What is the function of a figurine? Can the repertory grid technique tell?

Teaching design and product development at upper secondary school level in Sweden is a matter of interdisciplinary considerations. Education in product development, at this level, prepares students for further studies and career in engineering or industrial design. Knowledge of artefacts is an important element in the education. In coherence with the visual and rhetorical strategies characterising the knowledge field, students learn how to develop an idea to a final product. In this study twelve engineers and industrial designers, professionals representing the knowledge field of product development are studied regarding their interpretations of eight pre-selected artefacts. Data is collected and analysed using repertory grid technique. The aim of the study is to examine whether/what we can learn from the informants’ experiences and knowledge that is relevant to education in design and product development at upper secondary school level. Findings show that four of the artefacts appear to be carriers of attributes that reveal the interviewees’ definitions of the artefacts’ functional nature. From these findings it is shown that the interviewees’ definitions of concepts concerning aesthetics/decoration and function can be seen as cultural expressions. How the repertory grid technique is used in this particular study is thoroughly described and the results relevance for education is discussed.     

Redesigning Product Lines with Conjoint Analysis: How Sunbeam Does It

Sunbeam Appliance Company, faced with the task of redesigning its lines of small appliances, developed a procedure that couples consumers' evaluations of possible new designs with a marketing research technique—conjoint analysis. In this article, Albert Page and Harold Rosenbaum describe Sunbeam's redesign of its food processor product line. They report detailed information, including key design attributes, alternative product designs, market segments, and competitive positions, and describe the use of a simulation model that predicts the market share of alternative product line configurations before they are even developed or introduced into the market. The procedure provides product line managers with a powerful tool to assist them in redesigning their lines.     

Managing Design in Small High-Growth Companies

Cost-cutting measures may keep investors happy, but such belt-tightening does little for a company's long-term growth. In an era of ever-shrinking product life cycles, effective product design skills are essential to any company's ongoing vitality. To remain competitive, even the largest manufacturers must learn to replicate the entrepreneurial drive and innovativeness that characterize small, high-growth firms. To foster a better understanding of the product design skills of small, high-growth firms, Peter Dickson, Wendy Schneier, Peter Lawrence, and Renee Hytry describe the results of a survey of CEOs from companies that have been included in the Inc. 100 or Inc. 500 lists. On average, 50% of the sales for these companies came from new products launched during the past 3 years. The survey addresses three fundamental questions. First, which aspects of design management do the CEOs of small, high-growth firms believe they manage well, and which give them difficulty? Second, to what extent are the CEOs involved in design decisions? Finally, how important is good product design to these firms? The respondents face the most difficulty in making the transition from sequential to concurrent engineering and design. Many cite a need for improved management of such skills as design for manufacturability, involvement of suppliers in the design process, estimation of costs during the design process, and the use of computer-aided design tools during the design process. In contrast to these engineering-related aspects of product design, the respondents are more confident in their ability to handle such marketing-related tasks as generating new design ideas and involving customers in the design process. The survey results indicate that CEOs of small, high-growth firms are deeply involved in design decisions. In over half the companies surveyed, CEOs indicated they had primary responsibility for design decisions. Most respondents also reported increasing their investment in design, with approximately 75% increasing their investment in product/service design over the past 3 years and almost 50% increasing their investment in packaging design. CEOs of Inc. 100 and Inc. 500 firms clearly recognize the importance of design. Approximately 70% of the respondents believe that design issues will be of increasing importance for U.S. firms' competitiveness in the coming years, and the majority feel it is important that their managers be knowledgeable about design. Approximately 75% of the CEOs believe that adopting new, fast-track approaches to new product design would improve their firms' competitiveness.     

