around the world have been underperforming for a long time. While the complexity of these projects will continue to increase, there is an urgent need to perform better. Although the integrated design process is critical for project success, the literature lacks studies describing the link to project performance. Therefore, this study aims to investigate the dominant variables that affect the integrated design process and consequently project performance.

A multiple case study was conducted to determine the dominant variables that affect the integrated design process and project performance. The research included four projects. Semi-structured interviews were the main source of data.

The cases indicated that the extent to which an integrated approach is achieved in the design process is essential for project performance. This applies to the integration of stakeholders’ interests as well as the integration of disciplines. Above all, it was concluded that the project team participants’ competencies for integration are a dominant factor for project performance, as the integrated design process has changed from a technical challenge to an integrative one.

This study provides insights into the dominant variable of the integrated design process that affects project performance, which is underexposed in the literature. The study results reveal the importance of competencies related to integration and adoption of the design problem context, which are not yet included in civil engineering design methods. In this respect, empathy is introduced as a new and critical competence for the civil engineering industry, which needs further research.

The purpose of this paper is to develop a framework to facilitate early supplier involvement (ESI) as an approach for reducing construction waste (CW) generated during the design process.

A research methodology consists of literature review, case studies and survey questionnaire was designed to achieve the abovementioned aim. First, the literature review was used to investigate CW, CW generated during the design process, the design process and ESI. Second, two construction projects were analysed to investigate the role of ESI towards reducing CW generated during the design waste. Third, a survey questionnaire was carried out with a representative sample of architectural design firms (ADFs) in Egypt to examine their perception and application of ESI towards reducing CW generated during the design process. Based on the results of the above, the research developed a framework to facilitate ESI during the design process to reduce CW.

Through literature review, the research highlighted the causes of CW generated during the design process and identified the benefits and challenges that encounter ESI in ADFs. Results of data analysis showed that “last-minute changes due to client requirements” was ranked the highest challenges of ESI in ADFs in Egypt followed by “lack of design experience”. Moreover, “providing technical information about materials and equipment and their capabilities” was ranked by respondents as the highest contributions of suppliers during the design process which leads to waste reduction followed by “better estimation of materials and costs”. Finally, respondents stated that “resistance of ADFs to include suppliers in the design phase” was ranked the highest challenge of ESI in the design process followed by “no clear guidelines or policies that organise ESI”.

Because of the conceptual nature of the proposed framework, it has to be tested and validated to ensure its capability to overcome the challenges of ESI as an approach for reducing CW generated during the design process.

This research presents a practical solution to the problem of CW generated during the design process through ESI.

The research discussed the causes of CW originated from the design process and the benefits and challenges of ESI in ADFs. It investigated the perception and application of ESI in ADFs in Egypt. The proposed framework which was designed to facilitate the integration of suppliers in the early stages of the project life cycle represents a synthesis that is novel and creative in thought and adds value to the knowledge in a manner that has not previously occurred.

This study aims to raise awareness of the key challenges, opportunities and priorities for evidence-based strategies’ application to inform building and urban design decisions.

This study uses deductive qualitative content and manifest analysis, using semi-structured interviews undertaken with building and urban design professionals who represent a UK-based organisation.

The challenges associated with the practical implementation of frameworks, potential application areas and perceived areas of concern have been identified. These not only include the need to practically test their use, but also to identify the most appropriate forums for their use. Participant responses indicate the need to further develop engagement strategies for their practical implementation, clearly communicating the benefits and efficiencies to all stakeholders.

Implications/ limitations of this study come with the fact that some of the respondents may possess inadequate professional experience in properly evaluating all the questions. Additionally, the information gathered is restricted to the UK geographical context, as well as coming from one organisation, because of data accessibility.

The findings of the study can be adopted by designers in the strategic definition level to overcome the key challenges associated with the use of evidence-based strategies, enhancing their decision-making processes.

As a theoretical contribution to knowledge, this study enhances the body of knowledge by identifying the challenges associated with the practical implementation of evidence-based strategies to inform building and urban design decisions. In practice, the findings aid urban planners, designers and academics in embedding and adopting strategies that enhance decision-making processes.

The aim of this paper is to develop a framework to enhance building maintainability through facilitating early suppliers’ involvement (ESI) in the design process.

A research methodology consisting of literature review, case studies and survey questionnaire was designed to achieve the above-mentioned aim. Firstly, literature review was used to examine the concepts of building maintenance, maintainability, the design process and ESI. Secondly, three case studies were presented and analysed to investigate the role of ESI towards enhancing building maintainability during the design process. Thirdly, a survey questionnaire was carried out with a representative sample of architectural design firms (ADFs) in Egypt to investigate their perception and application of ESI towards enhancing building maintainability during the design process. Finally, the research developed a framework to facilitate ESI in the design process in ADFs in Egypt.

Through literature review, the research highlighted the relationship between ESI and enhancing building maintainability and identified the roles, benefits, challenges and that encounter ESI in ADFs, factors for suppliers selection and levels of involvement. Results of the data analysis showed that “Difficulty of trusting external parties and sharing information with transparency” was ranked the highest challenge of ESI in ADFs in Egypt, followed by “Legal competitive advantage restrictions”. Moreover, “Better estimation for operation and maintenance costs” was ranked the highest contributions of ESI towards enhancing building maintainability, followed by “Reduce the number of operation and maintenance problems or reworks”. Finally, respondents stated that “Innovation, technical expertise, and competence” was ranked the highest supplier’s selection criteria, while “paying consultation fees for offering advice and recommendations to the design team” was ranked the highest form of supplier’s remuneration.

