Shared knowledge and product design glitches in integrated product development

Product development processes based on the joint collaboration of the cross-functional team, suppliers, and customers can minimize project glitches. Glitches in the product development project can cause project cost over-runs and delay a project past when first mover advantages are possible. While previous theoretical work has suggested a negative relationship between shared knowledge and product development glitches, empirical studies have not identified how different types of shared knowledge are associated with each other and the design glitches. This study proposes a model of the relationship between specific types of shared knowledge and design glitches in integrated product development (IPD) projects. We test our model using a sample of 191 projects from the automotive industry in the United States. The major findings were that: (1) shared knowledge of the development process can be built by improving a team's shared knowledge of customers, suppliers, and internal capabilities, (2) shared knowledge of the development process for a project reduces product design glitches, and (3) reduced product design glitches improve product development time, cost, and customer satisfaction.     

User-oriented design for the optimal combination on product design

This paper presents a new approach of user-oriented design for transforming users’ perception into product elements design. An experimental study on mobile phones is conducted to examine how product form and product color affect product image individually and as a whole. The concept of Kansei Engineering is used to extract the experimental samples as a data base for Quantitative Theory Type I and neural networks (NNs). The result of numerical analysis suggests that mobile phone makers need to provide various product colors to attract users, in addition to product forms. This paper demonstrates the advantage of using NNs for determining the optimal combination of product form and product color, particularly if the product into design elements. Based on the analysis of NNs, we can use 72 representative product colors of each mobile phone to develop a product color data base consisting of 16777216 (=256×256×256, True-Color model) colors with the associated product image. The design data base provides useful insights to save any amount of money and time for the new product development. The product designers can input a product image to work out an adequate color on a mobile phone. Furthermore, the design data base can be used, in conjunction with computer-aided design system or virtual reality technology, to build a 3D model for facilitating the design process of mobile phones. Although, the mobile phones are chosen as the object of the experimental study, this approach can be applied to other products with various design elements.     

Evaluating product and process design changes with warranty data

This paper suggests evaluating field performance by analyzing hazard plots of the random variable time to first warranty claim. This approach corrects biases that arise when a single member contributes many repairs to the repair population and allows comparing the empirical lifetime distribution with the parametric model assumed at product design (e.g., Exponential or Weibull). Using automobile warranty data we demonstrate how using too broad a scope can mitigate changes in field performance by aggregating improving and degrading components. When comparing warranty performance across model years, the analyst should adjust the hazard plots to reflect common field service time.     

Coordination at different stages of the product design process

This paper addresses the following question: how does the coordination challenge faced by managers change over the life of time bound projects such as product design. We use coordination structure, an approach to modeling organizational situations that highlights concurrent responsibility interdependencies rather than the more traditional task interdependencies. We explain coordination structure and use it to capture the responsibility interdependencies in a sample of complex system design projects drawn from two different organizations. We use this data: to illustrate the differences possible in the responsibility interdependencies that can exist within design projects from different organizations and at different project key points; to identify a set of four basic modules, or groupings, of responsibility interdependencies useful for modeling design organizations; and to generate a set of testable hypotheses on how the coordination challenge faced by project managers can vary between organizations and over project key points.     

Integrating the Kano model into a robust design approach to enhance customer satisfaction with product design

The aesthetic qualities of products are critical factors in achieving higher customer satisfaction. This study presents a robust design approach incorporating the Kano model to obtain the optimal combination of design form elements. This can effectively enhance customer satisfaction and aesthetic product qualities with multiple-criteria characteristics. The Kano model is used to better understand the relationship between performance criteria and customer satisfaction, and to resolve trade-off dilemma in multiple-criteria optimization by identifying the key criteria in customer satisfaction. The robust design approach combines grey relational analysis with the Taguchi method to optimize subjective quality with multiple-criteria characteristics. This simultaneously yields the optimal aesthetic performance and reduces the variations in customer evaluations. Based on Kano model analysis, a weight adjustment process determines the weight of each product criterion for achieving the desired customer satisfaction performance. This process guides the prioritizing of multiple criteria, leading to higher customer satisfaction. A mobile phone design experiment was conducted to verify the benefits of using the proposed integrative approach. Results show that the generated optimal mobile phone design can effectively enhance overall aesthetic performance and customer satisfaction. Although mobile phone designs are the examples of this study, the proposed method may be further used as a universal robust design approach for enhancing customer satisfaction and product quality with multiple-criteria characteristics.

