- Resonance Testing: An Industry Approach for Experiential Concept Evaluation
by Lassi A Liikkanen
Abstract: This paper describes a professional practice in user-centered product concept design that is embedded in a method called resonance testing. It is a nimble method used and developed in industry to ensure that desired properties of design are communicated to the user through the design. It tests product concepts for emotional and functional design attributes such as personal identification and meaningfulness. In resonance testing, the users of a specified segment experience design artifacts of variable abstraction levels to see how they perceive the qualities of a concept and how it matches their preferences. We find that literature lacks both effective user feedback solutions for early product decisions and discussion of the known challenges for doing that. The paper describes how resonance testing generates qualitative insights, builds confidence in new concepts, and helps designers to develop the right concept for further development. We present two cases studies of utilizing this method.

- CONTEXT MANAGEMENT IN COLLABORATIVE DECISION MAKING IN COMPLEX DESIGN PROJECTS
by Marija Jankovic, Julie Stal Le Cardinal, Jean-Claude Bocquet
Abstract: The notion of context seems to be a growing subject in the engineering sciences. Several studies have pointed out the necessity to address the contextual limitations in collaborative design projects. It has been identified as one of the major factors that contribute to inadequate knowledge reuse in design projects. Nevertheless, the definition of the context depends on the subject and the field of application. In this paper, we point out different definitions of the context in artificial intelligence, engineering and cognitive sciences. In this research study we present a proposition for context modelling representing only one part of collaborative decision-making support. The research study presented in this paper is a result of collaboration with one of the French car manufacturers. Within the conceptual model of collaborative decision-making, we propose to integrate the information concerning three different contexts: decision, project and enterprise context. The aim of this model is to help and support the project team in project management.

- Success Factors of Product Concepts for Convergence Products in the Telecommunications, Internet, Media, and Entertainment Industries
by Daniel Holle, Stefan Huesig, Michael Dowling, Nikolaus Mohr
Abstract: The convergence of the Telecom, Internet, Media and Entertainment (T.I.M.E.) markets has been taking place for decades, but many convergence products designed and marketed by experienced corporations have failed. We propose that the problems associated with newly developed convergence products are often the result of poorly defined product concepts. Specific research on product development and product concepts that is focused on convergence in these industries has so far been largely lacking. In this empirical study, we derived 18 hypotheses on the success factors of convergence products based on information attained from a literature review and interviews with industry experts. We tested these hypotheses using a large scale survey conducted in Germany, Austria, and Switzerland. We identified 13 success factors as being relevant for product market success, seven of them being of particular importance. The findings expand on the existing findings on success factors for product development as well as convergence research and practice.

- Utilising Computerised Tools and IT in New Product Development to Constitute Firms Financial Performance and the Impact of R&D Intensity
by Sadami Suzuki, Takao Enkawa, Tanyanuparb Anantana
Abstract: By using New Product Development Scorecard (NPDSC) as a data collecting tool, field surveys were conducted for 396 participating firms in 14 Japanese manufacturing industries. According to the analyses results, two elements of Development strategy and organisation and Development production technology are identified as enabling f actors for the complement of utilising tools and IT in NPD. It is also suggested that in order to make a positive impact on financial performance, tools and IT should have to be incorporated with these enabling factors. In addition, it is found that level of utilisation capability of tools and IT is significantly higher in high R&D intensity group compared to the low one. And level of R&D intensity affects the implementation methods of tools and IT for NPD and the contribution to financial performance, as well. Consequently, useful managerial implications are provided in this work.

- Predicting the competitive advantage of design projects to dynamically support decisions in product development
by Yuri Borgianni, Federico Rotini
Abstract: Many product development initiatives are planned on the basis of the supposed capability to generate customer satisfaction. However, market and technology conditions can undergo several transformation during the execution of product innovation projects and jeopardize the basic assumptions taken at the beginning of the design cycle. Among the changing factors, the observed alternation of radical and incremental transformations of product architectures is viable to influence the success chances of new products. Such an aspect is taken into account in the decision support tool described in the paper, which can be employed to select the most beneficial alternatives in a set of different product ideas.

- The Influence of Innovativeness and Price Sensitivity on Purchase Intention: Comparison of the Chinese and Korean Consumers Response
by Hyun Hee Park, Pauline Sullivan, Mi Jin Noh
Abstract: This study explores difference in the influence of innovativeness and price sensitivity on purchase intentions, among consumers in China and Korea, focusing on bio-signal smart clothing. Questionnaires were administered to 227 Chinese and 222 Korean consumers. Results are summarized as follows. First, fashion innovativeness and technology innovativeness negatively affected price sensitivity, both in China and Korea. Second, technology innovativeness positively affected purchase intentions in Korea, while fashion innovativeness positively affected purchase intentions in China. Third, price sensitivity negatively affected purchase intentions in both China and Korea. Fourth, no difference existed in the magnitude of the effect of fashion innovativeness on price sensitivity among China and Korea consumers, but technology innovativeness had greater effect on price sensitivity on the Chinese consumers. Fifth, fashion innovativeness had a greater effect on Chinese consumers purchase intentions, while technology innovativeness had a greater effect on Korean consumers purchase intentions.

- INVESTIGATING THE EFFECT OF VARIABILITY IN PRODUCT DEVELOPMENT LIFE CYCLE
by Riham Khalil, David Stockton, Mohamed Alkaabi, Lawrence Manyonge
Abstract: Projects have evidently become the core activity in most companies and organisations where they are investing significant amount of resources in different types of projects as building new services, process improvement, etc. This research has focused on service sector in attempt to improve project management planning and control activities. This paper investigates the planning and control of software development projects by analysed existing software development models, identifying best practices from these models so as to develop a model for improving software development tasks. The research extends the existing planning and control approaches by considering uncertainty in customer requirements, resource flexibility and risks level variability. In considering these issues, the research has adopted lean principles for planning and control software development projects. A novel approach introduced within this research through the integration of simulation modelling techniques with Taguchi analysis to investigate what if project scenarios. Such scenarios reflect the different combinations of the factors affecting project completion time and deliverables. In addition, this paper adopts the concept of Quality Function Deployment (QFD) to develop an automated Operations Project Management Deployment (OPMD) model. The model acts as an iterative manner uses what if scenario performance outputs to identify constraints that may affect the completion of a certain task or phase. Any changes made during the project phases will then automatically update the performance metrics for each software development phases. In addition, optimisation routines have been developed that can be used to provide management response and to react to the different levels of uncertainty.

- The House of Concepts as a matrix-based problem-solving method in conceptual design
by Stefan Punz, Peter Hehenberger
Abstract: As most of the key properties of a product are determined by its design concept, customer orientation must be ensured very early in the conceptual design phase. Hierarchical concept development can help to reduce the complexity of this strategically significant task. This paper examines the process of hierarchical concept design by means of the House of Concepts (HoC) approach, which was conceived specifically to support customer-oriented concept development. This approach, which builds upon Quality Function Deployment (QFD), is compact, illustrative, enhances comprehensibility and can be considered both a method and a guiding principle. Supporting the creation of solution concepts by analysing the dependencies between requirements, functions, structure and properties with matrix-based methods allows verifying the suitable product concepts. The HoC method promotes customer orientation, especially during conceptual design, and supports systematic concept development at different levels of abstraction. Thus, it enables step-by-step development of product concepts and helps to reduce the complexity of this important engineering task. The HoC approach can be used to ensure customer orientation in the development of product concepts, which leads to an increase in effectiveness in product development.
