Portfolio Management:

Project Portfolio Management (PPM) is the centralized management of processes, technologies and methods used by project management offices (PMOs) and project managers to analyze and collectively organize a group of current or planned projects based on numerous key characteristics. The objectives of PPM are to calculate the optimal resource mix for delivery and to schedule activities to best achieve an organization's financial and operational goals - while honouring constraints imposed by strategic objectives, customers, or external real-world factors.
