1. Planning: Project managers work with stakeholders to define project objectives, scope, and deliverables. They create project plans outlining tasks, timelines, resources, and budgets.

2. Organizing: They assemble and lead project teams, assigning roles and responsibilities to team members. This involves identifying skill sets needed for the project and ensuring the right people are in place.

3. Executing: Project managers oversee the implementation of the project plan, monitoring progress, managing resources, and resolving issues or conflicts that arise during the project lifecycle.

4. Monitoring and Controlling: They track project performance against the plan, ensuring that milestones are met, and making adjustments as necessary to keep the project on track. This involves risk management, quality control, and change management.

5. Communication: Project managers facilitate communication among team members, stakeholders, and other relevant parties. They provide regular updates on project status, address concerns, and manage expectations.

6. Problem-solving: Project managers are adept at identifying potential problems or obstacles and finding solutions to keep the project moving forward. This may involve troubleshooting technical issues, resolving conflicts within the team, or adapting to changes in project requirements.

7. Closure: Finally, project managers ensure that all project deliverables are completed to the satisfaction of stakeholders, contracts are closed, and lessons learned are documented for future projects.

Overall, a project manager plays a crucial role in ensuring that projects are delivered successfully, on time, and within budget, while meeting the specified objectives and quality standards.
