Based on extensive literature review, this theoretical paper adds to the “soft skill” research stream by enlarging the scope of personality dimensions and their subsequent effects on project success and, second, considers dimensions heretofore not explored within the project management body of knowledge. We posit that a project manager's extent of communication apprehension, degree of innovativeness, level of self‐monitoring, conflict management style, degree of change orientation and Myers‐Briggs (MBTI) personality type can affect project outcomes. Additionally, we conjecture that organizational dynamics such as structure, incentive systems, and organizational project management maturity can moderate the relationship between these personality dimensions and project success.
