Although technology itself is enabling easy management of project execution, failure can still occur, particularly with respect to an ample number unique projects. It argued here that the ampleness uniqueness provide criteria for such be treated differently from smaller-scale enterprises same type. Gaps identified literature regards exact definitions success failure. proposed three main issues impact a project's ecosystem determine its failure, namely, uncertainty, volatility, unknowns. Based on these aspects, future performance estimated correspondingly managed. At time, retrospective assessment or may made rigorous based definitions. Two case studies major presented discussed as examples theory application.