The proposed framework contributes to the body of knowledge through proposing five functions that aimed to facilitate ESI in the design process, a research area that received scant attention in construction research. In addition, because of the conceptual nature of the framework, it has to be validated to ensure its capability to overcome the challenges of ESI as an approach for enhancing building maintainability during the design process.

This research presents a practical solution that bridges the gap between theory and practice through overcoming the challenges that obstruct suppliers from being involved in the design process as an approach for enhancing building maintainability.

This research discussed the relationship between ESI and enhancing building maintainability as well as the roles, benefits and challenges that encounter ESI in ADFs. In addition, the research investigated the levels of suppliers’ involvement, selection criteria and forms of payment. Moreover, it investigated the perception and application of ESI in ADFs in Egypt towards improving building maintainability. The research proposed a framework to facilitate the integration of suppliers in the early stages of the project life cycle. It represents a synthesis that is novel and creative in thought and adds value to the knowledge in a manner that has not previously occurred.

Business process training is a crucial activity in the business process management lifecycle, performed whenever an organization needs to train workers about how to carry out their activities according to defined processes, after significant process changes, or whenever new workers come on board. Due to their motivational character, serious games have been understood as an unconventional alternative to support training in organizational processes. Still, methodologies to design serious digital games specifically for business process training are missing in the literature. This research paper presents a method – Play Your Process for Training (PYP4Training) – for designing digital games for business process training.

The research is guided by design science research methodologies and comprises the adaptation of Play Your Process (PYP), a method for designing business process-based digital games (BPBDG). PYP activities and supporting tools were shaped to cope with the specific requirements of BPBDG design for process training purposes, bringing to light a new method: PYP4Training.

PYP4Training was evaluated by designing a BPBDG for training a heavy equipment maintenance process in a multinational mining company. The game was evaluated by process owners and actors who reported a positive perception of the game as an option for process training. However, there is still space for improving trainees' engagement.

The research proposes an innovative way for business process training using digital games. Nevertheless, literature shows a lack of systematic procedures to build such games and results about their use.

The purpose of this paper is to review cases of artificial reefs built through additive manufacturing (AM) technologies and analyse their ecological goals, fabrication process, materials, structural design features and implementation location to determine predominant parameters, environmental impacts, advantages, and limitations.

The review analysed 16 cases of artificial reefs from both temperate and tropical regions. These were categorised based on the AM process used, the mortar material used (crucial for biological applications), the structural design features and the location of implementation. These parameters are assessed to determine how effectively the designs meet the stipulated ecological goals, how AM technologies demonstrate their potential in comparison to conventional methods and the preference locations of these implementations.

The overview revealed that the dominant artificial reef implementation occurs in the Mediterranean and Atlantic Seas, both accounting for 24%. The remaining cases were in the Australian Sea (20%), the South Asia Sea (12%), the Persian Gulf and the Pacific Ocean, both with 8%, and the Indian Sea with 4% of all the cases studied. It was concluded that fused filament fabrication, binder jetting and material extrusion represent the main AM processes used to build artificial reefs. Cementitious materials, ceramics, polymers and geopolymer formulations were used, incorporating aggregates from mineral residues, biological wastes and pozzolan materials, to reduce environmental impacts, promote the circular economy and be more beneficial for marine ecosystems. The evaluation ranking assessed how well their design and materials align with their ecological goals, demonstrating that five cases were ranked with high effectiveness, ten projects with moderate effectiveness and one case with low effectiveness.

AM represents an innovative method for marine restoration and management. It offers a rapid prototyping technique for design validation and enables the creation of highly complex shapes for habitat diversification while incorporating a diverse range of materials to benefit environmental and marine species’ habitats.

Designing digital artifacts is not a linear, straightforward process. This is particularly true when applying a user-centered design approach, or co-design, with users who are unable to participate in the design process. Although the reduced participation of a particular user group may harm the end result, the literature on solving this issue is sparse. In this article, proxy design is outlined as a method for involving a user group as proxy users to speak on behalf of a group that is difficult to reach. The article investigates the following research question: How can roleplaying be embedded in co-design to engage users as proxies on behalf of those who are unable to represent themselves?

The article presents a design ethnography spanning three years at a cancer rehabilitation clinic, where digital artifacts were designed to be used collaboratively by nurses and patients. The empirical data were analyzed using content analysis and consisted of 20 observation days at the clinic, six proxy design workshops, 21 telephone consultations between patients and nurses, and log data from the digital artifact.

The article shows that simulated consultations, with nurses roleplaying as proxies for patients ignited and initiated the design process and enabled an efficient in-depth understanding of patients. Moreover, the article reveals how proxy design as a method further expanded the design. The study findings illustrate: (1) proxy design as a method for initiating design, (2) proxy design as an embedded element in co-design and (3) six design guidelines that should be considered when engaging in proxy design.

The main contribution is the conceptualization of proxy design as a method that can ignite and initiate the co-design process when important users are unreachable, vulnerable or unable to represent themselves in the co-design process. More specifically, based on the empirical findings from a design ethnography that involved nurses as proxy users speaking on behalf of patients, the article shows that roleplaying in proxy design is a fitting way of initiating the design process, outlining proxy design as an embedded element of co-design.
