This work sheds very little light on the real work of managing project portfolios. Way too much of the text describes basic PM tools such as gantt charts, network diagrams, and work breakdown structures that any decent project manager already knows. Further, use of such tools by themselves does not make a portfolio manager...managing of with organizational strategies/goals and proper management of sponsor and major stakeholder expectations are equally, if not more, important at this level - and this book completely misses this.
