Published: July 2019

Introduction

We investigated the relationship of plasma amyloid beta (Aβ) with cerebral deposition of Aβ and tau on positron emission tomography (PET).

Methods

Forty‐four participants (18 cognitively normal older adults [CN], 10 mild cognitive impairment, 16 Alzheimer's disease [AD]) underwent amyloid PET and a blood draw. Free and total plasma Aβ40 and Aβ42 were assessed using a validated assay. Thirty‐seven participants (17 CN, 8 mild cognitive impairment, 12 AD) also underwent a [18F]flortaucipir scan. Scans were preprocessed by standard techniques, and mean global and regional amyloid and tau values were extracted. Free Aβ42/Aβ40 (Aβ F42:F40) and total Aβ42/Aβ40 (Aβ T42:T40) were evaluated for differences by diagnosis and relation to PET Aβ positivity. Relationships between these measures and cerebral Aβ and tau on both regional and voxel‐wise basis were also evaluated.

Results

Lower Aβ T42:T40 was associated with diagnosis and PET Aβ positivity. Lower plasma Aβ T42:T40 ratios predicted cerebral Aβ positivity, both across the full sample and in CN only. Finally, lower plasma Aβ T42:T40 ratios were associated with increased cortical Aβ and tau in AD‐related regions on both regional and voxel‐wise analyses.

Discussion

Plasma Aβ measures may be useful biomarkers for predicting cerebral Aβ and tau. Additional studies in larger samples are warranted.
Societal Constitutionalism in Japan: Neighbourhood Associations as Micro-relational Constitutional Sites
Authors: SILIQUINI-CINELLI Luca
Published: July 2019

Over the past few years, Japan has been witnessing the emergence, regeneration, and spread of micro-relational forms of cohesion, solidarity, and responsibility in response to theryūdō-ka shakaiandhikikomoriphenomena. These terms refer to the crisis of social relations and co-operation, which commenced after the collapse of the Japanese economy in the early 1990s. While scholars, particularly sociologists and anthropologists, have consistently inquired into these micro-sites of civic friendship and responsibility, their juridical status is yet to be ascertained. This article argues that the paradigm of societal constitutionalism developed by Gunther Teubner can be of precious assistance in conducting such an assessment. In particular, it offers a contextualization of Teubner’s reflections on constitutional pluralism and fragmentation of social functions from the perspective of Kiyoshi Hasegawa’s state-centric scholarship on the regulatory dynamics of neighbourhood associations as micro-relational communities in suburban areas. A particular is given, and only given, within relations.1
A Law of Functional Expansion - Eliciting the Dynamics of Consumer Goods Innovation with Design Theory
Authors: Le Masson Pascal , El Qaoumi Kenza , Hatchuel Armand , Weil Benoit
Published: July 2019

For more than two decades, mobile phone industry has shown that innovation is not only functional optimization and combination but can also be a "functional expansion”. Sometimes called radical or disruptive innovation, this phenomenon leads to the development of new method for engineers and designers. However, the intensity remains undemonstrated: is functional expansion a rare phenomenon (few products during very short periods of time) – or is it an intense phenomenon, that even might have accelerated in the last decades? To answer these questions, the paper overcomes two main obstacles: how to measure functional expansion? And what would be a law of functional expansion, that would enable to test the importance and newness of the phenomena? Building on recent advances on the measurement of innovation and on new computational models of design derived from most advanced design theories, this paper presents unique data on functional expansion of 8 consumer products and tests that functional expansion significantly accelerated in the mid 1990s. The paper confirms quantitatively that our societies are now in a new design regime, a regime of innovative design.
A Matter of Factor: A Proposed Method for Identifying Factors that Influence Design Effort Levels in Product Design
Authors: Holliman Alexander , Thomson Avril , Hird Abigail , Wilson Nicky
Published: July 2019

Design effort, the amount of time required to complete a project or task (Salam et al., 2009; Salam and Bhuiyan, 2016), is a required resource for any design project which can be influenced by a number of factors. Estimating design effort is a significant challenge that can be mitigated through an understanding of these influential factors. This understanding is held as tacit knowledge by experts, earned through experience; yet, although these factors vary in type and impact, understanding their details can provide insight and improve future estimations. Some previous methods to estimate design effort identify these factors, either from: expert opinion, or historical data analysis with each approach has advantages and disadvantages.

