Abstract
Since 2005, POSCO has been conducting continuous innovation activities using its own innovation methodology, QSS + (Quick Six Sigma Plus). Recently, the effectiveness of QSS + has been decreased owing to the different needs and purposes for each group. The purpose of this study is to compare the weights of the QSS + factors using AHP analysis. QSS + factors consist of two levels. The high level consists of 7 items : 'Master Plan, Waste Zero Activity, Daily Improvement Activity, Talent Development, Project Activity, Initiative/Encouragement activity'. The low level consists of 3 items '5S, My Machine, My M&S' for Daily Improvement Activity. As a result, we found that there was a difference between the weights of the four groups. We suggest the effective QSS + directions to improve the quality of POSCO.
