In this survey, we perform a survey on different studies associated with critical success factors in project management. The study covers all related studies from 1987 to 2017 based on the arti-cles published on different value added journals. The survey shows that tremendous efforts have been dedicated on important factors, which influence on the success or failure of enterprise re-source planning. The other part of the survey is dedicated for the implementation of Six Sigma projects. Our survey shows that successful implementation of Six Sigma could contribute to the success of projects.