This paper is comprised of three parts:

A review of published methods and tools for estimating product design effort and whether they consider and identify influential factors; an analysis of possible trends in the identification of factors influencing product design project length; and a new method for identifying the influential factors of product design project length.
Challenges and Architectural Approaches for Automotive PLM in Multi-Brand Organisations - A Discussion Paper
Authors: Kehl Stefan , Hesselmann Carsten , Stiefel Patrick , Müller Jörg P.
Published: July 2019

Today, top-down processes, centralized IT infrastructures, and one-vendor strategies prevail in Product Lifecycle Management (PLM) of large multi-brand Original Equipment Manufacturer (OEM) groups. Given the usually decentralized organisation and structures and processes that emerge from cross-brand collaboration, these centralized approaches are challenging the adaptiveness and performance of the OEM groups.

In this concept paper, we investigate challenges for cross-brand and cross-domain cooperation from the perspective of processes and IT systems. The main contribution of this paper is that we motivate and outline a novel technical architecture approach combining service-orientation with an event-driven software architecture and asynchronous event processing to support users from different brands and domains in their collaboration along the development process. We analyse related work on collaboration models as well as on event processing and discuss our approach before the background of the state of the art. Finally, we summarize our findings and give an outlook to future research venues.
Computational Simulation as an Organizational Prototyping Tool
Authors: Dosi Clio , Iori Manuel , Kramer Arthur , Vignoli Matteo
Published: July 2019

This case study deals with a redesign effort to face the overcrowding issue in an Emergency Department (ED). A multidiscinary group of healthcare professionals and engineers worked together to improve the actual processes. We integrate the simulation modeling in a human-centered design method. We use the simulation technique as a learning and experimentation tool into a design thinking process: the computational descrete event simulation helps explore the possibile scenarios to be prototyped. We used the simulation to create a virtual prototyping environment, to help the group start a safe ideation and prototyping effort. Virtual prototyping injected into the organizational context the possibility of experimenting. It represented a cognitive low-risk environment where professionals could explore possible alternative solutions. Upon those solutions, we developed organizational prototyping tools. Top management and head physicians gained confidence for a more grounded decision making effort and important choices of change management and investments have been made.
Empowering Decision Makers to Avoid the Oversizing of Building Service Systems
Authors: Jones Darren Anthony , Eckert Claudia Margot
Published: July 2019

Oversizing of building service systems has a direct impact on building efficiency and operational costs. The research of this paper highlights several major contributors to the issue of oversizing. A key factor is the excessive and uncoordinated application of design margins applied during the multiple stages of a building services project; others include, a lack of communication and transparency across the various stakeholder groups, and the use of vague or unreliable data upon which initial project requirements are based. The impact of these factors on system performance and cost, and how these can impede on a building's ability to meet energy efficiency targets are analysed and discussed.

The paper emphasises the need to develop robust processes that capture the scope and rationale for the margins applied, and to communicate this knowledge in a clear and unambiguous format, to all project stakeholders. The development of flexible and alternative design solutions that apply diversity principles, such as different backup systems to provide resilience rather than the traditional ‘like-for- like’ redundancy solutions, are also explored.
Experimentation Throughout the Product Development Process - Lessons from Food and Beverage Ventures
Authors: Kukko-Liedes Ville , Mikkonen Maria , Björklund Tua
Published: July 2019

Established companies turn to new ventures for bolstering exploration activities, but we know relatively little of the product development processes of startups and new ventures and how different stakeholders are utilized in these. The current study investigated the product development activities and experiments of eight Finnish food and beverage ventures in a multiple case study based on 22 interviews. How the developed products fit into the existing portfolio and experience of the ventures seemed to define their enacted development process. Internal experimentation was a constant feature, although the type of experiments varied between different phases of the development process. External-facing experiments were less frequent and more for validation than concept generation. On the other hand, they also carried important market creation functionalities. The results suggest that more nuanced terminology around experimentation would be useful to determine what type of experiments serve different goals in the development process.
Interdependencies Within the System of Objectives of a Product Generation in Industrial Practice
Authors: Albers Albert , Peglow Natalie , Spadinger Markus
Published: July 2019

One challenge in product development is the megatrend of product individualization in the automotive supplier industry. Requirements for a variant by the customer may differ from those by the provider wherefore conflicting goals can arise. To cope with variant requests in the quotation phase systematically, a method to evaluate variants is necessary. Based on evaluation criteria the requirements from the stakeholders are valued. While evaluating, an already criterion can have an impact on assessing the remaining criteria. For this reason, the present investigation emphases the interdependencies between the evaluation criteria in industrial practice representing interdependencies within goals, requirements and boundary conditions in an early stage of product development. Analysing decisive factors supports to identify subsequent activities in the development process of a variant. Experts of an international automotive supplier developed impact matrices and a scenario technique tool is used to interpret the matrices. In context of the model of PGE - Product Generation Engineering, findings derive to ensure a comprehensive basis for decision-making concerning a variant-request.