Role of cultural inspiration with different types in cultural product design activities

Inspiration plays an important role in the design activities and design education. This paper describes “ancient cultural artefacts” as “cultural inspiration”, consisting of two types called “cultural-pictorial inspiration” (CPI) and “cultural-textual inspiration” (CTI). This study aims to test the important role of cultural inspiration with different types in cultural product design activities. Through an exploratory experiment, design students were asked to extract cultural features from ancient cultural artefacts and generate new “culturally-oriented products”. Two experts statistically analyzed the categories and quantities of cultural features, and then evaluated the creativity (originality and practicality) of design outcomes. Results show that students who worked with CTI create more creative outcomes than students who worked with CPI. It was also found that cultural features generation affect the originality of design outcomes.

The locating of emotion within a creative, learning and product orientated design and technology experience: person, process, product

Within this paper, a conceptualised triadic schema is hypothesised for locating emotion within a creative, learning and product orientated Design and Technology experience. The research is based upon an extensive literature review that has been synthesised and juxtaposed with the broad aspirational aims of the subject. The schema, based upon abductive reasoning and grounded theory, ultimately conceptualises the overarching theme of emotion within a creative, learning and product orientated Design and Technology experience within the Primary and Secondary stages of England’s education system. The triadic schema offers an additional opportunity in meta-theorising how the broad aspirational aims of the subject, as outlined in the English national curriculum statement of importance for Design and Technology, can be achieved through recognising the powerful overarching concept of emotion within three emerging domains: Person, Process and Product. The central tenet of this paper is the recognition of emotion within a triadic schema for meta-theorising the place of emotion within a creative, learning and product orientated Design and Technology experience. David Spendlove was previously a senior teacher in secondary education before moving into Higher Education and is now the subject leader for Design and Technology at the University of Manchester. He co-edits both Design and Technology Education: An international Journal and the DATA international research conference proceedings. He is a director of the Design and Technology Association and his research interests are broadly based around learning, pedagogy, creativity, emotion and gender.     

Coordinating dispersed product development processes: A contingency perspective of project design and modelling

Managing worldwide supply pipeline operations concerns coordination and control of every step of the chain process starting from raw material sourcing, production, finally to distribution of market-specific items in retail places, all the way from product value inception and engineering, through manufacturing design, to the worldwide logistic planning. From systems perspectives, their relationships and interactions determine the overall performance. Coordinating such systems is very human-inclusive, characterised by abstract, ill-structured information interchange among well-partitioned expert groups. In this paper we documented the experience and implications of managing and modelling product development activities from a contingent perspective of interdependence. In our investigations amongst six international fashion corporations, crucial activity tasks in different countries were analyzed and evaluated within the context of launching schedule-driven fashion products. At the outset, we present the problem context, the issues arising from coordinating product development systems, and the approach we use to deal with the issues, i.e. modelling and manipulating the process interaction. We put forth a dependency-based process performance simulation, the related approach of data capture and the attribute constructs to represent the interactivity relationship. Finally, we discuss the computation process and evaluation strategy, which is indeed inspired by today's simulation-based optimization concepts. An effective GA heuristics is duly implemented.     

