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.

최근 건설 환경의 급변화로 인해 건설 프로젝트의 실패 가능성이 높아지고 있다. 이러한 이유로 건설 산업에서는 합리적인 프로젝트 관리전략을 수립하기 위하여 프로젝트의 성과에 영향을 미치는 성공요인에 대한 다각적인 연구가 제시되고 있다. 하지만 프로젝트 성과에 영향을 미치는 요인들의 개선 여부에 따른 혼재로 합리적인 성과관리가 힘든 상황이며, 특히 개선 불가능한 요인인 프로젝트 특성은 성과에 영향을 미치는 독립변수로 성과 도출의 난이도를 결정하게 됨에도 불구하고 이에 대한 연구는 미비한 실정이다. 따라서 본 연구에서는 성과지표와 특성지표체계를 이용하여 성과와 특성간의 영향관계를 밝혀내고 그 결과를 퍼지이론으로 정량화하여 성과 난이도 지수를 산정하며 특성간의 중요도를 고려하여 최종적으로 성과 난이도를 예측하는 연구과정을 수행하였다. 또한 성과 난이도 예측에 있어서 시간과 노력을 절감하여 효율적인 프로젝트 관리 전략을 수립하기 위해서 시공자가 서로 다른 프로젝트의 특성을 입력함에 따라 프로젝트의 각 성과영역에 어떠한 난이도를 갖는지 미리 예측하고 정량적으로 평가할 수 있는 프로젝트 성과 난이도 예측 시스템을 개발하였다.

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.

최근 국내외에서 도시재생사업이 활발히 진행되고 있다. 이러한 도시재생사업은 사업주체 및 이해관계자가 다양하고, 복잡하며, 대규모의 긴 생애주기를 가지고 있다. 또한 대부분 입체 복합공간 개발 형태의 메가프로젝트라는 특징을 나타내고 있다. 이러한 대규모의 도시재생사업은 사업수행과정에서 많은 위험요인들이 존재하며, 그와 더불어 효율적이고 지속적인 성과관리가 필요하다. 그러나 국내의 성과관리는 건설업의 특성을 반영하지 못하고 있으며, 위험과 연계된 연구는 미비하다. 그래서 본 연구는 효율적인 성과관리를 위한 위험과 연계된 성과측정지표를 도출하기 위한 기초연구로 맵핑(mapping)을 통해 성과측정을 위한 성과지표와 위험요인을 연계하는 방법을 제시하고자 한다.

Preproject phase is an important but often ignored research area in information systems field although it has an undeniable importance for successful project. The purpose of this study is to identify factors affecting project performance in preproject phase and to find empirically critical factors among them. After deriving 9 factors through literature review including clear project definition, project leader position, staffing efforts, preproject team expertise, preproject knowledge scope, preproject partnering, top-management support, resource sufficiency, and project climate, the study investigate the influence of those factors on project performance. The study results reveal that clear project definition, project climate, resource sufficiency, pre-project knowledge scope, project leader position have significant impact on project process satisfaction, a measure of project performance, but the other factors do not. Based on the empirical results, the study discuss academic and practical implications.

건설 프로젝트의 대형화, 복잡화에 따라 경쟁력 확보를 위하여 비효율성을 제거하고 합리적인 관리전략 수립을 위한 프로젝트 성과측정의 중요성이 부각되고 있다. 따라서 프로젝트의 성공에 영향을 미치는 요인에 대한 연구가 지속적으로 진행되었으나 이러한 성공요인은 프로젝트 시공자가 성과 증진을 위하여 실행하는 관리방법과 개선할 수 없이 받아 들어야 하는 프로젝트 고유의 특성이 혼재되어 있어 측정된 성과 자료를 벤치마킹하는데 어려움이 있다. 따라서 본 연구에서는 프로젝트의 성과에는 영향을 미치지만 시공자가 개선할 수 없는 요인을 프로젝트 특성으로 정의, 분류하였으며, 특성에 따른 성과증진에 어려움 정도를 프로젝트 관리 실무자 조사를 통하여 정량적으로 평가하였다. 본 연구에서 도출한 프로젝트 성과 난이도 지수로 프로젝트 초기단계의 프로젝트 특성 정보를 활용한 프로젝트 수행의 어려움 정도를 예측할 수 있으며, 프로젝트 시공자의 효율적인 프로젝트 관리를 가능하게 할 것이다.

The tools, methods and measures used for project control reflect underlying theories of management. Management theory has been neglected in the construction industry, which has rather focused on tools and neglected theory. This paper contributes to the theory of project management by introducing and developing two fundamental and competing conceptualizations of management: MBM (Managing-by-Means) and MBR (Managing-by-results). Current project control and performance measurement practice is based on MBR. However, project control based on MBR may not be appropriate for managing dynamic projects. The paper present the Last Planner^TM System (LPS) and Process Variance Control (PVC) as examples of methods reflecting the MBM view. It is argued first that the MBM view is appropriate for managing uncertain, complex and quick projects. The paper also explores how MBR tools and techniques may be appropriately used within an MBM framework.
