Use of requirement traceability in collaborative design environments

Object sharing in computer supported collaborative design requires multiple participants not only to be able to modify design objects when participating in a collaborative design scenario, but also be able to query them for specific information. Especially in the design of complex artefacts, such as buildings, as the relationships that need to be tracked and dependencies between the participants and created objects increase, so do the difficulties of converging on a single design. Often the shared objects are represented with their most salient design attributes, such as geometric information, to assist computer supported collaborative work (CSCW). Capturing non-geometric information in CSCW requires a shift in the way design objects are represented and queried. In this paper, we present our work in computer aided requirement traceability for architectural design, which addresses an alternative way to parse design objects to assist object sharing in collaborative design.

Co-creating external design representations: Comparing face-to-face sketching to designing in virtual environments

While developments in computer-supported collaborative work tools, computer aided design and the availability of high bandwidth networks offer alternative collaborative environments for design, the alternatives have yet to be characterised in terms of their impact on the co-creation of a shared model. A specific collaborative design environment makes a commitment to the way in which the designers can communicate and co-create an external representation of the shared design model. This research focuses on the impact of alternative collaborative virtual environments on design behaviour and collaborative processes. An experiment was conducted to identify similarities and differences between co-located collaborative designing using sketches as the external representation and remote collaborative designing sessions using sketches and 3-D models. The results of this study are discussed in terms of: (1) the effect of being remotely located; (2) the effect of the type of external representations.     

Towards participatory design in craft and design education

The purpose of the present study was to analyze the differences and effects of user participation in university level students' collaborative design processes. The study focused on how intended users (i.e., frequent conference-goers) participated in a product design process (designing conference bags) and how much influence these conference-goers had on students' design solutions. The data were derived from a collaborative learning environment (Future Learning Environment, FLE2), which provided a distributed database for students' and users' dialogue. The study employed qualitative content analysis of users' written messages posted on the database. The analysis indicated users' contributions to the functional, expressive and aesthetic design solutions. From the students' standpoint, it was challenging to treat contradictory information produced by users and to find optimal design solutions.

Development of CDPM matrix for the measurement of collaborative design performance in construction

The widely realized importance of collaborative design and work has led to the development of frameworks/tools to support collaboration in the construction industry. However, there is a lack of widely accepted indicators and criteria to assess the performance of collaborative designs. This paper aims to develop a matrix which could be used to measure the performance of a collaborative design. The criteria involved will, in turn, provide a guideline for the improvement of the final design output. The research involved a literature review and in-depth focus group workshops. The outcome of the study is a collaborative design performance measurement (CDPM) matrix that addresses 6 indicators and 42 detailed criteria. The matrix can be applied to support design teams in measuring and improving their performance, by reviewing and modifying collaborative design development, identifying the design team strengths and weaknesses, improving communication and suggesting suitable responsive actions.     

Integrated system for BIM-based collaborative design

For effective collaboration among construction project participants, the use of Building Information Model (BIM) has become more common throughout the building life cycle. However, due to the use of different BIM-based software among collaborators during the design, a variety of problems have occurred, including loss of data, difficulty in communication, and poor work efficiency. Hence, this study proposes an integrated design system for the improvement of BIM-based collaborative design. For this purpose, problems are derived based on an analysis of conventional BIM-based collaborative design. In addition, a concept for the development of the BIM-based integrated design system is established from integration methodologies. Based on ‘functional integration,’ ‘integrated information management’ and ‘integrated process support,’ the integrated design system is implemented through the combination of three modules: BIM Modeler, BIM Checker and BIM Server. To test the integrated design system, a case study on a hospital building design is reviewed, and improvements compared to the conventional system are examined. It appears that the proposed system can enhance design quality and productivity by providing necessary support for collaborative design in an integrated manner.     

Virtual environments for collaborative design: requirements and guidelines from a social action perspective

The paper is concerned with the design of virtual environments for collaborative design (VECD) – a particular class of collaborative virtual environments (CVEs) that focus on supporting design activities. VECD are becoming essential collaboration platforms for many designers and their clients, in a wide range of design domains including product, interior, architectural, automotive design, etc. However, the contemporary design considerations of VECD are mainly driven by systematic approaches that do not reflect upon knowledge regarding requirements that stem out of everyday collaborative design activities. A consequence is that they do not yield methodical guidance to designers of VECD applications. This paper takes a social action standpoint for the purposeful identification and organisation of collaborative design activities; proposes guidelines at multiple levels of abstraction for the design of VECD; and, finally, applies these to a case study development of a specific VECD for interior space design. The paper provides practical aids to designers of VECD so that they incorporate requirements about collaborative design early in the development lifecycle.