Interactive effects of environmental experience and innovative cognitive style on student creativity in product design

Environmental experience can enhance the ideas of design students. Thus, this type of experience may interfere with the influence of design students’ cognitive style on creativity. The aim of this study was to examine the influence of environmental experience on the relationship between innovative cognitive style and industrial design students’ creative outcomes. The environmental experience was measured according to the total scores of the five components of sense, feel, think, act, and relate on the basis of Schmitt’s strategic experience modules. The cognitive styles were measured using Kirton’s adaption–innovation inventory, and creative works were assessed through the consensus assessment technique, which was employed by three experts. Through a field experiment and survey investigation, the analysis indicated that innovative cognitive style significantly and positively influenced creativity, but this only occurred when student was accompanied with a low degree of environmental experience (i.e., a student had a low score for environmental experience); as the student attained a high degree of environmental experience, the influence of innovative cognitive style on creativity became weakened. The experiential media suggested that the natural elements, cultural history, group travel, and narrator effectively diversified the experiences of the students and enhanced creative thinking. This paper suggests providing increased stimulation of environmental experience prior to instructing design students to engage in creative activity. Environmental experience can benefit students by enhancing their creativity.     

Customer interactivity and new product performance: Moderating effects of product newness and product embeddedness

Understanding customer needs which drive significant product innovation is particularly challenging for new product development (NPD) organizations. Research has addressed how organizations benefit from interacting with customers, but more conceptualization is needed into the dimensions of the customer interaction process. In a business-to-business (B2B) setting, customer interactivity is conceptualized as a multi-dimensional construct consisting of bidirectional communications, participation, and joint problem solving during NPD projects. Drawing upon organizational information processing theory, customer interactivity is hypothesized to be positively related to customer information quality when developing highly innovative products, but not when developing modifications or extensions of existing products. Another condition affecting this relationship studied is the embeddedness of the new product in the customer's business environment. Customer interactivity is hypothesized to be positively related to information quality for highly embedded product, but not for low embedded product. Results from a sample of NPD organizations in several B2B industries support these hypotheses. The study contributes to the marketing literature and practice by identifying important dimensions of the customer interaction process which lead to more proactive organizations, and identifying two moderating conditions of the customer interactivity and NPD performance relationship.     

The abilities of understanding spatial relations,spatial orientation,and spatial visualization affect 3D product design performance: using carton box design as an example

Three-dimensional (3D) product design is an essential ability that students of subjects related to product design must acquire. The factors that affect designers’ performance in 3D design are numerous, one of which is spatial abilities. Studies have reported that spatial abilities can be used to effectively predict people’s performance in conducting complex operations. Nevertheless, few studies have explored the relationship between spatial abilities and designers’ performance in 3D product design. Spatial ability is a type of mental ability and comprises numerous factors. Carton box design is a typical type of standardized 3D product design, in which designers’ performance is affected by the spatial abilities they possess. The most crucial factor among these abilities is the space conversion ability, which is the ability to convert two-dimensional (2D) surface developments into 3D perspective views and convert 3D carton boxes into 2D plans. These operations require an in-depth perception of objects, an understanding of the relative spatial relations among objects, and spatial visualization. In this study, carton box design was used as an example to investigate, using structural equation modeling, the effects that the ability to understand spatial relations, spatial orientation, and spatial visualization have on designers’ performance in 3D product design. The results indicated that all three spatial abilities (i.e., understanding spatial relations, spatial orientation, and spatial visualization) directly influence designers’ performance in carton box design. Therefore, spatial abilities are vital factors affecting designers’ performance in 3D product design.     

Tactical product decisions

The focus of this article is a discussion of both how and when to make tactical product decisions for existing products. Although the literature refers to these decisions in the context of strategic planning, the author considers that it is inadequate in explaining how and when these decisions should be arrived at relative to tactical planning. A range of criteria for tactical decisions is proposed.

R&D and product obsolescence

Claims of planned obsolescence have often been made by various consumer groups. Bulow (1986) examined a monopolist's choice of product durability and found that firms who sell their products tend to choose lower durability levels than firms that rent. We argue that the speed of new product development may be a more appropriate proxy for obsolescence than is durability. Reformulating Bulow's model in terms of R&D choice rather than durability choice, we find that sales firms engage in higher levels of R&D than do rental firms. Additionally, we provide an empirical example using data from the copier and computer industries which also suggests a strong positive relationship between the R&D intensity of a firm and the proportion of output sold versus rented.
