As science and technology developed, people in modern society have never stopped stepping forward. Showing rapid increase in social growth and Research and Development (R&D) funding, South Korea have proved that they are also in the middle of this trend. There also have been countless projects so that investors need to know how and where their funds are used. Developers from diverse fields have developed different types of management systems to help monitor and manage their projects. However, the systems are separated from the banking systems, which are in charge of transacting funds. As a result, there have been misuses related to the R&D funding. Realizing the seriousness of those problems, integrated project management systems appeared. The purpose of this paper is to analyze the real issues of managing R&D funding in the existing project management systems and introduce the architecture of the integrated systems.
