To improve understanding of prototyping practice at the fuzzy front end of the design process, this article presents an analysis of a prototyping dataset captured during the IDEA challenge – a 4-day virtually hosted hackathon – using Pro2booth, a web-based prototype capture tool. The dataset comprised 203 prototypes created by four independent teams working in university labs across Europe supported by interviews carried out with each of the teams after the event. The results of the study provide nine key findings about prototyping at hackathons. These include elucidation of the purposes of prototypes in physical, digital and sketch domains and characterisation of teams’ prototyping practices and strategies. The most successful strategy focused on learning about the problem or solution space, often via physical prototypes rather than following more prescriptive ‘theoretical’ methodologies. Recommendations on prototyping strategies in hackathons or similar scenarios are provided, highlighting the importance of practical strategies that prioritise learning and adaptation. The results of this study raise the broader question to the wider research community of how design research and teaching should balance high-level strategic approaches with more hands-on ‘operational’ prototyping.

Design occurs in complex socio-technical contexts with conflicting stakeholder goals, requirements and other constraints. These limit solution options and create trade-offs where improvements relative to one goal come at the expense of performance on another. Little is known about how the design context influences trade-offs, or how designers interact with context to manage trade-offs. This article reports on an exploratory qualitative interview study investigating design trade-offs in relation to their socio-technical context. We identified nine themes reflecting engineering designers’ perceptions of the influence of the design context on their ability to resolve trade-offs. Findings suggest that the design context is both a source of trade-offs, and of knowledge and information that helps designers clarify ambiguous requirements to navigate and resolve trade-offs. The results provide insight into how designers interact with the design context to learn about the structure of their design problems and the degrees of freedom available to resolve trade-offs. The findings also contribute to understanding the effects of path dependencies in trade-off situations, and how the sequential distribution of design decisions over time constrains trade-off resolution. We discuss some of the goals and challenges of conducting rigorous qualitative research in design and identify potential directions for further research.

Large organisations are designing complex technology-based tools for their staff to use. In busy workplace environments, it can be difficult to get user input about a design. This paper describes the designer and user interactions in one such organisation, gaining insights that could be useful in other similar settings. The findings are based on a set of interviews with designers and researchers within the organisation. The paper identifies the current practices and constraints involved in understanding and capturing users' needs and discusses potential solutions.

Challenges in implementing digital health in clinical practice hinder its potential. The complexities posed by implementation could benefit from using design practices. To explore the current role of design practices in digital health implementation, designers in the Netherlands were interviewed. The preliminary results indicate that designers contribute to digital health implementation processes, especially in the early stages. Design practices are mainly used for engaging the users, testing concepts, aligning the ideas of stakeholders, and adapting interventions to fit within the contexts.

The aim of this study is to identify: (a) challenges in understanding and using design methods, and (b) features expected in an enhanced repository of design methods, by design students. These are identified through interviews and a survey. The major findings are (a) less (time for) practice leads to weak understanding and challenges in using design methods and (b) students expect to have a method recommendation system based on problem context. The findings from this study will guide in developing a user-centric, enhanced repository of design methods to aid design practice and pedagogy.

eHealth development faces the challenge of generating evidence about health effectiveness in real-world settings. Designers can potentially support this challenge but must understand health approaches to evidence generation about health outcomes. This case study investigates how health and care professionals conceptualise health outcomes and their evidence generation in eHealth. Our results identify three key conceptual dimensions: effect, meaning, and collection. We discuss how these inform future design competencies to support evidence generation about health outcomes in eHealth design.

In this exploratory study, designers’ preferred learning media in learning to design for Additive Manufacturing was explored. Furthermore, by deploying an online survey questionnaire, factors such as years of experience, and the categories of products designed were explored to understand how they influence designers’ learning media with a response from 201 respondents. The results show that designers have learned how to design for AM through experimentation and present the first step towards developing an appropriate Design for Additive Manufacturing knowledge dissemination approach.

This paper contributes with insights regarding design expertise and prototyping. Seven high performers – Outstanding Designers – were interviewed to learn about their prototyping activities. The Outstanding Designers emphasised prototyping for reflection, gaining certainty, and cooperating with clients. They expressed a strong attachment regarding the use of prototyping that results in specific routines. We call this behaviour the Outstanding Designers’ bonding with prototyping. The main insights were synthesised into a model outlining the relation between design expertise and prototyping.

