Project management is a profession that requires knowledge, skills, abilities and appropriate management tools. Since it is primarily a managerial effort, the project manager might not necessarily be the best technical, professional person but it is essential that he possess general management skills, the most important being the ability to make decisions. A manager who is not capable of decision-making will only slow down the project’s progress. His hesitation will cause the project to suffer delays and overruns and may even lead to failure.
He should also be capable of leading, building a team, working under pressure and communicating with many parties, both within and out of the project.
Finally, the project manager should have a background and expertise in the project’s field so that he will be familiar with the professional content and the related jargon, even if the emphasis is on management skills rather than on technical background in the field.
A good manager will overcome his weaknesses with leadership skills and delegation abilities. In contrast, a person who is not a manager may be overpowered by his weaknesses and harm the project, sometimes severely.
