Welcome to the tenth edition of PMP® Exam Prep. It's been 20 years since Rita published the first
edition of this book. RMC has come far since the publication of the first edition back in 1998, as has the
project management profession.

Back when the first edition was published, most project managers were in the United States. Now
there are more international project managers than ever before. As a result of this industry growth, RM C's
best-selling materials are now sold all over the world.

Project management is also a more complex profession than it used to be. Along with the processes,
concepts, tools, and techniques that were added within the last couple of years, there are now just as many
adaptive approaches to project management as there are predictive. The general methodologies and overall
practices of project management have changed dramatically, which has increased the size of a project
manager's toolbox.

These updates have resulted in changes to the exam. There is more to learn today than ever. This
increased complexity is reflected in the tenth edition of our best-selling PMP Exam Prep book.

First, and one of the more significant changes, is the introduction of three new domains within which
project management exists: People (Domain I), Process (Domain II), and Business Environment (Domain
III). What does this mean for the process groups of initiating, planning, executing, monitoring and
controlling, and closing? That's a great question, and we have you covered. Our new and improved chapter
three, now titled "Processes and Domains," addresses both the process groups as well as each of the three
domains in a clear and easy-to-read format that will prepare you to not only understand the groups and
domains, but will give you all of the knowledge you need to pass the exam.

Another big change is the acknowledgement of the importance of PMI's Examination Content Outline
(ECO). It is now more important than ever to read and understand the ECO as it covers the domains and
introduces adaptive approaches to project management and the PMP exam. Throughout each chapter of
the tenth edition of this book, we've included agile terms and concepts. You may see these terms and
concepts on the exam, but you also need to know them to become a more adaptive project manager.

While these are significant changes, important aspects of our book remain the same. First, and most
importantly, is the conversational tone of the book. The tenth edition maintains its down-to-earth
conversational style-explaining things simply and clearly. Students say that when they read this book, it
feels like Rita is talking to them. In many ways, she still is.
