- Reconnoitring how structural design in the context of industrial design engineering evolves
by Eliab Opiyo
Abstract: This paper presents the findings of a study conducted to explore how structural design unfolds in industrial design engineering processes. The study focused specifically on structural design of engineering consumer products with physical constructions. The investigation conducted included questionnaire surveys, interviews, and observations. A total of three hundred and fifty eighty subjects participated in two rounds of the investigation. The study uncovered how structural design in the context of industrial design engineering progresses in practical settings and provided clues on how a formal structural design process model should be like. One of the main observations was that the subjects chose and strictly followed and adhered to their own preferred structured order of execution of structural design activities. Another cardinal observation was that, unlike analysis and concepts development activities, the structural design activities of materials selection, engineering analysis, and process selection were executed recursively and oftentimes concurrently by most of the subjects. Based on these observations and upon an analysis of the information gathered, a linear-recursive-linear (LRL) scheme for tracking, managing, and coordinating the execution of structural design activities has been formulated. Separate studies are, however, needed to investigate the validity, efficacy, and the applicability of this scheme.

- A road map for implementing lean and agile techniques in SMEs product development teams
by Marco Leite, A. J. Baptista, A. M. R. Ribeiro
Abstract: The aim of this research paper is to formulate a road map for implementation of lean techniques within SMEs product development (PD) teams, identifying barriers to change and explaining possible drivers for successful implementation. The research methodology necessary to develop the road map - the IPID cycle - is a combination of different approaches. It combines a literature review, an initial quantitative study with questionnaires, informal interviews and direct observation of companies practices of five different manufacturing companies organized in a consortium. Like any other case study methodology, it suffers from generalization issues, but we expect that the proposed road map is applicable whenever managers need to introduce changes inside their PD teams.
Also, we found that a consortium arrangement can be highly positive to the implementation of the proposed road map. Finally, we found that the application of the road map to SMEs PD teams is somewhat different from big companies implementations and discuss the observed particularities of these findings.

- An Action Research Approach to Early Concept Iteration in a Design Consultancy
by Tom Page
Abstract: This paper investigates early stage concept iteration with a design consultancy environment. An empirical and journal-based literature review was used to develop a theoretical framework to advance research into the concept of design Iterations within the consultancy environment. This work takes an action research approach to concept iteration in product form design and developmentrnat the early stage of the design process. Budgetary constraints, time management and client expectation were identified as determining factors in driving early concept iteration in the design consultancy environment. The findings of this action research work may be of use to design consultants and design management.

- An integration model for innovative products in Korea and China: Bio-based smart clothing
by Mijin Noh, Hyunhee Park
Abstract: In order to analyze users acceptance of an innovative product in the information age, this study investigates the relationships among perceived ease of use, usefulness, enjoyment, and purchase intention of smart clothing based on bio-signal. This study considers the fashion innovation and technology innovation to understand potential users characteristics of innovative products. To achieve objectives of this study, we carry out the survey targeting reading groups, and providing them with pictures of biomedical smart clothes. Perceived ease of use and benefit had a positive effect on the purchase intention in Korea, but did not have an effect on the purchase intention in China. The results of the difference analysis shows that the fashion innovation perceiving the Chinese customers had a greater impact the perceived ease of use and usefulness than the Korea customers. This study provides various insights on the market for innovative products, suggesting that our results may be useful to both companies and researchers.
