Using Group Decision Support System to Support Value Management Workshops

A group decision support system (GDSS) is an interactive computer-based information system that combines the capabilities of communication technologies, database technologies, computer technologies, and decision technologies to support the identification, analysis, formulation, evaluation, and solution of semistructured or unstructured problems by a group in a user-friendly computing environment. As there is a strong demand for improvements to the practice of value management (VM), research has been conducted to design a GDSS prototype system, named the interactive value management system (IVMS), to explore its potential application in VM workshops and to investigate the effect of the application. The paper begins with an introduction to the problems of implementing VM in the Hong Kong construction industry and then proceeds to an illustration of the features of the proposed system, which has been developed in the research. Two validation studies designed to test the support of the proposed system are described and the results discussed. Findings from this research indicate that IVMS is supportive in overcoming the problems and difficulties in VM workshops.     

Pedagogy of Teaching Value Management in Postgraduate Construction and Property Program

As value management (VM) has been increasingly applied to enhance value in public construction projects, the core subject entitled “Value Management for Construction and Property” is being offered to postgraduate students in the Department of Building and Real Estate at the Hong Kong Polytechnic University. Under the new outcome-based curriculum, the learning outcomes, pedagogy of teaching VM, and activities of the VM workshops for the subject are described in this paper. The results of a questionnaire survey of the students’ feedback on the performance of the workshops for the academic year 2007–2008 are presented and discussed. Students believed that value management workshops are essential in the curriculum. They expressed that it was a valuable experience to participate in the VM workshop which enabled them to have a better understanding of the subject. Some improvement is also recommended for future organization and management of workshops based on the lessons learned in these workshops.

Cognitive stimulation in brainstorming.

Research on group brainstorming has demonstrated that it is less effective for generating large numbers of ideas than individual brainstorming, yet various scholars have presumed that group idea sharing should enhance cognitive stimulation and idea production. Three experiments examined the potential of cognitive stimulation in brainstorming. Experiments 1 and 2 used a paradigm in which individuals were exposed to ideas on audiotape as they were brainstorming, and Experiment 3 used the electronic brainstorming paradigm. Evidence was obtained for enhanced idea generation both during and after idea exposure. The attentional set of the participant and the content of the exposure manipulation (number of ideas, presence of irrelevant information) influenced this effect. These results are consistent with a cognitive perspective on group brainstorming. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Endothelin-1 expression during early response after antigen challenge in brown-norway rats

HEALNet, a Canadian Network of Centres of Excellence Program, has undergone a building exercise to focus and consolidate its research program for the 1998 to 2002 funding period. A number of challenges were identified while trying to develop this research agenda within a short time frame. These included how to bring together a diverse group of researchers, ensuring that everyone's voice was heard, and ensuring that the collective interests were placed ahead of individual interests. Furthermore, as three separate workshops were being held, a method for quickly capturing the workshop output and preparing reports was required. A Group Support System (GSS) was used to facilitate this work and to help meet these challenges. This report describes how the GSS was used. While the GSS supported brainstorming activities, it was less useful in assisting the group in developing the details of research programs. It did facilitate the timely production of reports from the workshops. Such systems have a role to play in supporting group work at the idea generation stage, but further work is required in order for them to be useful in the development of detailed research programs.     

Improving group decisions by better pooling information: A comparative advantage of group decision support systems.

This study compared a group decision support system (GDSS) with face-to-face (FTF) group discussion on characteristics of information exchange and decision quality. Participants given conflicting information tended to share more of their unique data and engaged in more critical argumentation when using the GDSS than when meeting FTF. Conversely, when information was consistent among members, there were no such differences between FTF and GDSS groups. The GDSS groups significantly outperformed the FTF groups in agreeing on the superior hidden profile candidate, especially when there was a lack of prediscussion consensus. Individual-level analyses revealed that members of GDSS groups that did not have a prediscussion consensus tended to experience stronger preference shifts toward the group's consensus decision.

Effects of leadership style and anonymity on group potency and effectiveness in a group decision support system environment.

A longitudinal laboratory experiment was conducted to evaluate the effects of leadership style (transactional vs transformational) and anonymity level (identified vs anonymous) on group potency and effectiveness of 36 undergraduate student work groups performing a creativity task using a Group Decision Support System (GDSS). GDSS are interactive networks of computers for generating solutions to unstructured problems. Results indicated that GDSS anonymity amplified the positive effect of transformational leadership on group potency relative to transactional leadership in the group writing session of the task. GDSS anonymity also increased the effect of transformational leadership relative to transactional leadership on group effectiveness. Implications for practice and future research are discussed.

