  1. Using group support system in virtual value management workshops for major construction projects YUAN Zhao, Prof. Geoffrey Q.P. Shen Dr. Jacky K.H. Chung

  2. Definition of VM Value management (VM) can be defined as a structured and analytical process, the purpose of which is to seek to achieve value for money by providing all of the necessary functions at the lowest cost consistent with required levels of quality and performance. (AS/NZS 4183, 1994)

  3. Definition of VM (Cont’d) Value = Function / Cost Or Value = Satisfaction of needs / Use of resources

  4. Why is VM? It focuses on briefing stage and design process of projects. It seeks to build consensus and to solve conflicts between project stakeholders. It works for saving time and saving money.

  5. VM workshop VM studies are conducted in the form of workshops which are led by trained facilitators and involve major stakeholders of a project through a structured job plan (Fan et al, 2010). The job plan in VM methodology is often used as a standard to guide the implementation of VM workshops (Norton and McElligott, 1995).

  6. VM Workshop A Standard Job Plan

  7. VM workshop development ? Virtual workshop GDSS GDSS-supported workshop IT software Workshop with IT Face-to-face Nominal workshop

  8. Virtual VM and objectives of the research A GDSS-supported workshop designed to support face-to-face discussion in same location. Virtual VM designed for workshops where participants are geographically dispersed.

  9. Research methods Focus group meetings Experimental studies Questionnaire survey Software engineering

  10. A Virtual VM System (VVMS)

  11. Experiment design 2 Sessions Session A with GDSS Session B with VVMS 4 groups in each Session with same numbers of participants 4 selected Tasks for Creativity Phase

  12. Experiment design (Cont’d) Participants: Masters level students from BRE Participants’ Background:

  13. Experiment design (Cont’d)

  14. Experiment design (Cont’d) The two Sessions used the same facilitation materials and schedule Session A Session B

  15. Number of generated ideas in creativity phase Research findings

  16. 1. A larger number of unique ideas was generated by VVMS-enabled groups than by GDSS-supported groups in a VM workshop; 2. Much higher quality ideas generated by VVMS-enabled groups than by GDSS-supported groups in a VM workshop; and 3. There is a significant difference in satisfaction with a VM workshop between VVMS-enabled groups and GDSS-supported groups. Research findings (Cont’d)

  17. VVMS benefits and drawbacks Benefits: Realized virtual VM Enhanced information sharing Online collaboration Effective creativity in VM Independence in evaluation Drawbacks: Insufficient interaction between participants Cannot work when internet disconnected

  18. Network environment • Schedule is unfair for Session B • Virtual facilitation and activities • Group size Limitations

  19. Thank You Q&A
