Thank you for the invitation. I agree with the answers shared by the experts!

Project manager drives the project and team members, but if team has conflict with PM, he cannot alone drive the project to success. Most of the companies keep line management different from project management, not to give all authority to PM. A good PM acts like a good leader and motivates its team members.