Relevant theoretical concepts of organizational theory, design approaches and practices are discussed to evaluate gaps in management practices and potential opportunities for design practice. The study collected and analyzed data from two organizations. The researched revealed several propositions, which provide insights of the usefulness, appropriateness and value of a human-centered design practice to organizational design.
The Design Process at Le Corbusier, Case of the Ronchamp Chapel
Authors: Outmoune Nadjat , Arrouf Abdelmalek
Published: July 2019

This work falls within the empirical studies of design activity. Its project is to understand Le Corbusier's designing way and how does he work and structure his design processes. Doing so, it jumps above the descriptive and doctrinal knowledge of objects produced by “Le Corbusier” to study the actions and mechanisms that led to them.

To achieve its aim, this study uses genetic method, developed by P.M. De Biasi of literary origin, this research method is made of three stages. The first one, which is of empirical nature, is one of data gathering. It leads to the establishment of genesis tables and to the classification of the all collected documents. The second stage, makes the analysis of all the collected documents one by one. It allows the restitution of the creative process of one projects “Le Corbusier” which is “la chapelle de Notre Dame du haut de Ronchamp”. The last stage is finally that define the design processe of the this project. The results show that the design activity of “Le Corbuiser” obeys the overall logic of one generic model which may be called his individual designing style.
Designing Physical-Digital Workspaces to Support Globally Collaborative Work
Authors: Tucker Andrea , Gidel Thierry , Fluckiger Cédric
Published: July 2019

This paper examines some aspects of physical-digital workspaces, focusing on multi-user, multi-touch technologies and how different workspaces impact collaboration. We introduce the concept of globally collaborative work. We chose to use case studies completed by groups of students in an engineering course to test different workspace modalities: the use of a large multi-touch table top in conjunction with a multi-touch board (vertical), the use of tablets with the multi-touch board, and finally the multi-touch board alone. The evaluation criteria are based on modes of interaction which emerge during globally collaborative work sessions: individual work, communication, coordination, cooperation and collaboration. We hypothesized that the workspaces would influence collaborative activity, expecting to see higher rates of collaboration in the table top environment than in the other two modalities studied. However, results showed less co-building and more cooperative work, as students divided their work and later attempted to negotiate a coherent product built on individual contributions. Lastly, we share a few design recommendations based on these results.
Assessing Concept Novelty Potential with Lexical and Distributional Word Similarity for Innovative Design
Authors: Nomaguchi Yutaka , Kawahara Takahiro , Shoda Koki , Fujita Kikuo
Published: July 2019

Generating novel design concepts is a cornerstone for producing innovative products. Although many methods have been proposed for supporting the task, their performance depends on human ability. The goal of this research is to build a method supporting designers to generate novel design concepts with the knowledge of what factors have positive effects on the novelty. Toward the goal, this research assumes that the more distant two function concepts chosen, the more novel idea would come up with by the combination of the two concepts. Based on the assumption, this paper introduces a notion of novelty potential of the combination of two function concepts, and proposes a method to assess it by the function similarity. It is calculated with the integration of a lexical database for natural language called WordNet and a distributional semantics method called word2vec. The proposed method is adapted to case studies in which students perform design concept generation for given design tasks. The correlation analysis is performed to verify the assessment performance of the proposed method. This paper discusses its possibility based on the results of the case studies.
Design Thinking: An Approach with Various Perceptions
Authors: Bouwman Sanne , Voorendt Jesper , Eisenbart Boris , McKilligan Seda
Published: July 2019