Assistive technology (AT) is any artefact that enables participation in activities usually limited by disability. Frequently, AT suffers from poor design engagement and utilisation. Moreover, up to 30% of all AT is abandoned within a year, negatively impacting users. This presents an ongoing challenge for occupational therapists (OTs) who work with assistive technologies. A literature review was conducted using a Preferred Reporting Items for Systematic Reviews and Meta-Analysis protocol to understand this issue and its implications for the design community. This study explores current themes of AT abandonment and the role of OT within the lens of design thinking. Studies, including design intervention in AT, were subsequently highlighted. This led to comparing this literature with more traditional health literature, exploring the potential enablers and barriers for design in engaging with AT. This evidenced the benefits of collaboration between design and OT disciplines to improve the product and reduce abandonment issues.

This paper aims to identify the reasons for neglecting and the motivations for using management tools among three groups of students participating in a project that was carried out and followed over a period of one semester. For this purpose, a survey in the form of questionnaires and interviews was created. Particular emphasis was placed on the use of project management methods, tools and techniques and respondents were asked to rate the effectiveness of their usage. Additionally, the participants were asked to report limitations or distractions they had encountered. The results revealed five aspects that mainly influenced the students’ motivation in using management tools: the team atmosphere, determining responsibilities, performance transparency, expectations by the supervisors, feedback and performance evaluation. On that basis conclusions were drawn on what actions can be taken to motivate future students and designers.

Sustainable Product Development (SPD) has been gaining increased attention in academia, industry, and policy. Over the past three decades, significant progress has been observed in incorporation of environmental issues into the product development process, through the so-called ecodesign management practices. Nevertheless, systematisation of the SPD practices, which simultaneously consider the environmental, social and economic dimensions of sustainability, is still missing. To address this gap, this research aims to identify the existing SPD management practices in the academic literature, with special focus on how sustainability dimensions are currently being considered, their coverage in relation to key knowledge areas for product development and their applicability across the SPD phases. Through a systematic literature review, 362 practices were identified and further classified according to a classification criteria. While environmental considerations are still the most prominent ones, the research highlights the importance of the early stages of product development for SPD, as well as the key knowledge areas which are currently being covered by the practices, such as sustainability evaluation and sustainability improvement.

The increasing importance of software as an essential functional provider in products and processes requires that companies master the development capabilities to continiously and quickly deliver high-quality software features. DevOps (acronym for Development and Operations) is an essential approach to these capabilities, which has so far been used predominantly in software-driven companies. This paper investigates the conditions under which DevOps can also be used in the industrial context of series manufacturing in order to be able to steadily develop and provide software features used in these environments (e.g. for monitoring and maintenance of manufacturing machines). A concept for DevOps for manufacturing systems was developed based on current best practices and the specific situation in the industrial company. The concept was then implemented and validated with experts on the basis of initial development cycles, demonstrating the usefulness of DevOps for manufacturing systems.

While a significant amount of research has documented the importance of design artefacts in design communication, relatively little work has investigated the effect of design artefact quality on the development of a shared understanding between designers. In the current work we focus specifically on sketch quality and the effect of sketch quality on the shared understanding of design dyads. A controlled study with 22 design dyads (44 designers) was conducted to understand the relationship between sketch quality and shared understanding. Results suggest that design artefact quality, measured by sketch understandability, does not predict the shared understanding of a design concept. Our findings hold implications for the fundamental ways in which we evaluate sketch quality and the importance of artefact fidelity for communicative acts.

The research of this paper provides a useful insight into the many barriers leading to building services overdesign, within the context of NHS hospitals. The issue of overdesign in building services is a systemic problem, whereby numerous contributing factors manifest into an issue that inevitably leads to poor system performance and excess costs. A key factor leading to oversizing is the excessive and uncoordinated application of design margins across the various stages of a building services project. Poor communication between project stakeholders is another significant barrier that inhibits the distribution of information between design groups; unknown requirements, system redundancy and poor system specifications further add to the problem. There are many complex interrelationships associated with the building service design process in hospitals, with external stakeholders adding to the complexity. This points to the importance of effective communication between stakeholders and clear contractual terms between NHS Trusts and external private sector organisations. Many of the barriers identified within this paper are by no means limited to building service systems but also impact on a range of other engineering disciplines.

