Engineering sketches and drawings are the building blocks of technological design and production. These visual representations act as the means for organizing the design to production process, hence serving as a "social glue" both between individuals and between groups. The author discusses two main capacities such visual representations serve in facilitating distributed cognition in team design work As conscription devices, they enlist and organize group participation. As boundary objects, they facilitate the reading of alternative meanings by various groups involved in (...) the design process. The introduction of computer-aided design into this visual culture of engineering restructures relationships between workers in ways that can hamper the flexibility necessary for these crucial capacities to take place. The data are drawn from a study of the daily practices of engineers engaged in redesigning a turbine engine package. The method is participant observation. (shrink)

A decision delay can translate into significant financial and business losses. One way to accelerate the decision process is through improved communication among the stakeholders engaged in the project. Capturing, transferring, managing, and reusing data, information, and knowledge in the context it is generated can lead to higher productivity, effective communication, reduced number of requests for clarification, and a shorter time-to-market cycle. We formalized the concept of reflection in interaction during communicative events among multiple project stakeholders. This concept extends Donald (...) Schon’s theory of reflection in action of a single practitioner. We model the observed reflection in interaction with a prototype system called TalkingPaperTM. It is a ubiquitous client-server collaborative environment that facilitates knowledge capture, sharing, and reuse during synchronous and asynchronous communicative events. TalkingPaperTM bridges the paper and digital worlds. It transforms the analog verbal discours, annotated paper corporate documents, and the paper and pencil sketches into indexed and synchronized digital content that is published on and streamed on-demand from a TalkingPaperTM web server. The TalkingPaperTM sessions can be accessed by all stakeholders for rapid knowledge sharing and decision-making. (shrink)
