The 11th Edition maintains the streamlined approach of the prior editions and moves the content even closer to PMIs Project Management Body of Knowledge (PMBOK), the 5th edition of which is scheduled to be released in December 2012.  New content has been added to this edition on measuring project management ROI, value to the organization, and to customers, and much more.  The capstone "super" case on the "Iridium Project" has been maintained covering all aspects of project management.   Increased use of sidebars throughout the book helps further align it with the PMOBOK and the PMP Exam. The 11th edition is supplemented by a Student Workbook, an Instructor's Manual, and a book of case studies to help students learn and prepare for the Project Management Professional (PMP) certification exam.