Recently, methods and approaches such as Participatory Data Analysis, Data-Enabled Design, and Contextual Inquiry have highlighted how design activities can benefit from behavioral data. This data offers new ways to learn from what people do and how they do it, across time and space. However, behavioral data introduces changes and frictions to design activities and poses several challenges for designers to overcome. In this paper, we conduct two workshops with 18 expert designers, from industry and academia, to understand the nature of these challenges, beyond the technical aspects. We contribute by underlining the challenges and opportunities of incorporating behavioral data into design activities; including a design perspective on data, interacting with participants, and interacting with regulatory bodies. We translate our findings into opportunities for a better alignment between regulatory bodies, designers, and participants. We propose to harness the iterative nature of design activities and embedded it into a process that allows for continuous reflection, reassessment, and review of highly dynamic datasets.

The practice-led research focuses on how agro-waste can be used to build a structure, gather relevant knowledge, and identify its various challenges. Based on the compressive strength of Bio-Bricks, it was decided to use a frame structure, and instead of using Bio-Bricks as a modular unit, the material used was cast in situ with the help of a specially designed mould. The roofing of the structure was also built using Bio-Bricks material over an MS frame. The prototype was plastered with cement mortar and finished with two coats of distemper paint. After the completion of the prototype structure, comprehensive documentation was done to analyse the data generated from the process to identify the desired improvements. A secondary study of sustainable building materials was done to understand the comparative strength and weaknesses of Bio-Bricks as construction materials. Based on the work done at different stages of construction, detailed lists of findings and inferences were drawn to improve the overall manufacturing process. The research project findings will help guide the future development of Bio-Bricks as a commercial building material.

In the design studio, academic (professor) and practitioner tutors provide individual mentoring to students as they progress in their design projects. Prior studies suggest that design practitioners may follow a different design process compared to academics, but little is known about how this difference relates to their design tutoring. This study explores the similarities and differences in tutoring by academics and practitioners. We use a question-asking lens to characterize the tutoring styles of four tutors - two academics and two practitioners - over a five-week design project in an engineering design studio. We find that academic tutors ask questions at a significantly higher rate than practitioner tutors, suggesting a more question-centred tutoring style. We also find that proportionally more of practitioner tutors’ questions are generative in nature, while the academic tutors employ more convergent thinking in their questioning. This may be an indicator of the practitioners' own design thinking, which might be more solution-focused than that of academics. These preliminary findings motivate future investigations of the relationship between differences in tutoring and impact on student design learning.

The influence of culture on design is reflected in many aspects, such as design creativity, communication within design groups, and individuals' creative performance. Culture has a profound impact on design. For example, studies have identified the positive effect of a higher individualism-collectivism value on design team performance. To examine the influence of individual cultural values on the experience of creativity in ideation, we experimented by recruiting participants from different counties to complete two ideation tasks. Moreover, we collected their cultural values and experiences of creativity through two questionnaires. We also examined the connections between individuals' cultural values and their experiences of creativity in ideation. The results show five correlations between individuals' cultural values and their experiences of creativity when the country setting was a control variable. Recommendations based on the findings include that explorations of cultural influence and the relationship between culture and design or other fields irrelated to the country or society level have to measure individual cultural values (with the country setting as a control variable) instead of adopting country cultural scores.

The International Design Engineering Annual (IDEA) Challenge is a virtually hosted hackathon for Engineering Design researchers with aims of: i) generating open access datasets; ii) fostering community between researchers; and, iii) applying great design minds to develop solutions to real design problems. This paper presents the 2022 IDEA challenge and elements of the captured dataset with the aim of providing insights into prototyping behaviours at virtually hosted hackathons, comparing it with the 2021 challenge dataset and providing reflections and learnings from two years of running the challenge. The dataset is shown to provide valuable insights into how designers spend their time at hackathon events and how, why and when prototypes are used during their design processes. The dataset also corroborates the findings from the 2021 dataset, demonstrating the complementarity of physical and sketch prototypes. With this paper, we also invite the wider community to contribute to the IDEA Challenge in future years, either as participants or in using the platform to run their own design studies.

Evidence-based practices play an essential role in the development of eHealth systems. Prior research has investigated the challenge of shared understanding between professionals from the fields of health sciences and design and has highlighted the need for effective alignment of development and research practices in eHealth. However, there is a limited understanding of epistemological differences between these fields and how professionals conceptualise evidence. In this paper, we investigate how healthcare and design professionals think about evidence and how they implement evidence practices in their work. We interviewed eight professionals and used reflexive thematic analysis to identify the challenges and strategies associated with their evidence practices. Our results identify five shared evidence practices between healthcare and design professionals: stakeholder-driven, process-driven, problem-driven, effect-driven, and solution-driven. These five evidence practices indicate opportunities for closer alignment of development and research practices among healthcare and design professionals and offer a basis to create a shared understanding of evidence between both fields.