Design Thinking has become increasingly popular across different disciplines. However, what it exactly entails is becoming more and more vague, leading to the term being used for many different approaches and applications. This paper presents an interview study with experts on the application and training of Design Thinking in academia and industry. We find a divide with some seeing Design Thinking as a mere toolbox of methods, while others see it as an umbrella term for the mindset that determines how designers think and act. Subjects unanimously attest the approach large potential to support certain types of businesses, when applied under the leadership of trained designers, but see a lot of danger for the approach to become meaningless if it keeps being advertised as an all-purpose problem-solving tool. The interviewees further share extensive experiences on specific success factors and pitfalls in applying Design Thinking in practice.
French Biological Philosophy of Technology as a Candidate Perspective Furthering Design Methodology
Authors: Mulder Sander
Published: July 2019

A first exploration is conducted to what the French biological philosophy of technology perspective has to offer to the field of design methodology. If this French perspective is combined with contemporary speculative pragmatism a generative design methodology emerges offering novelty in what is sensed as important in a design situation. Within this perspective, drawing upon the late French philosopher Gilbert Simondon, technical objects have their own mode of existence and their own trajectory of development apart from human intention.

Designers working with such a generative design methodology follow the constitutive value of openness and attune to the regulative value of techno-aesthetic judgments. By way of a 'vignette+', a paradigmatic example from a real case, a more encompassing argument is made towards design situations where a sophisticated machine is 'inserted' into a domestic setting.

The example taken is the use of an artificial kidney machine in a domestic setting and the development of a novel machine with a design team. Four aspects were sensed as important in the unfolding design situation and directions for further research are discussed.
Prototyping Canvas: Design Tool for Planning Purposeful Prototypes
Authors: Lauff Carlye , Menold Jessica , Wood Kristin L.
Published: July 2019

While prototypes are critical to the creation of successful products and innovative solutions, building a prototype is characterized by large sunk costs and a plethora of unknowns. The versatility and effectiveness of prototypes paired with the ambiguous nature of developing a prototype can lead to wasted resources. Recent studies support this claim, demonstrating that under certain circumstances, designers often prototype without a clear purpose, building prototypes as a function of the design process rather than as a function of the design. These findings motivated the creation of the Prototyping Canvas, a tool to aid designers in planning for purposeful prototypes by identifying critical assumptions and questions to guide development. Business and engineering design literature influenced the development of the canvas, which was first tested with a client project in the SUTD-MIT International Design Centre (IDC). The feedback and insights from the design team guided revisions to the canvas. The updated canvas was then validated with 55 professionals during a design project sprint. The purpose of this paper is to present the Prototyping Canvas as a valid and effective design tool.
Reverse Engineered Design Automation: Applying Knowledge Based Engineering Techniques to a Case of Automotive Fixtures Design Configuration
Authors: Johansson Christian
Published: July 2019

In the production of automotive body components, fixtures are an important part of the ongoing work on geometrical assurance. The fixture is uniquely defined for each component, and the design and configuration of these are time-consuming and takes a lot of effort. The objective with this paper is to explore the use of a design automation approach and application to semi-automate the configuration process of the fixture product. The paper presents an approach to automate the configuration of the fixtures in a flexible way, by reverse engineering the configuration of the fixture product from a generic blueprint that represents the expected outcome of the process, using a knowledge-based engineering approach applied to a computer aided design (CAD) environment. A reverse-engineered design automation toolbox for a CAD-software is developed. The toolbox is developed to lead a user through the configuration process, in the way that the experts want it done, end-to-end, making use of some unconventional solutions from a design automation perspective.
The Cost of Learning from Failures and Mistakes in Product Design: Reviewing the Literature
Authors: Shafqat Ali , Oehmen Josef , Welo Torgeir , Willumsen Pelle
Published: July 2019

In the design phase of product development (PD) process, most new products face significant uncertainties and risks. Uncertainty is typically associated with a lack of information, while learning is a process that acquires information. Therefore, learning fast and at low cost decreases the uncertainty and increases the efficiency of the product design phase. This paper investigates the concept of the cost of learning in PD's design phase. Reviewing the literature, we conceptualize the cost of learning and review the learning methods considering three aspects in the design phase of the PD process: (1) costs associated with learning from mistakes and failures, (2) learning methods and (3) categories of learners. This paper thus provides the conceptual foundations for future work to increase the efficiency of the PD process by reducing the cost of learning from mistakes and failures.
A Neutral Form for Experiential Material Characterisation
Authors: Veelaert Lore , Moons Ingrid , Rohaert Sarah , Du Bois Els
Published: July 2019

Materials experience in design involves the meanings that materials convey to users through its expressive characteristics. Such meaning evoking patterns are influenced by parameters such as context, product (e.g.shape) and user. Consequently, there is a need to standardise experiential material characterisation and large-scale data collection, by means of a meaning-less or ‘neutral’ demonstrator to objectively compare materials.

