- 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.
Keywords: innovativeness, price sensitivity, cross-cultural, information technology, smart Clothing
- 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.

- Next practice, not best practice: Using virtual worlds in new product development in the automotive industry
by Julia Daecke, Dodo zu Knyphausen-Aufseß, lars Schweizer
Abstract: Involving customers in the development of new products development is crucial to market success. However, many companies, especially within the technology-oriented automotive industry, fail to do so. In this article, we examine how web-based virtual worlds offer fresh perspectives for integrating customers into product development. We argue that companies must look to "next practice, not best practice" if they hope to outperform the market. We also investigate the steps involved in such projects, and the factors that make them possible. We conducted interviews with managers from three leading car manufacturersAudi AG, BMW Group and Daimler AGand experts from industry-related research institutes and service companies. Our findings demonstrate that virtual worlds support more efficient and effective new product development projects, especially in their early and late phases.

- Fuzzy front end activities in new product development process: A comparative study of Japanese and Korean projects
by Ruslan Mammetseyidov, Akio Nagahira
Abstract: The aim of this study was to reveal both direct and indirect impacts of fuzzy front end activities in Japanese and Korean manufacturing firms during corresponding successful periods of each country. The analysis of 540 Japanese and 293 Korean new product development projects was carried out using structural equation modeling.
The results suggest that Korean firms tended to keep more close attention on reduction of market uncertainty activities compared to Japanese firms. In addition, initial planning activities are strongly significant in minimizing changes that could lead to revision of a whole project, but not on minimizing changes that are necessary to adapt to requirements determined by dynamic business environmental changes.
