Earned Value Management System (EVMS) Reliability: A Review of Existing EVMS Literature

摘要

Supporting project management decisions using an earned value management system (EVMS) brought significant benefits to control schedule and cost for government owners and contractors. However, the lack of a holistic approach in developing and applying an EVMS that is strongly tied to established guidelines tends to cause confusion. This study analyzes existing EVMS studies and suggests management considerations for successful EVMS implementation. Based on a review of literature, this paper identifies a need for improving the reliability of EVMS. Technical guidelines assist in the application of EVM good practices, which can lead to a reliable EVMS. Moreover, the literature review emphasizes that a parallel assessment considering non-technical elements such as the organizations' management culture, is essential to improve reliability.
