Project Portfolio Management (PPM) is a management process designed to help an organization acquire and view information about all of its projects, then sort and prioritize each project according to certain criteria, such as strategic value, impact on resources, cost, and so on.
The objectives of PPM are similar to the objectives of managing a financial portfolio:
1) To become conscious of all the individual listings in the portfolio
2) To develop a "big picture" view and a deeper understanding of the the collection as a whole. 3) To allow sensible sorting, adding, and removing of items from the collection based on their costs, benefits, and alignment with long-term strategies or goals.
4) To allow the portfolio owner to get the "best bang for the buck" from resources invested.
