• Developed a comprehensive set of correlations between design parameters and repair efficiency metrics, providing actionable insights for designers and manufacturers. • Demonstrated the crucial interplay between technical design aspects (e.g., modularity, diagnostic tools) and human factors (e.g., clear labeling, safety measures) in enhancing product repairability. • Identified strong correlations between user-friendly design elements and repair efficiency, addressing the skill gap in self-repair and potentially increasing user engagement in repair activities. • Highlighted the importance of incorporating product lifecycle information into the design process, offering a proactive approach to facilitating future repairs. • Provided quantitative evidence linking design parameters to repair outcomes, offering a practical framework for implementing circular economy principles in electronic product design. Increasing product lifespan via its repairability has become a key pillar of sustainable design, however, the existing initiatives remain scattered and fall short in equipping stakeholders for facing with real repair problems of electronic products. Current circular design guidelines and repairability standards predominantly address technical aspects such as disassembly protocols and do not consider human-factor impediments that arguably have the most significant effect on repair outcomes on the shop floor. To bridge this gap, the present research introduces a holistic repair-oriented design approach merging the technical and user aspects in the concept design stage to support predictable repairability and circularity. A structured checklist was created to operationalize this framework, which allows designers and manufacturers to quantitatively assess electronic products on a scale the repair after previous repair influencing parameters of accuracy, accessibility, speed, safety, fault diagnosis and user skill support. The checklist was validated through expert assessments from professional technicians and examined across a diverse set of electronic consumer products. Reliability analysis using Cronbach’s alpha confirmed acceptable internal consistency. Correlational analysis by testing 86 significant positive and negative correlations among the 703 comparisons provided evidence of multiple positive and negative relationships among parameters, revealing how specific design decisions may simultaneously facilitate or hinder different aspects of the repair process. These findings demonstrate the importance of balancing both technical architecture and user interaction within product design to achieve effective reparability. This circular design study provided practical design priorities and offers actionable guidance for enhancing sustainable practices in future electronic product development.

Three-dimensional (3D) technologies such as 3D digital prototyping have recently been used in apparel engineering to reduce the number of costly physical prototypes. This technology can simulate garment drapes by digitally sewing 2D patterns and placing them on a 3D avatar. Yet, current limitations in simulation accuracy mean physical prototypes are still indispensable. Integrating AI technologies shows promise in accelerating digital transformation in the apparel industry. AI can support decision-making in apparel design, size and fit prediction, and fashion recommendations. It can also assist decision-making in technical design by predicting garment fit before making physical prototypes or offering solutions for misfit areas. Research indicates that models such as Naive Bayes (NB), Support Vector Machine (SVM), and Artificial Neural Networks (ANN) offer robust solutions for fit evaluation. However, they require further testing across diverse garment styles and demographics. Developing a nuanced classification system for fit conditions could improve model accuracy, ultimately supporting the industry's shift towards digital and AI-enhanced product development. In this study, we propose a framework to achieve such a system.

This research addresses the limited exploration of hybrid processes for customer co-created new product development (NPD) involving cross-functional teams. While existing studies often focus on individual elements like hybrid NPD processes, customer co-creation, or cross-functional teams, this study combines all three. This research develops a unique design-oriented framework tailored for the Swiss media industry. It employs the design science research (DSR) process and a multi-phase qualitative research design, encompassing the five largest Swiss media companies. Data was collected through three interview phases of ten interviews, with five Swiss media companies embedded within. An inductive-deductive approach guided the data analysis along the DSR process, culminating in the development of a design-oriented framework of this study. This study has four key findings. Firstly, customer co-creation is not widely used in the Swiss media industry due to misunderstandings and perceived obstacles such as resource constraints. Secondly, agile methods in product development often deviate from theoretical ideals, especially when implementing scrum. Thirdly, product managers are central to product development, but there is a lack of clarity regarding the distinction between product managers and product owners. Fourthly, the Swiss media industry is lacking a structured process for crucial NPD elements: overarching structure, technology, and quality control. This research contributes to theory in three ways. First, it develops a design-oriented framework for hybrid NPD structures, merging application lifecycle management with design thinking, user-centred design, stage-gate processes, lean start-up methodologies, and scrum. Second, it explores customer co-creation barriers, highlighting the interplay of motivation and collaboration, the importance of dedicated communication management, and context-specific social media limitations. Third, it outlines cross-functional roles and structures across the entire NPD process, offering a broadly applicable framework for NPD of digital products.
