Effective visualisation of design versions : visual storytelling for design reuse

Improving and supporting the process of design knowledge reuse can increase productivity, improve the quality of designs and lead to corporate competitive advantage. Whereas internal knowledge reuse (reusing knowledge from one’s personal memory or experiences) is very effective, external knowledge reuse (reusing knowledge from an external digital or paper archive) often fails. This paper studies the value of the storytelling paradigm in supporting reuse from an external repository. Based on a formalisation of the internal reuse process from ethnographic studies, a prototype system, CoMem (Corporate Memory) is presented, which supports the reuse process, specifically the steps of finding and understanding reusable items. This paper focuses on the ability of designers to understand designs that are found in corporate repositories. It is argued that in order to understand and reuse a found design, the designer needs to see the evolution of that design during the original design process. An Evolution History Explorer module of the CoMem system is presented that uses a storytelling metaphor and lays out versions visually side-by-side. A formal user evaluation of CoMem supports the hypotheses that (1) exploring the evolution of a design improves the reuse process, and (2) that visual storytelling is an effective paradigm for supporting that exploration

AEC Global Teamwork: Emergent Work Processes

This ethnographic study reports on emerging work processes and practices observed in the AEC (Architecture/Engineering/Construction) Global Teamwork program, i.e., what people experience when interacting with and through collaboration technologies, why people practice in the way they do, how the practice fits into the environment and changes the work patterns. It presents the experience of two high-performance typical but extreme AEC teamwork cases adopting and adapting to collaboration technologies and how these technologies in practice impact their work processes. The findings illustrate the importance of collaboration technologies in cross-disciplinary, global teamwork. Observations indicate that high performance teams that use the collaboration technologies effectively exhibit collaboration readiness at an early stage and manage to define a “third way” to meet the demands of the cross-disciplinary, multi cultural and geographically distributed AEC workspace. The observations and implications represent the blueprint for yearly innovations and improvements to the design of the AEC Global Teamwork program

A Framework to Analyze Knowledge Work in Distributed Teams

This article presents a framework to analyze knowledge work in the changing context of new ways of working. Knowledge work increasingly takes place as collaboration from different and changing workplaces due to mobility, multilocational, and geographical distribution of participants. We define the framework based on five key factors that pose challenges to the performance and productivity of knowledge work performed in distributed teams. The framework extends and integrates traditional performance models of task, team structure, and work process, with context factors like workplace, organization policy, and information and communication technology (ICT) infrastructure. The framework is applied in a qualitative comparative cross-case analysis to eight globally distributed teams in two Fortune 100 high-tech companies. We conclude with a series of specific challenges for each factor when studying distributed knowledge work. It is shown that due to changing contexts knowledge workers, teams, and organizations need to constantly adapt, readjust, and realign according to the five factors

Discovery of Re-usable Architecture/Engineering Construction Knowledge Trough Exploration of a Corporate Memory : Chance Discovery of Reusable AEC Knowledge from a Corporate Memory

Re-using knowledge in architecture, engineering and construction (AEC) firms can lead to greater competitive advantage, improved designs, and more effective management of constructed facilities. This paper discusses the importance of exploration and discovery of reusable knowledge from a corporate archive as opposed to simple search and retrieval. We describe and illustrate through a scenario of use an exploration framework and prototype, CoMemTM that formalizes the added value of exploration in the process of knowledge reuse. We discuss two exploration activities: (i) Breadth- Only overview exploration that assist a user to rapidly localize pockets of re-usable knowledge from the large corporate archive and (ii) Iterative breadth-depth exploration that enables a user to identify those re-usable components of the Corporate Memory that may yield design issues that were not originally considered

Collaborative Exploration of Rich Content in Support of Knowledge Re-use

A/E/C Team members, while collaborating on building projects, rely on past experiences and content through the use of project design archives (whether in paper or digital format). This leads to underutilization of potential knowledge, as decision-making of data, information, and knowledge reuse is limited by access to these archives, due to sheer size and inconvenient presentation. This paper presents an integrated solution that leverages two technologies CoMem (Corporate Memory) and iRoom (interactive Room) developed at Stanford. This addresses critical limitations, i.e., content, context, visualization and interactivity, constraining the process of collaborative exploration towards knowledge reuse and decision-making

