PMBOK Guide: A Guide to the Project Management Body of Knowledge Reviews
The PMBOK Guide is the very basic material every PM has to read to prepare for the PMP exam. It contains all the body of knowledge, tools, and processes in project management. A lot of questions in the exam will come from this book. Study it thoroughly, and remember all the processes, inputs, outputs, and tools for each knowledge area. Digest the diagrams and understand how and why they're there. This book is the single most important material in passing the PMP certification.
PMBOK is the main reference book. Although it's difficult to study and grab the knowledge from the book but it's the main resource and handbook for all Project Managers. It briefly describes and defines all the knowledge areas and Inputs, Outputs, Tools and Techniques. Anyone who is preparing for the exam, this book alone is not enough but it's important along with all other books. The book is useful in understanding and remembering the definition of different concepts.
The book has no questions and answers for practice. Also it does not have any kind of practice exercises, and that is why this book is a good reference book but not a good exam preparation book. I would recommend this book for definition and to have a quick look on ITTO.
This is like a bible. Every concept is well explained and it is a must read. In fact every line must be carefully read. ITTO is well covered in this book.
I read the majority of the PMBOK prior to my Cheetah class. I found just reading the PMBOK was tedious and not very helpful for preparing for the course. If I had not been taking a prep class, I probably could have studied the book in more depth to prepare for the test.
The PMBOK is a dry encyclopedia of PMI PM concepts. It provides a framework and description of process areas, inputs and outputs and structure on what is tested etc. The real value I got from the PMBOK was understanding the Inputs, tools & techniques and Outputs that go into a PM Process, e.g.
Inputs: Project Management plan; approved change requests; enterprise environmental factors; organizational process assets
Tools & techniques: Expert judgement; project management info system
Outputs: Deliverable, WPI, Change requests, project document updates etc
The PMP exam tests the sequence of these, inputs/outputs quite frequently.
The book provides excellent ideas on all the areas of project management. It has great work ethics and step by step procedure to learn project management.