Neo‐Rawlsian Fringes: A New Approach to Market Segmentation and New Product Development*

Prior research into the link between new product development and market segmentation has focused on two main approaches: (1) design, segment, and do limited competitive evaluation; and (2) segment first, design second. This paper proposes a third approach, which is to simultaneously design, perform segmentation according to benefit and to evaluate against competitive designs. This research uses a benefit segmentation technique based on conjoint analysis (or other techniques that relate product attributes to consumer utility) in which the segments emerge simultaneously with the design based on certain design principles or “strategies.” Herein a method is proposed to narrow down the many possible feasible designs (combinations of attributes) to a finite set and to examine the appeal of each design. Five distinct design strategies are proposed for modeling and studying competitive reaction. These include “traditional” ones such as differentiation and new ones whose fringe customers have high utility. The paper shows that these five strategies are adequate for modeling competitive reaction using simulation. Another contribution of the paper is the way competitive reaction is modeled. In generating and evaluating a design the desire herein is also to assess the defensibility of the design and include it in the evaluation criteria. These issues are addressed by decomposing the solution procedure into two phases. In the first phase, different optimal designs are created based on predefined product development strategies. In the second, these optimal designs are compared against one another with regard to market share and potential to secure market leadership. This work shows that the nature of competition as well as the variability of customer preferences are critical to how a strategy performs. This process uncovers a surprisingly robust design strategy—developing attributes such that a “lower fringe” is most satisfied—that even achieves market dominance under certain conditions. This methodology is also applied to partworth data on refrigerators, which provides a concrete example of the concepts and demonstrates results consistent with the propositions developed earlier in the paper.     

A path model of factors affecting secondary school students’ technological literacy

Technological literacy defines a competitive vision for technology education. Working together with competitive supremacy, technological literacy shapes the actions of technology educators. Rationalised by the dictates of industry, technological literacy was constructed as a product of the marketplace. There are many models that visualise different dimensions of technological literacy, but clear empirical evidence on how these interact is still lacking. A measurement method that comprehensively evaluates technological literacy is missing. Insights into the stem structure and interaction of technological literacy dimensions could be useful for technology education curriculum design and its implementation. In this study, the multifaceted nature of technological literacy was measured using a new assessment method, and dimensions of secondary school students’ technological literacy were empirically investigated. A total of 403 students participated in the quasi-experimental research design. The treatment group consisted of 121 students taught optional subjects relating to technology education. The control group consisted of 282 students. Results from variance analysis showed that optional technology subjects enhance technological literacy, especially students’ technological capacity where a large effect size (η ²  = 0.14) was noted. Results from a path analysis revealed critical thinking and decision-making as the most important dimensions of technological literacy while the predictor of active participation in out-of-school technical activities and technology homework was a key independent influencing factor. A large effect size (R ²  = 0.4) for career path orientation predictors was detected. Technological capacity was revealed as a decisive predictor for a career path in vocational education and technical high school.     

Examining design cognition coding schemes for P-12 engineering/technology education

Cultivating students’ design abilities can be highly beneficial for the learning of science, technology, engineering, and mathematics (STEM) concepts, and development of higher-order thinking capabilities (National Academy of Engineering and National Research Council in STEM integration in k-12 education: status, prospects, and an agenda for research, The National Academies Press, Washington, 2014). Therefore, examining students’ strategies, how they distribute their cognitive effort, and confront STEM concepts during design experiences, can help educators identify effective and developmentally appropriate methods for teaching and scaffolding design activities for students (National Research Council in standards for k-12 engineering education? The National Academies Press, Washington, 2010). Yet, educational researchers have only recently begun examining students’ engineering design cognition at the P-12 level, despite reports such as Standards for K-12 Engineering Education? (National Research Council 2010) designating this area of research as lackluster. Of the recent studies that have investigated engineering design cognition at the P-12 level, the primary method of investigation has been verbal protocol analysis using a think-aloud method (Grubbs in further characterization of high school pre- and non-engineering students’ cognitive activity during engineering design, 2016). This methodology captures participants’ verbalization of their thought process as they solve a design challenge. Analysis is typically conducted by applying a pre-determined coding scheme, or one that emerges, to determine the distribution of a group’s or an individual’s cognition. Consequently, researchers have employed a variety of coding schemes to examine and describe students’ design cognition. Given the steady increase of explorations into connections between P-12 engineering design cognition and development of student cognitive competencies, it becomes increasingly important to understand and choose the most appropriate coding schemes available, as each has its own intent and characteristics. Therefore, this article presents an examination of recent P-12 design cognition coding schemes with the purpose of providing a background for selecting and applying a scheme for a specific outcome, which can better enable the synthesis and comparison of findings across studies. Ultimately, the aim is to aid others in choosing an appropriate coding scheme, with cognizance of research analysis intent and characteristics of research design, while improving the intentional scaffolding and support of design challenges.     

