Early Stage Design

In the early stages of a product development process (PDP), VR can facilitate communication between designers and product end-users to improve the quality of feedback that user provide to designers. While various forms of VR can already be found in the PDP, they primarily target designers, rather than designers and end-users. Furthermore, available tools and toolkits do not match the skills and requirements of designers in early stages of the PDP. The current paper presents an approach that first identifies how to effectively support early stage design activities (referred to as the application) and subsequently provides designers with tools to realize this application themselves. The approach is implemented in an industrial case study involving practitioners from a multinational manufacturer of printing solutions for professional markets. The Virtual Printshop resulting from this case study provides an evaluation platform for various types of early stage product evaluations. A concluding generalization of the cases study results shows that the application can be translated to several other design domains. Furthermore, it was found that there are similarities in how these different design domains integrate VR design tools with their existing tool chains.

Early Stage Design

To reduce the energy and resource consumption in the building sector this study is focusing on a design optimisation of life cycle oriented buildings. In order to optimise the performance of the buildings and in consequence also to achieve improved results for the mandatory Austrian energy certificate a simulation-based rapid design approach is used for the early stage design phase of the buildings, in particular for the architectural design of the buildings.Methods like the Window to Wall Ratio, at the very beginning of the design process, a parametric simulation with EnergyPlus or a more detailed optimisation approach with GenOpt are integrated in this study applied to example buildings. The results are showing that the method can be used in a circular approach for improving the heating demand of the Austrian energy certificate for this case study by more than 25 % compared to the preliminary design

New Product Development Process

Disciplined product development has been a hallmark of mature companies for many decades, resulting in shorter development cycles, reduced costs, and higher quality products. Unfortunately, these tools and processes have typically been applied in large, well-established firms, not start-up companies. In this paper, we describe a simplified new product development process for early-stage firms and its application to a consumer product in which the process was executed during a 14-month development cycle. The process consists of 15-steps in 3-phases, two decision gates, and provides a step-by-step guide for development, with specific call-outs as to what, when, and where tools such as market segmentation, platform planning, industrial design, and cost modeling should be applied. The proposed process is applied to design a new consumer product, and the case study results are discussed with specific emphasis on costs, duration, and applicability of the process and its related engineering tools. Finally, we conclude with comments on the limitations of the proposed process, potential improvements, and future work.

Conceptual sketches of design alternatives are often employed as a tool for eliciting feedback from design stakeholders, including potential end-users. However, such sketches can vary widely in their level of finish and style, thus potentially affecting how users respond to a concept. This paper presents a study of user responses to three objects drawn in styles ranging from rough hand sketches to CAD drawings. This study also considers the amount of design time required to create the sketches. Results show that respondents generally ranked realistic, “clean” hand sketches the highest over other types of sketches, particularly “rough” sketches. These types of sketches took longer than other types of hand sketches to create, but were still much faster than CAD renderings. Results also suggest that the complexity and familiarity of an object can influence how users respond to a sketch.

The Difference

Early-stage interventions in a potential pandemic are important to understand as they can make the difference between runaway exponential growth that is hard to turn back and stopping the spread before it gets that far. COVID-9 is an interesting case study because there have been very different outcomes in different localities. These variations are best studied after the fact if precision is the goal; while a pandemic is still unfolding less precise analysis is of value in attempting to guide localities in the early stages to learn lessons of those that preceded them. I examine two factors that could differentiate strategy: asymptomatic spread and differences in use of the Bacillus Calmette-Guerin (BCG) tuberculosis vaccine. These differences point to the possibility of alternative strategies to prevent COVID-19 from entering the runaway phase. The most promising is testing all contacts of anyone who has tested positive, not only those who are symptomatic. Should this demonstrate asymptomatic transmission, then all contacts of anyone who tests positive should be isolated and tested, and only released from quarantine when it is clear that they are past incubation and not positive.

The Impact

AbstractAssessing 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.

Abstract This paper presents a technique to obtain a Design Structure Matrix (DSM) from a Design Matrix (DM). This technique enables us to obtain the design information flow pattern at early stage of the design, and apply the DSM system analysis and management techniques at the time when the most important decisions about the system and the design are made. The validity of this method is proven using a case study on the design integration process of an electrostatic chuck used in semiconductor wafer processing. The algorithm underlying this technique is also proven logically and mathematically to be valid.

Providing memorable tourism experiences (MTEs) plays a crucial role in determining the competitiveness and sustainability of a destination for not only the business sector, but also the environment. Therefore, destination managers face a challenge in identifying, facilitating, and maintaining memorable tourism experiences among visitors. Although MTEs have been increasingly studied, research of the effects of MTEs on word-of-mouth and revisit behavior intentions is still at an early stage of development, particularly in the forest recreation context. The objectives of this study were twofold: To assess visitors’ MTEs in a selected forest recreation destination and to examine the effects of MTEs on word-of-mouth and revisit intentions. This study identified key memorable experiences of visitors in Xitou Nature Education Area (XNEA), Taiwan (R.O.C.), and examined the relevant relationships among MTEs and behavioral intentions. The results revealed that both refreshment and involvement experiences received the highest scores from the respondents, whereas perceived local culture received the lowest score. Refreshment, local culture, and involvement positively influenced the word-of-mouth intention of visitors. Additionally, hedonism, local culture, and involvement significantly positively influenced the revisit intention of visitors. This study provides additional insights into MTEs in nature-based tourism. The study results underline the importance of MTEs in forest recreation destinations that can encourage more word-of-mouth and revisit intentions of tourists.

Perceived Customer Value

Purpose This paper aims to propose an approach to broaden the focus of a low-fidelity prototype (i.e. mock-up) to enable user experimentation in a real environment at the early stages of the product development process. The functionality approaching a real solution enables customers to experience the key functionality, and therefore, the perceived customer value of the new product idea before major investments in the development. Design/methodology/approach The study is based on an interventionist case study in a manufacturing company. The researchers were involved in the development of two new products and analysing the potential process and cost implications. Findings Mock-ups enable the preliminary measurement of cost and value implications of a new product at the early stages of the development process. This holds significant potential for advancing development practices and reducing the uncertainties present in such processes. Thus, the business case at the early stage of the development process can be argued with “user-experienced” cost information and, therefore, also “perceived” customer value. Practical implications The use of mock-ups to gain customer feedback is well aligned with the fail-fast mentality emphasised in the contemporary start-up scene, but this study also encourages developers/practitioners from mature industries to use mock-ups to assess perceived customer value. Originality/value The originality of the paper lies in broadening the focus of mock-ups to enable user experimentation in a real environment at the early stages of the development process.
