Project managers are frequently required to negotiate during the procurement of construction materials and drawing up of contractual agreements. Training in negotiation training requires hands-on experience and interaction with multiple parties. However, in the conventional curriculum on construction management, negotiation is taught merely through lectures and case studies. This study addressed that shortcoming by developing a portfolio negotiation game in which students play different roles and actively make decisions while proceeding through a simulated negotiation process in a competitive context. The proposed game would be the first negotiation game within the domain of the construction industry. During the pilot study, 46 students (with or without industrial working experience) played the game; the results showed an increase in learning interest, satisfaction, and effectiveness.
