This book is written by ten members of the Enterprise Portfolio Management Council who come from a range of businesses and industries. The authors write from their perspectives "from the trenches" and talk to their peers about how each step of the portfolio management process works. The book begins with the basics of what portfolio management is and why its critical to the success of a business. From there the book walks through each part of the process using cases and examples from the authors' own experience to illustrate successful and unsuccessful processes.