Factors influencing student success on open-ended design problems

Open-ended design problems have become an important component in our educational landscape (Grubbs and Strimel in J STEM Teach Educ 50(1):77–90, 2015; Jonassen et al. in J Eng Educ 95:139–151, 2006; National Research Council in Education for life and work: developing transferable knowledge and skills in the 21st Century, National Academies Press, Washington, 2012; Strimel in Technol Eng Teach 73(7):8–18, 2014a). The ability of students to confront open-ended problem scenarios, think creatively, and produce novel designs have all been lauded as necessary skills for today’s twenty first century learners (Partnership for 21st Century Skills in P21 framework definitions, Author, Washington, 2016). This emphasis on open-ended design problems in problem-based learning scenarios has been tied to workforce and higher education preparation for students (National Academy of Engineering and National Research Council in STEM integration in K–12 education: status, prospects, and an agenda for research, National Academies Press, Washington, 2014; National Research Council in Engineering in K–12 education: understanding the status and improving the prospects, National Academies Press, Washington, 2009; Strimel in Technol Eng Teach 73(5):16–24, 2014b). However, little research has been conducted to identify the impact of potentially-influential factors on student success in such open-ended design scenarios. Therefore, the researchers examined data from 706 middle school students, working in small groups, as they completed an open-ended design challenge to determine the relationships between a variety of potentially-influential factors and student performance, as measured through adaptive comparative judgment. The analysis of the data revealed several relationships, significant and not significant, between identified variables and student success on open-ended design challenges.     

New Industrial Product Design and Evaluation Using Multiattribute Value Analysis

Increasingly, the design of successful new industrial products is related to careful market assessment. Traditionally, managers and researchers have studied their markets by examining a small number of product attributes that are common across a range of informed respondents. In many ways, these techniques fail to meet the challenges posed by today's often heterogeneous, highly competitive, fast moving industrial markets. Ralph Keeney and Gary Lilien introduce us to a technique they call multiattribute value analysis, both describing the procedure and describing a comprehensive example. Their approach introduces considerable flexibility to the process of market assessment. Technically, it permits the evaluation of many more attributes, value tradeoffs, and synergies among attributes than do more traditional methods. In addition, it permits nonlinear evaluation functions that may be idiosyncratic to the individual. Practically, their approach, illustrated with a detailed case application, is shown to have significant potential for aiding product design decisions.     

Modified Stage‐Gate® Regimes in New Product Development*

The purpose of this research was to explore the nature of the Stage‐Gate^®process in the context of innovative projects that not only vary in new product technology (i.e., radical versus incremental technology) but that also involve significant new product development technology (i.e., new virtual teaming hardware‐software systems). Results indicate that firms modify their formal development regimes to improve the efficiency of this process while not significantly sacrificing product novelty (i.e., the degree to which new technology is incorporated in the new offering). Four hypotheses were developed and probed using 72 automotive engineering managers involved in supervision of the new product development process. There was substantial evidence to creatively replicate results from previous benchmarking studies; for example, 48.6% of respondents say their companies used a traditional Stage‐Gate^®process, and 60% of these new products were considered to be a commercial success. About a third of respondents said their companies are now using a modified Stage‐Gate^®process for new product development. Auto companies that have modified their Stage‐Gate^®procedures are also significantly more likely to report (1) use of virtual teams; (2) adoption of collaborative and virtual new product development software supporting tools; (3) having formalized strategies in place specifically to guide the new product development process; and (4) having adopted structured processes used to guide the new product development process. It was found that the most significant difference in use of phases or gates in the new product development process with radical new technology occurs when informal and formal phasing processes are compared, with normal Stage‐Gate^®usage scoring highest for technology departures in new products. Modified Stage‐Gate^®had a significant, indirect impact on organizational effectiveness. These findings, taken together, suggest companies optimize trade‐offs between cost and quality after they graduate from more typical stage‐process management to modified regimes. Implications for future research and management of this challenging process are discussed. In general, it was found that the long‐standing goal of 50% reduction in product development time without sacrificing other development goals (e.g., quality, novelty) is finally within practical reach of many firms. Innovative firms are not just those with new products but also those that can modify their formal development process to accelerate change.     

