Knowledge Reuse for Customization: Metamodels in an Open Design Community for 3d Printing

Theories of knowledge reuse posit two distinct processes: reuse for replication and reuse for innovation. We identify another distinct process, reuse for customization. Reuse for customization is a process in which designers manipulate the parameters of metamodels to produce models that fulfill their personal needs. We test hypotheses about reuse for customization in Thingiverse, a community of designers that shares files for three-dimensional printing. 3D metamodels are reused more often than the 3D models they generate. The reuse of metamodels is amplified when the metamodels are created by designers with greater community experience. Metamodels make the community's design knowledge available for reuse for customization-or further extension of the metamodels, a kind of reuse for innovation

Self-regulated learning and knowledge sharing in the workplace

This study explores how experts in a global multinational company self-regulate their learning. It investigates experts‟ perceptions of the impact of knowledge sharing on their learning and work. Findings indicate that self-regulated learning (SRL) is a highly social process that is structured by and deeply integrated with work tasks. Experts tend to draw heavily upon their personal networks of trusted colleagues in the process of diagnosing and attaining their learning goals. In contradiction to existing models, SRL in the workplace does not appear to be a clearly delineated, linear process comprised of discrete stages. Further research is needed to understand tacit practices of SRL in the workplace

Experienced and Novice Investors: Does Environmental Information Influence on Investment Allocation Decisions?

This paper examines the effect of environmental information on the investment decisions of investors. The motivation for the experimental design applied in this study is that unless actual decision making is observed, the potential usefulness of environmental information (or lack thereof) cannot be taken for granted. The study is based on an experiment where groups of investors (varied by experience) were asked to make investment allocation decisions based on financial information and on supplementary environmental information (varied between cases). As an investment allocation decision (varied by investment horizons) the groups were asked to allocate funds to two companies based on the available information. The findings suggest that environmental information has the potential to influence investment allocation decisions. The findings also suggest that the influence of environmental information on investment allocation decisions is mitigated by the variables considered explicitly in this study, i.e., the investment horizon (varied as short and long) and investor experience (varied as novice and experienced investor). It is concluded that because allocation decisions are multifaceted problems, mixed results related to the influence of environmental information should be expectedEnvironmental reporting; Environmental disclosures; Allocation; Decision making; Investment horizon; Investors; Experiment;

The design thinking approaches of three different groups of designers based on self-reports

This paper compares the design thinking approaches of three groups of student-designers: industrial design and architecture undergraduates, and design PhD candidates. Participants responded to an open-ended design brief, working individually. Upon submission of their designs they were debriefed about their design processes. We compare the groups based on their submissions and self-reported design activities, especially the sequence of their design activities and the time allotted to them. There were some commonalities and differences between the two undergraduate groups but the main differences were between the two undergraduates and the PhD students. On the basis of the findings we pose questions regarding design methods in the era of 'design thinking' wherein designers are required to adopt an entrepreneurial frame of mind

Using protocol analysis to explore the creative requirements engineering process

Protocol analysis is an empirical method applied by researchers in cognitive psychology and behavioural analysis. Protocol analysis can be used to collect, document and analyse thought processes by an individual problem solver. In general, research subjects are asked to think aloud when performing a given task. Their verbal reports are transcribed and represent a sequence of their thoughts and cognitive activities. These verbal reports are analysed to identify relevant segments of cognitive behaviours by the research subjects. The analysis results may be cross-examined (or validated through retrospective interviews with the research subjects). This paper offers a critical analysis of this research method, its approaches to data collection and analysis, strengths and limitations, and discusses its use in information systems research. The aim is to explore the use of protocol analysis in studying the creative requirements engineering process.<br /

A literature review of expert problem solving using analogy

We consider software project cost estimation from a problem solving perspective. Taking a cognitive psychological approach, we argue that the algorithmic basis for CBR tools is not representative of human problem solving and this mismatch could account for inconsistent results. We describe the fundamentals of problem solving, focusing on experts solving ill-defined problems. This is supplemented by a systematic literature review of empirical studies of expert problem solving of non-trivial problems. We identified twelve studies. These studies suggest that analogical reasoning plays an important role in problem solving, but that CBR tools do not model this in a biologically plausible way. For example, the ability to induce structure and therefore find deeper analogies is widely seen as the hallmark of an expert. However, CBR tools fail to provide support for this type of reasoning for prediction. We conclude this mismatch between experts’ cognitive processes and software tools contributes to the erratic performance of analogy-based prediction

A New Consumerism: The influence of social technologies on product design

Social media has enabled a new style of consumerism. Consumers are no longer passive recipients; instead they are assuming active and participatory roles in product design and production, facilitated by interaction and collaboration in virtual communities. This new participatory culture is blurring the boundaries between the specific roles of designer, consumer and producer, creating entrepreneurial opportunities for designers, and empowering consumers to influence product strategies. Evolving designer-consumer interactions are enabling an enhanced model of co-production, through a value-adding social exchange that is driving changes in consumer behaviour and influencing both product strategies and design practice. The consumer is now a knowledgeable participant, or prosumer, who can contribute to user–centered research through crowd sourcing, collaborate and co-create through open-source or open-innovation platforms, assist creative endeavors by pledging venture capital through crowd funding and advocate the product in blogs and forums. Social media- enabled product implementation strategies working in conjunction with digital production technologies (e.g. additive manufacture), enable consumer-directed adaptive customisation, product personalisation, and self-production, with once passive consumers becoming product produsers. Not only is social media driving unprecedented consumer engagement and significant behavioural change, it is emerging as a major enabler of design entrepreneurship, creating new collaborative opportunities. Innovative processes in design practice are emerging, such as the provision of digital artifacts and customisable product frameworks, rather than standardised manufactured solutions. This paper examines the influence of social media-enabled product strategies on the methodology of the next generation of product designers, and discusses the need for an educational response
