This document discusses the seven deadly sins of poor project portfolio management (PPM) implementation. It begins by defining PPM and describing its benefits, such as linking projects to strategy and balancing project risk. It then outlines seven common sins that can undermine a PPM implementation: pride, envy, gluttony, lust, anger, greed, and sloth. For each sin, it provides an example of how that mindset or behavior can negatively impact PPM. The document stresses that successful PPM requires balancing people, processes and technology, and avoiding actions like resisting change or trying to implement everything at once.
