Portfolio Management HW

Q1. In any organization, projects could be both internal and external. Internal projects are executed  to enhance capability and/or capacity of an organization and are sourced from within the  organization. Whereas external projects are executed for clients external to the organization. Give  examples of both internal and external projects for an organization. Also explain with justifications  and examples if Project Portfolio Management (PPM) would be applicable for only the selection  of external projects or for selecting both types of projects? 

Q2. A project charter is ideally developed for each project. What is a project charter and what  possible assistance can a project charter provide in PPM and how? 

Q3. What are the differences in the focus of “Project Management (PM)” and “PPM” over the  PPM lifecycle? What performance measures can be used to evaluate a project from the perspective  of PM and PPM?
