This paper limited the participation of large corporations in the mass information market by revising the Software Industry Promotion Act in order to increase business opportunity, equality of opportunity, and capacity building for small and medium sized IT companies. However, it is a fact that the medium and small SW companies have insufficient business capacity and expose various problems such as quality degradation of public information business, inadequate risk management, and deterioration of schedule management. In order to solve this problem, this paper derived the factors of quality deterioration in the system integration project and proposed to carry out the project by using some activities of VISUALIZATION, rigorous test management and Agile Methodology as a solution. Applying these measures to healthcare IT projects developed by midsize / small-sized IT companies has improved communications, improved quantitative progress management and improved project visibility. In addition, it contributed to minimizing defect resolution time, improving the requirement coverage ratio, and shortening unnecessary meeting time.

The e-government project management consignment system to allow the public PMO has been introduced to resolve the quality management issue and the business risk, pointed out by the reorganized Software Industry Promotion Act. The additional regulation improvements are demanded because the public PMO system cannot settle down due to the different opinions among related parties: owner, operator and PMO. Therefore, to make balanced regulation improvements, the in-depth studies are necessary to analyze the fundamental causes of the disagreement between the related parties. This study analyses the each related party's cognitive structure to perform public PMO successfully and the fundamental reasons that cause the different opinions by applying the cognitive psychological Means-end chain theory, the laddering technique and the HVM, Hierarchical Value Map. In addition, this study analyses the regulations required for the related parties to obtain the expected benefits.