This paper explores the conception of this neutrality and proposes two opposing strategies: neutrality through complexity or through simplicity. In a pre-study with 20 designers, six associative pairs are selected as neutrality criteria, and shaped in 240 forms by 20 (non) designers in a main workshop. Following the simplicity strategy, these forms are averaged out in three steps by a team of five designers, based on a consensus on of delicate-rugged, aggressive-calm, futuristic-calm, masculine-feminine, traditional-modern, and toylike-professional, resulting in a selection of four averaged neutral forms.

Finally, future research will focus on complexity to increase interactivity, so that consumers might be triggered in extensive material exploration.
Exploring the Effect of Combinational Pictorial Stimuli on Creative Design Performance
Authors: Hua Min , Han Ji , Ma Xuezi , Childs Peter
Published: July 2019

Visual stimuli can be useful in supporting design ideation process. However, researchers still know very little about how stimuli should be delivered to designers during the early design stage. This question is crucial to the effective use of stimuli because previous researches have proved that ill-presented stimuli can have a negative impact on design creativity. Therefore, an empirical study was conducted with the aim of exploring if and how combinational pictorial stimuli can affect designers' creative performance. Results from a total of 36 participants show that the design outcomes presented by the group exposed to combinational pictorial stimuli were more creative than those given by the group exposed to no stimuli or randomly presented pictorial stimuli. These results imply that the form of stimuli delivery can affect creative design outcomes and combinational pictorial stimuli best support design creativity among these three conditions. These findings give us a better understanding of the roles that visual stimuli play in design, which is expected to bring us important implications for both design education and design support tool development
The Neurocognition of Three Engineering Concept Generation Techniques
Authors: Shealy Tripp , Gero John
Published: July 2019

Techniques and processes used for concept generation rely on composing new concepts and analysis given situational context. Composition and analysis require distinct neurocognitive function. For instance, jazz composition relies heavily on the right brain, while math relies on the left. Similar to music and math, is concept generation hemisphere dominant? What differences exist when using varying techniques? Twelve graduate engineering students were given three design tasks and instructed to use brainstorming, morphological analysis and TRIZ. A device called fNIRS measured cognitive activation. The results find left hemisphere dominance. More specifically, the left dorsolateral PFC (dlPFC), which is central to spatial working memory and filtering information. Temporal differences do exist. Morphological analysis and TRIZ reinforced the use of the left dlPFC, while brainstorming increased the use of the right dlPFC and medial PFC (mPFC) late during concept generation. The right dlPFC contributes to divergent thinking and mPFC facilitates memory retrieval. One explanation is designers relaxed rule constraints and more deeply searched for associations during brainstorming.
Enabling Designers to Generate Concepts of Interactive Product Behaviours: A Mixed Reality Design Approach
Authors: Maurya Santosh , Takeda Yukio , Mougenot Celine
Published: July 2019

To design interactive behaviours for their products designers/makers have to use high fidelity tools like ‘electronic prototyping kits’, involving sensors and programming to incorporate interactions in their products and are dependent on availability of hardware. Not every designer is comfortable using such tools to ideate and test their concept ideas, eventually slowing them down in the process. Thus, there is a need for a design tool that reduces dependence on complex components of such tools while exploring new concepts for product design at an early stage. In this work, we propose a Mixed Reality system that we developed to simulate interactive behaviours of products using designed visual interaction blocks. The system is implemented in three stages: idea generation, creating interactions and revision of interactive behaviours. The implemented virtual scenario showed to elicit high motivation and appeal among users resulting in inventive and creative design experience at the same time. As a result, designers will be able to create and revise their interaction-behavioural design concepts virtually with relative ease, resulting in higher concept generation and their validation.
Method Toolbox for the Multidisciplinary Planning and Development of Adaptive Buildings
Authors: Honold Clemens , Leistner Sophia , Roth Daniel , Binz Hansgeorg , Sobek Werner
Published: July 2019

Adaptive buildings constitute an interdisciplinary approach for realizing the next generation of buildings in order to reduce the immense material requirements and energy demand throughout all lifecycle phases. Based on a novel cooperation between the disciplines of Architecture and Civil and Mechanical Engineering, adaptive support structures and skins are developed within the Collaborative Research Centre SFB 1244. A holistic planning process is required in order to reduce the high complexity and achieve a goal-oriented procedure during the planning of such buildings and the development of integrated systems.