Fiddlers Green College: Looking for Equitable Workforce Pathways in Silicon Valley

Often, research on the efficacy of postsecondary workforce programs does not convey their impact on true social mobility. The purpose of this study is to investigate project-based Career and Technical Education (CTE) workforce pathways in Silicon Valley. This study takes a step towards better understanding what constitutes the metrics that explain functioning pathways. In contributing to Project-Based Learning (PBL) theory, Amaral et al. (2015) found that seven PBL essentials form good learning outcomes; Creghan and Adair-Creghan (2015) then showed a measurable outcome of PBL is higher attendance, to which Plasman and Gottfried (2020), using a case of Applied STEM CTE (AS-CTE), framed attendance as a predictor of the efficacy of a workforce pathway. Recommendation: Through ethnography, the investigators observed that when social mobility was added as a metric of high quality PBL with AS-CTE in a predictive ontology framework of education success, an improved level of attendance was observed. The authors conclude that using the seven essentials and social mobility as a metric of PBL helps explain the observation of PBL’s improved efficacy. Hence, social mobility should be a metric of PBL AS-CTE program outcomes

Realism and control : problem-based learning programs as a data source for work-related research

Problem-based learning (PBL) is a pedagogical methodology that presents the learner with a problem to be solved to stimulate and situate learning. This paper presents key characteristics of a problem-based learning environment that determines its suitability as a data source for workrelated research studies. To date, little has been written about the availability and validity of PBL environments as a data source and its suitability for work-related research. We describe problembased learning and use a research project case study to illustrate the challenges associated with industry work samples. We then describe the PBL course used in our research case study and use this example to illustrate the key attributes of problem-based learning environments and show how the chosen PBL environment met the work-related research requirements of the research case study. We propose that the more realistic the PBL work context and work group composition, the better the PBL environment as a data source for a work-related research. The work context is more realistic when relevant and complex project-based problems are tackled in industry-like work conditions over longer time frames. Work group composition is more realistic when participants with industry-level education and experience enact specialized roles in different disciplines within a professional community

Degrees of Engagement in Interactive Workspaces

Abstract. This paper presents a new perspective of the impact of collaboration technology on the degrees of engagement and specific interaction zones in interactive workspaces. The study is at the intersection of the design of physical work spaces, i.e., bricks, rich electronic content such as video, audio, sketching, CAD, i.e., bits, and new ways people behave in communicative events, i.e., interaction. The study presents: (1) an innovative multimodal collaboration technology, called RECALL TM, that supports the seamless, realtime capture of concept generation during project brainstorming and project review sessions, (2) the deployment of RECALL TM in an interactive workspace that supports real project review sessions called Fishbowl, and (3) the observations of the impact of RECALL TM and the interactive workspace on degrees of engagement and interaction zones as it is deployed in the specific Fishbowl sessions

Communication, trust and performance: The influence of trust on performance in A/E/C cross-functional, geographically distributed work

CIFE Working Paper #78The purpose of this paper is to report the results of the CIFE research study of trust in cross-functional, geographically distributed A/E/C teams. Cross-functional, geographically distributed teams provide the construction industry with great advantages by bringing diverse skills to bear on problems and projects that span traditional organizational functions. Although companies are quickly adopting the model of cross-functional, geographically distributed teams, little is known about the new social environment that this creates for team members. A major challenge in such teams is the development of interpersonal trust between team members. The objective of this research is to determine the influence of geographic distribution, cross-functionality on communication, interpersonal trust and individual performance between two team members, called a dyad, in an Architecture, Engineering and Construction (A/E/C) industry setting. Our research questions were: What are the key predictors of interpersonal trust in distributed A/E/C teams? And how does interpersonal trust influence individual performance? We hypothesized that trust is more difficult in cross-functional, geographically distributed dyads because of the different disciplinary perspectives and the lack of face-to-face interaction available when working at a distance. We also hypothesize that trust improves the work process performance of both members of the dyad, i.e. the trustor and the trustee, leading to greater work outputs, such as less time, less cost and higher quality
