This lecture introduce on Project Selection and Criteria of Selection Models. Project selection is the process of evaluating individual projects or groups of projects, and then choosing to implement some set of them so that the objectives of the parent organization will be achieved. Managers often use decision-aiding models to extract the relevant issues of a problem from the details in which the problem is embedded. Models represent the problem’s structure and can be useful in selecting and evaluating projects. Finally describe on Project Evaluation Factors.
