What is a project manager?
A project manager is an organizer, a coordinator. The quarterback. The nexus of the project. A jack of all trades. While specialists use their skills and experience to create specialist products (deliverables), project managers need general management skills, some knowledge about what each specialist does, and a knack for problem-solving.
A project manager is…a leader/manager. The one who takes charge of the project. The liason to the stakeholders.
