“…The types of think-aloud experiment and variations in their format differ within the literature, from concurrent think-aloud to retrospective studies (Perry and Krippendorff 2013). The length of time provided for a think-aloud session also varies from several hours to as little as 15 minutes (Jiang 2009, Chai andXiao 2012).…”

“…Whilst the sample size is similar to other protocol studies of design activity (Suwa, Purcell et al 1998, Almendra and Christiaans 2009, Perry and Krippendorff 2013, the statistical analysis is based upon a relatively small number of participants. Moreover, although possessing a design education, internship and industrial experience, the subjects may not be described as designers at the highest level of knowledge and skills acquisition (Dreyfus andDreyfus 1980, Lawson andDorst 2009).…”

Abstract:The study compared the use of digital and conventional sketching as influence upon conceptual design work. Results show a significantly increased focus of attention upon the sketching tool in the digital condition compared to conventional sketching with pen and paper. Both a statistical analysis and fine-grained qualitative comparison illustrate how increased frequencies of sketching tool focused activities resulted in both significantly more time spent in problem orientated work and the fragmentation of attempts to transition from problem definition to generative solution ideation. In contrast, reduced tool-focused activity in the conventional sketching condition appeared to provide opportunities for significantly increased solution ideation through design-driven moves to explore reflect upon and develop solution propositions. The implications of a tool orientated focus of attention are discussed in terms of its impact upon reflective solution ideation during conceptual design.

“…The latter, on the contrary, is related to the deepening of the design space by means of an idea that is more detailed than the previous one. A recent work by Perry and Krippendorf [16] argues that the segmentation from the transcriptions of the whole design discourse into design moves is not a repeatable process, which largely depends on the analysts and their experience. Therefore, they claimed that there exists a clear need for better and more robust definition of the coding schemes, so as to remove ambiguities and improve the reliability of design protocol studies.…”

This paper presents an original approach for the analysis of design protocols. It presents a coding scheme based on the OTSM-TRIZ Network of Problems, so as to map the protocols by both considering design moves and their mutual relationships with links. Stemming from this coding scheme, the authors propose a novel set of rules for the identification of cognitive processes to be integrated into a Computer-aided tool, so as to reduce the time employed for the analysis of design protocols. The five preliminary tests carried out to verify the potentiality and the feasibility of the approach have demonstrated that it provides good results both in terms of quality and in terms of time-savings for the whole protocol analysis.

Competency-based measure is increasingly evident as an effective approach to tailoring training and development for organisational change and development. With design stage widely reckoned as being decisive for construction waste minimization, this study aims at identifying designers' competencies for designing out waste. Due to paucity of research into competency for construction waste mitigation, this study corroborates Verbal Protocol Analyses (VPA) with phenomenological research. Combining findings from the two methodological approaches, competencies for designing out waste are grouped into five categories, three of which are largely task related and two being contextual competencies.The study suggests that design task proficiency, low waste design skills and construction related knowledge are indispensable task competencies, while behavioural competence and inter-professional collaborative abilities are requisite contextual competencies for designing out waste.In concurrence with task-contextual theory of job performance, personality variables and cognitive abilities are found to influence one another. This suggests that both task and contextual competencies are not only important, they are less mutually exclusive with respect to designing out waste. This study implies that apart from commitment and dedication of designers to waste minimization, design and firm practices are expected to be adapted to the industry's standard. Basis for training needs of design professionals as well as redeployment criterion are further elaborated in the paper. By enhancing competencies identified in this study, construction waste would not only be significantly designed out, adequate cost saving could be made as a result of waste reduction.
