A project manager is the person  who has the overall responsibility for the successful initiation,  planning, execution and closure of a project. This title is used in the  construction industry, architecture, and many different occupations that  are based on production of a product or service. The project manager must possess a  combination of skills including an ability to ask penetrating questions,  detect unstated assumptions and resolve interpersonal conflicts as well  as more systematic management skills.
Key amongst his/her duties is the  recognition that risk directly impacts the likelihood of success and  that this risk must be both formally and informally measured throughout  the lifetime of the project. Risk arises primarily from uncertainty  and the successful project manager is the one who focuses upon this as  the main concern. Most of the issues that impact a project arise in one  way or another from risk. A good project manager can reduce risk  significantly, often by adhering to a policy of open communication,  ensuring that every significant participant has an opportunity to  express opinions and concerns.
It follows from the above that a project  manager is one who is responsible for making decisions both large and  small, in such a way that risk is controlled and uncertainty minimised.  Every decision taken by the project manager should be taken in such a  way that it directly benefits the project. Project managers use project management  software, such as Microsoft Project, to organise their tasks and  workforce. These software packages allow project managers to produce  reports and charts in a few minutes, compared to the several hours it  can take if they do not use a software package
