Abstract
While projects are performed with various challenging troubles, project managers acquire knowledge required for solving such troubles. During this process, project managers may form a structure for problem-awareness. In this study, success criteria or impaired factors for IT projects were structurally modeled as a problem-cognition structure of project managers by means of ISM method. Further, a common problem-cognition structure may be confirmed after evaluating ISM structures generated by twenty one IT-project managers.