A pedagogic approach to enhance creative <Emphasis Type="Italic">Ideation</Emphasis> in classroom practice

The real intent for technology education is to prepare young people so that they may fully participate and function in human society. To achieve this aim, learners are guided towards the development of attributes that include perceptive, critical, creative and informed decision making. Although effective teaching strives to inspire the creative spark in every learner, there is little guidance to inform actual classroom practice. The selection of strategies and implementation methods that engender creative responses in students, is usually left to an individual teacher’s interpretation. A working knowledge of design processing provides a most advantageous methodology to guide teaching and learning as students develop ways “of knowing through thinking and doing,” Sharma and Poole (Des Manag Inst 20(4):64–74, 2010) within classroom design and technological practice. This article looks at the broad stage of Ideation in creative design practice, where designers instigate and generate ideas within their own practice. Insight and transferable skills are observed to inform classroom practice. One event from the ideation stage of design practice processing is selected to enhance student visual communication skills. A pedagogic approach is then shared to inform the implimentation of a teaching and learning strategy that has been trialled with design (aged from 12 to 18 years) and Initial Teacher Education adult students.     

Being Innovative While Being Green: An Experimental Inquiry into How Consumers Respond to Eco‐Innovative Product Designs

Eco‐innovations are an effective way for companies to strategically align themselves with customers’ growing environmental concerns. Despite their crucial role, scant research has focused on eco‐innovative product designs. Drawing from the sustainability and innovation literature, this article proposes that in the design of an eco‐innovation, its degree of innovativeness, level of eco‐friendliness, and detachability significantly affect consumers' adoption intentions. This article develops various conceptual models tested through three independent online experiments with U.S. consumers. The findings support the hypotheses and provide useful insights into the underlying mechanisms of how and why consumers respond to eco‐innovative product designs across various high‐tech product categories. Specifically, the results show (1) a positive effect of innovativeness degrees of eco‐innovative attributes on consumers' perceptions of product eco‐friendliness and on their adoption intentions as well as a significant moderating role of consumers' need for cognition (Study 1); (2) a positive influence of eco‐friendliness levels of eco‐innovative attributes on consumer adoption intentions in the case of high‐complexity products but not for low‐complexity products, emphasizing the need to adopt different approaches when developing eco‐innovations to ensure favorable consumer reactions (Study 2); and (3) a significant impact of the detachability of eco‐innovative attributes on consumers' perceptions of trade‐offs between environmental benefits and product functionality and on their intentions to adopt eco‐innovations (Study 3). These findings add to existing theoretical knowledge, provide actionable managerial implications, and identify fruitful avenues for future research.     

Exploring pupils’ beliefs about designers and designing

The purpose of this paper is to report on an investigation into pupil beliefs about designers and designing conducted as part of a research project focussing on Designerly Activity in Secondary Design and Technology which builds upon a pilot study (Barlex and Trebell in Int J Technol Design Educ, 2007). Four research questions drove this element of the study: (a) What do pupils believe designers do? (b) What do pupils believe about the knowledge and skills designers must possess? (c) What do pupils believe designers are like? (d) What do pupils believe about the design decisions made by the designer of a given product? This paper compliments the work of Welch et al. (Designing the future: The design and technology association international research conference 2006, University of Wolverhampton, Telford, 2006) relating to student beliefs about designers and designing by drawing on some elements of the research design to inform this study. Pupil responses to questions relating to the role of the designer, what designers are like and what designers need to know are in line with the findings of Welch et al. (Designing the future: The design and technology association international research conference 2006, University of Wolverhampton, Telford, 2006) in their study of elementary students beliefs about designers and designing with both studies concluding that the qualities ascribed to the designer are positive and non-stereotypical—they can be young or old, female or male.     

Personality and other attributes,qualities, abilities and opinions of some ‘A’ level design students

Many claims have been made of a subjective nature that some students studying A level Design develop certain personal qualities and attributes not found in some students who study other academic A levels. The research describes attempts to quantify these claims and as a result provides a firmer basis for the understanding of the effects on students of studying design.     