Part of this research is the development of new specific and the transfer of established methods from different disciplines. The experience gained during the planning of an adaptive, high-rise demonstrator building within the research project has shown that the methods for application must be provided in the form of a method toolbox to present their purpose, application time and results within the planning team. Based on the examination of existing method toolkits, this paper focuses on the development of an approach while considering context-specific requirements.
Estimating the Impact of Design Automation: The Influence of Knowledge on Potential Estimation
Authors: Rigger Eugen , Lutz Alexander , Shea Kristina , Stankovic Tino
Published: July 2019

Assessing the impact of design automation on design practice prior to its implementation is difficult and subject to uncertainties. One reason for this is the designers' lack of knowledge about design automation. In this work, an industrial case study focusing on conceptual design of hydraulic circuits is conducted to assess the impact of the designers' knowledge on design automation potential estimation. In particular, the impact of demonstrating a prototypical implementation of a design automation application is investigated as a means to enhance the designers' knowledge about design automation. In this respect, a given set of metrics is rated twice to enable a comparative study: prior to and after introducing the design automation prototype. The yielded results show that the knowledge impacts the rating and supports reliability of potential estimation. Further, it is shown that designers acknowledge design automation potential for the early stages of design given sufficient knowledge about design automation. Yet, the results also indicate that careful attention needs to be put on the aspects covered by the prototype in order to avoid biasing participants.
Perceived Quality Evaluation with the Use of Extended Reality
Authors: Stylidis Kostas , Dagman Andreas , Almius Håkan , Gong Liang , Söderberg Rikard
Published: July 2019

If designers want to communicate quality aspects of the product, there is a need to bring these characteristics into the measurable space of perceived quality (PQ) attributes. To illustrate the solution for designers' dilemma of the “best design choice” in this study we applied the PQ attributes importance ranking (PQAIR) method, with the example of a bread toaster. We choose for evaluation three PQ attributes which can significantly influence visual quality of a product: Gap, Flush and Parallelism. We performed the experiment measuring subjective preferences over the toaster designs of two respondent's groups - “Designers” and “Customers.” We used sequentially: (i) web-survey (still images); (ii) desktop system; and (iii) fully immersive head-mounted display system (Virtual Reality).

Consequently, we conducted a post-experiment survey regarding subjective preferences, related to the PQ communication channels that have been implemented during the study. Our results indicate advantages and drawbacks for each PQ communication method that we applied in this experiment and encourage further research in the area of products' perceived quality assessment
Shedding Light on Game Engines and Virtual Reality for Design Ideation
Authors: Ekströmer Philip , Wever Renee , Andersson Patrik , Jönsson Johan
Published: July 2019

While pen-and-paper sketches is generally considered the best tool for design ideation, there are certain areas of design where the ideas being generated do not easily lend themselves to sketching. This study reports on two cases that explores the use of game engines in combination with Virtual Reality (VR) to visualize lighting in the automotive industry. In the first case, the exterior lights of a car were visualized using Unreal Engine 4 and evaluated using research through design and expert interviews. In the second case, Unreal Engine VR Editor was used to explore ideation and concept development of interior lighting in long haulage trucks. The insights from the cases suggest that game engines and VR can be used to quickly develop and display ideas, concepts and scenarios in the early phases of the lighting design process. These strengths suggest that game engines and VR also have the potential to support design ideation for other types of design.
Supporting Creativity with Virtual Reality Technology
Authors: Graessler Iris , Taplick Patrick
Published: July 2019

This contribution includes the development and validation of a Virtual Reality (VR) supported creativity technique: “Sensory Stimulus Environment Technique”. Key elements of this technique are the creativity process, a VR tool and the support of the tool (Virtual Creative Environments). The creativity process consists of phases for individual and group-based work. The VR tool “Virtual Creativity” includes functions to support the preparation of Virtual Creative Environments (VCE), the generation and evaluation of new ideas. For the generation of VCE, the tool possesses an environment configurator. Users of this function are supported by Design Rules for VCE.

