In the construction industry, bidding competitiveness is the most basic and important competence of the company. Bidding competitiveness comes from competitive advantage, but the strategy of the company to capture bidding competitiveness varies with the characteristics of the project. In particular, overseas construction is where uniqueness of the construction industry and the specificity of international business coexist. This study analyzes the bidding success ratio and the level of bidding difficulty by project characteristics with 12,952 overseas construction bidding cases. Consequently, it was found that the bidding success ratio of Middle East and North Africa (MENA) and civil engineering was the lowest in each group of project characteristics, and therefore the level of bidding difficulty is high, respectively. In addition, it was confirmed that the bidding success ratio of small size or short duration project was relatively high, and the bidding success ratio of both the negotiated bidding in the bidding method group and the private sector in the client type group was respectively high. However, Kruskal-Wallis test in contract type and period shows that there is no statistically significant difference in the bidding success ratio by group.

기존의 조사에 따르면 현재 소프트웨어 개발 프로젝트의 실패율은 높은 편이다. 미국의 The Standish Group의 보고서에 따르면 소프트웨어 프로젝트의 성공률은 약 32%로 낮음을 볼 수 있다. 소프트웨어 프로젝트 성공에 영향을 주는 요소 중 하나는 인력배치이다. 이는 소프트웨어 개발 프로젝트의 참여 인력 구성에 따라 생산성, 비용 및 개발기간이 달라지게 되기 때문이다. 즉 인력 구성에 따라 프로젝트 성공률에 많은 영향을 주게 될 수 있다. 프로젝트 인력할당은 WBS(Work Breakdown Structure)에 따라 PM(Project Manager) 또는 부서장이 할당하게 되는데, 이들은 프로젝트 구성원들의 상세한 정보까지 파악이 어렵기 때문에 인력구성의 어려움이 존재한다. 과거에 수행했던 개발 프로젝트에서 유사성이 높은 작업을 했음에도 불구하고 전혀 경험이 없는 작업에 할당되면 상대적으로 업무 지식습득에 어려움을 겪고 시간 지연에 따른 비용이 추가적으로 발생하게 된다. 이러한 문제를 해결하고자 본 연구는 소프트웨어 개발 프로젝트 구성원의 상세한 정보들과 소프트웨어 개발 업무와의 유사도 측정을 통해 인력을 업무에 할당하는 기법을 제안한다. 이를 위하여 제안한 기법을 프로토타입으로 구현한 후 현업에서 실제 개발되는 프로젝트에 적용하여 제안 기법의 우수함을 평가한다.

Recently, the public sector information projects have bebn larger in size, sophisticated, and diversified, which make the performance management model be studied continuously. According to the research and understanding on this, there are discontents resulted from poor requirements managements, schedule delays, budget overruns, failure to achieve expected goals, although there are increase the scale of projects and the number of information systems than ever before. it makes the requirement for the plan to manage significant risk factors systematically. So in this study, we will understand the risks which have been recognized by professionals and managers in public sector projects for enhancing the success rate. And the surveys will be conducted for the risk factors in each fields by gathering the opinions of the hands on workers in public sector project support team such as S company, L company. Finally, the correlation index between the risks and the other project fields would be clear by this survey.

As the software complexity increases, the development success rate decreases and failure rate increases exponentially. The failure rate related to the software size can be described by a growth function. Based on this phenomenon, this paper estimates the development success and completion rate using the Gompertz growth function. At first, we transformed a software size of numerically suggested $10^n$ into a logarithm and kept the data interval constantly. We tried to derive a functional relationship between the development success rate and the completion rate according to the change of logarithmic software size. However, we could not find a function which can represent this relationship. Therefore, we introduced the failure rate and the cancel rate which are inverse to the development success rate and completion rate, respectively. Then, we indicated the relation between development failure rate and cancel rate based on the change of software size, as a type of growth function. Finally, as we made the Gompertz growth function with the function which describes the cancel rate and the failure rate properly. We could express the actual data suitably. When you apply the growth function model that I suggested, you will be able to get the success rate and completion rate of particular site of software very accurately.

In 2009, the Korean international construction industry showed a great performance, totaling 49.1 billion of contract and then this achievement has been considered a key milestone presenting that the international construction industry is one of the primary export industries of Korea. However, because of the construction firms' equalized levels of technology and price competitiveness, the competition among bidders is becoming more intensive. Moreover, this changing market circumstance leads construction firms to apply for bidding with the lowest price that could not meet the expected profitability of a project. Therefore, to develop various strategies based on project characteristics becomes one of the critical capabilities that construction firms should possess. Based on these motives, this study is aimed to investigate associations among number of bidders, contract award rate, profitability on international projects. For the correlation analysis, a set of data is structured by collecting all projects ranging from 1993 to 2009, excluding projects funded by official development and domestic funds. The number of bidders were grouped depending on project characteristics such as market regions, project types, bidding types, and order organization types. As the result of correlation analysis, contract award rate increases as the number of bidders increase, but the relationship between the number of bidders and profitability is negative. Understanding the correlations among variables can be employed in developing strategies to improve construction firms' competitiveness in the international construction market.

Project Financing (PF) development project is the type which influences national economy and building industry largely because it is exerted by using borrowed money from many kinds of investors and huge amount of financial raising. Many domestic PF projects are focused mainly on the profit maximization lacking in a sufficient feasibility study. Nowadays many projects are suspending due to the global finance debacle and stagnation of real estate industry. Therefore, in this paper, risk factors of PF project are deducted and Key Success Factors (KSFs) are derived through Factor-Analysis and qualified using Fuzzy-AHP method. And through the evaluation of the derived success factors in real projects, a strong correlationship has been identified between the score of each PF success factor and the level of success and/or expected rate of return (ROR). So, the result of this paper can help decision makers of the PF projects make a better decision and give a meaningful guidance in achieving successful PF projects.

This study aims to find out success factors of crowdfunding on movie projects. For empirical analysis, we collected 583 data of the movie projects from the crowdfunding platform 'Tumblbug'. To figure out the success factors, we examined effects of 10 independent variables on 1 dependent variable. The independent variable includes target amount, project information, reward options, creator funding power, editor recommendation, creator contents power, movie type, number of comments, number of replies, and number of SNS information. The final achievement rate of crowdfunding was set as dependent variable. This study found that the target amount, number of text information, number of video information, editor recommendation, number of backers' reply, and number of SNS information had a significant impact on the achievement rate of the movie crowdfunding project. This study has implications in that it has discovered a variable of editor recommendation and the number of SNS information, and both of them have a positive effect on crowdfunding achievement.
