ABSTRACT The generation of ideas is an essential element in the process of design. One suggested approach to improving the quality
of ideas is through increasing their quantity. In this study, concept generation is examined via brainstorming, morphology
charts and sketching. Statistically significant correlations were found between the quantity of brainstormed ideas and design
outcome. In some, but not all, experiments, correlations were found between the quantity of morphological alternatives and
design outcome. This discrepancy between study results hints at the role of project length and difficulty in design. The volume
of dimensioned drawings generated during the early-to-middle phases of design were found to correlate with design outcome,
suggesting the importance of concrete sketching, timing and milestones in the design process.

    • "From this perspective prototyping represents an important design practice and, as such, a central element in corporate innovation processes (Bogers and Horst, 2013, Leonard and Rayport, 1997). Whilst firms already use prototypes to gather external feedback in industries where design conveys symbolic know-how (for instance, home furnishing manufacturers 'test' their prototypes during exhibitions and fairs, D'Ippolito et al., 2013), in other industries prototypes mainly constitute the artefact based on which within-the-firm interactions allow the initial concept to mature (Tovey et al., 2003, Yang, 2009). With the aim of understanding how prototyping can support design practices, Bogers and Horst (2013) have investigated how collaborative prototyping could improve product usability and usefulness. "

    ABSTRACT: Scholars dedicated increasing attention towards appreciating how design has changed individuals' perception of new products, firms' understanding and formulation of strategy, or other relevant actors' approach to innovation and technology management. By emphasising the importance of design for the definition of consumers' needs, the restructuring of firms' organisational structures and strategies, and the evolution of firms' value creation processes, this review paper identifies relevant research gaps and questions that would benefit from future scholarly attention. In particular, it is suggested that such effort should address the analysis of: how design consumption can help better comprehend consumers' needs; what are the implications of design thinking on the skill sets of design professionals; the organisational structure of firms, including the reconfiguration of other business functions, and their strategy; and whether and how design thinking can shape firms' value creation processes and contribute to the formalisation of design tasks.

    • "Their statistical analysis revealed that the quantity of concepts significantly correlated with project grades. Yang [21] also found that preliminary sketching and prototyping led to better project grades. Although informative, these experiments included only student projects and hence the results cannot be transferred directly to company or industrial project settings; thus, an extension of the above-cited work in such settings is needed.

    ABSTRACT: The development of product-service innovation projects within the context of a company is not yet supported by clear theories and methodologies. Our objective is to analyze innovation and idea generation for such projects from the fuzzy front end to the selected design concept, assessing their potential to be successfully developed and launched on the market. We present a protocol study, using which data derived from 19 innovation projects of five types and conducted by 86 students are analyzed. Sixty-one variables are observed, thus generating 700 data vectors. Bayesian network learning is used to explore conditional inferences among these variables. We examine conditional probabilities between the innovation process means and the significant results produced for the company, modulated by the influence of contextual variables. A number of surprising findings are drawn about the link between problem setting and problem solving processes, the importance of certain contextual variables, and the potential discrepancies between the apparent and produced results of innovative projects. Conducted analyses imply the need for novel innovation evaluation frameworks.

    • "Kurtoglu et al. (2009) evaluated an online design library procedure integrating artificial intelligence principles. M Yang (2009) studied correlations between concept quantity and quality for brainstorming, morphology charts, and sketching procedures. Others have studied the effects of education and pedagogy on creative design activities. "

    ABSTRACT: This paper presents the results of an empirical study of concept generation procedures enabling flexibility in engineering systems design. Evaluation of two educational training procedures (analogies vs. explicit) and two ideation procedures (free undirected brainstorming vs. prompting) was done. The procedures aim to improve quantitative lifecycle performance, while providing users with satisfaction with the process. Controlled experiments involved ninety participants working on a design problem in emergency services. Results suggest that combining explicit training on flexibility and free undirected brainstorming was best to improve lifecycle performance, measured as average response time and net present cost of infrastructure. No statistically significant effect was measured when comparing procedures against one another based on lifecycle performance, suggesting that any procedure could be used. Analogies combined with free undirected brainstorming led to better process satisfaction for users. The results give insights on the true effects of concept generation procedures, considering quantitative performance impacts, as well as qualitative user impressions.
