Existing studies tend to agree that there are links among certain key aspects of any project, their systematic enlisting and measurement and directional efforts to improve the performance of project. These aspects are selective and specific and if tracked in a systematic fashion along with necessary corrective action can not only measure any particular project’s performance but also indicate to the higher management in the organization about the approach to be changed in selective area so as to enhance the business success, in general and project’s success in specific. This seminar tends to study various aspects, present a checklist and track sheets along with comments to improve the transmission project’s performance. Transmission being critical activity and among the important services so as to serve the society’s electricity needs, are taken into consideration. A systematically addressed relationship among these criteria and that how these criteria affect the project success is the gist of this seminar. A sincere attempt is made for establishment of relationships of various factors affecting the project’s success and utilizing that relationship for making alert and guiding during project monitoring of Transmission Project. It is concluded that these aspects are not only important to improve project performances on quality, time, cost, and safety, but also critical to appropriately deal with transmission power projects’ externalities for achieving the objectives on project migration, ecological, social and environmental impacts. These results can help Project managers to better understand the relationship between the said aspects and project performance, and encourage them to optimize and take corrective actions for better project outcomes. With support of a case study of 400 KV substation (transmission) project‘s data collected and it has revealed strong correlations between various aspects and project performances.
