The second chapter made an analysis of actual situation of ERP implementation of listed domestic companies, which told us that the high failure rate is a truth, but we are not worse than our international counterparts. After analyzing the common causes of failure from the points of both buyer and seller, we drew a conclusion that the key success factor of ERP includes two parts: successful BPR and advanced project management methodology. The third chapter gave a further introduction about this conclusion. Firstly, we proposed four critical principles to ensure success of BPR, and then highly summarized the content of PMBOK methodology. By mapping critical factors into 5 process groups and 9 knowledge domains of the methodology, we made a detailed analysis of each critical success factor with the help of working practice and experience. The viewpoint of this article was proved practically by study of a positive case and a negative case in the last chapter.
