The role of a PMO leader can be challenging; unlike the project manager's role, there will be only one PMO leader and not several others. So PMO leaders have to be self-reliant while they carry out their responsibilities alone. An effective PMO leader should possess competencies related to business, leadership, and technology, apart from a passion for the work. Being skilled with business acumen and understanding the laws and regulations of the specific industry is extremely vital, along with practical leadership skills to manage a team. Being technically competent and enthusiastic is also necessary to excel as a PMO leader.