For the validation of the creativity technique, it was used in a product engineering project. The project members procedure two phases of the creativity process (Preparation and Individual Idea Generation) and used “Virtual Creativity” to generate VCEs and ideas to solve their tasks. By questionnaires, functions of “Virtual Creativity” were assessed for generating VCEs and ideas.

Budgeting for Agile Product Development
Authors: Vierlboeck Maximilian , Gövert Kristin , Trauer Jakob , Lindemann Udo
Published: July 2019

Recent reports and predictions indicate a consistent and continuous growth in the field of Research and Development. Such growth leads to increased resource investments, which have to be managed effectively to eventually achieve value maximization. This management is cohesive with budgeting. In changing environments, said effectiveness can be difficult to attain.

Agile development is supposed to provide the necessary flexibility for uncertain situations and has recently seen a stark adoption incline. Unfortunately, budgeting and resource allocation have not yet been resolved for agile approaches: a comprehensive research including recent publications showed a lack of models and frameworks for the adoption and application of budgeting with agile development. Due to this lack of a comprehensive approach, as well as limitations and restrictions of existing research, this paper describes the design of a budgeting approach suitable for and compatible with agile product development. The developed solution, the Structured Agile Budgeting Process, provides a holistic and interdisciplinary way to allocate resources while still allowing the flexibility and benefits of agile development.
How to Foster Innovation? A Methodology to Identify Fields for Fostering Innovation Capability in Small and Medium-Sized Enterprises
Authors: Şahin Tarık , Riedel Leonhard , Inkermann David , Wilgeroth Dagmar , Asghari Reza , Vietor Thomas
Published: July 2019

Small and medium-sized enterprises are affected by changing development, production and selling paradigms in globalized industries, where innovation is a driver for sustainable competitiveness. However, innovating is highly challenging for small and medium-sized enterprises, as human resources are very limited and know-how are often highly specialized. It is often unclear which fields and factors provide the capability to innovate and which measures or methods can be applied to promote innovation based on existing competencies.

For this reason, the aim of this paper is to present a framework to support the innovation capability of SMEs by identifying promising fields for innovation and providing suitable innovation methods. A particular focus in this paper is a methodology for the description and identification of fields to foster the innovation capability in SMEs as a part of the introduced framework.
Interview Study on the Agile Development of Mechatronic Systems
Authors: Goevert Kristin , Heimicke Jonas , Lindemann Udo , Albers Albert
Published: July 2019

In order to be as responsive as possible to changes in the dynamic context of mechatronic system development, companies are increasingly integrating agile approaches into their development processes. They are confronted with the challenges of adapting approaches that originate in software development to the conditions of physical development, without neglecting the experiences gained over many years regarding product and process knowledge. In addition, agile development approaches must be integrated into existing processes through a systematic implementation strategy. In order to gain an initial understanding of the current situation in mechatronic companies with regard to agile development approaches, an interview study was conducted with 18 participants from real development practice. This could show that the companies in mechatronic system development are currently at the beginning of agile transformation and need approaches that are modelled on the basis of real development projects and are best possible tailored to the needs of these companies through a clear technical orientation. The findings gained are not universally valid, but represent a basis for further research work.
Open Source Hardware Communities: Investigating Participation in Design Activities
Authors: Boujut Jean-François , Pourroy Franck , Marin Philippe , Dai Jason , Richardot Gilles
Published: July 2019

Open source design of hardware products is an emerging phenomenon that takes more and more importance today's in the society. However, open source (hardware) design implies a tremendous change in both design practices and philosophy because it is partly related to the movements of creative commons and the sharing economy. From this perspective one could think that participation is crucial in the success of open source design projects. In this paper, we analyse 9 case studies in the light of 3 hypotheses. If many studies highlight the potential of the crowd as a resource for design tasks, our study shows that for open source design communities the participation is not massive. In this study, we used an activity-based approach to build our model. As open source design processes are fairly unstructured and based on voluntary participation, it is impossible to adopt a classical task-based model. With the help of this model, we were able evaluate the overall size of the active community, the participation rate with regards to the activities. This study paves the way to deeper and extensive studies on how to support communities engaged in open source design of hardware products.
Orienting through the Variants of the Shah’s A-Posteriori Novelty Metric

