Many studies have been published on the relationship between project management styles and project performance. In recent researches, it is argued that project management styles should be different based on project characteristics and these project characteristics may have an effect on the relationship between project management styles and project performance. However, there are few empirical studies covering these issues. In this study, we examined the effect of project characteristics (i.e., degree of newness) on the relationship between project management styles (i.e., team autonomy, internal and external communication, individualism orientation) and project performance. The empirical results using 78 government sponsored R&D projects showed that team autonomy has a stronger positive effect on project performance as project newness becomes higher. In addition, as project newness becomes higher, internal communication showed a stronger positive effect on project performance, while external communication had a stronger negative effect.

Risk-based estimation has been successfully introduced into the construction industry. By incorporating historical data associated with probability analysis, risk-based estimate is an effective decision support aid in considering whether to launch a particular project. The industry challenges, however, especially related with management issues, such as labor shortage, wage growth, and supply chain complexity, have often resulted in poor cost performance. The insufficient assessing the project characteristics (i.e., resource availability, project complexity, and project delivery method) can be the main reasons in the poor cost performance. Because the accuracy level of cost performance prediction can be enhanced by extensive evaluation of the subject project characteristics, a new approach for predicting cost performance in an earlier stage of a project can improve the Industry substantiality, in other words, value maximization. The purpose of this paper is to develop a new methodology in developing a risk-based estimate tool by incorporating extensive project characteristics. To do this, an extensive industry survey was conducted from both private and public sectors in building industry in Korea. In addition, significant project characteristics were identified in terms of cost performance indicator. Although the data collection is limited to Korean industry the suggested approach provides the industry with a straightforward methodology in risk management. As many researchers maintained that front-end planning efforts are crucial in achieving the successful outcome in building projects, the new method for risk-based estimation can Improve the cost performance as well as enhance the fulfillment in terms of business sustainability.

Currently, The failure of construction project is increasing to be caused by a changing construction environment. According to this circumstances, Researches of project success factors affecting performance have been presented to develop strategies for efficient construction project management in the construction industry. However, Conducting efficient construction project management is difficult because project manager could not know which project success factors can be improved or not. Especially, although the project characteristics were derived the level of difficulty for performance, research of the project characteristics which could not be improved as influence factor to performance is lacking. Therefore, This paper has developed the Performance Predicting System(PPS) with Fuzzy set theory to establish. PPS has been developed to establish efficient project management strategies and to save time and effort. As Contractor inputs the project characteristics, PPS can predict the level of difficulty of performance.

Purpose: The purpose of this study is to analyze the effects of risk perception and opportunistic behavior on project performance and the moderating effect of cooperation in this relationship through literature review to identify factors affecting the performance of large-scale nuclear power plant construction projects. Methods: This study conducted a survey on nuclear power plant construction project participants and verified the hypothesis using statistical methods. Results: The results of this study are as follows; First, risk perception appeared to have a positive effect on opportunistic behavior, and it was confirmed that opportunistic behavior among participating companies could occur even in nuclear power plant construction projects. Second, it has been proven that risk perception has a negative effect on project performance as suggested in previous studies. Third, in the relationship between opportunistic behavior and project performance, it was found that opportunistic behavior had a negative effect on project performance. Finally, cooperation was found to have a moderating effect on the relationship between performance risk and project performance. Conclusion: This study is a case of empirical analysis targeting nuclear power plant construction project workers, and provided a basis for reference in future related academic research and project implementation.

The purpose of the research is to propose an integrated project planning process and its implementation method. Although there is increasing interest in the application of the Earned Value Management(EVM) method in the project management area, the progress and maturity of the technical performance have not been included in assessing the Earned Value. The main concept of the planning process is to use cost, schedule, as well as the technical performance in the assessment of the Earned Value Management for Military R&D project management practices. The resulting process can enhance the efficiency of the project work by eliminating the currently duplicated activities between traditional project planning process and the newly implemented Earned Value Management process and by shortening the early planning process duration of projects adopting EVM practices.

Recently, the importance of project management has increased due to the scale and complexity of the construction projects. Therefore, this study conducted a survey on construction companies and related public institutions to verify the relationship between the role of the Project Management Office(PMO) and PM leadership for project performance. Based on this, the effect of the PMO role on the project performance was identified and the moderating effect of PM leadership was analyzed. As a result, first, the role of the PMO was found to have an influential on the project performance. Second, the PM leadership was verified to has a moderating effect in the relationship between the PMO role and the project performance. The purpose of this study is to analyze the influential of the role of PMO on project performance in the construction industry to suggest the necessity of PMO in the construction industry and the need to adopt PMO in large-scale construction projects and analyze the moderating effect of PM leadership on project performance.

Recently, the urban regeneration project has been performed actively at home and abroad. The stake-holders in urban regeneration project are various and complicated, and has large scale during a long life period. Also they show the characteristics of a mega-project and most mixed-use form. Therefore, the urban regeneration has a lot of potential risk factors from project beginning to completion. It means they need efficient and continuous risk management in terms of performance measurement. But the current domestic construction project does not reflect risk management in view of performance measurement. This study proposes the risk management methodology by mapping risk factors with major performance indexes of the urban regeneration project.

Since the larger and complex construction projects are performed, project performance measurement is highlighting the importance to eliminate inefficiencies and plan to reasonable management practices. So many researchers are conducting research about the project critical sucess factor. But, these factors are mixed both management practices to improve performance and native project characteristics. Therefore performance measurement data couldn't apply to another project successfully. And the project characteristics affect project performance. But contractor couldn't change characteristics. This study provides a project characteristics's definition and classification. This study provides a quantitative level of performance improvement difficulty through out project manager survey. The contractor can estimate a level of performance difficulty through initial project information. With this, project contractor can more efficiently manage project.
