  In the project portfolio management, the project selection phase presents the
greatest interest. In this article, we focus on this important phase by
proposing a new method of projects selection consisting of several steps. We
propose as a first step, a classification of projects based on the three most
important criteria namely the value maximization, risk minimization and
strategic alignment. The second step is building alternatives portfolio by the
portfolio managers taking into account the classification of projects already
completed in the first step. The third and final step enables the
identification of the alternative portfolio to consider the contribution of
projects to achieve the organization objectives as well as interactions between
projects.
