| Abstract |
In order to improve the performance of succeeding superstore construction projects, it is essential to find out an effective way for applying the opportunities of improvement on their repetitive construction process based upon the analysis of various success or failure cases occurred on previous similar projects. This research study suggests a way to improve their construction process through the applications of six sigma techniques on superstore construction projects. A literature review was implemented on the basic concept of six sigma and its general performance steps, and the step by step applications of six sigma techniques were accomplished regarding to the speciality of superstore construction projects. The opportunities of improvement for superstore projects were figured out, and the result of their applications on other superstore projects was analyzed. As a result, it was found that the adoption rate of identical success or failure cases was increased. Also, there were several improvement effects on the projects such as 10~20 days of time savings by projects, decrease of reworks by preventing failure cases, quality and safety improvement. These results indicate that the six sigma techniques are applicable and valuable for improving the repetitive process of superstore construction projects. |