Cognitive stimulation and problem presentation in idea-generating groups.

One technique that may facilitate group brainstorming is decomposition of the task so that categories of the problem are considered one at a time rather than simultaneously (A. R. Dennis, J. S. Valacich, T. Connolly, & B. E. Wynne, 1996). Two studies examined this possibility for both solitary and interactive brainstorming in which major categories of a brainstorming problem were presented simultaneously or sequentially. In the 1st study, participants in the sequential presentation condition generated more ideas than did those in the simultaneous condition in both the individual and the group conditions. In the 2nd study, individuals exposed to either a high number or low number of idea categories demonstrated enhanced performance. Simulations of the data demonstrated that the results were consistent with an associative memory model of the idea generation process.

Internship Workshops on Psychopathology: Bridging the Academic-Clinical Gap.

Reports on a brief orientation program designed to familiarize new interns with some of the major signs of psychopathology they will encounter and to help bridge gaps in training for individual interns. The orientation consists of four 1-day workshops focusing on the areas of depression, suicide and hospitalization, schizophrenia, and neuropsychological problems. Completing these intensive workshop experiences provides a brief overview of psychopharmacology and a short introduction to the evaluation process of child problems. The workshops are regarded as important both for the interns and the staff. As the interns become more curious and less defensive about beginning their clinical rotations, the staff become less frustrated about handling the interns' anxieties concerning their lack of preparation for the internship year.

Effects of task instructions and brief breaks on brainstorming.

Experiment 1 examined the effects of additional brainstorming rules for groups and looked at whether the presence of a facilitator who actively enforced the rules of brainstorming was beneficial. Experiments 2 and 3 examined whether the additional rules and brief breaks were beneficial to individual brainwriters and electronic brainstormers working alone. Clear benefits of the additional rules were found under a variety of conditions. The presence of a facilitator to enforce the rules enhanced the efficiency of idea generation (number of words used to express ideas) but not the number of ideas generated. There appears to be a small benefit to taking breaks in brainwriting sessions, but the benefit of breaks is reduced or eliminated in electronic brainstorming sessions.

The eyes have it: Minority influence in face-to-face and computer-mediated group discussion.

Results of an experiment comparing face-to-face groups with anonymous and identified computer-supported groups challenged theoretical arguments (V. S. Rao & S. L. Jarvenpaa, 1991 ) that computer-based group decision support systems (GDSS) can increase group decision quality by facilitating expression of minority opinions. In groups working on a hidden-profile investment decision task, minority opinion holders expressed their arguments most frequently under anonymous GDSS communication, but the influence of the minority arguments on private opinions and on group decisions was highest under face-to-face communication. These results suggest that the conditions that facilitate the expression of minority arguments may also diminish the influence of those arguments. The implications of these findings for a normative view of social influence, for social presence theory, and for the effects of GDSS on participation rates in group discussion are discussed.

Computer brainstorms: More heads are better than one.

Research has consistently found nominal group brainstorming (in which members work separately without communicating) to be superior to brainstorming in which group members interact verbally. This article presents the results of an experiment that found the reverse to be true for computer-mediated electronic brainstorming. In this experiment, 12-member electronically interacting groups generated more ideas than did 12-member nominal groups, and there were no differences between 6-member electronic and 6-member nominal groups. The authors attribute these results to the ability of electronic brainstorming to introduce few process losses (production blocking, evaluation apprehension, and free riding) while enabling process gains (synergy and the avoidance of redundant ideas).

Critical Success Factors for Value Management Studies in Construction

Value management (VM) studies often face pressure caused by limited time and resources. The identification of key factors for value management success enables appropriate allocation of the limited time and resources in order to achieve better output. Most of the related past work only identified critical success factors for value management studies in general. This paper seeks to distinguish these factors according to their degrees of importance in relation to success. A questionnaire survey was conducted to gather views from experts with experience in value management practice. The findings of the survey reveal the relative importance of the nominated success factors. Two factors that had not been highlighted by previous research are identified as having a significant influence on the success of VM studies. In order to explore the underlying construction among the identified critical success factors (CSFs), factor analysis was adopted to investigate the cluster of the relationship. The results indicate that the success of VM studies requires a combined effort from all parties involved.     