Kundenpräferenzen für leistungsrelevante Attribute von Stromprodukten

This article addresses whether standard electricity products in Switzerland meet the preferences of private customers. To determine customers’ preferred electricity product we conducted an online survey with choice experiments implying 9420 choice decisions by 628 respondents in Switzerland. Using hierarchical Bayes estimation we determined customer preferences and the importance of individual product attributes in product choice. This procedure makes it possible to calculate part worth utilities for product attributes and to derive customers’ implicit willingness to pay. The “electricity mix” had the most important influence on choice decisions, followed by “monthly electricity costs” and the “location of the electricity generation”. The current Swiss electricity mix which consists of mainly nuclear and hydro power was only rated second to last in a comparison of five alternative mixes. Customers clearly prefer electricity mixes containing green energy. Findings of this study reveal strategic options for product design, positioning, and marketing for a liberalized electricity market.     

Applying Hedonic Pricing Models and Factorial Surveys at Parker Pen to Enhance New Product Success

Walking the path from new product concept to successful commercialization is a tightrope act. Product developers must carefully balance a variety of factors, including predictions of consumer price sensitivity as well as which combination of product attributes will be most valued by the intended market. A well-chosen mix of analytical tools can enhance a firm's chances of accurately predicting market demand. Chuck Tomkovick and Kathryn E. Dobie describe how the integration of two product attribute assessment techniques–hedonic pricing models and factorial surveys–allows product designers to more accurately gauge price sensitivity and market receptivity to new product designs. They also describe how these analytical tools were used to improve decision-making in product development at the Parker Pen Company, and they discuss the role these tools can play in facilitating the transition from concept to commercialization. Hedonic price analysis is an econometric method for determining the value purchasers place on attributes of existing products. In product development, factorial surveys are used to identify the value members of the target market place on new product concepts and prototypes. When used in combination with identified hedonic prices, the responses to a factorial survey allow product developers to predict consumer willingness-to-pay for various combinations of new product attributes. Following development of prototypes for two new product lines, product developers at the Parker Pen Company used hedonic pricing models and factorial surveys as a means for reducing demand uncertainty and for clarifying what consumers were willing to pay for various combinations of product attributes that were under consideration. The integration and use of these techniques involved a five-step process of target market identification, product attribute identification, hedonic price estimation, administering of the factorial survey, and determination of consumer willingness-to-pay. The results of these analyses allowed Parker Pen to better focus product development efforts on those design elements for which test market customers indicated both demand and willingness-to-pay. The Parker Pen Company found hedonic pricing and factorial surveys useful for predicting both the rate and the degree of change in consumers' marginal utility for specific product attributes. The usefulness of these techniques also extends beyond the early stages of new product conception. These techniques are helpful in the development and implementation of dynamic new product marketing mix strategies, including such elements as product design, pricing, channel selection, and promotion.     

The effects of emotional intelligence on job performance and life satisfaction for the research and development scientists in China

To demonstrate the utility of the emotional intelligence (EI) construct in organizational studies, this study focuses on the effect of EI on job performance among research and development scientists in China. We argue that EI is a significant predictor of job performance beyond the effect of the General Mental Ability (GMA) battery on performance. This predictor effect is supported by results on a study of research and development scientists working for a large computer company in China. Our results also show that a self-reported EI scale developed for Chinese respondents, the WLEIS, is a better predictor of job performance than the scale developed in the U.S., the MSCEIT. Implications of the findings are discussed.

Evidence of the practical utility of Wong’s emotional intelligence scale in Hong Kong and mainland China

Emotional intelligence (EI) has been an emerging topic for psychological, educational, and management researchers and consultants in recent years. However, there is a lack of scientifically valid measures of this concept, especially for those that have practical utility in the Asian context. Recently, a 40-item forced-choice instrument was developed for Chinese respondents in Hong Kong. We collected data in three studies to further test the practical utility of this instrument in Hong Kong and mainland China. The results provided clear evidence for the instrument’s practical utility. More research that uses this measure in Asian countries is required.
