The key competencies of a project manager are immense but a few of them are mentioned within the length of this paper.Within the literature review for this topic, the emphasis would be laid on the fact that project managers commit their own selves whole-heartedly towards the cause of the project at hand and that they exhibit some of the very intrinsic traits within their professional duties and their personal capacities which make them stand head and shoulders with the rest of the employees within the organization. It is their single-ness in terms of management expertise which is given its due credit and thus they are appointed as the ones who will lead the organization towards success whilst accomplishing the results that are envisaged in the wake of a peculiar project.