Measuring the Performance of Value Management Studies in Construction: Critical Review

Value management (VM) is a useful method to use when dealing with issues such as budget and schedule challenges arising in the construction industry. However, little research has been done to measure the performance of VM studies, which has made many potential users reluctant to use VM. This paper presents a critical review of the development of performance measurement in general and the performance measurement in the construction industry, with a special focus on the performance measurement of VM studies in construction. The strengths and weaknesses of the existing measurement frameworks are investigated in the context of VM studies. It is concluded that traditional performance measurement of VM studies focusing on cost reduction is insufficient. Many other perspectives, such as clarifying objectives, and improving communication among stakeholders, should be considered seriously when making the measurement. This paper reveals that the existing frameworks to measure VM studies are inappropriate. It suggests that perspectives such as multicriteria measurement, flexible framework for different practice, and benchmarking to identify best practice could be adapted to develop a performance measurement framework for VM studies.     

Influence of brainstorming instructions and problem sequence on a creative problem solving test.

"The experiment was designed to study the effects on creative problem solving of instructions to express solutions without evaluation (brainstorming) and instructions which required only solutions of good quality and which involved a penalty for solutions of bad quality (nonbrainstorming). Each S [32 college students] was given two problems which required creative ability, in two testing periods." One was with and one without brainstorming. "Significantly more good solutions were produced under brainstorming… . There was no significant difference in the nonbrainstorming performance in the two test periods."

Considerations for Return to the Moon and Lunar Base Site Selection Workshops

The establishment of a lunar base with a permanent human presence is on the horizon. The scientific importance of the Moon and the potential use of local resources at a lunar base provide valuable concepts to consider. Importantly, there are significant ideas, concepts, and reports from the past, the products of a wealth of “mental calorie” inputs, which should be reconsidered; herein, many of these are placed within an historical perspective, in hopes that we may learn by our past experiences. The 1994 Clementine mission, its instrumentation and returned data, provides the first global coverage of the composition, structure, and topography of the Moon. The planned 1997 Lunar Prospector will add significantly to this database. These new global data are requisite for the selection of a lunar base. It is paramount to consider thoroughly the rationale for site selection, and much of the groundwork for this rationale has already been performed. The selection process should be led by a strategic purpose or vision that considers (1) scientific objectives, both on the Moon, as well as from the Moon (e.g., astronomy); (2) resource utilization; and (3) operational considerations, both orbital and surface. Many of the relationships between these factors were explored during workshops convened at Johnson Space Center by the National Aeronautics and Space Administration (NASA) in April and August 1990. However, these workshops have not resulted in official, catalogued NASA publications. The merits of numerous potential sites were analyzed in terms of lunar geoscience, geophysics, space physics, astronomy, and lunar resources, as well as operational constraints. The considerations and recommendations of the NASA Site Selection Committee should provide the basis for a realistic site selection for a human presence at an outpost on the lunar surface.

The effect of group participation on brainstorming effectiveness for 2 industrial samples.

Problems were presented for brainstorming to 48 research scientists and 48 advertising personnel employed with the Minnesota Mining and Manufacturing Co. Within a counterbalanced experimental design, each S brainstormed certain problems individually and other equated problems as a member of a 4-man team. Individuals produced not only more ideas than groups, but they accomplished this without sacrificing quality. The net superiority of individual performance over group participation is highlighted by the fact that 23 of 24 groups produced a larger number of different ideas under the individual condition. The superiority of individual brainstorming over group brainstorming was relatively greater when it was preceded by group participation. Apparently, group participation is accompanied by certain inhibitory influences even under conditions (e.g., brainstorming) which place a moratorium on all criticism.

A comparison of two group brainstorming procedures.

A modified brainstorming procedure that required Ss (male introductory psychology students) to identify psychologically with significant components of the task (called synectics) was compared to standard brainstorming over 3 sessions and 9 different problems. Each treatment condition was also divided into high- and low-interpersonal-effectiveness groups. The synectics groups were superior to the brainstorming groups on all 9 problems, but the differences were statistically significant for only 4. There were no significant main effects due to group composition, nor were there any interactions. It is concluded that synectics is a more effective group-problem-solving strategy than brainstorming.

Comparison of a written feedback procedure, group brainstorming, and individual brainstorming.

Compared the productivity of a written feedback procedure with that of group and individual brainstorming in 48 undergraduates divided into 4-member groups. The written feedback procedure consisted of group members generating ideas independently, receiving written copies of each other's ideas, and then resuming to work independently. Each group generated solutions to 2 brainstorming problems. The productivity of both the written feedback procedure and individual brainstorming exceeded that of group brainstorming. The productivity of the written feedback procedure did not differ significantly from that of individual brainstorming. Results suggest that, as presently applied, the utility of the written feedback procedure does not exceed that of individual brainstorming. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