Different variants of a-posteriori novelty metrics can be found in the literature. Indeed, such a kind of assessment procedures is often used to extract useful information about creativity and/or idea generation effectiveness. In particular, the metric proposed by Shah et al. in 2003, is one of the most used and discussed in the literature. However, scholars highlighted some flaws for this metric, and some variants have been proposed to overcome them. This paper argues about the variants proposed for the a-posteriori metric of Shah et al., and proposes a selection framework to support researchers in selecting the most suited for their experimental needs. The proposed selection framework also highlights important research hints, which could pave the way for future activities. More specifically, it is still necessary to support the identification of the best-suited abstraction framework to assign weights to attributes, and the assignment of weights should be better supported as well. Moreover, this paper highlights the presence of “uncommonness of key attributes”, which needs to be investigated for experimental cases where ideas missing some key attributes are present.
Studying Design Thinking as a Forthcoming Source to Innovation Speed

With complex technology-intense industries follows an ever-increasing need for rapid innovation processes. Yet, innovation speed and the time from idea to product realization can vary and be unpredictable.

Design Thinking (DT) is suggested as a key driver to impact the speed of product innovation within product development projects. To understand and aid the road from early ideas and concepts to value- added products, this paper will provide a literature study on how Design Thinking can facilitate improved product innovation performance through innovation speed.

The paper seeks to develop an overview of new insight on DT applicability for improved product innovation capability. This is done by identifying components that comprise DT´s innovative ability and appropriateness to product development contexts beyond the early creative phases of product development.

As DT emphasize on visualization and re-framing problems, it contributes to enhanced clarity, meaning and confidence in ideas and decisions. DT in this way may impact strategy formulation and speed up complex innovation processes by pre-experiencing future situations.
The Economic Explanation of Inclusive Design in Different Stages of Product Life Time

The static data obtained from user research are not sufficient to accurately reflect the change of the user's needs and capabilities in different contexts. Not paying enough attention to the economic feasibility of design solutions makes inclusive design face challenges in commercialization. In this paper, the user's demand is regarded as a function of the dynamic interaction between the user's characteristics and the environment. The inclusion problem is defined from an economic perspective. By distinguishing the stages before and after the delivery of a product, different economic properties of the product are defined. Then the two stages are analysed from the perspective of investment and consumption respectively, and the competition criterion of inclusivity distribution and the reasons for exclusion are deduced. According to the causes of different problems in the two stages, the research direction of inclusive solutions is pointed out, and the economical sustainability of inclusive design is analysed. This paper emphasizes that the goal of inclusive design lies not only in the partial and temporary elimination of exclusion, but also in how to distribute the freedom of choice.
Toward Better Design-Related Decision Making: A Proposal of an Advanced OODA Loop

To be successful in innovation, organisations need to be dynamically adaptable to novel situations to avoid getting ‘left behind’. Yet, they face vast uncertainties stemming from unforeseeable technological shifts or future user and market behaviour, making strategic decision-making on innovation an extremely difficult task. Decision-makers thus increasingly try to control or shape the future, rather than foresee it. This includes thinking ahead and generating potential pathways that will make an innovation viable. This captures the essence of designerly ways of thinking in reasoning toward ‘what might be’. Extant literature has been reviewed that discusses alternative strategies how this future-oriented thinking can be applied to become better at selecting novel ideas for development. We observe parallels between divergent thinking, abductive reasoning, analogising and lateral thinking suggested by different authors in this process. The paper continues to propose how these key mechanisms can be embedded within an existing framework for decision-making under uncertainty, the ‘OODA Loop’, which has seen increasing uptake in such decision-making scenarios.
Value Driven Design Revisited: Emerging Modelling Concepts and Applications

Published: July 2019

Extended product warranties, leasing, and pay-per-use schemes are few examples of how manufacturing companies are shifting their focus from selling products to offering “solutions”, combining products and services to maximise customer value. The idea of optimising a system towards the best ‘value’ is both “intuitive and sensible”, and processes such as Value Driven Design (VDD), have been proposed to supplement traditional engineering design methodologies. Yet, value-driven initiatives struggle to communicate their benefits and to demonstrate how value models can solve actual problems. The aim of this paper is to shed light on the evolution of the VDD toolbox, mapping research clusters, applications and case studies from the perspective of how much (and how well) recent contributions have answered the five top-level questions of the VDD research agenda published in 2012. The results of the systematic literature review reveal the emergence of innovative modelling constructs, methods, and tools that help VDD in taking a leap forward in supporting organizations and teams in achieving the long-sought objective of designing for 'value'.
